From an overall PDomain level, the extended configuration PDomains with half-populated DCUs have the following resources:
Two DCUs, with two CMUs in each DCU, for a total of four CMUs
Eight processors (two processors per CMU)
256 DIMM slots (64 DIMM slots per CMU), for a total of 4 TB (16 GB DIMMs) or 8 TB (32 GB DIMMs) of total available memory
Eight IB HCAs
How these resources are divided between LDoms within this PDomain depends on the type of LDom configuration you choose.
