[cisco-voip] C200 co-residency

[Paul]

Hmmm....so one of those vCPUs must be allocated to the hypervisor. I did a double take when you mentioned that bit about the requirement of having one vCPU free for connection. So it appears in *that* case we would unable to do a WAN-split cluster with CUCM, CCX, CUPS, CUC, CUEAC on one C200 box, and the same configuration on the other box without EAC *despite* the fact that PDI Helpdesk stating that it *would* be kosher.

Now I -really- want an answer from one of the Cisco folks to be clear once and for all.

This is for UCS-C200M2-VCD2 x 2...which I guess doesn't matter since I just want the answer about shoving five applications onto one C200M2 box.

1. is it okay to mix and match the OVAs on a C200M2 or is it *only* supported in those listed configurations?
2. is it okay to put CUCM, CCX, CUPS, CUC, and CUEAC all on the same C200M2 or am I not? This is for 250 phones so all the smallest OVAs.

I would say as long as nothing is oversubscribed you should be fine.
In your example if the CUCM 1k is 2 vCPUs and the Ucxn is 4 vCPUs you
would be fine.  But if you tried adding another CUCM 1k that would put
you at 8 and Ucxn is only supported when there's a free vCPU.  This is
just for an example, I think the 1k CUCM's might be 1 vCPU.

I believe the reason we can get 4 on there today is because one of
those templates only really needs 1 vCPU.
