I am little puzzled about creating an Exchange 2010 DR environment in case if production site goes down.
Here is setup we have:
2 Active Directory sites in 2 states connected with 50MB pipe
All servers including Exchange is in SiteB
All users are in SiteA
We have 2 Exchange Server 2010 in a DAG, 1 CAS and 1 HUB. Users connect to CAS using server name and all is well so far.
Now management want to have a DR solution
I am thinking to have one Exchange server with Mailbox/CAS and HUB and part of the DAG in SIteA. in case if we need to fail over, how would i redirect users to new CAS? is this the best solution? Please let me know your opinion!
