UC apps redundancy

[raid_t]

Hi there,

If there is a Pub and a Sub each on their dedicated server, I understand that this provides redundancy for CUCM, but does that mean that CUC is redundant as well? 

Thanks in advance!

If you're asking if you can create a CUC cluster, the answer is yes, but it's only a 2 server cluster, unlike CUCM which can go up to 8 running CUCM and 20 in total.

This sizing deployment states for up to 5k users or devices 5 nodes are required: 1 pub, 2 tftp and 2 subs.
What are some good combinations for having these nodes in 2 physical servers like 7k?

Thanks in adv.
