This chapter introduces the features and capabilities of
ACS-76200.
You will find:
Ö A full introduction to your ACS-76200 RAID box
Ö Details of key features
Ö A checklist of package contents
Ö A checklist of what else you need to start installation
Ö
Ö An overview of the RAID box and its features, including
connectors, LEDs and jumpers
Overview
Congratulations on your selection of the ACS-76200. The ACS-76200 is a
high-performance and extremely flexible RAID (Redundant Array of
Independent/Inexpensive Disks) controller. RAID is a storage technology used to
improve the processing capabilities of a storage system, providing a combination of
reliability and performance.
The ACS-76200 is the ultimate approach to a flexible RAID solution. It can manage
four different RAID levels (2 bays R0, 3 baysR0, 1+Backup or Spare and R5), with
three SATA disks in a single RAID group. With a cost-effective SATA approach,
supporting Ultra DMA mode, the ACS-76200 strips data to three disk drives
simultaneously, and delivers optimized performance, comparable to more costly SCSI
based solutions.
Featuring intelligent online recovery, the ACS-76200 lets you hot swap a failed drive:
data will automatically be rebuilt to the new drive without any system down time. If
RAID 1 or RAID 5 array exists and one SATA disk drive fails, data is secured by the
other drives, and an alarm sounds to alert you. RAID 5 rebuild will proceed
automatically (during power on) as soon as you lock the disk carrier. If a RAID 0 array
fails, there is no way to recover the data of the RAID system. You should proceed by
reconfiguring the new RAID with a new SATA disk.
The ACS-76200 RAID box features a user-friendly rack design that lets you easily
install three hard drives. Each drive carrier supports a one-inch high 3.5-inch form
factor drive. Security is provided by a key-locking system that prevents unauthorized
access to each disk drive.

The SATA cable is the route used for reading and writing to the array.
The power connector supplies power to the RAID box. In order to provide stable
power, we recommend to connect both power connectors on the RAID box.
The 3-pin RS-232 cable is used for remote monitoring of ACS-76200. The RS-232
port is configured with DTE and PC compatible pin assignments.
There is a triangular symbol “▲” on both PCB connector and RS-232 cable
connector, please make sure you connect in the right direction (both triangle
symbols match each other). Connecting in wrong direction will not damage RAID box,
however the terminal or GUI will not work.

This chapter contains all the information you need to decide
which RAID level to use and to prepare for installation. You will
find:
Ö A full introduction and comparison of RAID levels 0, 1 and 5
Ö
Ö Important notices on the safe operation and installation of
ACS-76200
Pre-installation planning
Introduction to RAID levels
The ACS-76200 can support the following RAID levels: 2 bays R0, 3 bays R0,
R1+Backup or Spare and R5. Which is the right level for you? The answer depends on
the application that it is used for.
RAID Level 0 offers high transfer rates, and is ideal for large blocks of data where
speed is of importance. Computer Aided Design, Graphics, Scientific Computing,
Image and Multimedia applications are all good examples. If one drive in a RAID 0
array fails however, the data on the whole array is lost.
RAID Level 1 supports three disk channels with the “spare and backup” function. It is
the function of sequence to turn on and off one disk to be the backup disk in order to
keep the data for rebuild when two disks data crash at the same time. It automatically
turns off one disk and always keeps two disks for RAID 1 operation. The Off-line disk
will be turned on and one of on-line disk will be turned off to do the daily backup
function. RAID 1+Spare allows users to set RAID 1 with two drives and the third drive
as a “hot spare” ready to be used for rebuilding data in case one of the other drives fails.
The time scheduling backup function is through StorConn GUI management software
to do it.
Further information on StorConn GUI management software to do backup function can
be found in Chapter 6, Management.
RAID Level 5 arrays offer high I/O transaction rates, and are the ideal choice when
used with on-line transaction processing applications, such as those used in banks,
insurance companies, hospitals, and all manner of office environments. These
applications typically perform large numbers of concurrent requests, each of which
makes a small number of disk accesses. If one drive in a RAID 5 array fails, the lost
data can be rebuilt from data on the functioning disks.
Further information on RAID concepts can be found in Appendix B, Glossary.
www.accusys.com.tw
User’s Manual
RAID 0
RAID 0 links each drive in the array as one huge drive. Storage capacity is determined
by the smallest drive in the array. That capacity is then applied to format all other drives
in the array. If using a 40 GB, 60 GB, and 50 GB drive in a RAID 0 array, your system
will see one huge drive of 120 GB (40 GB×3).
RAID 0 offers double or more performance under sustained data transfers when one
drive per ATA port is used. In such a configuration, unlike SCSI, ATA drives are always
available to the system. SCSI requires more management of the SCSI bus.
RAID 0: Striped disk array without fault tolerance
Characteristics:
Recommended use:
ƒ
ƒ
ƒ
ƒ
RAID 0 implements a striped disk array, the data
is broken down into blocks and each block is
written to a separate disk drive.
I/O performance is greatly improved by spreading
the I/O load across many channels and drives.
Fastest and most efficient array type but offers no
fault-tolerance.
Storage capacity = (No. of disks) × (capacity of
smallest disk)

