Introduction
2 Features I
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 :
Easy Operation
As everyone knows. conventional Disk Arrays are designed for
experienced computer specialists. To solve complicated and time
consuming operating procedures, Arena came up with a
revolutionary idea :
— innovative Plug And Play RAlD
As compared to a conventional Disk Arrays long—winded setup
procedures, Arena can be ready to go after using the simple step
by step built—in setup program.
Ultra High performance
Arena combines an extremely high speed microprocessor with the
latest chip set, SCSI hardware technoiow, perfect firmware and an
artistic design. The result is one of the fastest, most reliable Disk Array
systems on the market.
- Supports Virtually all popular operating systems platforms and
network environments because it works independently from the
0.8,
- Fast /Wide / Ultra Wide SCSI channel interface to your Host
computer, up to AOMB data transfer rate provides the processing
and access power for you to handle complex and large files.
- Selective SCSl 1D 0 ~ is , support with active termination.
- Tagged-command queuing 1 allows processing of up to 255
simultaneous data requests.
- Selective RAlD levels 0, i, 0+1, 3 or 5.
- Build—in iéMB cache memory, expandable up to 256MB.
- Serial communication port [ Monitor Port 1 permits array controller
operation through a standard Vii OO terminal [or equrvalenti
Introduction
Solid reliability
- Automatic tailed disk drive detection.
- Auto rebutid ‘ when a replacement disk installed [or by using hot
spare disk l, Arena provides automatic data rebuild without any
commands or functions keyed in. (Transparent to Host i
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 drives 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 1 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 Conceéts I
Correct installation of the disk array requires an understanding of
RAID technology and the concepts described in this section.
Definition
RAID is an acronym ot 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 “rt fails.
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
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 typicaity simplified because it is easy
to replace individual disks and other components while the
system continues to function. [ Hot swap support l

RAID Levels I
RAlD Level 0 : “ Disk Striping " High l/O Performance
Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical
0 Improved i/O performance is the maior 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 suitable for
data that can be reproduced or is replicated an other media.
0 A RAID level 0 array can be particularly useful for :
- Storing program image libraries or runtime 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 at a failure.
- Collecting data from external sources at very high data transfer
rates.
Introduction
0 RAID level 0 arrays are not particularly suitable for 1
- Applications which make sequential requests for small amount of
data. These applications will spend most of their l/O time waiting
(or disks to spin, whether or not they use striped arrays as storage
media.
~ Applications which make synchronous random requests for small
amounts of data

Optional
Physical
RAlD level 1 provides both very high data reliability and continued
data availability in the event of a failure of an array member. When
a RAlD level i member disk fails, 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 which high performance access is
required, and for which the cost ot storage is a secondary issue.
Introduction
RAlD Level 3 :
" Parallel Transfer Disks with Parity "
High Data Reliability & Highest Transfer Capacity
Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical
P:Parity
RAID Level 3 technology use a dedicated parity disk to store
redundant information about the data on several data disks.
RAlD Level 3 is an excellent choice for applications which require
single stream l/O with a high data transfer rate.
RAID Level 3 is optimal for applications in which large block of
sequential data must be transferred quickty, these applications are
usually of one of these types :
0 They operate on large data objects such as graphical image
processmg, CAD/CAM tiles, and others,
0 They are non-interactive applications that process large data
sequentially
They usually request a large amount of data i32l+
