Given that I've heard it rumored that there will be some level of DR/failover capability in BES 5.x, I'm holding off on looking into 3rd party solutions and taking the traditional route. I'm doubling our hardware footprint and installing a BES instance on each "standby" server that's identical to one of the "active" instances and just disabling services. Then, if/when an active BES server fails, I just vpn in, enable services on the appropriate standby server and start 'er up. Less than 1 hour recoverability...perhaps even less than 10 minutes once my monitoring is properly tweaked.
I know that this is the most common method of DR planning for BES and for good reason...it works and doesn't take long at all to fail over, even manually. Next choice will be whether or not to spend money to automate that failover process (either homegrown or purchased from the likes of a Neverfail) or wait for RIM to add it to BES down the road in 5.0 or 6.0. For now, my recoverability requirements are less than 1 hour in a site-level disaster and I can do that without a 3rd party.