User’s Manual
RAID 1 and 1+Spare
RAID 1 is commonly referred to as Disk Mirroring, Disk Shadowing or Disk Duplexing
as all data is duplicated across both disks. RAID 1 can only be performed with two hard
drives (with three drives, RAID 1+Spare is configured automatically, the third drive as a
hot-spare drive ready to be used for rebuilding data in case one of the other drive is
fail.). As data is identical on both disks, storage capacity is that of the smaller disk.
RAID 1 has poor performance for write operations but very high performance for read
intensive operations.
RAID 1: Mirroring
Characteristics:
ƒ
ƒ
ƒ
ƒ
ƒ
Recommended use:
Better Read transaction rate then single disks,
same Write transaction rate as single disks.
100% redundancy of data means no rebuild of data
is necessary in case of disk failure, just a copy to
the replacement disk.
All the disks have the same data.
Raid level 1 requires two drives.

User’s Manual
Backup function
When executing the backup feature, the controller turns the Disk 2 to be backup and
the Disk 3 to be RAID member disk. The controller continues to mirror data from the
Disk 1 to the Disk 3.
The backup function is available only when the RAID is safe. If the RAID health is in
good state, you may execute the backup function. The RAID health refers to the state
of both the source and target HDD. Failure of either of the HDDs causes unsafe RAID.
The backup function can only be executed through GUI.
Note
To balance the HDD usage for extending the life, the HDD will
exchange after the data scheduling backup.
www.accusys.com.tw
User’s Manual
RAID 5
RAID 5 uses a mathematical expression that compares data from two drives and
calculates a third piece of data called “parity”. Should one of the drives fail, parity data
can be used to rebuild the failed data. Under RAID 5, parity data is stored across all
drives in the array. This maximizes the amount of storage capacity available from all
drives in the array while still providing data redundancy.
RAID 5: Independent data disks with distributed parity blocks
Characteristics:
Recommended use:
ƒ
ƒ
ƒ
ƒ
ƒ
Each entire data block is written on a data disk.
Parity for blocks in the same rank is generated
on Writes, recorded in a distributed location and
checked on Reads.
Highest Read data transaction, medium Write
data transaction rate.
Relatively low ratio of ECC (Parity) disks to data
disks means high efficiency (compared to other
RAID levels).
Good aggregate transfer rate.
Storage capacity = (No. of disks – 1) × (capacity
of smallest disk)

5¼-inch devices, you can use them on the
RAID box.)
Note
In order to provide stable power, we recommend connecting
both power connectors on the RAID box.
Loading drives in the RAID box
Install drive into carrier
The ACS-76200 should be fitted with two hard disk drives. Load each drive into a drive
carrier as follows:
1. Release the handle bar by key stick
and slide drive carrier out of the RAID
box.
2. Place the disk drive in the carrier, so
that the SATA connector is lined up
with the connector inside the carrier.
3. Secure the disk drive by screwing it to
the drive carrier case.
4. Slide the loaded disk drive carrier into
the RAID box and push down the
handle bar to lock the carrier.

This chapter explains how to reconfigure the ACS-76200 and
update firmware.
Re-creating RAID
If intend re-creating a new RAID from current configuration, please follow the
instructions:
1. Remove all disk drives while power on status.
2. Power off the RAID box.
3. Set RAID level selector to the RAID level that you desired.
4. Power on the RAID box again, wait until hear the beep sounds. The RAID box is
reset.
5. Insert and lock the disk drives
6. With RAID 0, RAID1 or RAID 5 array, the initialize will begin when three disks are
installed and detected.
Caution
Re-creating array with original hard drives to different RAID
level will destroy all of data that saved on the hard drives.
Removing/replacing a drive
Swapping drives
The hot swap function is available on the RAID 1 and RAID 5 array and can be
operated during run time. RAID rebuilding will be processed automatically in the
background and the ACS-76200 RAID subsystem will record its progress. If the host
system is shut down or powered off abnormally, the ACS-76200 RAID subsystem will
continue the disk rebuilding process after power is turned on again.
Note
A hard disk should not be replaced when the system is turned
off. Doing so may leads to loss of data. Always hot swap disks in
the RAID1 and RAID5 array.

