1.1.3 Enclosure Chassis

1.1.3.1 Chassis Overview

The Galaxy 12 bay and 8 bay subsystems come in a 2U metal chassis. A backplane board

divides the enclosure internally into front and rear sections. (See Figure 1-3) 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.
