The population rules for adding DIMMs to the server are as follows:
The server supports four 16-GB dual-rank (DR) Registered DIMMs (RDIMMs) on Processor 0, and four 8-GB single-rank (SR) Registered DIMMs (RDIMMs) on Processor 1.
Within a memory channel, DIMMs must be populated in the black sockets. The storage server does not support DIMMs in the white sockets or the black sockets with white tabs.
