Hi,
ESXi 5.x supports 64 vcpus , would like to know how vcpus are calculated .i have a intel server 2 processor - 8 core so my total core is 16 but . how 64 vcpuS would be calcuated in this server .
how no of processors ,processor per core and vcpus are calculated ..
Regards,
Ram
Hope this KB explains you question VMware KB: Setting the number of cores per CPU in a virtual machine
Thanks
>>> ... how 64 vcpuS would be calcuated in this server
You cannot configure more vCPUs than the available logical CPUs on the host.
In your case with a host with 2 CPUs and 8 cores each, you'd end up with 16 logical CPUs (or 32 if HyperThreading is available), so the maximum vCPUs you can assign to a single VM would be 16 (or 32).

Hi,
Our cpu having HT Technology so 2*8*2 = ideally 32 Vcpus can be generated in each EXSi Server .is it correct .

That is correct the maximum number of vCPUs you would be able to have in a VM is 32 since the maximum number of Logical CPUs you have is 32 - how ever I would not recomend that because the ESXi host will needs cycles to run and this could cause contention for CPU cycles -
Hi,
I would suggest you to go through below blog, which will help you setting vCPU as per need to avoid CPU over provisioning.
vCpu vs PCPU
Thanks
