Data Center Failover using DNS

[bravob]

Hi, at a very high level, we have 2 geographically separated sites, site A is the primary site with active servers to provide application access to the enterprise users, site B is the failover site, can I provide total and partial failover using Cisco CSM modules and/or DNS? This is for internal users, I already have GSS running for external access and Load balancing, I'm currently routing between the sites. Based on your experiences what do you thing is the best approach and is the CSM solution doable given the servers at each site are in different networks? thanks in advance.

we have two solutions in place for this.

F5 and Infoblox

The Infoblox we have set up in 2 clusters and they share their info accross the network. One place for updates and it replicates itself between clusters.

This allows us to use one block of IP's and not have secondary DNS entries for the same device. Our DNS is active no matter where the location and we back haul the traffic if needed.
