- RAID Levels
RAID Level 0 : “ Disk Striping " High l/O Performance
Disk 1 Disk 2 Disk 3 Disk4 Disk 5 Disk 8 Physical
0 Improved V0 performance Is the molar reason for using RAID level 0.
’ No protection is provided against data loss due to member disk
failures. A RAID level 0 array by h‘self 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 runtlme libranes for rapid
A 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 highiy 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 1 provides both very high data reliabllity and continued
data availability In the event of a failure of an array member. When
7 a RAID level l member disk falls, 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 whlch high performance access is
required] and for which the cost of storage is a secondary issue.

Introduction
0 RAID level 5 arrays have unique performance characteristics :
A» ~ 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
A 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
A 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.

Memory Expansion
Your Disk Array comes with BMB of memory that Is expandable to
a total of T28MB by installing additional memory modules. The
optional memory expansion socket is provided for installing
memory module. These expansion memory module can be
purchased from your dealer.
- Memory Type : (SONS Extended Data Output ( EDO] SlMMs .
- Memory Size : Supports 72pin SlMMs of AME, 8MB, 145MB. 32MB,
bAMB. or i28MB.
The main-board supports many memory combinations for
a total of up to T2BMB. Memory sizes are arrived at by inserting
different combinations of SlMM DRAM modules into the RAM
sockets. The RAM sockets are numbered SIMM i and SlMM 2. The
disk array controller will automatically detect the amount of
memory installed without any jumper settings needing to be set.
The following table are the possible configurations.
Do not use SIMM modules which have an extra logic chip that
has been used to convert the memory module from asymmetric
to symmetric.

RAID Level 5 :
" Independent Access Array with Rotating Parity"
High Data Reliability & Transfer Capacity
Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical
P:Parity
When RAID Level 5 technology Is combined with cache memory to
improve Its write performance, the resutt 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 0 RAID Level D array. In
fact, fora 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 D
array of equivalent usable capacity.
0 A RAID level 5 array performs best in applications where data and
V0 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 3 :
" Parallel Transfer Disks with Parity "

Disk1 DiskZ Disks Disk4 DiskS Disks Physical
P : Parity
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 7
single stream V0 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 :
0 They operate on large data objects such as graphical image
processing. CAD/CAM files, and others.
0 They are non-Interactive applications that process large data
sequentially.
They usually request a large amount of data (32KBytes or more) with
each l/O request, _
,____L____;—
Introduction
0 RAlD 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 walling
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.
Introduction
General RAID Conceots
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
Arrays member Disks or the access path to it fails.
Benefits of RAID
I . 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 )
Introduction
This section provides an overview of the features. For more detailed
information, please refer to the technical specifications appendix
