Product Introduction

This hardware manual briefly introduces the Galaxy GHDX2-2430S-16U4D
SCSI-320 to SATA-II storage subsystem shown in Figure 1-1. The
GALAXY subsystem comes with two (2) 320MB/second SCSI (SCSI-320)
host channels. This high-density subsystem supports up to sixteen (16)
SATA-II hard drives in a 3U profile chassis. The subsystem is managed by a
RAID
powered by the ASIC400 XOR
engine
RAID6
subsystem comes with a pre-
installed 256MB DDR RAM
DIMM module that can be
replaced by one with the 2GB capacity. The SCSI-320 host channels feature
packet protocols with reduced command overhead and provide increased
transfer speed and abundant bandwidth.
The subsystem is equipped with a dedicated hardware XOR for RAID6
acceleration. A RAID6 array configuration allows two (2) disk drive failures
to occur at the same time. This feature marks a giant step forward for
providing a higher level of data integrity. RAID level 6 and the
combinations of striped RAID6 arrays (RAID60) are both supported.
Two (2) dual-stacked VHDCI SCSI connectors connect the subsystem to
host computers and/or cascaded subsystems. Two (2) redundant cooling
modules provide cooling airflow within the subsystem. Two (2) redundant
and hot-swappable power supply unit (PSU) modules provide constant
power to the subsystem. A battery backup unit (BBU) is accessible and hot-
swappable through the rear panel. The modular design of the subsystem
provides the ease of access to all major modules and hence reduces the
maintenance efforts.
On receiving and unpacking your subsystem, please check the package
contents against the included Unpacking List. If any modules appear to be
damaged or missing, please contact your subsystem vendor immediately.
