We have 1 Active Directory forest and domain. We have 1 exchange 2010 server (on windows server 2008 SP2) managing all the email (delivery, receipt, and mailbox store). We were planning to add another exchange 2010 server to this setup so that we can distribute the load of the mailboxes to the second server. To be precise, given say 10 mailboxes , we would like to store 5 on one server and 5 on the second newly added server. Would this setup require a DAG setup?
From what I inferred on the documentation of a DAG, a DAG is more of a fault-tolerance setup. It involves a complete replication of your mailbox store over all the 'nodes' in the DAG. And in the case one mailbox store fails or is temporarily unavailable, the second mailbox store gets used. This would mean, in my example, that both servers would have all 10 mailboxes. Is that correct?
My question is if we can just distribute the mailboxes 50/50 over the two servers, and have half the users connect to the second exchange box, however still be able to email everyone else in the organization. What kind of a setup would that be? Anyone have links to guides, walk-through etc?
