The population rules for adding DIMMs to the server are as follows:
The storage server supports only 16-GB dual-rank (DR) Registered DIMMs (RDIMMs), labeled 2Rx4. Do not attempt to install any other DIMM sizes in the storage server.
Within each memory channel (four per processor), populate only the black DIMM socket with a DIMM.
Each processor supports four 16-GB DIMMs, for a maximum of 128 GB of memory.
