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
8
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.

Read the pre-installation notices earlier in this chapter before proceeding with
installation.
RAID SYSTEM is normally supplied with 512MB DDRII-533/667 SDRAM installed.
There's no set formula to determine how much cache memory to use, but as a
general rule, a workstation, with mostly very large files, 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.
Memory serves as the data buffer to increase the CPU utilization rate and minimize the overhead of data
accessing , thus, improves the overall performance. YB-12S3/16S3/24S3 supports up to 2GB DDRII-
533/667 DIMM type with ECC type memories .
The DDR memory socket is used 240-pin DDR2 DIMM socket . Use 25 degree DDR2 DIMM socket
DDRII SDRAM DIMM specifications:

1: Removing the controller module from Raid system.
2: Open the cover of controller module .
3. Insert a memory module into the memory socket .
4.Close the cover of controller module .
Before starting any kind of hardware installation, please ensure that all powe r
switches have been turned off and all power cords disconnected to prevent
personal injury and damage to the hardware
Use screws provided with RAID system only. Longer or shorter screws may
cause electric shorting or un -proper installed.
Static electricity can damage electronic components. To guard against such
damage:
Work in a static-free environment
Wear a grounded anti -static wrist strap

Battery Back
upModul
e (BBM)
The external RAID controller operates using cache memory .The battery Backup Module is
an add-on module that provides power to the external RAID controller cache memory in
the event of a power failure. The Battery Backup Module monitors the write back cache
on the external RAID controller, and provides power
to the cache memory if it contains data not yet written to the hard drives when power failure
occurs.
