We currently are running Exchange 2010 that runs off SAN storage. Our primary configuration is in our main location that has 1 x CAS server, and 2 x DAG servers.
We are hosting Exchange for all our 2 offices abroad as well, meaning the users have to VPN here and open up Outlook or OWA from our main Exchange servers.
Might be looking to deploy individual Exchange servers for just those remote offices (they are currently in their own SGs) locally at their site however, would like to know how to best design this so that it is fast enough at their local site, but also can be backed up and accounted for from our main site.
Guess just throwing another CAS and DAG server at the remote site won't work unless it can specify which SGs/users?
