CUCM 9.1 - UCS platform C220 M3 chassis - Max number of devices

[Dominic Ellis]

Hi,

We've got a UCS platform C220 M3 chassis with 1 pub and 2 subscribers running.

Can someone advise of the maximum devices we can host on the 2 subscribers before

we need to add a further subscriber?

If you can point me to any docs that'd be really helpful.

Thanks

Dom

That depends solely on the OVA you deployed when building the servers

Whether you need another SUB, or not, you should be able to tell by the number of phones, your redundancy requirements, and your growth. If you're not familiar with this, I strongly suggest you engage a Cisco partner so they can review your deployment.
