No, we don't have a SAN now. IBM is trying to sell us one. I am just looking into ways to incorporate it into our existing configuration before making a recommendation to my boss. Our Exchange database is about 40G. It is being backed up directly to tapes through the LAN to FC 3590E tape drives in a 3494 and runs for 2 hours.
