1.1.3 Enclosure Chassis
1.1.3.1 Chassis Overview
The Galaxy RAID subsystem comes in a 2U metal chassis. A backplane board
divides the enclosure internally into front and rear sections. The front section
accommodates twelve (12) or eight (8) drive trays (with their associated hard drives)
and the rear section accommodates two (2) PSU modules, two (2) or three (3) single-
fan cooling modules, and a single RAID controller module. The two (2) forearm
handles on the front of the subsystem enable you to easily insert/extract the chassis
into/from a rack or cabinet. Pre-drilled mounting holes on the sides of the chassis
allow you to attach separately purchased slide rails.
