CUCM servers in different locations - possible?

[Mark Boiston]

Hello

This may be a simple question but I've been asked to investigate it.

We have a CUCM version 9.1.1.10000-11 set up comprising :-

1 x Publisher

2 x Subscribers

1 x TFTP server

2 x Unity servers

2 x Presence servers

They are all currently located in two racks in a comms room in our Frankfurt office.

Is it possible to move half of them to another location to give us a redundancy scenario? Or do they need to be in the same place for some reason?

If they can be moved is it just a case of making sure the IP addresses are valid in each location or that the config is re-done to reflect the new IP addresses of the moved servers?

Thanks

Yes, review the guidelines for CoW in the SRND for the CUCM server and the CUC HA design guide to consider the BW and RTT between sites that is required to split them over a WAN.

That looks like what I need
