[cisco-voip] Adding a Sub server in the existing CUCM 8.5 Cluster

[GR]

Thanks Abdul. The cluster is made up of UCS C210. But I want to add new server with a capacity for maximum of 200 users. Which Specific UCS model would fit in? Which model is basic? I guess do I buy the server with resources run two VMs at the most. 

Or would it be cost effective to use MCS in this case (which I want to avoid)?

Can anyone guide on the server size and which server would be most cost effective? Also if someone can guide on the VMware licenses?

Thanks

> While Cisco recommends using the same server model for all servers in a cluster, mixing server models within a cluster is supported provided that all of the individual hardware versions are supported and that all servers are running the same version of Unified CM. However, differences in capacity between various server models within a cluster must be considered because the overall cluster capacity might ultimately be dictated by the capacity of the smallest server within the cluster. Mixing servers from different vendors within a cluster is also supported and does not have any adverse capacity implications, provided that all servers in the cluster are the same model type
