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
-
CMIOU_0 – CMIOU_2
-
CMIOU_0 – CMIOU_3
-
CMIOU_0 – CMIOU_4
-
CMIOU_0 – CMIOU_5
-
CMIOU_0 – CMIOU_6
-
CMIOU_0 – CMIOU_7
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.
 | Caution - To prevent overheating, fill unused CMIOU slots with CMIOU filler panels. |
