SPARC M8 and SPARC M7 Servers Installation Guide

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.
