Does anyone know if it's possible to control/manage/limit/(etc) the IO 
in terms other than bandwidth?

Just thinking that for hard drive technology, the # of IO's per second 
can be just as important as the overall bandwidth.

If it's not something that's controllable by anything we support though, 
then it probably doesn't matter. ;)
