Unity Connection 8.6 - HA

StefanDietrich · ‎09-23-2013

I have a customer with Unity Connection 8.6 running on a 7825I5 Publisher. Now he wants to set up HA with a UCS-C220 as Unity Connection Subscriber. Are there any concerns about this installation or isn't it a problem to run one MCS (Publisher) and one UCS-C220(subscriber) server in a Unity Connection HA cluster?

No there is no problem, but you should use an ova file that matches the 7825 specs. Is there no option to put both servers on the UCS?

Hi Stefan,

This is a supported config

For a cluster with one physical server and one virtual machine:

–The specifications for the physical server and the virtual machine should match as closely as possible for available hard-disk space/vDisk space and for RAM/vRAM.

–When the hard disks in the physical server and the virtual hard disks in the virtual machine are not the same size, the smaller disks determine the amount of disk space available for voice messages.

–When the number of users supported for the physical server and the virtual machine do not match, only the smaller number of users is supported for the cluster.

–With Platform Overlay 1 servers, you must add 2 GB of RAM to the physical server so the amount of RAM in the physical server matches the 6 GB of vRAM configured for Unity Connection on the virtual machine.

Note In case of performing any troubleshooting steps, the Cisco support personnel may request for the additional RAM as required.
