The CPU modules (CMODs) are the processing engines for the Sun Server X2-8. Each CMOD contains two processors (CPUs), memory, and I/O capabilities for PCIe and GigabitEthernet.
The CMOD bay of the Sun Server X2-8 can contain up to four CMODs. The server supports two configurations, a two-module configuration and a fully loaded four-module configuration. In both configurations, CMOD 0 (BL 0) is the master CMOD. In the two-module configuration, a filler module must be used for slots that do not contain a CMOD. CMODs and filler modules have a lever mechanism that is used for removal and installation. The lever is held in place by a locking latch.
Note - CMODs and CPU filler modules are designated as customer-replaceable units (CRU).
