[cisco-voip] Cisco MCS vs UCS Servers

You can throw this at the TAC engineer if needed:

"You can also run a mix of virtual and nonvirtual machines, including the
servers in a backup or failover pair. Also note that to virtualize Cisco
Unified Communications applications, there is an additional support burden.
Customers provide the hardware, VMware ESXi software, and are responsible
for coordinating support for these components, including provisioning and
performance troubleshooting. Customers who are unwilling to take on such
support may be better candidates for deploying Cisco Unified Communication
applications on physical servers. "

I know the PM for this has specifically stated this multiple times.  If your
publisher in the lab was not on UCS then the engineer was correct that it's
not supported.
