cucm cluster design guide

Hi all,

I have been given 2 ucs c220 use for cucm clustering on vmware esxi.

I have installed vmware esxi along with the cucm on the first server (publisher).

Do I need to install another cucm in the same server or in the second server for subscriber?

please guide me as this is my first experience on this.

many thanks

You can install as many CUCM subs as you wish (up to 8 call processing in a cluster, 20 total servers) as long as you have sufficient resources on your servers (CPU, RAM, Storage).  This comes does to your redundancy design, number of devices, etc. Have you reviewed the CUCM SRND?

Thanks Chris for the guide! I'll spend my time on CUCM SRND for better understanding on the design.

No problem, it all comes down to the size of your environment and redundancy requirements. 

HTH, please rate all useful posts!
