[cisco-voip] HA With UCCX

Tue Jun 29 18:08:40 EDT 2010

Not sure about UCCX but CallManager is only FiberChannel no iSCSI for storage, CPU affinity requirements, the design guides go thru specific details and what's supported for virtualization.  I think their first stab isn't exactly what we had in mind when we asked for VMWare <girn>

Having just sat thru a 2 day UCS training session, I'm shocked by the following requirement:
-ESXi must boot from local disk (on B series)

Because it defeats one of the primary selling points of UCS.

With boot from SAN, you can re-provision a server in less than 1 or 2 minutes, from across the network.
