Table A-2 lists the bandwidth characteristics of the compute module.
Table A-2 Bandwidth Characteristics of the Compute Module
Characteristic Peak Bandwidth
NUMAlink 3.2 GB/s full duplex
channel
1.6 GB/s each direction
Xtown2 channel 2.4 GB/s full duplex
1.2 GB/s each direction
Main memory 3200 MB/s
SYSAD 1600 MB/s
Table A-3 summarizes the general features of the compute module.
Note: The following table assumes that the expansion compute module does not include
an optional IO9 PCI card, which would add one input and one output real-time interrupt
port, an Ethernet port, and an internal and external SCSI drive, and support for one serial
port. The IO9 card is also needed to support the DVD-ROM, the SCSI disc drives, and the
serial daughtercard with the PS/2 connectors and three serial ports (this serial
daughtercard is not an option for the expansion compute module).
