INTRODUCTION
1. Introduction
This section presents a brief overview of the SATA RAID Series
controller, ARC-1110/1110ML/1120/1120ML/1130/1130ML/1160/
1160ML/1170 (4/8/12/16/24-port PCI-X SATA RAID Controllers) and
ARC-1210/1220/1230/1230/1231ML/1260/1261ML/1280/1280ML
(4/8/12/16/24-port PCI-Express SATA RAID Controllers).
1.1 Overview
The ARC-11xx and ARC-12xx Series of high-performance Serial ATA
RAID controllers support a maximum of 4, 8, 12, 16, or 24 SATA
II peripheral devices (depending on model) on a single controller.
The ARC-11xx series for the PCI-X bus and the ARC-12xx Series
for the PCI-Express bus. When properly configured, these SATA
controllers provide non-stop service with a high degree of fault
tolerance through the use of RAID technology and can also provide
advanced array management features.
The 4 and 8 port SATA RAID controllers are low-profile PCI cards,
ideal for 1U and 2U rack-mount systems. These controllers utilize
the same RAID kernel that has been field-proven in Areca existing
external RAID controllers, allowing Areca to quickly bring stable
and reliable RAID controllers to the market.
Unparalleled Performance
The SATA RAID controllers provide reliable data protection for
desktops, workstations, and servers. These cards set the standard with enhancements that include a high-performance Intel I/O
Processor, a new memory architecture, and a high performance PCI
bus interconnection. The 8/12/16/24-port controllers with the RAID
6 engine built-in can offer extreme-availability RAID 6 functionality.
This engine can concurrently compute two parity blocks with performance very similar to RAID 5. The controllers by default support
256MB of ECC SDRAM memory. The 12/16/24 port controllers support one DDR333 SODIMM socket that allows for upgrading up to
1GB of memory. The 12/16/24 port controllers support one DDR2533 DIMM socket that allows for upgrading up to 2GB of memory.
The controllers use Marvell 4/8 channel SATA PCI-X controller

INTRODUCTION
chips, which can simultaneously communicate with the I/O processor and read or write data on multiple drives.
Unsurpassed Data Availability
As storage capacity requirements continue to rapidly increase, users require greater levels of disk drive fault tolerance, which can be
implemented without doubling the investment in disk drives. RAID
1 (mirroring) provides high fault tolerance. However, half of the
drive capacity of the array is lost to mirroring, making it too costly
for most users to implement on large volume sets due to dobuling
the number of drives required. Users want the protection of RAID 1
or better with an implementation cost comparable to RAID 5. RAID
6 can offer fault tolerance greater than RAID 1 or RAID 5 but only
consumes the capacity of 2 disk drives for distributed parity data.
The 8/12/16/24-port RAID controllers provide RAID 6 functionality
to meet these demanding requirements.
The SATA RAID controllers also provide RAID levels 0, 1, 1E, 3, 5
or JBOD configurations. Its high data availability and protection is
derived from the following capabilities: Online RAID Capacity Expansion, Array Roaming, Online RAID Level / Stripe Size Migration,
Dynamic Volume Set Expansion, Global Online Spare, Automatic
Drive Failure Detection, Automatic Failed Drive Rebuilding, Disk
Hot-Swap, Online Background Rebuilding and Instant Availability/Background Initialization. During the controller firmware flash
upgrade process, it is possible that an error results in corruption of
the controller firmware. This could result in the device becoming
non-functional. However, with our Redundant Flash image feature,
the controller will revert back to the last known version of firmware
and continue operating. This reduces the risk of system failure due
to firmware crashes.
Easy RAID Management
The SATA RAID controller utilizes built-in firmware with an embedded terminal emulation that can access via hot key at BIOS bootup screen. This pre-boot manager utility can be used to simplify
the setup and management of the RAID controller. The controller
firmware also contains a ArcHttp browser-based program that can
be accessed through the ArcHttp proxy server function in Windows,
11
INTRODUCTION
Linux, FreeBSD and more environments. This Web browser-based
RAID management utility allows both local and remote creation and
modification RAID sets, volume sets, and monitoring of RAID status
from standard web browsers.

