Each PDomain in a SPARC M8-8 and SPARC M7-8 server that is configured with two static PDomains can consist of up to four of the eight CMIOUs in the chassis.
The following configurations are supported on a SPARC M8-8 and SPARC M7-8 server that has two PDomains.
CMIOU_0 and CMIOU_1 in PDomain_0 and
CMIOU_4 and CMIOU_5 in PDomain_1
CMIOU_0 – CMIOU_2 in PDomain_0 and
CMIOU_4 – CMIOU_6 in PDomain_1
CMIOU_0 – CMIOU_3 in PDomain_0 and
CMIOU_4 – CMIOU_7 in PDomain_1
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.
