Against UFS, of course [1] :-) Their hype is "our journal is faster than
UFS", which is probably true. They have extent-based allocation,
which is good for their greatest hype - performance with databases
(see all the marketing shredder-food about [Cached] QuickIO).
They have hot resizing, which fast as hell (again, compared to UFS),
they have snapshots, which are cool. And don't forget the GFS capability,
which I am yet to see in action. [2]

So in Solaris world, for large filesystems, Veritas is the winner. I am
really looking forward to seeing how will they do in the OpenSource

[1] Actually they benchmark Oracle on raw devices vs. Cached QuickIO, too.
[2] Even tough the options are expensive, in my experience all of them
work perfectly.

Kind regards,
