Introduction
1.2 RAID Concepts
RAID Fundamentals
The basic idea of RAID (Redundant Array of Independent Disks) is to combine
multiple inexpensive disk drives into an array of disk drives to obtain performance,
capacity and reliability that exceeds that of a single large drive. The array of
drives appears to the host computer as a single logical drive.
Five types of array architectures, RAID 1 through RAID 6, were originally defined,
each provides disk fault-tolerance with different compromises in features and
performance. In addition to these five redundant array architectures, it has become
popular to refer to a non-redundant array of disk drives as a RAID 0 array.
Disk Striping
Fundamental to RAID technology is striping. This is a method of combining
multiple drives into one logical storage unit. Striping partitions the storage
space of each drive into stripes, which can be as small as one sector (512
bytes) or as large as several megabytes. These stripes are then interleaved in
a rotating sequence, so that the combined space is composed alternately of
stripes from each drive. The specific type of operating environment determines
whether large or small stripes should be used.
Most operating systems today support concurrent disk I/O operations across
multiple drives. However, in order to maximize throughput for the disk subsystem,
the I/O load must be balanced across all the drives so that each drive can be kept
busy as much as possible. In a multiple drive system without striping, the disk I/O
load is never perfectly balanced. Some drives will contain data files that are
frequently accessed and some drives will rarely be accessed.
Introduction
1-3
By striping the drives in the array with stripes large enough so that each record
falls entirely within one stripe, most records can be evenly distributed across all
drives. This keeps all drives in the array busy during heavy load situations. This
situation allows all drives to work concurrently on different I/O operations, and
thus maximize the number of simultaneous I/O operations that can be performed
by the array.
Definition of RAID Levels
RAID 0 is typically defined as a group of striped disk drives without parity or data
redundancy. RAID 0 arrays can be configured with large stripes for multi-user
environments or small stripes for single-user systems that access long sequential
records. RAID 0 arrays deliver the best data storage efficiency and performance
of any array type. The disadvantage is that if one drive in a RAID 0 array fails, the
entire array fails.
1-4
Introduction
RAID 1, also known as disk mirroring, is simply a pair of disk drives that store
duplicate data but appear to the computer as a single drive. Although striping is
not used within a single mirrored drive pair, multiple RAID 1 arrays can be striped
together to create a single large array consisting of pairs of mirrored drives. All
writes must go to both drives of a mirrored pair so that the information on the
drives is kept identical. However, each individual drive can perform simultaneous,
independent read operations. Mirroring thus doubles the read performance of a
single non-mirrored drive and while the write performance is unchanged. RAID 1
delivers the best performance of any redundant array type. In addition, there is
less performance degradation during drive failure than in RAID 5 arrays.
Introduction
1-5
RAID 3 sector-stripes data across groups of drives, but one drive in the group is
dedicated to storing parity information. RAID 3 relies on the embedded ECC in
each sector for error detection. In the case of drive failure, data recovery is
accomplished by calculating the exclusive OR (XOR) of the information recorded
on the remaining drives. Records typically span all drives, which optimizes the
disk transfer rate. Because each I/O request accesses every drive in the array,
RAID 3 arrays can satisfy only one I/O request at a time. RAID 3 delivers the best
performance for single-user, single-tasking environments with long records.
Synchronized-spindle drives are required for RAID 3 arrays in order to avoid
performance degradation with short records. RAID 5 arrays with small stripes can
yield similar performance to RAID 3 arrays.
Under RAID 5 parity information is distributed across all the drives. Since there
is no dedicated parity drive, all drives contain data and read operations can be
overlapped on every drive in the array. Write operations will typically access one
data drive and one parity drive. However, because different records store their
parity on different drives, write operations can usually be overlapped.
1-6
Introduction
RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity
information to the physical drives in the array. With RAID 6, however, two sets of
parity data are used. These two sets are different, and each set occupies a capacity
equivalent to that of one of the constituent drives. The main advantages of RAID 6
is High data availability – any two drives can fail without loss of critical data.
Introduction
1-7
Dual-level RAID achieves a balance between the increased data availability
inherent in RAID 1 and RAID 5 and the increased read performance inherent in
disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1 or
RAID 10 and RAID 0+5 or RAID 50.
In summary:
RAID 0 is the fastest and most efficient array type but offers no faulttolerance. RAID 0 requires a minimum of two drives.
RAID 1 is the best choice for performance-critical, fault-tolerant
environments. RAID 1 is the only choice for fault-tolerance if no more than
two drives are used.
RAID 3 can be used to speed up data transfer and provide fault-tolerance
in single-user environments that access long sequential records. However,
RAID 3 does not allow overlapping of multiple I/O operations and requires
synchronized-spindle drives to avoid performance degradation with short
records. RAID 5 with a small stripe size offers similar performance.
RAID 5 combines efficient, fault-tolerant data storage with good performance
characteristics. However, write performance and performance during drive
failure is slower than with RAID 1. Rebuild operations also require more
time than with RAID 1 because parity information is also reconstructed. At
least three drives are required for RAID 5 arrays.
RAID 6 is essentially an extension of RAID level 5 which allows for
additional fault tolerance by using a second independent distributed parity scheme (two-dimensional parity). Data is striped on a block level
across a set of drives, just like in RAID 5, and a second set of parity is
calculated and written across all the drives; RAID 6 provides for an extremely high data fault tolerance and can sustain multiple simultaneous
drive failures. Perfect solution for mission critical applications.

