We've got an 11-way /tmp in house.  Gotta do *something* with those pesky
a partitions...

It helps to have multiple controllers (isn't that *always* true?), but in
reality, ConvexOS can stripe together (if you reeeeealy want to)
any assortment of partitions, as long as they're on the same *kind* of
controller -- typically the old xy451, newer iphase 4200, or our own IDC.
You're warned, however, if you specify two partitions on the same drive.
This must be an ooooold customer -- we haven't done Eagles in a good while,
and we sell very few of those crufty xy451's any more.

Personally, I've never really been convinced that striping is always a
performance win on a real-world machine with a large number (like 80) of
simultaneous users.  If you've got n MB/sec coming through your I/O system,
does it really matter how you slice it?




(I'm just a sysadm, not a salescreature, and I try very hard to not sound like
 the latter).
