Yes it does.

My only complaint about NetApp is the price of their stuff (i.e. NFS
License = $13000 per filer).    The 2 big advantages of NetApp is that
all of it's software is included within DataONTAP OS, which is based
on BSD, and is simply unlocked with a key the other is it's snapshots.
 Unlike other SAN manufactures that create delta files for snaps
NetApp uses block level locking and block pointing at the 4k level.
So no additional  files are created as a result and less space used.
Also there's less of an i/o hit when snaps are taken.  Very cool
stuff.

Yea...but that is all been dismissed.  I think it was more of a
personality conflict between NetApp's CEO and Sun's.  They had quite
the little blog war going on too.
