Ian, in regards to your question - our own concern is with ZFS in general.
Though we're happy with its performance in a Development environment, we're
leery of implementing it in production until we have it more widely deployed on
the more 'stressful' (i.e. everyone runs something all the time) test servers
and see what happens.
We also don't like the idea that a corruption of the 'master indexing file'
held on the boot disk will effectively wipe our entire configuration without
recovery (we use our adv_file disks as a sort of 'data warehouse' for certain
types of backup, so this is a showstopper).
Lastly, from our own testing here, RAID-5 on hardware is usually more efficient
on our SPARC servers than any software-based one (the sole exception,
paradoxically, being Veritas VxVM on a FC JBOD).
