CMIOU Configurations (SPARC M8-8 and SPARC M7-8 With One PDomain)

A SPARC M8-8 and SPARC M7-8 server that is configured as a single PDomain can have as many as eight CMIOUs in a single CMIOU chassis, as listed in the following table.

The following configurations are supported on a SPARC M8-8 and SPARC M7-8 server that has one PDomain.

  • CMIOU_0 and CMIOU_1







Note -  The SPARC M7-8 server with one PDomain does not support SPARC M8 CMIOUs. SPARC M7 CMIOUs are not supported in SPARC M8-8 servers. See Mixed CMIOU Configurations for more information.

For information about the PCIe slots that are available in each of these configurations, see Understanding PCIe Card Device and Service Paths.
