Two DCUs associated with each PDomain
PDomains on one or two compute servers:
On a single compute server, with the two PDomains within that compute server, each with two DCUs, or
Split across two compute servers, with the two PDomains split across the two compute servers (one PDomain on each server), with each PDomain containing two DCUs
Note - Certain DCU configurations have a mixture of half-populated and fully-populated DCUs in a compute server. For extended configuration PDomains in those DCU configurations, both DCUs in each PDomain must have the same configuration, where both DCUs in the PDomain are either half-populated or fully-populated. See CMU Overview for more information.
Extended configuration PDomains are available for fully-populated DCUs and half-populated DCUs:
