We have customers running UniData on a SAN and very pleased with the results. The snapshotting really isn't as practical as they'd have you believe was probably the biggest negative surprise - their users were unwilling to deal with a 15-30 second 'DBPAUSE' more than once or twice a day, so the idea of doing a 'snapshot an hour' went out the window in the first week. Otherwise, the users don't notice the difference on the LeftHand SANs using gigabit ethernet we've seen out there. Just make sure you have the ability to prioritize and localize to 'hide' us from the constant Exchange disk assault -- but most anything will do that now in SAN-Land. Additionally, we have one client totally virtual -- Vmware Infrastructure and a SAN -- most of their end users are hard pressed to tell the difference.
YMMV ... But if it's rationally assembled, and ultimately 'looks' like a "Local" "D" drive to the UniData/UniVerse system - it can have good results and allow you to 'hardware mirror' outside your four walls. But shop carefully -- you'll want to go spindle happy. More is frequently better in these setups as it allows 1+0 mirroring in the SAN as well.
