Due mainly to licensing rules imposed by Oracle and Microsoft, there is
an increasing demand for either locking VMs to specific hosts (like with
VM-host-affinity rules) or for decreasing the number of physical CPUs
or logical cores in the ESX hosts.
For HP hardware it is possible to order Blade servers with 2, 4, 6, or 8 cores - at least for BL460c Gen8. But in my company, we like to keep things as standard as possible, not having too many different hardware models.
As per Gen8, it is possible to disable a given number of cores in the BIOS. It has to be increased/decreased in pairs from 1 to 8. So as a minimum you can have 1 core enabled on each CPU. It is not possible to deactivate one of the physical CPUs.
