[cisco-voip] moving unified servers to DR site

[Jason Shearer]

Correct….I glossed over the IPCC requirement.  UCCX 8 will support geodiverse HA.

Cisco doesn't presently support CRS HA servers separated geographically.

UCM and Unity are both supported in HA configurations,  depending on minimum bandwidth guidelines and/or response times.

Regardless of what your consultants say, please bear in mind the Cisco recommendations are also guidelines for them to support you.  If you run into HA issues with unity or IPCC and you go to get TAC support, there's a good chance you're not going to get full support out of Cisco if the overall system design doesn't meet requirements.

We do it but have more than 10Mbs.  The most important thing here is latency and QoS.  Monitor the bandwidth between the servers and adjust service policies accordingly.

We are trying to move our secondary HA Cisco unified servers to the Sun Guard DR site.

We are going to install 2nd CUCM subscriber server at the DR site and move Secondary Unity and CRS server to the DR site.  Leave Primary Unity and CRS server at the Corporate Data Center.

Question is this: We are going to have ATT 10Mbps MPLS circuit to the Sun Guard.  Per Cisco document you at least have to have 100Mbps connection to the High Availability Servers but per our consultant people, 10Mbps is sufficient.  I think this design will work fine but want to hear second opinion.

Has anyone done this before… Do you see any issue with this design?

Thanks for your help.
