The preceding table provides a non-exhaustive list of FRUs that reflects the common top-level assembly parts.
System memory
The VxRail supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System memory holds the
instructions that are executed by the processor.
NOTE:
MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following factors:
● DIMM type (RDIMM or LRDIMM)
● Number of DIMMs populated per channel
● System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
● Maximum supported DIMM frequency of the processors
Your VxRail contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is
organized into six channels. In each channel, the release tabs of the first socket are marked white, and the second socket black.
The following figure shows the memory socket locations:
The following table describes the memory channels and how the channels are organized:
