John--What you are talking about is great, if you are for-profit company (or an extremely large non-profit like yours) with far greater resources at your disposal than many companies have. You have almost 3 times the servers in your one lab than I do on our entire network. I have a 5 TB NAS, but only one. The least expensive SAN solution that would have met our needs was triple the cost, so our databases run locally, which works out fine. Server and SAN replication is a wonderful thing and I wish I could do that, but comes at a cost that is astronomical compared to RAID. Tom reminds me of the yacht club president sniffing over port and brie about the terrible conditions that he is forced to endure on the water with all the riff-raff commercial fishing boats about. Why can't they be more like him? ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
