System memory guidelines

The VxRail P670F, P670N, V670F, and S670 support DDR4 registered DIMMs (RDIMMs), Load Reduced DIMM (LRDIMMs), and Intel Persistent Memory 200 series (BPS). System memory holds the instructions that the processor starts.

Your system memory is organized into eight channels per processor (two memory sockets per channel),16 memory sockets per processor, and 32 memory sockets per system.

The following figure shows the memory channels:
