SPARC M8-8 - Version All Versions and later
Information in this document applies to any platform.
The SPARC M8-8 and M7-8 servers can be ordered with one or two PDomains.
A server with one PDomain includes all of the processors, memory, and PCIe expansion in the chassis. In this configuration, the server can use up to eight processors within its single static PDomain.
In a server with two PDomains, each PDomain includes half of the possible processors, memory, and PCIe expansion slots in the chassis. In this two PDomain configuration, each static PDomain operates as a separate server within the same chassis.
The goal of this document is to demonstrate how to identify the two configurations of SPARC M8-8 and M7-8 servers.
Note : M8 Supercluster uses the SPARC M8-8 with two PDomains and the M7 Supercluster uses the SPARC M7-8 with two PDomains.
