Two DCUs associated with each PDomain
PDomains on one or two servers, with one of these configurations:
On a single compute server, with the two PDomains within that compute server, each with two DCUs
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
Because there are two DCUs associated with each PDomain in an extended configuration, the PDomain in an extended configuration is considered a nonbounded PDomain. See PDomains Overview for more information on the characteristics of this type of PDomain.
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.
The following figure illustrates the available extended configurations.
