commands or functions keyed in. ( Transparent to Host)
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.

RAID Levels
’ RAID Level 0 : “ Disk Striping " High I/O Performance
Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical
0 Improved I/O performance Is the major reason for uslng RAID level 0.
0 No protection is provlded against data loss due to member dlsk
failures. A RAID level 0 array by Itself ls 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.
0 A RAID level 0 array can be partlcularly useful for :
- Storing program image Ilbraries or runtime libraries for rapid
loadlng, these libraries are normally read only.
- Storing large tables or other structures of read only data for rapid
~ application access. lee program Images, the data should be
backed up on hlghly reliable media, from whlch if can be
recreated in the event of a failure.
’ - Collecting data from external sources at very hlgh data transfer
rates.

Introduction
0 RAID level 5 arrays have unique performance characteristics :
- The data can be recalculated or regenerated, using parity,
when any drive in the array falls.
- When the failed drive ls 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.

Memory Expansion
Your Disk Array comes with BMB of memory that is expandable to
a total of 128MB by Installing additional memory modules. The
optional memory expansion soaket Is provided for installing
memory module. These expansion memory module can be
purchased from your dealer.
- Memory Type : The DRAM can be either 60NS or 70NS, supports
both Fast Page Model FPM] and Extended Data Output ( EDO )
SlMMs .
' Memory Size : Supports 72p|n SlMMs of AME, BMB, léMB, 32MB or
64MB
The main-board supports many memory combinations for
a total of up to l 28MB. 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 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 chlp that
has been used to convert the memory module from asymmetric
to symmetric.

P : Partly
When RAID Level 5 technology Is combined with cache memory to
improve its vvrlte performance, the result can be used in any
applications where general purpose disks would be suitable.
For read only or read mostly application l/O loads, RAID Level 5
performance should approximate that of 0 RAID Level 0 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 0 RAID Level 0
array of equivalent usable capacity
0 A RAID level 5 array performs best in applications where data and
l/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.
H "_
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 l/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
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 ls 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
transter 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
at the end of this manual .
Arena includes the following features : 7
