what you do not understand is that a proper SAN is NOT an complex setup, it is in many cases a simpler one because you have TWO controllers, disks with DUAL channel and a proper RAID level in ONE device
to built all this redundancy at your own is a much complexer software-setup and you can be pretty sure taht as long you are not dealing night and day with storage/Failover-setups the people designing a SAN have much more expierience what the are doing
Is not my experience with some pretty large ISP's, SAN might have its place for web, but not in any mail world I'm responsible for, stress testing has shown me no SAN speed difference of NAS for mail (yes this may differ is an office world, but not when dealing with the size of emails) and I sure as hell wont pay the extra gazillion these vendors want for the SAN gear.
