BES will continue to function without SQL connectivity for a period of time.
How long depends on the size of your environment, and how "busy" it is.
You'll lose some statistics during the SQL outage, but mail will still flow.
According to RIM employees we've heard speak at WES, there have been instances where large environments have been without SQL connectivity for up to 6 hours.
Your milage may vary, but I think you'd probably be OK with a 30 minute outage.
When SQL comes back up, BES should just simply reconnect on its own and pick up where it left off. At most, you might just ant to restart the Blackberry services on the BES if anything quirky arises when SQL comes back.
