provide Informofion on general RAID concept
Introduction
Solid reliability
- Automatic failed disk drive detection.
- Auto rebuild : when a replacement disk installed (or by using hot
spare disk ), Arena provides automatic data rebuild without any
commands or functlor‘s 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 tailed 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 Suppty Unit and Cooling Fan.
Introduction
RAID Levels
RAID Level 0 : " Disk striping " High I/O Performance
Disk 1 Dlsk 2 Dlsk 3 Disk 4 Disk 5 Dlsk 6 Physical
olmproved l/O performance Is the motor reawn for using RAID level 0.
o 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 pariicuiariv 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 failure.
- Collecting data from external sources at very high data transfer
rates,
Introduction
RAID Level I : " Disk Mirroring “ High Data reliability
Disk 1 Disk2
Optional
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 falls, array management software simply
directs all application requests to the surviving member.
RAID level I 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
O 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
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 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 ls
complete, all data is again protected from loss due to any
failure of a single disk drive.
Introduction

Based on the needs of 0 Disk Arrays capacity, data availability, and
overall performance, you can select a proper RAID level for your
Disk Array. The supported RAID levels are shown In below :

Memory Expansion
Your Disk Array comes wlth 1 (SM! 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 Output [ EDO )SIMMs .
- Memory Size 1 Supports 729in SlMMs of 4MB, BMB, léMB, 32MB,
64MB, or i28MB
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 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 chip that
has been used to convert the memory module from asymmetric
to symmetric.

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 VO 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 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
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.

RAID Level 3 Is an excellent choice for applications which require

RAID Level 3 is optimal for applications in which large block of N
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

Introduction
0 RAID level 0 arrays are not particularty suitable for :
- Appllcaflons whlch make sequential requests for small amount of —
data. These appllcations will spend most of fhelr I/O tlme walling
for dlsks to spln, whether or not they use striped arrays as storage
medla. —
- Applicatlons 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 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 —~
Arroy's member Disks or the access path to it falls,
Benefits of RAID ~
1 . Secure Data
RAID Is on 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 a
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 e
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 ~
potentlaity 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 a
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 ]