1.3 RAID Concept
1.3.1 RAID Set
A RAID set is a group of disks connected to a RAID controller. A
RAID set contains one or more volume sets. The RAID set itself
does not define the RAID level (0, 1, 1E, 3, 5, 6, etc); the RAID
level is defined within each volume set. Therefore, volume sets are
contained within RAID sets and RAID Level is defined within the
volume set. If physical disks of different capacities are grouped
together in a RAID set, then the capacity of the smallest disk will
become the effective capacity of all the disks in the RAID set.
1.3.2 Volume Set
Each volume set is seen by the host system as a single logical device (in other words, a single large virtual hard disk). A volume set
will use a specific RAID level, which will require one or more physical disks (depending on the RAID level used). RAID level refers to
the level of performance and data protection of a volume set. The
capacity of a volume set can consume all or a portion of the available disk capacity in a RAID set. Multiple volume sets can exist in a
RAID set.
For the SATA RAID controller, a volume set must be created either
on an existing RAID set or on a group of available individual disks
(disks that are about to become part of a RAID set). If there are
pre-existing RAID sets with available capacity and enough disks for
the desired RAID level, then the volume set can be created in the
existing RAID set of the user’s choice.
15
INTRODUCTION
In the illustration, volume 1 can be assigned a RAID level 5 of
operation while volume 0 might be assigned a RAID level 1E of
operation. Alterantively, the free space can be used to create volume 2, which could then be set to use RAID level 5.
1.3.3 Ease of Use Features
1.3.3.1 Foreground Availability/Background Initialization
RAID 0 and RAID 1 volume sets can be used immediately after creation because they do not create parity data. However,
RAID 3, 5 and 6 volume sets must be initialized to generate
parity information. In Backgorund Initialization, the initialization proceeds as a background task, and the volume set is fully
accessible for system reads and writes. The operating system
can instantly access the newly created arrays without requiring a reboot and without waiting for initialization to complete.
Furthermore, the volume set is protected against disk failures
while initialing. If using Foreground Initialization, the initialization process must be completed before the volume set is ready
for system accesses.
1.3.3.2 Array Roaming
The SATA RAID controllers store RAID configuration information
on the disk drives. The controller therefore protect the configuration settings in the event of controller failure. Array roaming
allows the administrators the ability to move a completele RAID
set to another system without losing RAID configuration infor-
16
INTRODUCTION
mation or data on that RAID set. Therefore, if a server fails, the
RAID set disk drives can be moved to another server with an
Areca RAID controller and the disks can be inserted in any order.
1.3.3.3 Online Capacity Expansion
Online Capacity Expansion makes it possible to add one or more
physical drives to a volume set without interrupting server operation, eliminating the need to backup and restore after reconfiguration of the RAID set. When disks are added to a RAID set,
unused capacity is added to the end of the RAID set. Then, data
on the existing volume sets (residing on the newly expanded
RAID set) is redistributed evenly across all the disks. A contiguous block of unused capacity is made available on the RAID set.
The unused capacity can be used to create additional volume
sets.
A disk, to be added to a RAID set, must be in normal mode (not
failed), free (not spare, in a RAID set, or passed through to
host) and must have at least the same capacity as the smallest
disk capacity already in the RAID set.
Capacity expansion is only permitted to proceed if all volumes
on the RAID set are in the normal status. During the expansion
process, the volume sets being expanded can be accessed by
the host system. In addition, the volume sets with RAID level 1,
1E, 3, 5 or 6 are protected against data loss in the event of disk
failure(s). In the case of disk failure, the volume set transitions
from “migrating” state to “migrating+degraded“ state. When the
expansion is completed, the volume set would then transition to
“degraded” mode. If a global hot spare is present, then it further
transitions to the “rebuilding” state.
17
INTRODUCTION
The expansion process is illustrated as following figure.
The SATA RAID controller redistributes the original volume set
over the original and newly added disks, using the same faulttolerance configuration. The unused capacity on the expand
RAID set can then be used to create an additional volume set,
with a different fault tolerance setting (if required by the user.)
The SATA RAID controller redistributes the original volume set
over the original and newly added disks, using the same faulttolerance configuration. The unused capacity on the expand raid
set can then be used to create an additional volume sets, with a
different fault tolerance setting if user need to change.
18
INTRODUCTION
1.3.3.4 Online RAID Level and Stripe Size Migration
For those who wish to later upgrade to any RAID capabilities, a
system with Areca online RAID level/stripe size migration allows
a simplified upgrade to any supported RAID level without having
to reinstall the operating system.
The SATA RAID controllers can migrate both the RAID level and
stripe size of an existing volume set, while the server is online and the volume set is in use. Online RAID level/stripe size
migration can prove helpful during performance tuning activities
as well as when additional physical disks are added to the SATA
RAID controller. For example, in a system using two drives in
RAID level 1, it is possible to add a single drive and add capacity and retain fault tolerance. (Normally, expanding a RAID level
1 array would require the addition of two disks). A third disk
can be added to the existing RAID logical drive and the volume
set can then be migrated from RAID level 1 to 5. The result
would be parity fault tolerance and double the available capacity
without taking the system down. A forth disk could be added to
migrate to RAID level 6. It is only possible to migrate to a higher
RAID level by adding a disk; disks in an existing array can’t be
reconfigured for a higher RAID level without adding a disk.
Online migration is only permitted to begin, It all volumes to be
migrated are in the normal mode. During the migration process,
the volume sets being migrated are accessed by the host system. In addition, the volume sets with RAID level 1, 1E, 3, 5 or
6 are protected against data loss in the event of disk failure(s).
In the case of disk failure, the volume set transitions from migrating state to (migrating+degraded) state. When the migration is completed, the volume set transitions to degraded mode.
If a global hot spare is present, then it further transitions to
rebuilding state.
1.3.3.5 Online Volume Expansion
Performing a volume expansion on the controller is the process
of growing only the size of the lastest volume. A more flexible
option is for the array to concatenate an additional drive into the
RAID set and then expand the volumes on the fly. This happens
19
INTRODUCTION
transparently while the volumes are online, but, at the end of
the process, the operating system will detect free space at after
the existing volume.
Windows, NetWare and other advanced operating systems support volume expansion, which enables you to incorporate the
additional free space within the volume into the operating system partition. The operating system partition is extended to
incorporate the free space so it can be used by the operating
system without creating a new operating system partition.
You can use the Diskpart.exe command line utility, included with
Windows Server 2003 or the Windows 2000 Resource Kit, to extend an existing partition into free space in the dynamic disk.
Third-party software vendors have created utilities that can be
used to repartition disks without data loss. Most of these utilities
work offline. Partition Magic is one such utility.
1.4 High availability
1.4.1 Global Hot Spares
A Global Hot Spare is an unused online available drive, which is
ready for replacing the failure disk. The Global Hot Spare is one
of the most important features that SATA RAID controllers provide
to deliver a high degree of fault-tolerance. A Global Hot Spare
is a spare physical drive that has been marked as a global hot
spare and therefore is not a member of any RAID set. If a disk
drive used in a volume set fails, then the Global Hot Spare will
automatically take its place and he data previously located on the
failed drive is reconstructed on the Global Hot Spare.
For this feature to work properly, the global hot spare must have
at least the same capacity as the drive it replaces. Global Hot
Spares only work with RAID level 1, 1E, 3, 5, or 6 volume set.
You can configure up to three global hot spares with ARC-11xx/
12xx.
The Create Hot Spare option gives you the ability to define a
20
INTRODUCTION
global hot spare disk drive. To effectively use the global hot
spare feature, you must always maintain at least one drive that
is marked as a global spare.
Important:
The hot spare must have at least the same capacity as the
drive it replaces.
1.4.2 Hot-Swap Disk Drive Support
The SATA controller chip includes a protection circuit that supports
the replacement of SATA hard disk drives without having to shut
down or reboot the system. A removable hard drive tray can deliver “hot swappable” fault-tolerant RAID solutions at prices much
less than the cost of conventional SCSI hard disk RAID controllers. This feature provides advanced fault tolerant RAID protection
and “online” drive replacement.
1.4.3 Auto Declare Hot-Spare
If a disk drive is brought online into a system operating in degraded mode, The SATA RAID controllers will automatically declare the new disk as a spare and begin rebuilding the degraded
volume. The Auto Declare Hot-Spare function requires that the
smallest drive contained within the volume set in which the failure
occurred.
In the normal status, the newly installed drive will be reconfigured
an online free disk. But, the newly-installed drive is automatically
assigned as a hot spare if any hot spare disk was used to rebuild
and without new installed drive replaced it. In this condition, the
Auto Declare Hot-Spare status will disappeared if the RAID subsystem has since powered off/on.
The Hot-Swap function can be used to rebuild disk drives in arrays
with data redundancy such as RAID level 1, 1E, 3, 5, and 6.
21
INTRODUCTION
1.4.4 Auto Rebuilding
If a hot spare is available, the rebuild starts automatically when
a drive fails. The SATA RAID controllers automatically and transparently rebuild failed drives in the background at user-definable
rebuild rates.
If a hot spare is not available, the failed disk drive must be replaced with a new disk drive so that the data on the failed drive
can be automatically rebuilt and so that fault tolerance can be
