I currently have a DAG setup with 2 vm's at our main office. I am now going to setup two remote sites with their new exchange 2010 servers but just want to make sure on what I need to do.
We are going with one large DAG, and I want two copies of the db at each remote site and one copy from each remote back at the main site, so basically Active/Passive
So do I need to setup 2 vm's(exch 2010) at each remote site or just one, and do I need the CAS and Mailbox server roles at each remote site and do I need the hub transport at each remote site?
Any help with this would be greatly appreciated.
