Compute Module

007-4566-001
The compute module is a 2U AC-powered device that consists of the following:
• Two or four 64-bit MIPS RISC processors.
• 4 MB of secondary cache per processor.
• 1 GB to 8 GB of memory.
• Zero to four PCI/PCI-X cards.
Note: The base compute module comes factory-installed with a PCI IO9 card in the
lowermost PCI/PCI-X slot.
• One or two sled-mounted Ultra3 SCSI disk drives (optional component of the
expansion compute module).
• DVD-ROM (optional).
The SCSI disk drives and the DVD-ROM require an IO9 PCI card.
Note: A compute module is not limited to two disk drives or four PCI/PCI-X slots. The
compute module can connect to external devices that expand the I/O and storage
capabilities. For information about these devices, see "PCI Expansion Devices" on
page 87.
Each compute module also contains an L1 controller that provides the following services:
• Controls and sequences power.
• Controls and monitors the environment.
• Initiates a reset.
• Stores identification and configuration information.
