We are looking to implement a DR\Failover plan for our Exchange CAS servers. We are having a tough time leveraging a solution for having the DR CAS server take over in the event of a failure.
Our current setup is as follows:
(Above servers are in a CAS array named PROD-CAS00 which is a VIP being load balanced by a KEMP NLB)
(The above DB servers and the DR-DB01 server are in a 3-node DAG group)
Our DR setup is as follows:
The idea is that if the Prod CAS servers as well as the KEMP NLB goes offline in production, mail flow in production will be redirected to the DR CAS server. Ideally we would like to keep the Outlook clients connected to exchange via the DR-CAS01 server.
Any direction\suggestions would be appreciated.
