The factory-installed IO9 card provides the following connectors:
• Real-time interrupt input and output. RTO (output) enables the compute module
to interrupt an external device. RTI (input) enables an external device to interrupt
the compute module.
• Ethernet port (10/100/1000 Mbits). This autonegotiating
10BaseT/100BaseT/1000BaseT twisted-pair Ethernet port connects the compute
module to an Ethernet network.
• SCSI connector. This 68-pin VHDCI external SCSI port enables you to connect SCSI
devices to the compute module. For an updated list of supported SCSI devices, see
the SGI Supportfolio at http://support.sgi.com.
This section lists the internal compute module configuration options, such as the number
of DIMMs that can be installed in the compute module to increase its local memory.
This section also lists external compute module configuration options that can enhance
the performance of the Origin 350 server system. For example, the compute module can
connect to a 2U TP900 storage system to expand storage, or it can connect to a PCI
expansion module to increase I/O capabilities.
Processors, PCI and PCI-X cards, disk drives, and memory (DIMMs) are the configurable
internal components of the compute module.
Warning:
Of these configurable items, processors and the IO9 PCI card, can be
installed and removed only by trained SGI system support engineers (SSEs).
As a customer, you can configure PCI and PCI-X cards, disk drives, and memory. See
Chapter 4, "Installing and Removing Customer-replaceable Units," for information
about installing and removing these items to reconfigure your server module.
