Customer is having CUCM 5.1 7915I2, now he need redundant server for the above, can I suggest MCS 7916H4 for the above case.

Since one serve is 7915 and another one is 7916 there may be any problem in redundancy please light me, with different server model redundancy is possible ?

Hi Bala,

Servers within a Cluster do not need to match. So you can use a mix of 7855,7816 models within the same Cluster.

General Clustering Guidelines

The following guidelines apply to all Unified CM clusters:

--------------------------------------------------------------------------------

Note A cluster may contain a mix of server platforms, but all servers in the cluster must run the same Unified CM software release.

Hope this helps!
