For me, the really valuable pieces of ASM are the ability to add and remove
devices without taking downtimes and without having to worry about moving
files around.  If you have a high quality storage system that does that all
behind the scenes already, I can see where it might not be an advantage.
Most places I work with dont have that ability.
