BE6K supports redundancy over LAN and WAN. If you need full redundancy you can install another physical server hosting redundant VMs in a different data center (or a different location) depending on your needs.
Well, if you want hardware redundancy you can. I'd recommend building a subscriber for CUCM within the existing Be6K, and then if you want a second UCS c220, build a subscriber for CUCM and one for CUC in the second one..
So, it would look like this:
UCS 220 1, VMs:
