1.1.2.5 Rear Panel Overview

The enclosure rear view is shown below. The rear panel provides
access to all enclosure components. A description of each rear panel
component is given below:

Enclosure Rear View

˙

RAID controller module: The RAID controller module manages

all functionalities provided with the system, and all interface
connectors are provided on the controller faceplate.

˙

CBM module (optional feature; located within the RAID

controller module if installed): A CBM (Cache Backup Module)

is optional for the single-controller Galaxy RAID. The CBM
consists of a BBU (Battery Backup Unit) and FBM (Flash Backup
Module). The BBU sustains unfinished writes cached in memory
and cached data is distributed to the FBM in the event of a power
outage in order to prevent data loss.

˙

PSUs: Two (2) hot-swappable PSUs supply power to the

subsystem. Power on/off is controlled by the individual power
switches on the power supplies.

˙

Cooling Modules: Two (2) redundant cooling modules ventilate

the system to maintain a cooling airflow across the system.

1.1.2.6 Backplane Board

An internal backplane board separates the front and rear sections of
the enclosure. The backplane consists of traces for logic level signals
and low voltage power paths. It contains no user-serviceable
components.
