I'm sorry, but I have not had similar experience. Most SAN installs that I've worked on have mirrored disk, dual or better interface cards as well as cabling so that there isn't just one path to the drives. I have tried NAS setups that have failed badly, but thankfully those were in a testing mode. Never trust a sales droid, always push the "press-to-test" button.
The SAN's I have experience with have all that - dual HBA's, multipath,. etc.
They are still subject to failure and human error.
As usual, human error is the biggie.
