I'm looking at the database availability groups in regards to creating a constant replication of the mailbox database.
Here are three options I'm thinking of (and sorry if I'm wrong with my assumptions on this).
- Completely new server, doesn't need to be high-end. Normal server to only house the Mailbox server role of Exchange 2010 and create the constant replication.
- I have a secondary DC that does absolutely nothing but the tasks of the DC. Install the Exchange 2010 Mailbox role on that system and create the constant replication.
- Add another drive to the Exchange 2010 server, and add a Mailbox database to that drive and start the replication here.
What do you guys think the best method/practice for this would be?
I should note: my thought is just a new server for the replicated database. I don't really like the same server idea. possibly even have this server at a different location - remote store etc. to hold the replication. I'm not 100% sure how it works yet however.
