We are implementing BES 5.0 on Exchange with HA on BES servers and some sort of HA (hardware or SQL) on the DB side. The question is...what do we lose if the SQL database goes down? We know we will lose the ability to administer, but will we lose any services (IM, email, etc)?

Thanks,
zb

im sure others will chime in with a more detailed answer, but blackberyr will continue to deliver mail and such for something like 4 hours without a connection to sql.

But ultimately, you lose the encryption keys, configuration data, etc. In BES 3.x, when all of this information was stored in the mailboxes, the database was not really that much of a concern. Lose your database in 4.x, and you have a TON of work ahead of you. In other words, I would place a LOT of importance around the availability of your database, whether it be from a frequent backup or from synchronization through mirroring. Yes, messages will continue to deliver for 'up to' 4 hours (often it's around half that, at best), but you may as well start from scratch after that. Device wipes, reactivations, reconfigurations, etc.
