This chapter introduces the features and capabilities
of the ExaSAN A08S-PS.

The ExaSAN A08S-PS is a RAID system that provides superior functionality
and performance for managing your information.
With a Java based GUI, the RAIDGuard X Server and Client software offers
improved functionality and manageability. Using the latest Intel XScale® 64-bit
RISC processor, ExaSAN A08S-PS supports up to 8 x SAS & SATA hard disk
drives, making it ideal for applications that require high storage capacity and
fast access such as video editing, digital surveillance, file servers and shared
storage. Utilization of SAS hard disk drives provides additional performance
advantages in your workstation environment.
External PCI Express technology enables disk arrays to be used in tune with
editing workstation via high-bandwidth, ensuring smooth handling of heavy
loaded and time critical applications such as editing of uncompressed,
multi-stream HD videos or film post-production.
Data protection is one of the key features of ExaSAN A08S-PS. Online
recovery and reallocation protect against disk failure and bad sectors. Disk

Chapter 1 – Overview

SAS (Serial Attached SCSI)
The Accusys RAID system is designed for use with the latest SAS hard disk

drives. SAS allows data transfer up to 3 or 6 Gbps, and is backwards
compatible with second-generation SATA drives. SAS offers several high
performance advantages, including speed, I/O frequency, high mean time
before failure (MTBF) and simultaneous support for many users.

SATA (Serial Advanced Technology Attachment)
The Accusys RAID system is designed for use with the latest Serial ATA II

hard disk drives. Serial ATA (often abbreviated as SATA or S-ATA) allows data
transfer up to 3 Gbps and is compatible with older Parallel ATA standards. It
has an additional advantage parallel ATA in that cables are thinner, so airflow
within computer cases is less impeded, and can extend to one meter in length
(against only 40 cm for parallel ATA).

PCI EXPRESS X 4

Developed by Intel in 2004, PCI Express has been developed to match the
speed of CPUs. It provides a serial communications channel that provides up
to 2.5 Gbits/sec in each direction of a pair of wires. The 4 refers to the number
of pairs of wires, therefore allowing a maximum of 10 Gbits/sec transfer.

FIRMWARE

Appropriate firmware must be loaded into the RAID system for it to function.
The Accusys RAID system is shipped with firmware preloaded. Check the
installation CD that came with the package to find a backup firmware copy.
You can also periodically check the vendor’s web site to find the latest
firmware version for use with the RAID system. See ftp.accusys.com.tw for
upgrades.

EFI

The Accusys RAID system contains an internal EFI, which can be used to
configure a RAID array instead of using the RAIDGuard X GUI. The EFI is
accessed as the RAID system boots up and contains all the functionality of the
RAIDGuard X GUI. The BIOS and EFI may be upgraded using the RAIDGuard
X GUI. See ftp.accusys.com.tw for upgrades.

What Else You Need

z SAS or SATA hard disk drives.
z Host server with spare PCIe x4 slot.
z Static grounding strap or electrostatic discharge (ESD) safe work area.

The PCIe slots on some motherboards are for graphics

cards only. Check with the motherboard vendor for
compatibility.

Different RAID levels require different numbers of hard

disk drives. See the RAIDGuard X User's Manual to
determine how many hard disk drives you require.

The hard drives in a RAID should match in size and

speed. All drives in any array should be identical models
with the same firmware versions. The smallest drive will
determine the size of the array.

Many motherboards only come with one PCI Express

interface. Before installation, make sure there is one free.

Maintenance

28

Chapter 7 – Maintenance

Chapter 7

MMaaiinntteennaannccee

This chapter explains how to identify and replace
faulty modules of your RAID system.

You may need to send the ExaSAN A08S-PS RAID system to your service
provider for maintenance. Always power on the RAID system before the host
server to ensure that data on the hard disk drives are properly accessed and
displayed correctly.

When a module fails, an audible alert sounds. To turn off

the audible alert, open RAIDGuard X and disable the
beeper.

Replacing a Disk

One or multiple hard disk drives may be malfunctioning if you hear three short
beeps when the system is powering on. In the event of disk failure, the
power/error indicator LED on the front of the disk tray and the corresponding
LED light on the front of the RAID system both turn red.
To confirm that the source of the beeper alert is disk failure, open RAIDGuard

X and view the status of the hard disk drives. If any hard disk drive shows up
as "failed", replace it with the following steps.

The hard disk drives are hot-swappable. They can be

removed and inserted while the RAID system is powered
on and operating.

29

ExaSAN A08S-PS User’s Manual

Before replacing the hard disk, make sure the new disk is

greater or has the same memory capacity than the failed
disk.

1. Unlock the rear panel door and
pull it open.

2. Push the button on the disk tray
to release the handle, and pull
the disk tray out.

3. Loosen the screws on the disk
tray and slide the hard disk
drive away from the
connectors to release it.

4. Insert the new hard disk drive
into the disk tray, with the
connectors facing outward.

5. Slide the connectors into
place, and secure the hard
disk drive onto the disk tray
with four screws.

6. Keep the handle lifted as you
insert the disk tray back into
the empty slot.

7. Push the handle down to lock
the disk tray into place.

8. Close and lock the rear panel.

Controller Maintenance

The controller may be malfunctioning if you hear long beeps with one second
pauses in-between when the system is powering on.
To confirm the state of the controller, view the controller status in
RAIDGuard X.
If the controller is the source of the beeper alert, power off the system and
contact your service provider for a replacement controller.