User’s Manual
What if a disk fails
If a disk drive fails, or a key switch is turned off, the red disk activity indicator of its disk
carrier will light and the alarm will sound. When this happens, you can replace the
failed SATA disk with a new one, and then turn the key switch on.
Note
The failure or removal of a single drive in RAID1 and RAID5
array will not lead to failure of the array. The failure or removal
of a single drive in a RAID0 array will lead to loss of all data on
the array and the entire array must be re-initialized.
Removing a drive from a fixed connector drive carrier
1. Insert the key to keyhole, push key to left
side for releasing the handle bar.
2.
Hold handle bar and pull out the drive
carrier from RAID box.
3. Loose screws from drive carrier.
4. Lift out the disk drive.

RAID capacity expansion and level migration
The ACS-76200 supports the following RAID reconfigurations:
(1) 2-drive R0 to 3-drive R0 (expansion)
(2) 3-drive R1/1+B/1+S to 3-drive R5 (expansion and migration)
(3) 2-drive R0 to 3-drive R5 (expansion and migration)
The reconfiguration is started by the in-band/out-band GUI commands, and it can be
done only when all disk drives in the original RAID are healthy. After the reconfiguration
GUI command is received, the ACS-76200 will start doing the reconfiguration after it is
restarted. During the reconfiguration, the ACS-76200 will also stop serving any host
commands and the host computer cannot detect the ACS-76200. After the
reconfiguration is done, the ACS-76200 will start serving host commands after it is
restarted.
Note
The original RAID level can’t be restored after the RAID
expansion.

Q
If you encounter a problem while using the ACS-76200, check this section for help.
1. When I lock a drive carrier with a disk drive in place, the red disk activity indicator
turns on and an alarm beep sounds. Why?
(a) Make sure you firmly connect the SATA connector of the HDD to their counterparts inside
the drive carrier and try again. If this does not solve the situation, go to (b).
(b) Change the disk drive with a new one and try again.
(c) Exchange the top and bottom drive carriers and try again to determine if the carrier itself
is faulty.
(d) If all of the above steps fail, contact your vendor.
2. How can I turn off the alarm beep sound when there is a hard disk failure?
Take off the failure HDD that the beeper will stop and we strong to suggest to replace a new
HDD when the drive is fail.
3. I have connected the RAID Box, but it does not appear in the motherboard BIOS.
Why?
Ensure that an array is initialized.
4. Formatting drive over 2TB capacity on Windows Vista

Array
See Disk Array.
Array Management Software
The body of software that provides common control and management for a disk array. Array
Management Software most often executes in a disk Box or intelligent host bus adapter, but
may also execute in a host computer. When it executes in a disk Controller or adapter, Array
Management Software is often referred to as Firmware.
Cache
Controller memory used to speed up data transfer to and from a disk.
Disk Array
A collection of disks from one or more commonly accessible disk controllers, combined with a
body of Array Management Software. Array Management Software controls the disks and
presents them to the array operating environment as one or more virtual disks.
Firmware
See Array Management Software.
Host Computer
Any computer system to which disks are directly attached and accessible for I/O. Mainframes,
and servers, as well as workstations and personal computers, can all be considered host
computers in the context of this manual, as long as they have disks attached to them.
Parity
Parity information is redundancy information calculated from actual data values. If any single
piece of data is lost, the data remaining and the parity information can be used together to
compute the lost data. Parity information can either be stored on a separate, dedicated drive, or
be mixed with the data across all the drives in the array.
RAID (Redundant Array of Independent / Inexpensive Disks)
A disk array in which part of the storage capacity is used to store redundant information about
user data stored on the remainder of the storage capacity. The redundant information enables
regeneration of user data in the event that one of the array member disks or the access path to
it fails. See Parity. Different RAID levels offer different data throughput speeds and fault
tolerance (data redundancy). RAID 0 does not feature redundant information but is nonetheless
considered a special type of RAID.
