We are running VMware on BL660s with 4 sockets/8 cores, 512 GB of RAM with ESX 5.5 running 1 SQL Server environment. Questions:
1. How does VMware handle Hyper-threading in relation to NUMA?
2. What would be a proper breakout of CPUs to match the hardware NUMA? VMware suggested that you should not account for hyper-threading when determining your CPU/Core configuration in the VM, hence, do not exceed 32 cores. Based on the above, we were thinking just assigning the 4 socket/8 core to the VM, but VMware says we should leave physical cores aside for the hyper-visor to manage the resources. So we are down to 4 sockets/6 or 7 cores to stay within the hardware NUMA?
