Superdome 64-way servers also can have optional I/O expansion
cabinet hardware.
The model string for Superdome 64-way servers is
9000/800/SD64000.
With HP’s Superdome servers you can start with a system that meets
your needs now, and add more components as your needs increase.
You can add components (cells and I/O chassis) to your existing system
as needs arise, and can also upgrade to larger-capacity systems as
needed. A Superdome 16-way server can be upgraded to a Superdome
32-way server, and likewise the Superdome 32-way server can be
upgraded to Superdome 64-way server.
You can add I/O expansion cabinets to a Superdome server at any time.
HP Superdome I/O Expansion Cabinet
HP Superdome 32-way and Superdome 64-way servers can include I/O
expansion cabinets in addition to the server cabinet(s) in the complex.
Each I/O expansion cabinet has a cabinet number of either 8 or 9.
A Superdome I/O expansion cabinet includes up to 3 I/O bays, with two
12-slot I/O chassis in each bay. This provides for up to 6 chassis with a
total of 72 PCI card slots in each I/O expansion cabinet.
Each I/O expansion cabinet has its own power supplies, fans, and
utilities (which are connected to the Superdome server’s service
processor bus).
The I/O chassis (and PCI card slots) within each I/O expansion cabinet
are made available to nPartitions through direct I/O chassis-to-cell
connections—exactly as internal Superdome server cabinet I/O chassis
are connected to cells.
Refer to the I/O Expansion Cabinet Guide for details.
