I ran DEC Alpha servers at the same time, and Tru64 (aka OSF/1 aka DEC UNIX) shipped with AdvFS. It has a lot of the same features as ZFS (volume management combined with the FS, so you could add/remove drives, and grow/shrink capacity w/o downtime). I remember my Sun admin friends being incredulous as I shuffled disk space on a live server. It is kind of a shame HP killed it.
