CUCM - UCS Design doubt

[Jean Lofrano]

Hi Team,

I have 2 C220M3 UCS servers, and I want to creat a environment with 4 CUCM´s.

I´ve been thinking about: First server = (pub+Sub) + Second server (Sub+Sub).

What doy think about this? Is it the best solution?

thanks.

How many total CUCM are you planning on deploying? Are you putting them all on one physical server? That is not a good design.  Are you putting any other UC apps on this or other server?

Hi Chris,

How many total CUCM are you planning on deploying?

Answer: 4.

Are you putting them all on one physical server?

Answer: No. I want to put 2 CUCM in each server.

Are you putting any other UC apps on this or other server?

Answer: No, just CUCM.

Then you are perfectly fine. 

How many phones/users/locations are you planning on having here, do you need all 4 servers? Typically with C200/C220s the environments are small and do not warrant 4 servers, I understand that you have the resources, but think about future upgrades, support, etc

You can use this tool to see how many servers you might need:
