Compute Module

This chapter describes the function and physical components of the compute module. It
also describes the possible system configurations and the technical specifications for this
module. Specifically, this chapter includes the following information.
• "System Features" on page 108
• "External Components" on page 122
• "System Configuration" on page 126
• "Technical Specifications" on page 130
Two types of compute modules are available for the SGI 350 server system, as follows:
• Base compute module. This module is your system's primary compute module
where your server system's operating system resides. (Every system must have a
base compute module.) The base compute module provides processors, memory,
and PCI/PCI-X slots to connect I/O devices. It also comes standard with a
factory-installed SCSI disk drive, and an IO9 card and a serial daughtercard that
provide various I/O ports to your system.
• System expansion compute module. This module, in contrast to the base compute
module, comes with processors, memory, and PCI/PCI-X slots, but the SCSI disk
drive and the IO9 card are optional.
Note: In this chapter, the term "compute module" refers to both types of compute
modules, so remember that some of the features that are standard for the base compute
module are optional for the system expansion compute module. When information is
applicable to only one of the two types of modules, that will be specified.