maintained.
The SATA RAID controllers will automatically restart the system
and the rebuild process if the system is shut down or powered off
abnormally during a reconstruction procedure condition.
When a disk is hot swapped, although the system is functionally
operational, the system may no longer be fault tolerant. Fault
tolerance will be lost until the removed drive is replaced and the
rebuild operation is completed.
During the automatic rebuild process, system activity will continue as normal, however, the system performance and fault tolerance will be affected.
1.4.5 Adjustable Rebuild Priority
Rebuilding a degraded volume incurs a load on the RAID subsystem. The SATA RAID controllers allow the user to select the
rebuild priority to balance volume access and rebuild tasks appropriately. The Background Task Priority is a relative indication of
how much time the controller devotes to a background operation,
such as rebuilding or migrating.
The SATA RAID controller allows user to choose the task priority
(Ultra Low (5%), Low (20%), Medium (50%), High (80%)) to balance volume set access and background tasks appropriately. For
high array performance, specify an Ultra Low value. Like volume
initialization, after a volume rebuilds, it does not require a system
reboot.
22
INTRODUCTION
1.5 High Reliability
1.5.1 Hard Drive Failure Prediction
In an effort to help users avoid data loss, disk manufacturers are
now incorporating logic into their drives that acts as an "early
warning system" for pending drive problems. This system is called
S.M.A.R.T. The disk integrated controller works with multiple
sensors to monitor various aspects of the drive's performance,
determines from this information if the drive is behaving normally
or not, and makes available status information to RAID controller
firmware that probes the drive and look at it.
The SMART can often predict a problem before failure occurs.
The controllers will recognize a SMART error code and notify the
administer of an impending hard drive failure.
1.5.2 Auto Reassign Sector
Under normal operation, even initially defect-free drive media can
develop defects. This is a common phenomenon. The bit density
and rotational speed of disks is increasing every year, and so is
the potential of problems. Usually a drive can internally remap
bad sectors without external help using cyclic redundancy check
(CRC) checksums stored at the end of each sector.
SATA drives perform automatic defect re-assignment for both
read and write errors. Writes are always completed - if a location
to be written is found to be defective, the drive will automatically
relocate that write command to a new location and map out the
defective location. If there is a recoverable read error, the correct data will be transferred to the host and that location will be
tested by the drive to be certain the location is not defective. If
it is found to have a defect, data will be automatically relocated,
and the defective location is mapped out to prevent future write
attempts.
In the event of an unrecoverable read error, the error will be
reported to the host and the location flagged as potentially defective. A subsequent write to that location will initiate a sector test
and relocation should that location have a defect. Auto Reassign
Sector does not affect disk subsystem performance because it
23
INTRODUCTION
runs as a background task. Auto Reassign Sector discontinues
when the operating system makes a request.
1.5.3 Consistency Check
A consistency check is a process that verifies the integrity of
redundant data. For example, performing a consistency check
of a mirrored drive assures that the data on both drives of the
mirrored pair is exactly the same. To verify RAID 3, 5 or 6 redundancy, a consistency check reads all associated data blocks, computes parity, reads parity, and verifies that the computed parity
matches the read parity.
Consistency checks are very important because they detect and
correct parity errors or bad disk blocks in the drive. A consistency
check forces every block on a volume to be read, and any bad
blocks are marked; those blocks are not used again. This is critical and important because a bad disk block can prevent a disk
rebuild from completing. We strongly recommend that you run
consistency checks on a regular basis—at least once per week.
Note that consistency checks degrade performance, so you should
run them when the system load can tolerate it.
1.6 Data Protection
1.6.1 BATTERY BACKUP
The SATA RAID controllers are armed with a Battery Backup Module (BBM). While a Uninterruptible Power Supply (UPS) protects
most servers from power fluctuations or failures, a BBM provides
an additional level of protection. In the event of a power failure, a
BBM supplies power to retain data in the RAID controller’s cache,
thereby permitting any potentially dirty data in the cache to be
flushed out to secondary storage when power is restored.
The batteries in the BBM are recharged continuously through a
trickle-charging process whenever the system power is on. The
batteries protect data in a failed server for up to three or four
days, depending on the size of the memory module. Under normal operating conditions, the batteries last for three years before
replacement is necessary.
24
INTRODUCTION
1.6.2 RECOVERY ROM
The SATA RAID controller firmware is stored on the flash ROM and
is executed by the I/O processor. The firmware can also be updated through the PCI-X/PCIe bus port or Ethernet port (if equipped)
without the need to replace any hardware chips. During the controller firmware upgrade flash process, it is possible for a problem
to occur resulting in corruption of the controller firmware. With
our Redundant Flash Image feature, the controller will revert back
to the last known version of firmware and continue operating.
This reduces the risk of system failure due to firmware crash.
1.7 Understanding RAID
RAID is an acronym for Redundant Array of Independent Disks. It
is an array of multiple independent hard disk drives that provides
high performance and fault tolerance. The SATA RAID controller implements several levels of the Berkeley RAID technology.
An appropriate RAID level is selected when the volume sets are
defined or created. This decision should be based on the desired
disk capacity, data availability (fault tolerance or redundancy),
and disk performance. The following section discusses the RAID
levels supported by the SATA RAID controller.
The SATA RAID controller makes the RAID implementation and
the disks’ physical configuration transparent to the host operating
system. This means that the host operating system drivers and
software utilities are not affected, regardless of the RAID level
selected. Correct installation of the disk array and the controller requires a proper understanding of RAID technology and the
concepts.
1.7.1 RAID 0
RAID 0, also referred to as striping, writes stripes of data across
multiple disk drives instead of just one disk drive. RAID 0 does
not provide any data redundancy, but does offer the best highspeed data throughput. RAID 0 breaks up data into smaller blocks
and then writes a block to each drive in the array. Disk striping enhances performance because multiple drives are accessed
25
INTRODUCTION
simultaneously; the reliability of RAID Level 0 is less because the
entire array will fail if any one disk drive fails, due to a lack of
redundancy.
1.7.2 RAID 1
RAID 1 is also known as “disk mirroring”; data written to one disk
drive is simultaneously written to another disk drive. Read performance may be enhanced if the array controller can, in parallel,
accesses both members of a mirrored pair. During writes, there
will be a minor performance penalty when compared to writing
to a single disk. If one drive fails, all data (and software applications) are preserved on the other drive. RAID 1 offers extremely
high data reliability, but at the cost of doubling the required data
storage capacity.
26
INTRODUCTION
1.7.3 RAID 1E
RAID 1E is a combination of RAID 0 and RAID 1, combing stripping with disk mirroring. RAID Level 1E combines the fast performance of Level 0 with the data redundancy of Leve1 1. In
this configuration, data is distributed across several disk drives,
similar to Level 0, which are then duplicated to another set of
drive for data protection. RAID 1E has been traditionally implemented using an even number of disks, some hybrids can use an
odd number of disks as well. Illustration is an example of a hybrid RAID 1E array comprised of five disks; A, B, C, D and E. In
this configuration, each strip is mirrored on an adjacent disk with
wrap-around. In fact this scheme - or a slightly modified version
of it - is often referred to as RAID 1E and was originally proposed
by IBM. When the number of disks comprising a RAID 1E is even,
the striping pattern is identical to that of a traditional RAID 1E,
with each disk being mirrored by exactly one other unique disk.
Therefore, all the characteristics for a traditional RAID 1E apply
to a RAID 1E when the latter has an even number of disks. Areca
RAID 1E offers a little more flexibility in choosing the number of
disks that can be used to constitute an array. The number can be
even or odd.
1.7.4 RAID 3
RAID 3 provides disk striping and complete data redundancy
though a dedicated parity drive. RAID 3 breaks up data into
smaller blocks, calculates parity by performing an exclusive-or
on the blocks, and then writes the blocks to all but one drive in
27
INTRODUCTION
the array. The parity data created during the exclusive-or is then
written to the last drive in the array. If a single drive fails, data is
still available by computing the exclusive-or of the contents corresponding strips of the surviving member disk. RAID 3 is best
for applications that require very fast data- transfer rates or long
data blocks.
1.7.5 RAID 5
RAID 5 is sometimes called striping with parity at byte level. In
RAID 5, the parity information is written to all of the drives in the
controllers rather than being concentrated on a dedicated parity
disk. If one drive in the system fails, the parity information can
be used to reconstruct the data from that drive. All drives in the
array system can be used for seek operations at the same time,
greatly increasing the performance of the RAID system. This
relieves the write bottleneck that characterizes RAID 4, and is the
primary reason that RAID 5 is more often implemented in RAID
arrays.
28
INTRODUCTION
1.7.6 RAID 6
RAID 6 provides the highest reliability, but is not yet widely used.
It is similar to RAID 5, but it performs two different parity computations or the same computation on overlapping subsets of
the data. RAID 6 can offer fault tolerance greater than RAID 1 or
RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data. RAID 6 is an extension of RAID 5 but uses a
second, independent distributed parity scheme. Data is striped on
a block level across a set of drives, and then a second set of parity is calculated and written across all of the drives.
Summary of RAID Levels
The SATA RAID controller supports RAID Level 0, 1, 1E, 3, 5 and 6.

