I don't think anybody has mentioned the block level compression in ZFS
yet. With simple lzjb compression (zfs set compression=on foo), our
AFS home directories see ~1.75x compression. That's an extra 1-2TB of
disk that we don't need to store. Of course that makes balancing vice
partitions interesting when you can only see the compression ratio at
the filesystem level and not the volume level.
Checksums are nice too. There's no longer a question of whether your
storage hardware wrote what you wanted it to write. This can go a long
way to helping to predict failures if you run zpool scrub on a regular
basis (otherwise, zfs only detects checksum mismatches upon read,
scrub checks the whole pool).
So, just to add us to the list, we're either ext3 on linux for small
stuff (<10TB), and zfs on solaris for everything else. Will probably
consider XFS in the future, however.
Why not ZFS on Solaris x86 for "smaller stuff" as well?
