Introduction
General RAID Concepts
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 for 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 : " Disk Striping " High I/O Performance
RAID Levels
1-6
Introduction
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.
1-7
Introduction
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.

Introduction
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.

Introduction
The distinctive performance characteristics of RAID Level 3 :
RAID Level 3 provides excellent performance for data
transfer-intensive applications.
RAID level 3 in not well suited for transaction processing or other
I/O request-intensive applications.
Introduction
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.

Chapter 3 : " Configuration "
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 )
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
Termination
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.
Configuration from the front Panel
The LCD Display front panel function keys are the primary user