Step 5 Connect the SATA cable
Model ARC-11XX and ARC-12XX controllers have dual-layer SATA
internal connectors. If you have not already connected your SATA
cables, use the cables included with your kit to connect the controller to the SATA hard drives.
The cable connectors are all identical, so it does not matter which
end you connect to your controller, SATA hard drive, or cage backplane SATA connector.
Figure 2-13, SATA Cable
Note:
The SATA cable connectors must match your HDD cage.
For example: Channel 1 of RAID Card connects to channel 1
of HDD cage, channel 2 of RAID Card connects to channel 2
of HDD cage, and follow this rule.

HARDWARE INSTALLATION
The intelligent LED controller outputs a low-level pulse to determine if status LEDs are attached to pin sets 1 and 2. This allows
automatic controller configuration of the LED output. If the logical level is different between the fist 2 sets of the HDD LED header
(LED attached to Set 1 but not Set 2), the controller will assign the
first HDD LED header as the global indicator connector. Otherwise,
each LED output will show only individual drive status.
The SATA RAID controller provides four kinds of LED status connectors.
A: Global indicator connector, which lights when any drive is active.
B: Individual LED indicator connector, for each drive channel.
C: I2C connector, for SATA proprietary backplane enclosure.
D: SGPIO connector for SAS Backplane enclosure
The following diagrams and description describes each type of connector.
Note:
A cable for the global indicator comes with your computer
system. Cables for the individual drive LEDs may come with
a drive cage, or you may need to purchase them.
A: Global Indicator Connector
If the system will use only a single global indicator, attach the
global indicator cable to the two pins HDD LED connector. The following diagrams show the connector and pin locations.

D: SGPIO bus
The preferred I/O connector for server backplanes is the Min SAS
4i internal serial-attachment connector. This connector has eight
signal pins to support four SATA drives and six pins for the SGPIO
(Serial General Purpose Input/Output) side-band signals. The
SGPIO bus is used for efficient LED management and for sensing drive Locate status. See SFF 8485 for the specification of the
SGPIO bus.
The number of drives supported can be increased, by a factor of
four, by adding similar backplane to maximum of 24 drives (6
backplanes)
LED Management: The backplane may contain LEDs to indicate
drive status. Light from the LEDs could be transmitted to the outside of the server by using light pipes mounted on the SAS drive
tray. A small EPLP microcontroller on the backplane, connected via
the SGPIO bus to a ARC-1231ML/1261ML/1280ML SATA RAID controller, could control the LEDs. Activity: blinking 5 Times/Second
Fault: solid illuminated
Drive Locate Circuitry: The locate of a drive may be detected by
sensing the voltage level of one of the pre-charge pins before and
after a drive is installed. Fault (red) blinking 2 Times/Second.

work with Areca sideband cable.
The sideband header is located at backplane. For SGPIO to
work properly, please connect Areca 8-pin sideband cable to the
sideband header as shown above. See the table for pin definitions.
Step 7. Re-check the SATA HDD LED and Fault LED Cable
connections
Be sure that the proper failed drive channel information is displayed
by the Fault and HDD Activity LEDs. An improper connection will
tell the user to ‘‘Hot Swap’’ the wrong drive. This will remove the
wrong disk (one that is functioning properly) from the controller.
This can result in failure and loss of system data.
Step 8. Power up the System
Thoroughly check the installation, reinstall the computer cover, and
reconnect the power cord cables. Turn on the power switch at the
rear of the computer (if equipped) and then press the power button
at the front of the host computer.
Step 9. Configure volume set
The SATA RAID controller configures RAID functionality through the
McBIOS RAID manager. Please refer to Chapter 3, McBIOS RAID
manager, for the detail regarding configuration. The RAID controller
can also be configured through the McRAID storage manager software utility with ArcHttp proxy server installed through on-board
Lan port or LCD module. For this option, please reference Chapter
6, Web Browser-Based Configuration or LCD configuration menu.
52
HARDWARE INSTALLATION
Step 10. Install the controller driver
For a new system:
• Driver installation usually takes places as part of operating system installation. Please reference the Chapter 4 Diver Installation
for the detail installation procedure.
In an existing system:
• Install the controller driver into the existing operating system.
Please reference the Chapter 4, Driver Installation, for the detailed
installation procedure.
Note:
Look for newest release versions of drivers please download
from http://www.areca.com.tw
Step 11. Install ArcHttp proxy Server
The SATA RAID controller firmware has embedded the web-browser
RAID manager. ArcHttp proxy driver will enable it. The browserbased RAID manager provides all of the creation, management,
and monitor SATA RAID controller status. Please refer to the
Chapter 5 for the detail ArcHttp proxy server installation. For SNMP
agent function, please refer to Appendix C.
Step 12. Determining the Boot sequences
The SATA RAID controller is a bootable controller. If your system
already contains a bootable device with an installed operating system, you can set up your system to boot a second operating system from the new controller. To add a second bootable controller,
you may need to enter setup and change the device boot sequence
so that the SATA RAID controller heads the list. If the system BIOS
setup does not allow this change, your system may not be configurable to allow the SATA RAID controller to act as a second boot
device.

3.7.1 Quick Volume/RAID Setup
“Quick Volume/RAID Setup” is the fastest way to prepare a RAID
set and volume set. It requires only a few keystrokes to complete. Although disk drives of different capacity may be used in
the RAID set, it will use the capacity of the smallest disk drive as
the capacity of all disk drives in the RAID set. The “Quick Volume/RAID Setup” option creates a RAID set with the following
properties:
1. All of the physical drives are contained in one RAID set.
2. The RAID level, hot spare, capacity, and stripe size options
are selected during the configuration process.
3. When a single volume set is created, it can consume all or a
portion of the available disk capacity in this RAID set.
4. If you need to add an additional volume set, use the main
menu “Create Volume Set” function.
The total number of physical drives in a specific RAID set determine the RAID levels that can be implemented within the RAID

A volume set is seen by the host system as a single logical device; it is organized in a RAID level within the controller utilizing one or more physical disks. RAID level refers to the level of
data performance and protection of a volume set. A volume set
can consume all of the capacity or a portion of the available disk
capacity of a RAID set. Multiple volume sets can exist on a RAID
set. If multiple volume sets reside on a specified RAID set, all
72
BIOS CONFIGURATION
volume sets will reside on all physical disks in the RAID set. Thus
each volume set on the RAID set will have its data spread evenly
across all the disks in the RAID set rather than one volume set
using some of the available disks and another volume set using
other disks.
3.7.3.1 Create Volume Set
1. Volume sets of different RAID levels may coexist on the same
raid set.
2. Up to 16 volume sets in a RAID set can be created by the
SATA RAID controller.
3. The maximum addressable size of a single volume set is not
limited to 2 TB as with other cards that support only 32-bit
mode.
To create a volume set, follow the following steps:
1. Select the “Volume Set Function” from the Main menu.
2. Choose the “Create Volume Set” from “Volume Set Functions”
dialog box screen.

BIOS CONFIGURATION
• Volume Set Migration
Migrating occurs when a volume set is migrating from one RAID
level to another, when a volume set strip size changes, or when
a disk is added to a RAID set. Migration status is displayed in
the volume status area of the “Volume Set Information” screen
when moving from one RAID level to another, when a volume
set strip size changes, or when a disk is added to a RAID set.
3.7.3.4 Check Volume Set
Use this option to verify the correctness of the redundant data in
a volume set. For example, in a system with a dedicated parity
disk drive, a volume set check entails computing the parity of
the data disk drives and comparing those results to the contents
of the dedicated parity disk drive. To check volume set from
“Raid Set System Function”, move the cursor bar to the “Volume
Set Functions” menu and select the “Check Volume Set” item,
then press the Enter key. The “Volume Set Functions” menu
will show all Raid Set number items. Move the cursor bar to an
Raid Set number item and then press the Enter key to show all
Volume Set items. Select the volume set to be checked from the
list and press Enter to select it. After completing the selection,
the confirmation screen appears, presses Yes to start the check.

