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 v3 (18-core 2.6 GHz) processor.
The maximum system memory with DDR3 1333 32 GB DIMMs is:
■
Four CMODs: 3 TB
■
Eight CMODs: 6TB
CMOD Configuration Options
The server supports four- and eight-CMOD configurations. 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.
