An LCD status panel displays a comprehensive readout of the
operating status, and the HDD LED indicators on each HDD tray
display the individual HDD status.
When disk failure occurs on a member disk of the disk array, the
built-in buzzer sounds simultaneously and LCD status panel also
points out the location of the failed hard disk drive. In the
meantime the LED HDD status indicator will light up “ Red “on
the failed HDD tray , according the LED indicator on the HDD
tray you can perform quick, efficient and correct maintenance.
Hot Swap : allows you to remove and install the “ Hot Swap “
parts without interrupting data access while the system is on.
The “ Hot Swap “ parts include the Hard Disk Drive, Redundant
Power Supply Unit and Cooling Fan.

Introduction
Correct installation of the disk array requires an understanding of
RAID technology and the concepts described in this section.
Definition
RAID is an acronym of Redundant Array of Independent Disks .
A RAID is a Disk Array in which part of the storage capacity is used
to record redundant information about the 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’s member Disks or the access path to it fails.
Benefits
of
RAID
1. Secure Data
RAID is an emerging storage technology with the potential to
revolutionize the data storage technology. A typical RAID unit
contains a set of disk drives, typically two to six, which appear to
the user to be equivalent to a single large capacity disk drive.
The remarkable benefit of disk array is that if any single disk in the
RAID fails, the system and array still continues to function without
loss of data. This is possible because the redundancy data is
stored on separate disk drives and the RAID can
reconstruct the data that was stored on the failed disk drive.
2.
Increases
system
performance
As the effective seek time for finding data on a disk can
potentially be reduced by allowing multiple simultaneous access
of different data on different disks. Utilizing parallel reads and
writes of the data spread across the disks in the array, the data
transfer rate can be increased significantly over that of a single
disk.
3. Easy maintenance
RAID system maintenance is typically simplified because it is
easy to replace individual disks and other components while the
system continues to function. ( Hot swap support )

Improved I/O performance is the major reason of using RAID
level 0.
No protection is provided against data loss due to member
disk failures. A RAID level 0 array by itself is thus an unsuitable
storage medium for data that can not easily be reproduced,
or for data that must be available for critical system operation.
It is more suitable for data that can be reproduced or is
replicated on other media.
A RAID level 0 array can be particularly useful for :
Storing program image libraries or runtime libraries for rapid
loading, these libraries are normally read only.
Storing large tables or other structures of read only data for
rapid application access. Like program images, the data
should be backed up on highly reliable media, from which it
can be recreated in the event of a failure.
Collecting data from external sources at very high data
transfer rates.
RAID level 0 arrays are not particularly suitable for :
Applications which make sequential requests for small
amount of data. These applications will spend most of their
I/O time waiting for disks to spin, whether or not they use
striped arrays as storage media.
Applications which make synchronous random requests for
small amounts of data.

RAID level 1 provides both very high data reliability and continued
data availability in the event of a failure of an array member. When
a RAID level 1 member disk fails, array management software
simply directs all application requests to the surviving member.
RAID level 1 is suitable for data for which reliability requirements are
extremely high, or for data to which high performance access is
required, and for which the cost of storage is a secondary issue.

RAID Level 3 technology use a dedicated parity disk to store
redundant information about the data on several data disks. RAID
Level 3 is an excellent choice for applications which require single
stream I/O with a high data transfer rate.
RAID Level 3 is optimal for applications in which large block of
sequential data must be transferred quickly, these applications are
usually of one of these types :
They operate on large data objects such as graphical image
processing, CAD/CAM files, and others.
They are non-interactive applications that process large data
sequentially.
They usually request a large amount of data (32KBytes or more)
with each I/O request.
The distinctive performance characteristics of RAID Level 3 :
RAID Level 3 provides excellent performance for data
transfer-intensive applications.
RAID level 3 is not well suited for transaction processing or
other I/O request-intensive applications.

When RAID Level 5 technology is combined with cache memory to
improve its write performance, the result can be used in any
applications where general purpose disks would be suitable.
For read only or read mostly application I/O loads, RAID Level 5
performance should approximate that of a RAID Level 0 array. In
fact, for a given user capacity, RAID Level 5 read performance
should normally be slightly better because requests are spread
across one more members than they would be in a RAID Level 0
array of equivalent usable capacity.
A RAID level 5 array performs best in applications where data
and I/O load characteristics match their capabilities :
Data whose enhanced availability is worth protecting, but for
which the value of full disk mirroring is questionable.
High read request rates.
Small percentage of writes in I/O load.

Introduction
RAID level 5 arrays have unique performance characteristics :
The data can be recalculated or regenerated, using parity,
when any drive in the array fails.
When the failed drive is replaced, either automatically if the
subsystem contained a hot spare drive, or by user intervention
during a scheduled maintenance period, the system will be
restored its full data redundancy configuration by rebuilding
all of the data that had been stored on the failed drive onto
the new drive. This is accomplished using parity information
and data from the other data disks. Once the rebuild process
is complete, all data is again protected from loss due to any
failure of a single disk drive.

After completing the hardware installation, the disk array must be
configured and the logical unit must be initialized before it is ready
to use. This can be accomplished through the following user
interfaces :
Front Panel function keys ( LCD Display )
or
VT100 terminal connected through the serial port ( Monitor Port)
or
The GUI S/W (Graphical User Interface). Defails please refer to the
Global-Eyes CD-Rom.
The LCD display panel and a VT100 terminal can not be used
at the same time.
This chapter guides you through setting up your Disk Array for the
first time. This chapter contains information on setup. The setup
program is a menu-driven utility which enables you to make
changes to the configuration and tailor your Disk Array to your
individual needs.
The setup program is a ROM-based configuration utility which
displays the Disk Array’s status and allows you to set up the
parameters. The parameters are stored in a nonvolatile battery
backup CMOS RAM which saves the information even when the
power is off.
By using an easy-to-use user interface, you can configure such
items as :
RAID Level
Hot Spare Disk
SCSI ID
Password ( For protection from unauthorized use )
Firmware update (VT100 Terminal mode only) —- for update
procedures please refer to Chapter 4 : Advanced information.
The setup program has been designed to make it as easy to use
as possible. By using a menu-driven program, you can scroll
through the various sub-menus and make your selections among
the various predetermined choices.

WARNING
Saving configuration changes causes the disk array controller’s
working parameters to change. This can produce unpredictable
results if it occurs during Host and Array activity. All activity to the
controller should be stopped before saving configuration changes.

There are two LED indicators on the front panel which display the
status of the redundant power supplies. While the power supply
is working properly the two LED indicators light up “ Green “, if any
one of them fail, the LED indicator will go off and the redundant
power supply buzzer alarm will sound.
When you need to replace the redundant power supply unit ,
refer to the redundant power supply status LED indicator on the
front panel to find the failed power supply unit and follow these
steps to swap it.
a.
Unscrew