JBOD is an acronym for “just a Bunch Of Disks”. It represents
a volume set that is created by the concatenation of partitions
on the disk. The operating system can see all disks when the
JBOD option is selected. It is necessary to delete any RAID

The SATA RAID controller can support up to SATA ll, which runs
up to 300MB/s, twice as fast as SATA150. NCQ is a command
protocol in Serial ATA that can only be implemented on native Serial ATA hard drives. It allows multiple commands to be
outstanding within a drive at the same time. Drives that support
NCQ have an internal queue where outstanding commands can

3.7.5.8 Stagger Power On
In a PC system with only one or two drives, the power can supply enough power to spin up both drives simultaneously. But in
systems with more than two drives, the startup current from
spinning up the drives all at once can overload the power supply, causing damage to the power supply, disk drives and other
system components. This damage can be avoided by allowing
the host to stagger the spin-up of the drives. New SATA drives
have support staggered spin-up capabilities to boost reliability.
Staggered spin-up is a very useful feature for managing multiple
disk drives in a storage subsystem. It gives the host the ability to spin up the disk drives sequentially or in groups, allowing
the drives to come ready at the optimum time without straining
the system power supply. Staggering drive spin-up in a multiple
drive environment also avoids the extra cost of a power supply
designed to meet short-term startup power demand as well as
steady state conditions.
92
BIOS CONFIGURATION
Areca has supported the fixed value staggered power up function in its previous version firmware. But from firmware version
1.39 and later, SATA RAID controller has included the option for
customer to select the disk drives sequentially stagger power up
value. The values can be selected from 0.4ms to 6ms per step
which powers up one drive.

3.7.5.10 HDD SMART Status Polling
An external RAID enclosure has the hardware monitor in the
dedicated backplane that can report HDD temperature status
to the controller. However, PCI cards do not use backplanes if
the drives are internal to the main server chassis. The type of
enclosure cannot report the HDD temperature to the controller.
For this reason, HDD SMART Status Polling was added to enable
scanning of the HDD temperature function in the version 1.36
date: 2005-05-19 (and later). It is necessary to enable “HDD
SMART Status Polling” function before SMART information is
accessible. This function is disabled by default.
The following screen shot shows how to change the BIOS setting
to enable the Polling function.

SATA RAID controllers use drive truncation so that drives from
different vendors are more likely to be usable as spares for one
another. Drive truncation slightly decreases the usable capac-

BIOS CONFIGURATION
ity of a drive that is used in redundant units. The controller
provides three truncation modes in the system configuration:
Multiples Of 10G, Multiples Of 1G, and No Truncation.
Multiples Of 10G: If you have 120 GB drives from different
vendors; chances are that the capacity varies slightly. For example, one drive might be 123.5 GB, and the other 120 GB. Areca
drive Truncation mode Multiples Of 10G uses the same capacity for both of these drives so that one could replace the other.
Multiples Of 1G: If you have 123 GB drives from different vendors; chances are that the capacity varies slightly. For example,
one drive might be 123.5 GB, and the other 123.4 GB. Areca
drive Truncation mode Multiples Of 1G uses the same capacity
for both of these drives so that one could replace the other.
No Truncation: It does not truncate the capacity.

3.7.6.1 DHCP Function
DHCP (Dynamic Host Configuration Protocol) allows network administrators centrally manage and automate the assignment of
IP (Internet Protocol) addresses on a computer network. When
using the TCP/IP protocol (Internet protocol), it is necessary for
a computer to have a unique IP address in order to communicate to other computer systems. Without DHCP, the IP address
must be entered manually at each computer system. DHCP lets
a network administrator supervise and distribute IP addresses
from a central point. The purpose of DHCP is to provide the
automatic (dynamic) allocation of IP client configurations for a
specific time period (called a lease period) and to minimize the
work necessary to administer a large IP network. To manually

the “Disabled’ or ‘Enabled” option to enable or disable the DHCP
function. If DHCP is disabled, it will be necessary to manually
enter a static IP address that does not conflict with other devices on the network.
3.7.6.2 Local IP address
If you intend to set up your client computers manually (no
DHCP), make sure that the assigned IP address is in the same
range as the default router address and that it is unique to your
private network. However, it is highly recommend to use DHCP
if that option is available on your network. An IP address allocation scheme will reduce the time it takes to set-up client computers and eliminate the possibilities of administrative errors
and duplicate addresses. To manually configure the IP address
of the controller, move the cursor bar to the Main menu Ethernet
Configuration Function item and then press the Enter key. The
Ethernet Configuration menu appears on the screen. Move the
cursor bar to Local IP Address item, then press the Enter key
to show the default address setting in the SATA RAID controller.
You can then reassign the static IP address of the controller.

4.1 Creating the Driver Diskettes
The CD-ROM disc shipped with the SATA RAID controller is a selfbooting CD. In order to created driver diskettes for Windows,
Linux, FreeBSD or more installation drivers, your system is required to support booting from the CD-ROM.
If you do not have the CD-ROM disc with the package, contact your
local dealer or you can also download the latest version drivers for
Windows 2000/XP/2003, Linux, freeBSD and more from the ARECA
web site at http://www.areca.com.tw
102
DRIVER INSTALLATION
The following steps are required to create the driver diskettes:
1. The computer system BIOS must be set to boot-up from the CDROM.
2. Insert the SATA Controller Driver CD disc into the CD-ROM drive.
3. The system will boot-up from CD-ROM Drive; to create the driver diskettes, select the “SATA RAID controller Driver Diskette
Make Utility”, and a screen with several choices will be displayed.
4. Move the highlight bar to the “Create Driver Disk” entry and
press Enter.

ARCHTTP PROXY SERVER INSTALLATION
5. ArcHttp Proxy Server Installation
Overview
After hardware installation, the SATA disk drives connected to the SATA
RAID controller must be configured and the volume set units initialized
before they are ready to use.
The user interface for these tasks can be accessed through the built-in
configuration and administration utility that resides in the controller’s
firmware. It provides complete control and management of the controller and disk arrays, eliminating the need for additional hardware or
software.
In addition, a software utility to configure the SATA RAID is provided
on the CD-ROM delivered with SATA controller. This CD-ROM contains
the software utility that can monitor, test, and support the SATA RAID
controller. The software utility and McRAID storage manager can configure and monitor the SATA RAID controller via ArcHttp Proxy Server.
The following table outlines their functions:

recovered. The “SIGANT” function can regenerate the signature
for the RAID set.
6.6 Volume Set Functions
A volume set is seen by the host system as a single logical device.
It is organized in a RAID level with one or more physical disks.
RAID level refers to the level of data performance and protection of
a volume set. A volume set capacity can consume all or a portion
of the disk capacity available in a RAID set. Multiple volume sets
can exist on a group of disks in a RAID set. Additional volume sets
created in a specified RAID set will reside on all the physical disks
in the raid set. Thus each volume set on the RAID set will have its
data spread evenly across all the disks in the RAID set.
6.6.1 Create Volume Set
1. Volume sets of different RAID levels may coexist on the same
raid set.
2. Up to 16 volume sets can be created by the SATA RAID controller.
3. The maximum addressable size of a single volume set is not
limited to 2 TB because the controller is capable of 64-bit mode.
However, the operating system itself may not be capable of addressing more than 2 TB. See the Areaca website for details.
To create a volume set on a raid set, move the cursor bar to the
130

• Initialization Mode
Press “Enter” key to define fast initialization or Selected the
Background (Instant Available). When background Initialization,
the initialization proceeds as a background task, the volume set
is fully accessible for system reads and writes. The operating
system can instantly access to the newly created arrays without
requiring a reboot and waiting the initialization complete. when
Fast Initialization, the initialization proceeds must be completed
before the volume set ready for system accesses.
• Strip Size
This parameter sets the size of the stripe written to each disk in
a RAID level 0, 1, 1E, 5 or 6 logical drive. You can set the stripe
size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.
A larger stripe size produces better read performance, especially if your computer does mostly sequential reads. However,
if you are sure that your computer does random reads more
often, select a smaller stripe size.
Note: RAID level 3 can’t modify strip size.
• Cache Mode
The SATA RAID controller supports Write-Through Cache and
Write-Back Cache.
• SCSI Channel/SCSI ID/SCSI Lun
SCSI Channel: The SATA RAID controller function is simulated
as a SCSI RAID controller. The host bus is represented as a
SCSI channel. Choose the SCSI Channel.
SCSI ID: Each SCSI device attached to the SCSI card, as well
as the card itself, must be assigned a unique SCSI ID number.
A SCSI channel can connect up to 15 devices. The SATA RAID
controller is a large SCSI device. Assign an ID from a list of
SCSI IDs.

