BES upgrading and clustering
I'm considering upgrading my BES from 4.0 to 4.1.6 (most current?), which is running on Server 2K, but will be upgraded to Server 2K3. The question I have for you server folks out there is whether the most current software supports Server clustering? Since the BES is considered by my company as 'mission critical' I would like it to failover to a secondary server if/when the primary server should fail.
Logistically I figure I'd have to have the database in a location (SAN?) that both servers would reference.
I've never heard mention of BES with custering in a traditional sense, but RIM considers the BES to be mission critical as well and has a number of ways to make this work.

BES also supports SQL replication to another server, but only one way. (i.e. you can't, to my knowledge, point BES servers at each of the replication points, only one end. The other end is for backup only.)
If you really want to get crazy (or have performance issues) you can split many of the services from BES off onto other boxes. This helps your fault tolerance - if one box goes down you may not lose everything.
Even without additional licensing you could set up a second BES without starting the services. If the first BES fails you bring the second up and quickly reassign your users. Since both are pointing to the same DB server everthing should be fairly transparent to the users.
RIM has a doc on disaster recovery on the btsc, but I can never get direct links to there to work, so go search for "disaster recovery guide."
I also recommend taking the RIM classes on BES - I just took the Advanced Features of BES 416 class and there is a whole chapter on Business Continuity Management.
I think the best solution and for Domino the only solution is Neverfail. We currently have it running on our test server(s), soon to go into production.
VMWare, Hardware fault tolerance. I have it running on it and so do others on here. It is the best solution in my opinion. With the right setup you can have no failure.
This is the setup on our BES.
