NUMA

  1. Create a RAID out of drives belonging to the same NUMA node, if your systems are multiprocessor.

    To figure out the NUMA node drive, run:

    # cat /sys/block/nvme0n1/device/device/numa_node

    or via lspci:

    # lspci -vvv

  2. At creation of NVMe-oF target for xiRAID Classic RAID, you can use network adapter of the same NUMA node as NVMe drives.