6.8.1 System Config
To set the raid system function, move the cursor to the main
menu and click the “Raid System Function” link. The “Raid System
Function” menu will show all items, then select the desired function.
• System Beeper Setting
The Alert Beeper function item is used to Disabled or Enable the
SATA RAID controller alarm tone generator.
• Background Task Priority
The Raid Rebuild Priority is a relative indication of how much
time the controller devotes to a rebuild operation. The SATA
RAID controller allows the user to choose the rebuild priority
(ultraLow, Low, Normal, High) to balance volume set access
and rebuild tasks appropriately. For high array performance,
specify a Low value.
• JBOD/RAID Configuration
JBOD is an acronym for “Just a Bunch Of Disks”. It represents a volume set that is created by the concatenation of partitions on the disk. The OS can see all disks when this option is
selected. It is necessary to delete a RAID set if the disks in that
set are to be convereted to JBOD mode.
• Maximun SATA Supported
The SATA RAID controller can support up to SATA ll, which runs
up to 300MB/s. NCQ is a command protocol in Serial ATA that
can only be implemented on native Serial ATA hard drives. It
allows multiple commands to be outstanding within a drive at
the same time. Drives that support NCQ have an internal queue
where outstanding commands can be dynamically rescheduled
or re-ordered, along with the necessary tracking mechanisms
for outstanding and completed portions of the workload. The
RAID subsystem allows user to choose the SATA Mode (slowest
to fastest): SATA150, SATA150+NCQ, SATA300, SATA300+NCQ.
• HDD Read Ahead Cache
138
WEB BROWSER-BASED CONFIGURATION
Allow Read Ahead (Default: Enabled)—When Enabled, the drive’
s read ahead cache algorithm is used, providing maximum
performance under most circumstances.
• Stagger Power on
In a PC system with only one or two drives, the power can
supply enough power to spin up both drives simultaneously. But
in systems with more than two drives, the startup current from
spinning up the drives all at once can overload the power supply,
causing damage to the power supply, disk drives and other
system components. This damage can be avoided by allowing
the host to stagger the spin-up of the drives. New SATA drives
have support staggered spin-up capabilities to boost reliability.
Staggered spin-up is a very useful feature for managing multiple
disk drives in a storage subsystem. It gives the host the ability
to spin up the disk drives sequentially or in groups, allowing
the drives to come ready at the optimum time without straining
the system power supply. Staggering drive spin-up in a multiple
drive environment also avoids the extra cost of a power supply
designed to meet short-term startup power demand as well as
steady state conditions.
Areca has supported the fixed value staggered power up function
in its previous version firmware. But from firmware version
1.39 and later, SATA RAID controller has included the option for
customer to select the disk drives sequentially stagger power up
value. The values can be selected from 0.4ms to 6ms per step
which powers up one drive.
139
WEB BROWSER-BASED CONFIGURATION
• Empty HDD Slot LED
From firmware version 1.39 date: 04/01/2006 and later, the
firmware has added the "Empty HDD Slot LED" option to setup
the Failed LED light "ON "or "OFF". When each slot has a power
LED for the HDD installed identify, user can set this option to
"OFF". Choose this option "ON", the failed LED light will flash
red light; if no HDD installed.
• HDD SMART Status Polling
An external RAID enclosure has the hardware monitor in the
dedicated backplane that can report HDD temperature status
to the controller. However, PCI type controllers do not use
backplanes if the drives are internal to the main server chassis.
The type of enclosure cannot report the HDD temperature to
the controller. For this reason, HDD SMART Status Polling was
added to enable scanning of the HDD temperature function in
the version 1.36 date: 2005-05-19 (and later). It is necessary
to enable “HDD SMART Status Polling” function before SMART
information is accessible. This function is disabled by default.
The following screen shot shows how to change the BIOS setting
to enable the Polling function.

WEB BROWSER-BASED CONFIGURATION
• Disk Write Cache Mode
A user can set the “Disk Write Cache Mode” to: Auto, Enabled,
or Disabled.
• Disk Capacity Truncation Mode
SATA RAID controllers use drive truncation so that drives from
differing vendors are more likely to be able to be used as spares
for each other. Drive truncation slightly decreases the usable
capacity of a drive that is used in redundant units.
The controller provides three truncation modes in the system
configuration: Multiples Of 10G, Multiples Of 1G, and No
Truncation.
Multiples Of 10G: If you have 120 GB drives from different
vendors; chances are that the capacity varies slightly. For exam-
141
WEB BROWSER-BASED CONFIGURATION
ple, one drive might be 123.5 GB, and the other 120 GB. Areca
drive Truncation mode Multiples Of 10G uses the same capacity for both of these drives so that one could replace the other.
Multiples Of 1G: If you have 123 GB drives from different vendors; chances are that the capacity varies slightly. For example,
one drive might be 123.5 GB, and the other 123.4 GB. Areca
drive Truncation mode Multiples Of 1G uses the same capacity
for both of these drives so that one could replace the other.
No Truncation: It does not truncate the capacity.
6.8.2 Ethernet Configuration (12/16/24-port)
Use this feature to set the controller Ethernet port configuration.
A customer doesn’t need to create a reserved space on the arrays
before the Ethernet port and HTTP service are working. The firmware-embedded Web Browser-based RAID manager can access
it from any standard internet browser or from any host computer
either directly connected or via a LAN or WAN with no software or
patches required.
DHCP (Dynamic Host Configuration Protocol) is a protocol that
lets network administrators manage centrally and automate the
assignment of IP (Internet Protocol) configurations on a computer
network. When using the Internet’s set of protocols (TCP/IP), in
order for a computer system to communicate to another computer system, it needs a unique IP address. Without DHCP, the
IP address must be entered manually at each computer system.
142
WEB BROWSER-BASED CONFIGURATION
DHCP lets a network administrator supervise and distribute IP
addresses from a central point. The purpose of DHCP is to provide
the automatic (dynamic) allocation of IP client configurations for
a specific time period (called a lease period) and to eliminate the
work necessary to administer a large IP network.

source, such as a radio or satellite receiver or modem. It provides
accuracies typically within a millisecond on LANs and up to a few
tens of milliseconds on WANs relative to Coordinated Universal
Time (UTC) via a Global Positioning Service (GPS) receiver, for
example:
• NTP Sever Address
The most important factor in providing accurate, reliable time is
the selection of NTP servers to be used in the configuration file.
Typical NTP configurations utilize multiple redundant servers and
diverse network paths in order to achieve high accuracy and reliability. Our NTP configuration supports two existing public NTP
synchronization subnets.

