When looking at processors for servers to be used with ESX/ESXi, which features should be most important?
That is, from the wide range of CPUs available, what should best spent money for a customer?
Would it be the frequency of the cpu, or the amount of cores, the cache sizes, features like hardware virtualization support or any other things?
I am not looking for a specific CPU to buy at the moment, I am just interested in the topic and which considerations that could be made.
