I would stay away from the CMD product. It seems pretty nice, but we've been holding up a similar migration for a few months because CMD cannot help us figure out why the controller "disappears" for a few minutes now and again. We`re running 2.2x with CAM. The mylex is used in wcarchive, and I believe it may be the better candidate just because it's in active use and there are no "unsupported OS" issues. See related thread on freebsd-scsi... Look for "5440" and "spork".
