CPU Module (CMOD) Overview
CPU Module (CMOD) Overview
CPU modules (CMODs) contain the processors (CPUs) and the system memory, and supply
power to the fan modules and the DPCCs.
CMODs are internal warm or cold-service components. To access the CMODs, you must
remove the fan modules and the fan frames.
The following sections describe the CMOD configuration options and the internal layout of
components:

Processor and Memory Overview
Each CMOD contains one Intel Xeon E7-8895 v2 15-Core, 2.8 GHz processor.
The server CMODs contain the system memory. The maximum system memory depends on the
number of CMODs in the server. For a four-CMOD system, the maximum memory (DDR-1333
32 GB DIMMs) is 3 TB, and for an eight CMOD system, the maximum memory (DDR-1333
32 GB DIMMs) is 6 TB.
CMOD Configuration Options
The server supports two CMOD configurations, a four-CMOD and eight-CMOD configuration.
In the four-CMOD configuration, the first four slots on the left (slots 0-3) are occupied and the
four slots on the right (4-7) are unoccupied.
The following illustration shows a server with a four-CMOD configuration. In the illustration,
the left side fan modules and fan frame have been removed to show the four CMODs. Call out 1
identifies the group of four CMODs.
