Crossbar Backplane
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-socket Superdome (16-way PA 8600/PA
8700 or 32 way PA 8800 ). Similarly, a backplane supporting eight cells would result in a 32-socket
Superdome (32-way PA 8600/PA 8700 or 64-way PA 8800). Two backplanes can be linked together
with flex cables to produce a cabinet that can support up to 16 cells resulting in a 64-socket Superdome
(64-way PA 8600/PA-8700 or 128-way PA 8800 128 way).

Each I/O chassis provides twelve I/O slots. Superdome PA-8600 and Superdome PA-8700 support I/O
chassis with 12 PCI 66 capable slots, eight PCI 2x, supported via single (1x) ropes (266 MB/s peak) and
four PCI 4x, supported via dual (1x) ropes (533 MB/s peak). Superdome PA-8600 and PA-8700 systems
support PCI I/O chassis only. Superdome PA-8800 supports I/O chassis with 12 PCI-X 133 capable
slots, eight PCI 4x, supported via single enhanced (2x) ropes (533 MB/s peak) and four PCI-X supported
via dual enhanced (2x) ropes (1066 MB/s peak). Superdome PA-8800 will be shipped with PCI-X I/O
chassis, but supports both PCI and PCI-X I/O chassis for in-field upgrades.
Each Superdome cabinet supports a maximum of four I/O chassis. The optional I/O expansion cabinet
can support up to six I/O chassis.
A 4 cell Superdome (16 socket) supports up to four I/O chassis for a maximum of 48 PCI X slots.
An 8 cell Superdome (32 socket) 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 socket) 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).

Core I/O
The core I/O in Superdome provides the base set of I/O functions required by every Superdome
partition. Each partition must have at least one core I/O card in order to boot. Multiple core I/O cards
may be present within a partition (one core I/O card is supported per I/O backplane); however, only
one may be active at a time. Core I/O will utilize the standard long card PCI-X form factor but will add a
second card cage connection to the I/O backplane for additional non-PCI X signals (USB and utilities).
This secondary connector will not impede the ability to support standard PCI-X cards in the core slot
when a core I/O card is not installed.
Any I/O chassis can support a Core I/O card that is required for each independent partition. A system
configured with 16 cells, each with its own I/O chassis and core I/O card could support up to 16
independent partitions. Note that cells can be configured without I/O chassis attached, but I/O chassis
cannot be configured in the system unless attached to a cell.
