This wil more than likely be handled by the SAN. Are there some benchmarks demonstrating significant performance gains over Veritas Storage Foundation?

Agreed. But I don't see the point of ASM. Veritas is very mature in this area. Most of Oracle's solutions are all volumes, not filesystems & most sysadmins cringe at the idea of raw volumes.

Is ASM still raw volumes? Isn't this why RMAN is the only option? Or can I actually run:

        mkfs -o largefiles -F ASM /dev/vx/rdsk/oradg/somevol

Oracle may as well OEM a copy of Storage Foundation and encourage development on Linux from Veritas since Linux seems to be big in their future.

The idea of DBA's doing OS related work (shrinking/expanding volumes etc..) is about as scary as sysadmins doing database architecture.
