1.1.1 Product Introduction
This hardware manual briefly introduces the Galaxy Fibre-4G to SATA-II
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 GALAXY subsystem comes with single Fibre to SATA RAID
controller and provides two
(2) 4Gbps (FC-4G) host
channels. Two (2) onboard
SATA chips provide
sixteen (16) 3Gbps SATA-
II drive channels that can
support up to sixteen (16)
SATA-II hard drives. The controller board has a pre-installed 256MB DDR
RAM DIMM module and can support a memory module with a capacity up
to 2GB.
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 GALAXY 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 upper left side 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 the GALAXY.
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, hot-swappable, dual-fan cooling modules protect the
subsystem from overheating and two (2) redundant, hot-swappable, 2U
460W power supply units (PSUs) provide constant power to the subsystem.
