So, to recap my question to the experienced admins are the following:ġ. Specially considering that homeNode 3 is not used at all. Shall I set it to 44 as it is the max number of logical cores in a physical socket? Or shall I disable it and let the system do its best decision? If yes how do I disable it? This is the current layout of the cpu resources of the vm:Īlthough performances have improved I’m not happy with the distribution of the cores. This is another thing I don't understand.įollowing which criteria do I adjust value? According to Virtual NUMA Controls I should get 6 virtual nodes by dividing 64 by 11,but I see the VM has 7. I read the above after I did the initial changes to the VM and I have now noticed that its value is 11. This setting overrides the =TRUE setting” “Please remember to adjust the setting in the VM if it is already been powered-on once. However while the VMWare KB 2003582 states how to implement the preferHT setting it does not mention something Frank Denneman did say in his book: By disabling the Hot add CPU feature and by adding the preferHT set to True I increased performance quite a lot and I expected to see cores spread onto two physical sockets. According to Frank Denneman's book vSphere 6.5 Host Resources Deep Dive I aimed at keeping the VPD onto as little psockets as possible. ESXi 6.5 are HP DL560 with 4 sockets (22 cores each + HT) and 1.5 TB RAM. I have a VM with 64 vCPUs and 512GB RAM, it’s a massive db.
