Galaxy GHDX4 RAID iSCSI-SAS/SATA InstaHardware Reference Manual
13
This subsystem features a high-density architecture that supports hot
swappable SAS or SATA-II hard drives. The subsystem is powered
by active-active or a single RAID controller featuring the latest
ASIC667 RAID engine. The pre-installed 2GB DDR-II RAM DIMM
module can be upgraded to a 4GB capacity DIMM.
In addition to the ease of implementation, the iSCSI version of the
Galaxy also supports capacity expansion via its SAS links by
attaching JBODs.
The Galaxy features high-availability design with dual-active RAID
controllers. Dual-redundant, hot-swappable cooling modules, battery
backup, and power supplies ensures the optimal up time. The
modular nature of the subsystem and the easy accessibility to all
components ensure the ease of maintenance.
