I am testing a Citrix Solution which has been successful but I now need to investigate the next stage.
The test scenario we currently have consists of the following:
2 Citrix server Farms
1 Web Interface (Although in the final solution we will use 2)
Advanced Access Control Server
The current testing scenario is that users will come into either the AAC and be forwarded to one of the farms based on an End Point Scan OR they will come in directly to the Web Interface or directly to an application.
For disaster recovery purposes, we are wanting to duplicate the above and have it in a different location. In the event of a failure, we would want to (as seamlessly as possible) move users to the other site. This can all be handled by Virtual IP’s so I was wondering what the best way to achieve this is?
My thought was that we could have 2 XML servers one on each site (with the single VIP address) and host records for each but I am not sure if just having this is sufficient. Therefore should the main site fail (which has the primary server farms), the XML server will automatically redirect all traffic to the DR server farms, without the user interaction – until the main site comes up. Now this scenario can be useful if a failure of the server farm or the failure or the XML server at the primary location.
Any advice would be much appreciated.
