Bosch Security System

The front panel of the RAID subsystem enclosure houses sixteen (16) hard drives in a 4x4 con-

figuration as shown in Figure 2.5. When viewed from the front, the drive bays (slots) are num-

bered 1 to 16 from left to right, from top to bottom.

Hard Drive Numbering

The rear section of RAID subsystem is accessed through the rear panel and is reserved for a 

single RAID controller module, one (1) BBU, two (2) power supply units (PSUs) and two (2) 

cooling modules.

The rear panel of the RAID subsystem described in this manual is shown in Figure 2.6. A 

description of each rear panel component is given below:

RAID subsystem Rear View 

The rear panel shown in Figure 2.6 accommodates the following components: 

•

RAID controller module: A controller board and a DDR RAM DIMM module are housed in 

the controller module to provide the system RAID functionalities. (See Section 2.5.3 The 

RAID Controller Module)

•

BBU: A BBU sustains cache memory during a power shortage to prevent data loss. (See 

Section 2.5.6 Battery Backup Unit (BBU))

•

PSUs: The hot-swappable PSUs provide power to the subsystem. A power switch is 

located on the right of each PSU to turn the system on and off. (See Section 2.5.7 Power 

Supply Units)

•

Cooling modules: The redundant cooling modules ventilate the subsystem to reduce the 

temperature within the subsystem. (See Section 2.5.8 Cooling Modules)

•

Dummy plate: This device is a single controller subsystem. The only controller module is 

installed in the upper controller bay. A dummy plate covers the lower controller bay at 

the rear of the subsystem.

Internal backplane boards separate the front and rear sections of the RAID subsystem. The 

PCB board provide logic level signals and low voltage power paths. They contain no user-ser-

viceable components.