30

Chapter 7 – Maintenance

When a controller has been removed, the hard disk drives

it controls are not active, and data stored on the hard disk
drives is not lost.

Power Supply and Fan Module Maintenance

The power supply or fan module may be malfunctioning if you hear three short
beeps when the system is powering on. In the event of power supply failure,
the power supply fail indicator LED on the rear of the RAID system also turns
red.
To confirm which component is malfunctioning, view the power supply and fan
module status in RAIDGuard X.
Once you have determined the source of the beeper alert, power off the
system and contact your service provider for a replacement power supply or
fan module.

The power supplies are NOT hot-swappable. Do not

remove or insert power supplies while the RAID system is
powered on and operating.

If no replacement is available for a faulty fan module,

power off the RAID system immediately to prevent the
system from overheating.

The fan modules are NOT hot-swappable. Do not remove

or insert fan modules while the RAID system is powered
on and operating.

Appendix A – Q&A

Appendix A

QQ && AA

Q1: When turning on the Windows host, “Find no RAID card” appears, how

can this be handled?

Ans: Please make sure the PCIe cable is properly connected to the back of

the host server and RAID system. In Windows, check “Device Manager”
to confirm that the correct driver has been installed for the Re-drive
card.

Q2: When turning on the MAC host, after entering the GUI and adding a

controller, there is no device listed. How can this be dealt with?

Ans: Please first confirm whether the hardware environment of the RAID

system is functional, and also make certain that the system drivers have
been correctly installed. Next, go to "Utilities > System Profiler >
Software > Extensions" and check whether the Accusys6xxxx is listed.
In order to confirm whether GUI Server Service is running on the
system, go to "Utilities > Activity Monitor" and check whether the
program name DTRGuiSrv01 is under the program column. If the
situation persists after doing the above, please again double check that
the hardware environment is not the source of the problem, and reinstall
using Mac Installer.

Q3: Why is it that my RAID system has an actual capacity of more than

2 TB, but in windows XP and windows 2000, it will only do a full format
of less than 2 TB of capacity? How can this be resolved?

Ans: Since Windows XP 32 bit & Windows 2000 don’t support GPT, so they

can only continue to use MBR (Master Boot Record), and MBR only
supports up to 2 TB on one volume. To see more than 2 TB on a single
volume in Windows XP or 2000, go to RAIDGuard X, select “Create
Array” and set the sector size to 4096 bytes. By doing this, Windows XP
will be able to format an MBR volume to greater than 2 TB. However, if
sector size is set to 4096 bytes, it can lower the performance a bit.

33

ExaSAN A08S-PS User’s Manual

Q4: In the Vista & Windows 7 Environment, after having confirmed that the

files on the installation CD have been completely installed, why does it
still show “Find no RAID card”?

Ans: Windows Vista has the built-in ability to automatically reduce the

potential of security breaches in the system. It does that by
automatically enabling a feature called User Account Control (or UAC
for short). When UAC function is enabled, the RAIDGuardX Server can
not detect the controller and thus displays the message “Find no RAID
card”. To resolve this, you have to disable UAC or run the RAIDGuardX
Server “as administrator”.

Vista:

a. Control Panel ¨ User accounts ¨ Change security settings ¨

Deselect “Use User Account Control (UAC) to help protect your
computer”.

b. Restart the Computer to turn off the UAC.

Windows 7:

a. Type “MsConfig” in Start Search to start System Configuration,

then go to Tools tab, select Change UAC Settings, then click on
Launch button.

b. Slide the slider bar to the lowest value (towards Never Notify),

with description showing Never notify me.

c. Restart the computer to turn off the UAC.

Q5: Why doesn't performance reach the levels it should while testing the

A08S-PS? Why isn’t performance steady enough?

Ans: If performance is unsteady or not good enough, in many cases the HDD

is the cause. Since the A08S-PS is a high efficiency product, there is
extreme demand placed on each HDD. As a result, if one of the HDDs
has a small performance problem, it could still impact the entire
system’s output efficiency.

Q6: Why is it that after my A08S-PS is more than half full, efficiency is

lowered significantly?

Ans: When capacity surpasses one half, efficiency lowers. This is caused by

the HDD itself. As a result of the HDD’s engineering, the more occupied
disk space, the lower the read/write efficiency. Since our A08S-PS is a
high-efficiency product, when all HDDs are reading/writing and reach
full capacity, causing a drop in HDD efficiency, the efficiency decline
can also carry over to our A08S-PS.

34

Appendix A – Q&A

Q7: When inserting the HDD into my A08S-PS, why does RAIDGuard X

show the HDD mode as Lock?

Ans: When a HDD can be locked, it shows that this hard drive contains

metadata created by the A08S-PS, and shows that it was previously
used. To erase the data on the HDD, simply unlock the HDD.

Q8: How can a spare HDD be set-up?
Ans: The A08S-PS automatically treats an unused HDD as Globe Spare

HDD. If you want to set a particular HDD as a spare HDD, just make
sure you don’t set it as part of an array or JBOD.
