Hello Experts,
We have 2 date centers (DC) which are being used as the primary (DC1) and secondary (DC2) for all our Unified Communication servers. We are moving from ISDN PRI to SIP Trunking and considering to install the HA CUBE in the DC2 but all primary UC servers are in DC1. We have:
One CUCM Mega cluster version 10.5
Three Unity Connection Clusters version 10.5
Four UCCX Clusters version 11.6
Do you guys see any issues seperating the HA CUBEs from UC servers. Is there any recommandations that we need to take in consideration?
Thanks,
Mk

Absolutely fine, as long as the latency is within reason (under 300 ms), preferably under 150 ms, you did not state if your UC apps are already split between the data centers, but if so you are then already under the latency as UC apps have struck guidance i.e. 80 ms. Splitting the environment between 2 data centers is always a good idea.

Hi,
As @Chris Deren mentioned, there is no issue if you deploy HA CUBE's at DC2 as long as the round trip delay is less than 150 msec. But there are other recommendations/best practices which you need to take into consideration. Such as:
1. Single Point of Failure
2. Geographic Redundancy
3. Codec Consideration
4. Network bandwidth for all PSTN calls
Please refer to below document which provides best practices for deployment of Cisco CUBE.

Thanks Chris & Vaijanath,
Yes, all of our primary servers are in DC1 and secondaries in DC2 but the HA CUBE is going to be installed in DC2. All the recommandations mentionned by Vaijanath have been taken in consideration. We will have a singl CUBE inatalled in DC1 with a dedicated SIP line for redundancy perposes.
.
I guess all we need to do is to creat a Device Pool which has the secondary CUCM server located in DC2 at the top of the Cisco Unified CM Groups list which will allow the CUBE to point to the local CUCM.
Thanks again,
MK
