I need to add a secondary Blackberry Enterprise Server to my Domino email infrastructure for redundancy.  What is involved as far as MX Records, DNS, RIM??

Here's my current setup.

Mail Server A (MX 10)
Mail Server B (MX 20) with Blackberry Enterprise Server 4.x in remote location.

Both servers are members of a Domino cluster.  I plan to add another Domino server with BES.  How does RIM know to contact the other BES server in the event one of them is down?  (..I maybe asking the wrong question and so please advise me if necessary)

Thank you!!  Experts on EE on great!

Are you looking for an active (hot) failover for BES? I don't think that was supported until version 5

as brwwiggins has mentioned, you need to be running BES 5.0. In which case the two BES use healthscores, written to the config database and maintained through the blackberry dispatcher service.

The smarts are in the application-layer, rather than network-layer failover.

Yes, I intended the additional BES to be a hot failover.  I see what you guys are saying now.

Is the Blackberry dispatcher service on the server or on the handheld or both?

dispatcher service runs on both servers, primary and standby. You don't need to worry about it as it's installed automatically on the BES (your current BES will also have the dispatcher service installed and running - it's responsible for many things, including encryption/decryption compression etc)

You will definitely need to upgrade to Ver 5.0 to do this properly.

I am in the middle of testing in my Lab.

I hope this helps !

one thing to add, I noticed you said your other BES server was in a remote location. For the failover to work the servers will have to share the same SQL database which means they will either have to be in same location or require SQL DB replication.

Something to consider in your design. There are a few documents on the RIM site talking about high availability for BES that are worth reading http://na.blackberry.com/eng/deliverables/7325/BES_high_availability_292701_11.jsp

brwwiggins,

Great information--thanks.  I did not know about the SQL setup.
