We have deployed an IMAP server running on Cyrus on FreeBSD 6.2, with a 500GB UFS2 partition mirrored with geom_mirror and geom_gate across a dedicated 1gbps link. It has proven to be very stable and reliable after appropriate tweaking. The uptime of the mirror is usually 1-3 months, sometimes it seems to break randomly, possibly because our timeout is too low. In any case, it doesn't take too long to rebuild at about 60mb/s. (I recently tested the same solution with FreeBSD-7 and found it now goes at a full 100mb/s.)
