You can perform resource management with different types of NUMA architecture.

With the proliferation of highly multicore systems, NUMA architectures are becoming more popular as these architectures allow better performance scaling of memory intensive workloads. All modern Intel and AMD systems have NUMA support built into the processors. Additionally, there are traditional NUMA systems like the IBM Enterprise X-Architecture that extend Intel and AMD processors with NUMA behavior with specialized chipset support.

Typically, you can use BIOS settings to enable and disable NUMA behavior. For example, in AMD Opteron-based HP Proliant servers, NUMA can be disabled by enabling node interleaving in the BIOS. If NUMA is enabled, the BIOS builds a system resource allocation table (SRAT) which ESXi uses to generate the NUMA information used in optimizations. For scheduling fairness, NUMA optimizations are not enabled for systems with too few cores per NUMA node or too few cores overall. You can modify the numa.rebalancecorestotal and numa.rebalancecoresnode options to change this behavior.
