The Enclosure Core Product

The SR1202 design concept is based on an enclosure subsystem together with a set of plugin modules.

The SR1202 Enclosure Platform as supplied comprises:

• Chassis and Backplane with integral (front panel mounted) Operator’s Panel (see Figure 11)

• Up to 12 Drive Carrier Modules (see Figure 21), containing either:

– 3.0 Gb/s direct dock SAS disk drives,

– 3.0 Gb/s direct dock SATA disk drives, or

– 3.0 Gb/s dual path SATA disk drives via an active/active SATA mux transition card

• Two plug-in Power Supply Modules,100–260 V AC, 350 W (see Figure 14)

• One plug-in Cooling Fan Module

• Two plug-in SR1202 RAID Controller Modules (see Figure 17), incorporating a SR1202 RAID

Controller and a StorView

Management Module.

 NOTE

If only one SR1202 RAID Controller Module is installed then a Blank (SR1202) module must be fitted

in the unused slot.

Enclosure Chassis

The chassis consists of a sheet metal enclosure assembly containing a Backplane printed circuit board

(PCB) and module runner system.

• The chassis front panel incorporates an integral Operator’s (Ops) Panel.

• The Backplane PCB provides logic level signal and low voltage power distribution paths.

• Figure 11 and Figure 12 show front and rear views of a populated chassis respectively.

• The chassis is fitted with 19 inch Rack mounting features which enable it to be fitted to

standard 19 inch racks and uses 2 EIA units of rack space (i.e. 3.5” high).

The chassis assembly contains 12 drive bays at the front, each of which accommodates the appropriate

plug-in drive carrier module. The 12 drive bays are arranged in 3 rows of 4 drives. At the rear, the

chassis assembly contains four plug-in module bays to house two Power Supply modules, a Cooling

Fan module and two SR1202 RAID Controller Modules which are fitted horizontally (one above the

other) in the fourth bay, as shown in Figure 12

 NOTE

A drive bay is defined as the space required to house a single 1.0“ high 3.5 inch disk drive in its carrier

module. e.g. a 1 x 3 bay module would take the space of 1 drive width by 3 drive bays high (in rack

mount configuration), shown in Figure 11.
