I don't really know about ZFS, on AIX JFS was found unsuitable for anything to
do with TSM, now we have JFS2, which is so much better that you barely notice
the difference between files on JFS2 or RAW volumes. I'd imagine that on
Solaris, the evolution on filesystems kept up and that ZFS will do very well. I
see no reason not to use ZFS for DISK type volumes. Your box has plenty of disk
to share the load....
