For a variety of reason our exchange server goes down regularly and that's just the nature of our environment.  I would like to have a backup exchange server for when the first one goes down.  Is that exchange clustering?

I would certainly steer you away from clustering. Operating a cluster requires specific administration skills and different ones from running a standalone Exchange server.

If you are having server problems I would suggest you fixed them rather than adding another level of complexity to the environment.

One thing that might help you is one of the 3rd party solutions; Double Take, Neverfail and WANSync from XOsoft. They do not require the same skills as clustering and are easier to manage.

I would still suggest you made every effort to take away the problem from the current Exchange server.

I appreciate your comments, however their is nothing wrong with the exchange server.  It's just part of the environment that we have here that it needs to go down on a regular basis, don't really want to get into the details.

We use doubletake here and it would do the the job.  However, my question still remains unanswered.  Would cluster allow one exchange server to go down and e-mail to stay up and available?

Well then, yes, operating a cluster on shared storage would allow you to have one node take over the work when you needed to take down the active node for whatever reason you have.

Be aware though that you will need new hardware and shared storage and you cannot simply add another server next to your current one and convert the current standalone box to be a cluster node.
