1.1.1 Product Introduction
This hardware manual briefly introduces the AR3016G 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 AR3016G 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 AR3016G 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 AR3016G.
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
of the subsystem and the easy accessibility to all major components ensure
the ease of the subsystem maintenance.
