There are three basic building blocks in the Superdome system architecture: the cell, the crossbar backplane and the I/O subsystem. Please note that
Superdome with PA-8800 is based on a different chip set (sx1000) than Superdome with PA-8600 or PA-8700. For more information on the sx1000 chip set,
please refer to the

Cabinets
A Superdome system can consist of up to four different types of cabinet assemblies:
At least one Superdome left cabinet. 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 I/O cards. Systems may include both left
and right cabinet assemblies containing, a left or right backplane respectively.
One or more HP Rack System/E cabinets. These 19-inch rack cabinets are used to hold the system peripheral
devices such as disk drives.
Optionally, one or more I/O expansion cabinets (Rack System/E). An I/O expansion cabinet is required when a
customer requires more PCI cards than can be accommodated in their Superdome cabinets.
Superdome cabinets are serviced from the front and rear of the cabinet only. This enables customers to arrange the cabinets
of their Superdome system in the traditional row fashion found in most computer rooms. The width of the cabinet
accommodates moving it through common doorways in the U.S. and Europe. The intake air to the main (cell) card cage is
filtered. This filter can be removed for cleaning/replacement while the system is fully operational.
A status display will be 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.
For PA-8600 and PA-8700 processors (single core per processor):
Superdome 16-way: single cabinet (a left cabinet)
Superdome 32-way: single cabinet (a left cabinet)
Superdome 64 way: dual cabinet (a left cabinet and a right cabinet)
For PA-8800 processors (dual core per processor):
Superdome 32-way: single cabinet (a left cabinet)
Superdome 64-way: single cabinet (a left cabinet)
Superdome 128-way: dual cabinet (a left cabinet and a right cabinet)
Each cabinet may contain a specific number of cell boards (consisting of CPUs and memory) and I/O. See the following
sections for configuration rules pertaining to each cabinet. The base configuration product numbers for each of the models
are listed below.
