Same here. We use an EMC san and don't do anything specific to Unidata. It is just more disk with extra benefits such as load balanced multi-paths to the SAN with failover (twin fibre cards in the server), SAN based snapshotting. If you can afford the hardware and licencing you can do SAN to SAN mirroring etc. The disks are just available as any other disks to the O/S and it just goes. I would be interested in reading the white-paper but given the layers in place (SAN LUNs, the fibre multi-pathing, linux LVM etc.) and the wide variety of SANs, this could be tricky to write at any level other than the most general terms (e.g., give U2 its own spindles on the SAN, turn on read caching etc.). Add to the mix that many SANs host storage for multiple apps and you may not have the ability to tune the SAN to UD only, you would just need to rely on the SAN doing its job, which in our case, it does pretty well.
