The following rules apply when building a server configuration with eXFlash DIMMs:
The 200 GB and 400 GB eXFlash DIMMs cannot be mixed.
Performance memory mode must be selected. RAS (lockstep) memory mode is not supported.
Only RDIMMs are supported by eXFlash DIMMs; LRDIMMs are not supported
eXFlash DIMMs can only installed on the Compute Books in the lower half of the server (processors
1-4)
The maximum quantities of eXFlash DIMMs are as follows:
Four processors: 16 eXFlash DIMMs
o
Six processors: 24 eXFlash DIMMs
o
Eight processors: 32 eXFlash DIMMs
