1.1.1 Product Introduction
This hardware manual briefly introduces the Galaxy GHDX2-2430S-16F4D
Fibre-4G to SATA-II Raid storage subsystem shown in
Figure 1-1
.
Through this manual, you will gain the knowledge of each hardware
components, installation procedures, monitoring functions, connection
topologies and hardware maintenances. The GHDX2-2430S-16F4D comes
with single RAID
controller, two (2) 4Gbps
(FC-4G) host channels, and
sixteen (16) drive bays for
SATA-II disk drives. The
RAID controller provides a
pre-installed 256MB DDR
RAM DIMM module. If preferred, a DIMM module with up to 2GB
capacity can be installed.
The metal container in which the controller board is pre-installed is referred
to as the “controller module.” The controller module is accessed through the
rear of the GHDX2-2430S-16F4D and is comprised of a PCB board, a rear
faceplate, and a metal canister. An optional battery backup unit (BBU) can
be installed in the middle of the controller module when viewed from the
rear of the subsystem. The independent BBU is also accessible and hot
swappable through the rear panel of GHDX2-2430S-16F4D.
I/O signals/commands transmitted between the controller and drives at the
front of the subsystem pass through a non-user-serviceable backplane board.
The backplane is connected to a maximum of sixteen (16) hard drives that
you purchase separately and install into the sixteen (16) drive trays that
come with the subsystem. The drive trays, which must be installed in the
drive bays, accommodate SATA-II hard drives (backward compatible to
SATA-I).
Two (2) redundant, dual-fan cooling modules protect the subsystem from
overheating and two (2) redundant, hot-swappable, 2U 530W power supply
units (PSUs) provide constant power to the subsystem. The modular nature
