For Europe
This drive is in conformity with the EMC directive.
Federal Communications Commission (FCC) Statement
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules.
Those limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determin ed
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
Reorient or relocate the receiving antennas.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circlet different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Warning:
A shielded-type power cord is required in order to meet FCC emission limits and also to prevent
interference to the nearby radio and television reception. It is essential that only the supplied power
cord be used.
Use only shielded cables to connect I/O devices to this equipment.
You are cautioned that changes or modifications not expressly approved by the pa rty responsible for
compliance could void your authority to operate the equipment.

The RAID SYSTEM is designed to meet today’s high volume, performance storage requirements from
rapidly changing business environment. It provides a maximum data protection and exceptional
performance in a storage subsystem. Target usa ge ranges are set from small business to departmental and
corporate server needs. The RAID SYSTEM is designed for easy integration, smooth data expansion and
server migration.
The RAID SYSTEM supports the following features:
Intel 800Mhz IOP341 64bit storage processor
Support cache memory size up to 2GB in DDRII-533/667 DIMM type with ECC embedded
Support 12/16/24 SAS/SATAII disk channels.
Dual 4Gb FC host interface support by FC to SAS
Dual mini SAS 4 x 3 SAS Ports support by SAS to SAS
Support RAID level 0, 1, 1+0, 3, 5, 6, 30, 50, 60 and JBOD
Redundant and Hot Swappable Fan, Power and Drives.
Hot Swap, Hot Spare and Automatic Drive Rebuild Supported.
Configuration and environmental information is accessible either via the control panel or Serial Port or
10/100 Ethernet LAN port.
E-mail event notification.
Load sharing hot swappable redundant power system with PFC function
Host System independent.
Operating System independent.

Unpacking & Checking The Equipment
Before unpacking the RAID SYSTEM, prepare a clean, stable surface to put on the
contents of your RAID SYSTEM shipping container. Altogether, you should find the
following items in the package :
Fibre to SAS RAID system
RAID System x1
RAID system Hardware Installation Guide (CD media )
RAID system Software Operation Manual (CD media )
RS232 cable x1
Power Cord x 2 ( 24Bay x 3)
FAN x 1
HDD tray x 1
Mounting screws (bag) ×1
SAS to SAS RAID system
RAID System x1
RAID system Hardware Installation Guide (CD media )
RAID system Software Operation Manual (CD media )
RS232 cable x1
Mini SAS to Mini SAS Cable x 1
Power Cord x 2 ( 24Bay x 3)
FAN x 1
HDD tray x 1
Mounting screws (bag) ×1
To avoid the unmatched cable between the Fibre HBA in the Host and
Fibre-SAS RAID SYSTEM, Fibre-SAS RAID system doesn’t include the Fibre
interface with the standard configuration. There are many different kinds of
Fibre connectors on varied of Fibre HBAs.

Hardware Operation Manual

What else you need
Hard disk drives (different RAID levels requires different numbers of HDDs ). Refer to
Software Operation manual for more detail information.
Host computer with Fibre interface (Fibre-SAS RAID SYSTEM)
Host computer with SAS interface (SAS-SAS RAID SYSTEM)
Static grounding strap or electrostatic discharge (ESD) safe work area
Dedicated terminal or PC with third party communication software that supports ANSI
terminal emulation (required for viewing Monitor Utility)
The hard drives in a RAID system should match in size and speed. All drives in
any array should be identical models with the same firmware versions. RAID
system can use any size drive, however the smallest drive will determine the
size of the array.
There's no set formula to determine how much cache memory to use, but as a
general rule, a workstation, with mostly very large fi les, such as for audio or
video editing and playback, graphics or CAD files, can benefit from a large
cache. File servers, with multiple random access of varying file size, generally
have little or no performance improvement with additional cache.
RAID system do not require the installation of different drivers for use with
different operating systems. RAID system is independent and transparent to
the host operating system.

When selecting a location for your system, be sure to allow an adequate space. The system has vents
around it which will require a minimum of 3 inches of unobstructed space for airflow. Openings in the
equipment should be blocked, or there may be a n issue of reliability problems with your syst em. A system
product should never be place around a radiator or heat register.