APPENDIX
Appendix C
SNMP Operation & Definition
Overview
The McRAID manager includes a firmware-embedded Simple Network Management Protocol (SNMP) agent and SNMP Extension
Agent for the SATA RAID controller. An SNMP-based management
application (also known as an SNMP manager) can monitor the disk
array. An example of An SNMP management application is HewlettPackard’s Open View. The SNMP Extension Agent can be used to
augment the SATA RAID controller if you are already running an
SNMP management application at your site.
SNMP Definition
SNMP, an IP-based protocol, has a set of commands for getting the
status of target devices. The SNMP management platform is called
the SNMP manager, and the managed devices have the SNMP
agent loaded. Management data is organized in a hierarchical data
structure called the management Information Base (MIB). These
MIBs are defined and sanctioned by various industry associations. The objective is for all vendors to create products in compliance with these MIBs so that inter-vendor interoperability can be
achieved. If a vendor wishes to include additional device information that is not specified in a standard MIB, then that is usually
done through MIB extensions.
159
APPENDIX
MIB Compilation and Definition File creation
Before the manager application accesses the SATA RAID controller,
it is necessary to integrate the MIB into the management application’s database of events and status indicator codes. This process
is known as compiling the MIB into the application. This process
is highly vendor-specific and should be well-covered in the User’s
Guide of your SNMP application. Ensure the compilation process
successfully integrates the contents of the ARECARAID.MIB file into
the traps database.
SNMP Installation
The installation of the SNMP manager is accomplished in several
phases:
• Starting the Firmware-embedded SNMP community configuration.
• Installing the SNMP Extension Agent on the server
• Installing the SNMP Manager software on the client
• Placing a copy of the management information base (MIB) in a
directory which is accessible to the management application
• Compiling the MIB description file with the management appli
cation
160
APPENDIX
Starting the SNMP function setting
• Community Name
Community name acts as a password to screen accesses to the
SNMP agent of a particular network device. Type in the community
names of the SNMP agent. Before access is granted to a request
station, this station must incorporate a valid community name into
its request; otherwise, the SNMP agent will deny access to the
system.
Most network devices use “public” as default of their community
names. This value is case-sensitive.
SNMP Extension Agent Installation for Windows
You must have administrative level permission to install SATA RAID
software. This procedure assumes that the SATA RAID hardware
and Windows are both installed and operational in your system.
To enable the SNMP agent for Windows, configure Windows for
TCP/IP and SNMP services. The ARECA SNMP Extension Agent file
is ARCSNMP.DLL.
Screen captures in this section are taken from a Windows XP installation. If you are running another version of Windows, your screens
may look different, but the ARECA SNMP Extension Agent installation is essentially the same.
1. Insert the SATA RAID controller CD in the CD-ROM drive.
2. Run the setup.exe file that resides at: <CD-ROM>\packages\
161
APPENDIX
windows\http\setup.exe on the CD-ROM. (If SNMP service was
not installed, please install SNMP service first.)

General Troubleshooting Tips
Most of controller errors are traceable to external factors, such as
conflicts with other installed cards, motherboard incompatibility,
bad or incorrectly configured drives, loose cables, improper controller installation, or other installation errors.
To troubleshoot SATA RAID controller problems, try simplifying your
hardware configuration by removing some other devices from the
system and then adding them back one at a time.
Look for the latest information on SATA RAID Controllers as well
as the newest drivers on the ARECA web site at http://www.areca.
com.tw. The following general guidelines are for some specific error conditions:
Q1: The BIOS Message of the SATA RAID controller never
appears on the screen
Answer:
(1). Ensure the controller is inserted correctly into the PCI slot.
(2). Ensure 3.3 volts are being supplied to the PCI slot.
(3). Check the cabling between the SATA drives or enclosure the
SATA RAID controller.
Q2: How many SATA RAID controllers can be installed into a
computer system?
Answer:
Up to 4 RAID controllers in a system are supported.
Q3: The boot device cannot found
Answer:
Enter the system BIOS setup utility Per manufacture directions and
configure it so that the RAID card volume set is once again selected as the primary boot device (or first in the boot device list)
169
APPENDIX
Q4: What PCI slots are supported by the SATA RAID
controllers?
Answer:
For all PCI-X SATA RAID controllers, install card in a 64-bit/133MHz
PCI-X for the best performance. It also can be used in 64-bit / 66
MHz slots, 32-bit/66MHz PCI slots as well as 32-bit/33MHz slots.
All PCI-X SATA RAID controllers can not work with 5V PCI slot.
PCI-Express SATA RAID controllers require an x8 or x16 slots. The
card can function in x4 or x1 signal slots if those slots are open at
the end to accept larger x8 cards, but performance will be reduced
in these slower slots.
Check the Areca FAQ website for motherboard a compatibility list.
Q5: What is the difference between RAID 6 and RAID 5?
Answer:
RAID 6 allows two drives to fail simultaneously without downtime
or data loss. However, RAID 5 only allows one drive to fail. RAID 6
thus provides a much higher level of fault tolerance than RAID 5. It
is a perfect solution when data is mission-critical.
Due to this higher level of protection, users can set up larger RAID
volumes, spanning up to 56 physical drives. With the ARECA RAID
6 engine, RAID 6 and RAID 5 have similar performance in the SATA
RAID controller.
Q6: What products support RAID 6?
Answer:
RAID 6 is available on controller models with the RAID 6 engine
installed.
Q7: What operating systems are supported?
Answer:
The SATA RAID controllers support Microsoft® Windows® Server
2003, Windows XP, Windows 2000, Red Hat Linux, SuSE Linux, and
FreeBSD. For specific OS versions, see http://www.areca.com.
tw for more information.

APPENDIX
Q8: Will ARECA submit the Linux code to kernel.org?
Answer:
Yes. ARECA Serial ATA ll RAID the lastest driver has been integrated
directly into the Linux kernel 2.6.17-rc3-mm1 (and later), allowing
future versions of Linux operating systems to support Areca’s entire
fam-ily PCI-X and PCI-Express series of high performance SATA ll
RAID controllers.
Q9: What is the warranty period?
Answer:
Like all ARECA External RAID controllers, the PCI-X or PCI-Express
SATA RAID controller is backed by a 3-year warranty.
Q10: Which O/S (Operating System) will support X86 64-bit
processors?
Answer:
The following O/S vendors have announced product support for
AMD64 and Intel EM64T. Contact each vendor for more details. The
following is our currently supported OS and version for 64-bit processor. We will support others shortly after other versions release.
Microsoft:
Production support will be available in:
• Windows XP Professional x64 Edition
• Windows Server 2003 64-Bit Edition
Red Hat:
Production support will be available in:
• Red Hat Enterprise Linux 3 update 2
SuSE:
Production support will be available in:
• SLES9
FreeBSD:
Production support will be available in:
• FreeBSD 5.3
171
APPENDIX
Q11: Is it possible to write software that will run on Intel’s
processors with Intel® EM64T, and AMD’s 64-bit capable
processors?
Answer:
Yes, in most cases. Even though the hardware microarchitecture
for each company’s processor is different, the operating system
and software ported to one processor will likely run on the other
processor due to the close similarity of the instruction set architectures. However, Intel processors support additional features, like
the SSE3 instructions and Hyper-Threading Technology, which are
not supported on non-Intel platforms. As such, we believe developers will achieve maximum performance and stability by designing specifically for Intel architectures and by taking advantage of
Intel’s breadth of software tools and enabling services.
Q12: How will Intel® EM64T work and what software is
there to take advantage of 64-bit extensions?
Answer:
Platforms with Intel® EM64T/AMD64 can be run in three basic
ways (note: a 64-bit capable BIOS is required for all three scenarios):
1. 32-bit O/S and 32-bit applications (Legacy Mode): No software
changes are required, however the user gets no benefit from
Intel® EM64T or AMD64.
2. 64-bit O/S and 32-bit applications (Compatibility Mode): This
usage requires all 64-bit device drivers. In this mode, the O/S
will see the 64-bit extensions, but the 32-bit application will
not. Existing 32-bit applications do not need to be recompiled,
and may or may not benefit from the 64-bit extensions. The
application will likely need to be recertified by the vendor to
run on the new 64-bit extended O/S.
3. 64-bit O/S and 64-bit applications (64-bit Mode): This usage
requires 64-bit device drivers. It also requires applications to
be modified for 64-bit operation and then recompiled and validated.

