1.2 The Enclosure Core Product
The Altos S205F / S200F Storage System design concept is based on a subsystem together with a set
of plug-in modules. The Altos S205F / S200F Storage System subsystem as supplied comprises:
• Chassis and Backplane with integral Operators Panel.(See Figure 1–11 )
• Up to 16 Serial ATA (SATA) Drive Carrier modules (See Figure 1–12 )
– Serial ATA (SATA) drives with appropriate switching card.
• Dummy drive carrier modules.
• Two plug-in Power Supply/Cooling modules:
– AC, 450W PSU (See Figure 1–7 )
• Either one or two I/O Modules:
– For Altos S205F - single or dual RAID I/O Modules(See Figure 1–9 )
– For Altos S200F - single or dual JBOD I/O Modules (See Figure 1–10 ).
• Blank I/O module.
1.2.1 Enclosure Chassis
The chassis consists of a sheet metal enclosure assembly containing a Backplane printed circuit
board (PCB) and module runner system. This chassis assembly also includes an integral Operators
(Ops) Panel, mounted at the rear.
The chassis assembly contains 16 drive bays at the front, each of which accommodates a plug-in
drive carrier module. The 16 drive bays are arranged in 4 rows of 4 drives. At the rear, the chassis
assembly contains the integral ops panel module and four plug-in module bays to house two Power
Supply/Cooling modules and two Controller I/O modules.
The Backplane PCB provides logic level signal and low voltage power distribution paths. Figure 1–
2 and Figure 1–3 show front and rear views of an Altos S205F Storage System chassis. Figure 1–4 and
Figure 1–5 show front and rear views of an Altos S200F Storage System chassis.
The chassis is fitted with 19 inch Rack mounting features which enables it to be fitted to standard
19 inch racks and uses 3EIA units of rack space.
• A 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 4 bay module would take the space of 1 drive width by 4 drive bays high (in
rack mount configuration).
• A 4 x 4 Chassis fitted with 19 inch Rack mounting features enables it to be fitted to standard
19 inch racks. It uses 3EIA units of rack space
