Partitioning enables arbitrary assignment of resources in the server. Partitioning also
enables flexible domain configurations to be used according to the job load or
processing amount.
An independent Oracle Solaris OS can run in a domain. Each domain is protected by
hardware so that it is not affected by other domains. For example, a software-based
problem, such as an OS panic, in one domain does not directly affect jobs in the
other domains. Furthermore, the Oracle Solaris OS in each domain can be reset and
shut down independently.
2.2.2 Domain Hardware Requirements
The basic hardware resources making up a domain are a CMU and an IOU mounted
in the high-end servers or a physical system board (PSB) consisting of a CMU.
A PSB can be logically divided into one part (no division) or four parts. The physical
unit configuration of each divided part of a PSB is called an extended system board
(XSB).
A PSB that is logically divided into one part (no division) is called a Uni-XSB, and a
PSB that is logically divided into four parts is called a Quad-XSB.
A domain can be configured with any combination of these XSBs. The XSCF is used
to configure a domain and specify the PSB division type.
Note – Although a CMU with two CPUMs can be configured into Quad-XSB mode
on an M8000/M9000 server, the server generates a "configuration error" message for
those XSBs that do not have a CPUM and memory.
