[cisco-voip] can ESXi run on UCS B200 when all vCPUs are reserved?

[Chase Voisin]

You can run at a max, 4 UC apps per blade but in your case you cannot.
 The Unity connection app alone will take 5 vCPUs.

Presence and Unity Connection both exceed the normal 2 vCPU per app
rule.  Unity Connection requires 4 allocated and evidently one
"inactive".  Presence requires 4.  When we get to CCM 9, things will
be different since presence is going away and getting thrown into CCM.
