QuickSpecs

Configuration

There are three basic building blocks in the Superdome system architecture: the cell, the crossbar backplane, and the PCI X (or

PCIeX) based I/O subsystem. Below is a high level illustration of this architecture. The figures below depict the system architecture:

Cabinets (sx2000)

Cabinets

Starting with the sx1000 chip set, Superdome servers have been released with the graphite color. A

Superdome system will consist of up to four different types of cabinet assemblies:

Superdome left cabinet (required)

Superdome right cabinet (only Superdome 64 processor system).

The Superdome cabinets contain all of the processors, memory and core devices of the system.

They will also house most (usually all) of the system's PCI X cards. Systems may include both left

and right cabinet assemblies containing, a left or right backplane respectively.

One or more HP 10K G2 Universal Rack cabinets (required). These 19 inch rack cabinets are

used to hold the system peripheral devices such as disk drives and DVD.

Optionally, one or more I/O expansion cabinets (HP 10K G2 Universal Rack only). An I/O

expansion cabinet is required when a customer requires more I/O cards than can be

accommodated in their Superdome cabinets. Superdome I/O expansion cabinets require a special

I/O Expansion Power and Utilities Subsystem (A5861D).

Superdome cabinets will be serviced from the front and rear of the cabinet only. This will enable

customers to arrange the cabinets of their Superdome system in the traditional row fashion found in most

computer rooms. The width of the cabinet will accommodate moving it through common doorways in the

U.S. and Europe. The intake air to the main (cell) card cage will be filtered. This filter is removable for

cleaning/replacement while the system is fully operational.

A status display is located on the outside of the front and rear doors of each cabinet. The customer and

field engineers can therefore determine basic status of each cabinet without opening any cabinet doors.

Superdome 16 processor and Superdome 32 processor systems are available in single cabinets.

Superdome 64 processor systems are available in dual cabinets.

Each cabinet may contain a specific number of cell boards (consisting of processors and memory) and

I/O. See the following sections for configuration rules pertaining to each cabinet.
