Cells
(Processors and
Memory)
A cell, or cell board, is the basic building block of a Superdome system. It is a symmetric multi processor
(SMP), containing up to four processor modules and up to 16 GB of main memory using 512-MB
DIMMs (sx1000 only) in 32 memory slots, up to 32 GB of main memory using 1 GB DIMMs, up to 64
GB of main memory using 2 GB DIMMs, and up to 128 GB of main memory using 4-GB DIMMS
(sx2000 only). It is also possible to mix DIMM sizes on the same cell board. A connection to a 12 slot
PCI X card cage is optional for each cell. Each hard partition must be connected to at least one PCI-X
I/O card cage.
The Superdome cell boards shipped from the factory are offered with 1, 2, 3, or 4 processors.
The Superdome cell board contains:
sx2000: Intel Itanium 9000 or 9100 series processor modules (up to 4 processor modules for a
total of 8 cores) or Itanium 1.6 GHz processors (up to 4 processor modules for a total of 4 cores)
Cell controller ASIC (application specific integrated circuit)
Main memory DIMMs installed in groups of eight
Voltage Regulator Modules (VRM)
Data buses
Optional link to 12 PCI X I/O slots

Crossbar Backplane
sx2000: Each backplane contains three independent crossbar fabrics resulting in a robust highly
available system. A High speed serial (HSS) link technology is employed for crossbars interconnect. Each
backplane cabinet can support up to eight cells. Eight cells support a 32 processor module Superdome.
Two backplanes (two cabinets) can be linked together with flex cables to produce a complex that can
support up to 16 cells resulting in a 64 processor module Superdome (128 core dual core Itanium or 64
core Itanium (Mad9M)).
sx1000: 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. A backplane supporting four cells results in a 16 processor Superdome (16 core Itanium
Madison or 32 core Itanium mx2). Similarly, a backplane supporting eight cells would result in a 32
processor Superdome (32 core Itanium Madison or 64 core Itanium mx2). Two backplanes can be
linked together with flex cables to produce a cabinet that can support up to 16 cells resulting in a 64
processor Superdome (64 core Itanium Madison or 128 core Itanium mx2).

I/O Subsystem
Each I/O chassis provides twelve I/O slots.
Sx2000: The sx2000 Superdome supports I/O chassis with two PCI-X 266 MHz slots, six PCI-X 133MHz
slots and 4 PCI -X 66 MHz slots. These I/O chassis employ a PCI-X bus for each I/O slot. PCI-X mode 2
is supported.
Each Superdome cabinet supports a maximum of four I/O chassis. The optional I/O expansion
cabinet can support up to an additional six I/O chassis
A 4 cell Superdome (16 processor) supports up to four I/O chassis for a maximum of 48 PCI X
slots.
An 8 cell Superdome (32 processor) supports up to eight I/O chassis for a maximum of 96 PCI X
slots. Four of these I/O chassis will reside in an I/O expansion cabinet.
A 16 cell Superdome (64 processor) supports up to sixteen I/O chassis for a maximum of 192 PCI
X slots. Eight of these I/O chassis will reside in two I/O expansion cabinets (either six chassis in
one I/O expansion cabinet and two chassis in the other, or four chassis in each).
