RAID Levels
RAID Level 0 : " Disk Striping " High l/O Performance
Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical
0 Improved l/O performance is the major reason for using RAID level 0.
ONo protection is provided against data loss due to member disk
failures. A MID level 0 arr
ay by itself is thus an unsuitable storage
medium for data that can not easily be reproduced, or for data that
rltical 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 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 faliure.
- Collecting data from external sources at very high data transfer
rates.

- When the failed drive is replaced, either automatically if the
subsystem contained a hot spare drive, or by user lnieNenrion
during a scheduled maintenance period, ihe system will be
resrorecl its full data redundancy configuration by rebuilding all
of the dara that had been stored on the failed drive onto the
new drive. This is accomplished using palliy information and
complete, all data is again protected from loss due to any
failure of a single disk drive.

Memory Expansion —
Your Disk Array comes with ibMB of memory that is expandable
to a total of 256MB 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 : 60NS Extended Data Ouiputi EDO )S|MMS .
- Memory Size : Supports 72pin SiMMs of 4MB, aMB, iéMB, 32MB. ‘ _
GAME, or 128MB
The main-board supports many memory combinations for _
a total of up to 256MB. Memory sizes are arrived at by inserting
different combinations of SIMM DRAM modules into the RAM
sockets. The RAM sockets are numbered SIMM i and SIMM 2. The e
dlsk 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. _

Introduction
RAID Level 5 :
" Independent Access Array with Rotating Parity -
High Data Reliability 8c Transfer Capacity "
Disk1 Dlsk2 Disk3 Diskd Disks Disks Physical
P : Parity
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 dlsks would be sultable.
For read only or read mostty application l/O loads, RAID Level 5 a
performance should approximate that of 0 RAID Level 0 array. In ‘
fact, for a given user capacity, RAID Level 5 read performance
should normally be sllghtty better because requests are spread "'
across one more members than they would be in 0 RAID Level 0
array of equivalent usable capacity.
0 A RAID level 5 array performs best in applications where data and
I/O load characteristics match thelr capabilities :
- Data whose enhanced avallabllity Is worth protecting, but for
whlch the value at full dlsk mlrroring ls questionable,
- High read request rates. -
- Small percentage of wrltes ln VO load.

Introduction “
RAID Level 3 : “
" Parallel Transfer Disks with Parity "
High Data Reliability & Highest Transfer Capach "
Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical
P:PCIrl‘ly
RAID Level 3 technology use a dedicated partly disk to store A
redundant Information about the data on several data disks.
RAID Level 3 is an excellent choice for applications which require
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 V0 request.
|____i___“
Introduction
0 RAID level 0 arrays are not particularly suitable for :
- Applications whlch males sequential requests for small amount of —
data. These applications will spend most of their l/O time waiting
for dlsks 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 Conce ots c
Correct Installation of the disk anay 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 falls.
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
falls, 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 wstem 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 typicalty 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 technlcal specifications appendix
at the end of this manual .
