U2 – Two-CMIOU Domain Configurations
This diagram provides information on the available domain configurations for PDomains with two CMIOUs.
The specific CMIOU number varies, depending on the PDomain and SuperCluster model as shown in this table.
|
Also see Two CMIOU PCIe Card Configurations (SuperCluster M8) and Two CMIOUs PCIe Card Configurations (SuperCluster M7).
From an overall PDomain level, the configuration with two CMIOUs has the following characteristics:
-
Two processors (one processor per CMIOU), each processor with 32 cores (8 hardware threads per core), for a total of 64 cores
-
32 DIMM slots (16 DIMM slots per CMIOU), providing:
-
SuperCluster M8 – A total of 2 TB (64 GB DIMMs) of total memory, 1.9 TB available after DIMM sparing
-
SuperCluster M7 – A total of 1 TB (32 GB DIMMs) of total memory, 960 GB available after DiMM sparing
-
-
Two IB HCAs and two 10GbE NICs (one in each CMIOU) available for each PDomain
-
One 1GbE NIC available for each PDomain, installed in the lowest-numbered CMIOU in that PDomain
How these resources are divided between domains within this PDomain depends on the type of domain configuration you choose.
