- Auto rebuild : when a replacement disk installed [or by using hot
spare disk ], Arena provides automatic data rebuild without any
commands or functions keyed In. (Transparent to Host 1
Efficient maintenance
- 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 can remove and install the " Hot Swap '
parts without Interrupting data access while the Arena is on.
- The ' Hot Swap " parts include the Hard Disk Drive, Redundant
Power Supply Unit and Cooling Fan.
Introduction
General RAID Conce ots
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 0 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 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
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 slgnificantty 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
RAID Levels
RAID Level 0 : " Disk Striping " High l/O Performance
,- Disk 1 Disk2 Disk 3 Disk 4 Dlsk 5 DiskG Physical
0 Improved I/O performance is the major reason for using RAID level 0.
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 suiiabie 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 stmcfures 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.
F4”
Introduction
0 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.
Introduction
RAID Level I : “ Disk Mirroring " High Data reliability
Physical
RAID level 1 provides both very high data reliability and continued
data availability in the event of a failure of an array m mber. When
0 RAID level 1 member disk fails, array management %fiware simply
directs all application requests to the surviving membe.
- " 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 :
" Parallel Transfer Disks with Parity -
High Data Reliability & Highest Transfer Capacity "
Diski Disk2 Disk3 Disk4 Disks Disks Physical
PzParity
RAID Level 3 technology use a dedicated partly 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 V0 with a high data transfer rate.
RAlD Level 3 is optimal for applications in which large block of H
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 flies, 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 VO request. ,

0 The dlsflncllve performance characteristics of RAID Level 3 :
- - RAID Level 3 prcvldes excellent performance for dc’rcr
Transfer-Intensive cppllcollons.
- RAID level 3 In no’r well sulled for Transaction processing or other
I/O request-imens'rve appllcoflons.
Introduction
RAID Level 5 : ~
" Independent Access Array with Rotating Parity "
High Data Reliability ik 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 result can be used In any A
applications where general purpose disks would be suitable.
For read only or read mostty appilcatlon V0 loads, RAID Level 5 ,_
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 stightty 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
V0 load characteristics match their capabilities :
- Data whose enhanced availability ls worth protecting, but for
which the value of full dlsk mirroring ls questionable.
- High read request rates. ~
- Small percentage of writes in V0 load.
__J____;
Introduction
0 RAID level 5 arrays have unlque performance characterts'tlcs :
- The data can be recalculated or regenerated, uslng partly,
when any drive in the array falls.
- When the falled drrve ls replaced, elther automatlcally It the
' subsystem contalned a hot spare driver or by user interventlon
during a scheduled malntenance period, the system wIIl be
restored rls full data redundancy configuratlon by rebulldlng all
of the data that had been stored on the falled drlve onto the
new drlve. Thls Is accomplished uslng partly Information and
data from the other data disks. Once the rebulld process Is
complete, all data is again protected from loss due to any
fallure of a slngle disk drlve.

641MB, or TQBMB
The main-board supports many memory combinations for w
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 l and SIMM 2. The ’
disk array controller will automatically detect the amount of
memory installed without anyiumper settings needing to be set.
The following table are the possible configurations.
