[cisco-voip] UCS Sizing woes

[Justin Steinberg]

there are plenty of OVA templates you can deploy where the virtual machine
only needs 1 vCPU.  Also, if you go specs based, there are CPUs that go up
to 8 cores that you can put in a C220.  Two of those CPUs and you have 16
cores for your VMs.  At that point you are probably going to be concerned
about your disk IO if you have DAS
