VMware vSphere 6.7 – Virtual Machine vCPU and vNUMA Rightsizing

VMware vSphere 6.7 – larger and more demanding workloads like databases on top of the latest generations of processors with up to 24 cores special care must be taken in vCPU and vNUMA configuration to ensure performance is optimized

This table outlines how a virtual machine should be configured on a dual socket 10 core physical host to ensure an optimal vNUMA topology and performance regardless of vSphere version where the assigned memory is less than or equal to a pNUMA node
