[cisco-voip] help explaining UC on UCS CPU requirements

[Lelio Fulgenzi]

I'm wondering if someone can help explain some of the UC on UCS CPU requirements that I'm seeing. I getting a little confused by some of the terminology and stuff in brackets. 

When I read the OVA requirements for a 7500 user node, it says 2 vCPU (with 3600MHz reservation) and physical load calibrated to E5540 2.53 GHz. 

If I want to install this OVA on a UCS C240 M3S (SFF) TRC#1 which has Dual E5-2680 (8-core, 2.7 GHz) do I do some sort of reservation of total CPU Hz available? Or is it simply a 1:1 core assigned, vCPU to pCPU? 

The total Hz available is 8x2.7G=21.6GHz which means I could install 21.6/3.6=6 of these OVAs? 

Or do you do CPU math, 8/2 = 4 OVAs allowed to be installed? 

The math and disk space calculations seem much easier.
