Interesting you should mention those technologies, as they both originated from Sun and have been ported elsewhere. While FreeBSD's ZFS is a solid port and probably the best non-Sun implementation, it's actually a few versions behind. It might be worth checking out OpenSolaris, despite its future seeming to be up in the air, with Oracle's acquisition of Sun.
