SPs and SPPs
The two redundant SPs enable you to actively manage and monitor the components
in the server independent of the Oracle Solaris OS. The four SPPs off-load some of
the work from the two SPs. The SPs and SPPs work together to provide a single
management environment to all of the server components.
See “Front Components” on page 6 for the location of the SPs, and see “Rear
Components” on page 8 for the location of the SPPs.

Domain Configurable Units
Domain configurable units (DCUs) are the hardware building blocks of PDomains. A
DCU includes one IOU, which contains internal drives, network connections through
the EMS modules, and 16 PCIe expansion slots. A DCU also contains 2 or 4 CMUs,
and each CMU contains 2 processors and 2 memory boards. The following
illustrations display the locations and components of DCUs.
