Simon, OpenSolaris does have it (block level dedup) since about one year but it is too recent an addition to the commercial Solaris 10 to start using it (IMO). Apparently (Wikipedia) it is ZFS pool feature 21 listed as 'Reserved' by 'zpool upgrade -v' (hmmmm... both 'zfs get all ...' and 'zpool get all ...' do not yield a parameter sounding as 'deduplication' ; it may very well not be there yet) Furthermore, I'd like to repeat what has been written earlier in this thread : a message header that is different in size by even one byte will cause block boundaries to shift and, I suspect, block level dedup to fail.
