SPARC M8-8 and SPARC M7-8 Servers DCUs
A SPARC M8-8 or SPARC M7-8 server factory-configured as one PDomain contains a
single DCU containing up to eight CMIOUs. A SPARC M8-8 or SPARC M7-8 server
factory-configured as two PDomains contains two DCUs, and each DCU contains up to
four CMIOUs. Each CMIOU contains 1 processor, 16 DIMM slots, and 3 PCIe expansion
slots.
While you cannot reconfigure the DCUs in SPARC M8-8 or SPARC M7-8 servers like you
can in SPARC M7-16 servers, you will see the DCU term in the Oracle ILOM user
interface and in system messages.
Each DCU can contain the following CMIOUs.

Note -
Both the SPARC M8-8 and SPARC M7-8 servers capable of two PDomains can contain
a DCU0 fully-populated with CMIOUs and an empty DCU1. In this configuration,
DCU1 would be available for future expansion.
