I am looking into a completely new Exchange 2007 SP1 deployment and my only concern at the moment is what kind of replication to use.
The initial architecture will consist of 2 Edge, 2 Hub, 2 Cas and 2 Mailbox servers. What is the recommended replication method to achieve high availability? There are currently two SANs in place and in a few months second one will be moved into another building.
Which is the way to go? CCR? SCR? Which can scale better (CCR allows only up to 2 node clusters?)? How about 10 active mailbox servers and 3 - 4 passive, is this kind of setup possible?
Thanks in advance!
