Warning:
To prevent personal injury or damage to your system, only trained SGI
system support engineers (SSEs) can service or configure internal components of the
compute module that are not specifically listed as serviceable and configurable by
customers.
The base compute module can be configured with the following optional items to expand
its function:
• The system expansion compute module, which is interconnected to the base
compute module via a NUMAlink 3 cable, adds processors, memory, and four
PCI/PCI-X card slots. It may or may not include an IO9 card. (The combination of
the base compute module with the system expansion compute module can create a
single system that includes 4, 6, or 8 processors, with up to 16 GB of local memory,
and seven PCI/PCI-X card slots.)
• The 4U PCI expansion module adds PCI slots, but no processors, no memory, and
no IO9 card. There are two versions of the PCI expansion module: one module has
12 PCI slots that support 3.3-V or universal PCI cards, and the other module has 6
PCI slots that support 5-V or universal PCI cards and 6 slots that support 3.3-V or
universal PCI cards. For more information about this module, see PCI Expansion
Module User's Guide (5.0-V Support and/or 3.3-V Support) (007-4499-00x).
• The 2U memory and PCI expansion (MPX) module can provide extra memory and
four PCI/PCI-X card slots to your system. See Chapter 4, "Memory and PCI
Expansion (MPX) Module," for more information about this module.
• The TP900 storage module provides additional storage to the system. See SGI Total
Performance 900 Storage System User's Guide, 007-4428-00x, for information about this
module. The Origin 350 server system supports other storage modules. See "Storage
Expansion" on page 89 for information.
• The NUMAlink module connects two or more compute modules. See Chapter 5,
"NUMAlink Module," for more information about this module.
The Origin 350 server system can be configured in many different ways to satisfy your
computing needs. This section shows two sample configurations.
