My main server at home uses RF. I don't know what your definition of
production is, but since I work at home having a stable box there is
pretty darn useful. I've used it on pmax, alpha and i386.

I haven't noticed any specific CPU usage, but I've been working on the
principle that a mirroring is worth whatever price you have to pay.
Also, with a raid mirror you can get benefits with reads since you can
come off two spindles.

I don't have any hot-swap carriers or anything fancy like that. I just
shut the box down when a disk fails.

I've used raid5 in a past life, and have been using raid1 at home for
around 3 years. I had some IBM 45G deathstar disks, and I've been
_very_ happy that I've had RF mirrors. At a guess I'd say it's saved me
about 8 or so times in the last three years.

Can't help there.
In summary, I doubt I'll ever use a production box again without some
form of RAID mirroring, and I've been really happy with RAIDframe in the
time that I've been using it.