1.3 Array Definition
1.3.1 RAID Set
A RAID Set is a group of disks containing one or more volume sets. It is
impossible to have multiple RAID Sets on the same disks.
A Volume Set must be created either on an existing RAID set or on a group of
available individual disks (disks that are not yet a part of an raid set). If there
are pre-existing raid sets with available capacity and enough disks for specified RAID level desired, then the volume set will be created in the existing raid
set of the user’s choice. If physical disks of different capacity 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
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. Volume Sets of different RAID levels may coexist on the same RAID Set.
In the illustration below, Volume 1 can be assigned a RAID 5 level of operation
while Volume 0 might be assigned a RAID 0+1 level of operation.
1-10
Introduction
1.3.3 Easy of Use features
1.3.3.1 Instant Availability/Background Initialization
RAID 0 and RAID 1 volume set can be used immediately after the creation. But
the RAID 3, 5 and 6 volume sets must be initialized to generate the parity. In
the Normal 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. Furthermore, the RAID volume set is
also protected against a single disk failure while initialing. In Fast Initialization,
the initialization proceeds must be completed before the volume set ready for
system accesses.
1.3.3.2 Array Roaming
The RAID subsystem stores configuration information both in NVRAM and on
the disk drives It can protect the configuration settings in the case of a disk
drive or controller failure. Array roaming allows the administrators the ability to
move a completely raid set to another system without losing RAID configuration and data on that raid set. If a server fails to work, the raid set disk drives
can be moved to another server and inserted in any order.
Introduction
1-11
1.3.3.3 Online Capacity Expansion
Online Capacity Expansion makes it possible to add one or more physical
drive to a volume set, while the server is in operation, eliminating the need to
store and restore after reconfiguring the raid set. When disks are added to a
raid set, unused capacity is added to the end of the raid set. Data on the
existing volume sets residing on that 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 create additional volume set. The expansion
process is illustrated as following figure.
The RAID subsystem controller redistributes the original volume set over the
original and newly added disks, using the same fault-tolerance 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.
1-12
Introduction
1.3.3.4 Online RAID Level and Stripe Size Migration
User 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
in the event that additional physical disks are added to the RAID subsystem.
For example, in a system using two drives in RAID level 1, you could add
capacity and retain fault tolerance by adding one drive. With the addition of
third disk, you have the option of adding this disk to your existing RAID logical
drive and migrating from RAID level 1 to 5. The result would be parity fault
tolerance and double the available capacity without taking the system off.
1.3.4 High availability
1.3.4.1 Creating Hot Spares
A hot spare drive is an unused online available drive, which is ready for replacing the failure disk drive. In a RAID level 1, 0+1, 3, 5 or 6 raid set, any
unused online available drive installed but not belonging to a raid set can
define as a hot spare drive. Hot spares permit you to replace failed drives
without powering down the system. When RAID subsystem detects a UDMA
drive failure, the system will automatic and transparent rebuilds using hot
spare drives. The raid set will be reconfigured and rebuilt in the background,
while the RAID subsystem continues to handle system request. During the automatic rebuild process, system activity will continue as normal, however, the
system performance and fault tolerance will be affected.
!
Important:
The hot spare must have at least the same or more capacity as the
drive it replaces.
Introduction
1-13
1.3.4.2 Hot-Swap Disk Drive Support
The RAID subsystem has built the protection circuit to support the replacement
of UDMA hard disk drives without having to shut down or reboot the system.
The 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 subsystems. We provide this feature for subsystems to provide the advanced fault tolerant RAID protection and “online” drive replacement.
1.3.4.3 Hot-Swap Disk Rebuild
A Hot-Swap function can be used to rebuild disk drives in arrays with data
redundancy such as RAID level 1(0+1), 3, 5 and 6. 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 rebuilt. If a hot spare is available, the
rebuild starts automatically when a drive fails. The RAID subsystem automatically and transparently rebuilds failed drives in the background with user-definable rebuild rates. The RAID subsystem will automatically restart the system
and the rebuild if the system is shut down or powered off abnormally during a
reconstruction procedure condition. When a disk is Hot Swap, 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.

