Configuration
There are three basic building blocks in the Superdome system architecture: the cell, the crossbar backplane and the PCI X based I/O subsystem.

Cells (CPUs and Memory) A cell, or cell board, is the basic building block of a Superdome system. It is a symmetric multi processor (SMP), containing

Starting with the sx1000 chip set, Superdome servers will be released with the Graphite color. A Superdome system will
consist of up to four different types of cabinet assemblies:
One Superdome left cabinet.
No more than one Superdome right cabinet (only Superdome 64-way 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 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 X cards than can be accommodated in their Superdome cabinets.
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 will be removable 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.
Superdome 16-way and Superdome 32-way systems are available in single cabinets. Superdome 64 way systems are
available in dual cabinets.
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.
up to 4 processor modules and up to 16 GB of main memory using 512 MB DIMMs or up to 32 GB of main memory using
1 GB DIMMs. It is also possible to mix 512 MB and 1 GB DIMMs on the same cell board. A connection to a 12 slot PCI X
card cage is optional for each cell.
The Superdome cell boards shipped from the factory are offered with 2 processors or 4 processors. These cell boards are
different from those that were used in the previous releases of Superdome.
The cell boards can contain a minimum of 2 (for 2-way cell boards) and 4 (for 4-way cell boards) active processors.
The Superdome cell board contains:
Itanium 2 1.5-GHz CPUs (up to 4 processor modules)
Cell controller ASIC (application specific integrated circuit)
Main memory DIMMs (up to 32 DIMMs per board in 4 DIMM increments, using 512 MB or 1 GB DIMMs - or some
combination of both.)
Voltage Regulator Modules (VRM)
Data buses
Optional link to 12 PCI X I/O slots
Each crossbar backplane contains two sets of two crossbar chips that provide a non blocking connection between eight
cells and the other backplane. Each backplane cabinet can support up to eight cells or 32 processors (in a Superdome 32-
way in a single cabinet). A backplane supporting four cells or 16 processors would result in a Superdome 16-way. Two
backplanes can be linked together with flex cables to produce a cabinet that can support up to 16 cells or 64 processors
(Superdome 64-way in dual cabinets).
