ESX, NUMA and "Node Interleaving"

Node interleaving disabled equals NUMA which is the best practice for ESX. That's usually default setting in BIOS of NUMA capable servers.

NUMA can be disabled by enabling Node Interleaving in the BIOS of the ESX host but that's not good practice for NUMA systems.