3.7 Volume Set Function
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.
3.7.1 Create Volume Set
The following is the volume set features:
1.Volume sets of different RAID levels may coexist on the same raid set.
2.Up to 64 volume sets in a raid set can be created by the RAID subsystem
controller.
To create volume set from raid set system, move the cursor bar to the main
menu and click on the Create Volume Set link. The Select The Raid Set
To Create On It screen will show all raid set number. Tick on a raid set
number that you want to create and then click on the Submit button.
The new create volume set allows user to select the Volume name, capacity,
RAID level, strip size, SCSI ID/LUN, Cache mode, tag queuing and Max Sync
Rate.

For Windows: the max. size 16TB , just use with “ basic disk manager “ under
OS Window 2000, 2003 or XP. Noted that can’t be used by with dynamic disk
manager.
Initialization Mode:
Set the Initialization Mode for the Volume Set. Foreground mode is faster
completion and background is instant available.
Strip Size:
This parameter sets the size of the stripe written to each disk in a RAID 0, 1,
0+1, or 5 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 small stripe size
Note: RAID level 3 can’t modify strip size.
Cache Mode:
The RAID subsystem supports Write-Through Cache and Write-Back Cache.
Tag Queuing:
The Enabled option is useful for enhancing overall system performance under
multi-tasking operating systems. The Command Tag (Drive Channel) function controls the SCSI command tag queuing support for each drive channel. This function
should normally remain enabled. Disable this function only when using older SCSI
drives that do not support command tag queuing
Max SCSI Speed:
The RAID subsystem supports 320 MB/sec as the highest data transfer rate.
SCSI Channel/SCSI ID/SCSI Lun:
SCSI Channel: The RAID subsystem supports one SCSI Channel or Dual
SCSI Channel.
RAID Configuring

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 Wide SCSI channel can
connect up to 15 devices. The RAID subsystem is as a large SCSI device.
We should assign an ID from a list of SCSI IDs.
SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most SCSI host adapter
treats each LUN like a SCSI disk.

JBOD/RAID Configuration
The RAID subsystem supports JBOD and RAID configuration.
Maximum SATA Mode Supported:
The 16 SATA drive channel 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. RAID subsystem allows user to choose the SATA Mode: SATA150,
SAT150+NCQ, SAT300, SATA300+NCQ.

The RAID subsystem supports auto, enabled and disabled. When the RAID subsystem with BBM (battery backup module) the auto option will Enable disk write
cache. Contrariwise, the auto option will Disable disk write cache.
Disk Capacity Truncation Mode:
This RAID subsystem 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.
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. This 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. This drive Truncation mode Multiples Of 1G

3.12 Upgrading the Firmware
Upgrading Flash Firmware Programming Utility
Since the RAID subsystem controller features flash firmware, it is not necessary to change the hardware flash chip in order to upgrade the RAID
firmware. The user can simply re-program the old firmware through the
RS-232 port. New releases of the firmware are available in the form of a
DOS file at OEM’s FTP. The file available at the FTP site is usually a
self-extracting file that contains the following:
XXXXVVV.BIN Firmware Binary (where “XXXX” refers to the model name and
“VVV” refers to the firmware version)
README.TXT It contains the history information of the firmware change. Read
this file first before upgrading the firmware.
These files must be extracted from the compressed file and copied to one
directory in drive A or C.
Establishing the Connection for the RS-232
The firmware can be downloaded to the RAID subsystem controller by using
an ANSI/VT-100 compatible terminal emulation program or Remote web
browser management. You must complete the appropriate installation procedure before proceeding with this firmware upgrade. Whichever terminal
emulation program is used must support the ZMODEM file transfer
protocol.
Configuration of the internal RAID subsystem web browser-based remote RAID
management. Web browser-based RAID management can be used to update the firmware. You must complete the appropriate installation procedure before proceeding with this firmware upgrade.