GLOSSARY
Glossary
2TB
The 32-bit file systems have a maximum limitation of 2 TB per volume
set. 64-bit versions remove this limitation. so, if you are building large
warehouses, you should consider 64-bit versions.
Array
An array is a logical disk comprised of multiple physical hard disks.
The number of hard disks in an array is dictated by the type of the
array and the number of spares that may be assigned to it. (Arrays
are also sometimes referred to as containers). Furthermore, whether
an array can be built using part of the space on a disk (as opposed to
being forced to use the whole disk) depends upon the implementation.
Arrays are typically used to provide data redundancy and/or enhanced
I/O performance.
ATA
Acronym for “AT Bus Attachment” - a standard interface to IDE hard
disks. Western Digital’s IDE disk interface was standardized by ANSI to
form the ATA specification using a 16-bit ISA bus.
Auto Reassign Sector
SATA drives perform automatic defect re-assignment for both read and
write errors. Writes are always completed - if a location to be written is found to be defective, the drive will automatically relocate that
write command to a new location and map out the defective location.
If there is a recoverable read error, the correct data will be transferred
to the host and that location will be tested by the drive to be certain
the location is not defective - if it is found to have a defect, it will be
automatically relocated to a new location and the defective location
mapped out. In the event of an unrecoverable read error, the error will
be reported to the host and the location flagged as potentially defective. A subsequent write to that location will initiate a sector test and
relocation should that location have a defect.
174
GLOSSARY
Battery Backup Module
Many modern RAID controllers are armed with a battery backup Module (BBM). While an UPS protects most servers from power fluctuations or failures, a BBM provides an additional level of protection. In
the event of a power failure, a BBM supplies power to retain data in
the RAID controller’s cache, thereby permitting any potentially dirty
data in the cache to be flushed out to secondary storage when power
is restored.
BIOS
(Basic Input/Output System) software is stored on a chip and provides
an interface between the operating system and the hardware. Usually
the BIOS is built into a ROM chip installed on the motherboard so that
the BIOS will always available and not affected by disk failure.
Cache
Controller memory used to speed up data transfer to and from a disk.
Consistency Check
In RAID, check consistency verifies the correctness of redundant data
in an array. For example, in a system with dedicated parity, checking
consistency means computing the parity of the data drives and comparing the results to the contents of the dedicated parity drive.
Driver
It is a piece of software – that is often executed in kernel mode – that
controls a hardware device. Typically drivers provide an interface by
which applications can use the device in a uniform and hardware-independent manner.
Hot Spare
An extra physical disk drive in a RAID configuration that controller can
use to automatically rebuild a system drive when another drive fails.
The hot spare drive must have at least as mush capacity as the largest
disk drive in the array or the rebuild may not start.
175
GLOSSARY
Hot Spare
An extra physical disk drive in a RAID configuration that a controller
can use to automatically rebuild a system drive when another drive
fails. The hot spare drive must have at least as mush capacity as the
largest disk drive in the array or the rebuild will not start.
Hardware RAID versus Software RAID
Beyond the different types of RAID, there are two implementation
forms: hardware-based and software-based. Hardware-based RAID
is obviously implemented at a physical level, whereas software-based
RAID is done using the operating system. It is always optimal to have
RAID done at a physical (hardware) level.
Hot Swap
To pull out a component from a system and plug in a new one while
the power is still on and the unit is still operating.
NVRAM
(Non-Volatile Random Access Memory) A memory unit is equipped with
a battery so that the data remain even after the main power had been
switched off. Actually an EEPROM used to store configuration information.
Parity
A technique used to protect a system from data loss due to faults.
When parity is implemented (RAID3 and RAID5), data written is logically XOR’d together to calculate parity, which is stored on the drives
along with the data. In a system with three drives, the data is written
to two drives and the calculated parity is stored on a third drive. If one
drive fails, data on the failed drive is reconstructed from other data
and parity.
PCI Express
An advanced version of the PCI bus introduced in 2002. Rather than
the shared, parallel bus structure of PCI, PCI Express provides a high-
176
GLOSSARY
speed, switched architecture. Each PCI Express link is a serial communications channel made up of two differential wire pairs that provide
2.5 Gbits/sec in each direction. Up to 32 channels may be combined,
creating a parallel interface of independently controlled serial links.
PCI-X
(PCI extended) an enhanced PCI bus technology is backward compatible with existing PCI cards. PCI and PCI-X slots are physically the
same. PCI cards run in PCI-X slots, and PCI-X cards run in PCI slots at
the slower PCI rates. First introduced in 1999, PCI-X offered increased
speed over PCI and has steadily increased to more than 30 times that
of the original PCI bus.
RAID
(Redundant Array of Independent Disks) a disk subsystem that is used
to increase performance or provide fault tolerance. RAID can also be
set up to provide both functions at the same time. RAID is a set of
two or more ordinary hard disks and a specialized disk controller that
contains the RAID functionality. RAID has been developed initially for
servers and stand-alone disk storage systems. RAID is important especially when rebuilding data after a disk failure.
Rebuild
When a RAID array enters into a degraded mode, it is advisable to
rebuild the array and return it to its original configuration (in terms of
the number and state of working disks) to ensure against operation in
degraded mode.
SATA (Serial ATA)
The evolution of the ATA (IDE) interface that changes the physical
architecture from parallel to serial and from master-slave to pointto-point. Unlike parallel ATA interfaces that connect two drives; one
configured as master, the other as slave, each Serial ATA drive is connected to its own interface. At initial introduction, Serial ATA (SATA)
increases the transfer rate to 150 MB/sec (1.5Gb/s) and SATA2 to 300
MB/sec.
177
GLOSSARY
SMART
This technology provides users with advanced warning of Disk Drive
failures, thus enabling the Operating System to warn Users of potential
failure. S.M.A.R.T. was included in EIDE drives with the ATA-3 and later
specification.
SNMP
Since it was developed in 1988, the Simple Network Management
Protocol has become the de facto standard for inter-network management. Because it is a simple solution, requiring little code to implement, vendors can easily build SNMP agents into their products. SNMP
is extensible, allowing vendors to easily add network management
functions to their existing products. SNMP also separates the management architecture from the architecture of the hardware devices,
which broadens the base of multi-vendor support.
Volume Set
A volume set is a concatenation of storage elements that may be RAID
arrays, JBODs, or simply areas of disks that are not part of RAID arrays.
Write-back
When a cache is operating in write-back mode, data written into the
cache is not immediately written out to its destination in secondary storage unless the heuristics governing the flushing of dirty data
demands otherwise. This methodology can improve the efficiency of
write operations under favorable circumstances. However, its use can
potentially lead to incoherences in a system that is not protected from
power fluctuations or other failures.
Write-through
When a cache is operating in write-through mode, data written into
the cache is also written to the destination secondary storage devices.
Essentially write completion does not occur until the data is written to
secondary storage. Thus the contents of the cache and the secondary
storage are always consistent. The advantage is that the possibility
178
GLOSSARY
of data corruption is greatly reduced. The disadvantage is that writethrough operations are more time consuming.
XOR-Engine
All RAID arrays (with the exception of RAID 0, RAID 1 and RAID 1E)
require parity to be calculated and written to the array in conjunction
with data. Typically the parity is a simple XOR on the bytes comprising a stripe. This is a computationally intensive operation that many
modern RAID controllers perform using a dedicated ASIC (instead of
calculating them in firmware on the main embedded processor’s core).
This dedicated ASIC is often referred to as a XOR-engine.
