There has been debate in out office over this for a while
It seems impossible to get a simple answer here - these are my hosts and I want to get the max power out of them
Do I go to 64 cpu at 2 x 32 or 1 x 64
I actually Probably only need 32 max as the load on the VM will take too much form the host but just for hear say - whats the best for fine tuning.
Dell Poweredge R640
Physical Sockets = 2
Logical Processors = 64
I assume that's 2 x 32 cores
I think the correlation of cores to VCPU - is the discussion here
So as long as I don't go more than 32 that directly maps to logical to numa - but what's best here -
32 Vcpu - cores per socket 1
16 Vcpu - cores per socket 2
2 VCpu - cores per socket 16
