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 and PA-8900 is based on a different chip set (sx1000 or sx2000) than
Superdome with PA-8600 or PA-8700. For more information on the sx1000 and sx2000 chip sets, please refer to:

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 Universal Rack 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 (utilizing the Universal Rack). 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 is 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-8800 and PA-8900 processors (dual core per processor):
Superdome 32 processor cores: single cabinet (a left cabinet)
Superdome 64 processor cores: single cabinet (a left cabinet)
Superdome 128 processor cores: dual cabinet (a left cabinet and a right cabinet)
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. The base configuration
product numbers for each of the models are as follows:
