1.1.1 Introduction
This hardware manual briefly introduces the Galaxy® HDX4 SAS to
SAS / SATA RAID subsystem. The 12-bay model comes with two (2)
6Gb/s SAS host channels and supports twelve (12) hot-swappable
6Gb/s SAS or 3Gb/s SATA hard drives in a 2U chassis. The core of
the subsystem is the RAID controller module powered by a 6th-
generation ASIC667
RAID engine. By default,
each RAID controller
comes with
a pre-
installed
1GB
DDRII
RAM DIMM
module.
Each SAS channel is
capable of a 2400MB/s bandwidth. With a passive backplane,
redundant hot-swappable component design, and sophisticated
firmware, the subsystem is ideal for high availability applications.
The enclosure is designed to contain twelve (12) 3.5-inch disk drives.
Drive capacity can be expanded by attaching a maximum of six (6)
2U-profile expansion drive enclosures, adding 72 more disk drives.
Two (2) cooling modules protect the subsystem from overheating,
and two (2) hot-swappable power supply unit (PSU) modules provide
constant power to the subsystem. The modular nature of the
subsystem and the easy accessibility to all major components ensure
ease of maintenance.
