[cisco-voip] CallManager 4.2 upgrade to 8.x on UCS

[Rhodes, Geoff]

We are about to upgrade our existing CallManager 4.2 system to 8.x, probably on our new Cisco UCS platform.  We have been told by our reseller that Cisco requires that the Publisher and Subscriber run on separate blades, and that NO OTHER APPS are allowed to run on those blades.  I am totally blown away by this.  Our phone system is relatively small (~ 400 phones), and I just cringe when I think that I will be using an entire blade to run a single server.  We were told they have to be running under VSphere 4 (ESXi), which is what we are running on all the other blades for our servers.  I mean these UCS blades are SO beefy, we are easily running multiple Exchange and SQL servers on one blade.

I simply cannot understand why it's required to have its own blade, especially when it running under VMWare.  As long as performance doesn't suffer, why would it even care?  I was told that we could run Unity and Presence servers on the same blade our Pub or Sub, but no other "non-Cisco" apps are allowed.

Grrrr.

Has anyone run 8.x on UCS?

Many thanks in advance for any help here...
