U4 – Four-CMIOU Domain Configurations
This diagram provides information on the available domain configurations for PDomains with four CMIOUs.
The specific CMIOU number varies, depending on which PDomain is being used as shown in this table.

Also see Four CMIOUs PCIe Card Configurations.
From an overall PDomain level, the configuration with four CMIOUs has the following characteristics:
-
Four processors (one processor per CMIOU), each processor with 32 cores (8 hardware threads per core), for a total of 128 cores
-
64 DIMM slots (16 DIMM slots per CMIOU), providing:
-
SuperCluster M8 – A total of 4 TB (64 GB DIMMs) of total memory, 3.84 TB after DIMM sparing
-
SuperCluster M8 – A total of 2 TB (32 GB DIMMs) of total memory, 1.92 TB after DIMM sparing
-
-
Four IB HCAs and four 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.
