All I know is this:

After running ZFS for the Cyrus mailstores for a year now I'd never go back.
If someone told me here's a bunch of white-box PC hardware we want you to
run OS-Y and filesystem J I'd say find another boy to run it or double 
my paycheck.
For trustworthy mail-storage there isn't anything comparable and you 
know how
nervous people get about mail outages.  I haven't had to look at an fsck 
prompt
in over a year, and that is sufficient reason for me.  Being able to run 
a scrub while
the system is live after replacing a disk, with no impact, just to be 
sure it's clean
is way into bonus points.

But we already run both Solaris & Linux so it wasn't an "unknown" for us.

YMMV
