[cisco-voip] HA With UCCX

[Nick Matthews]

The interesting part is that when you start talking about booting ESXi
from SAN, you start running into ESXi restrictions and not Cisco
restrictions.  This is something VMware is still working on.  Note
this is different from ESX, but we went with ESXi because it's
VMware's future platform for roadmapping.
