I don't know if this is as relevant anymore... On a terabyte system that
would mean having 200GB's of empty disk, at 80% utilization...

I think you need to understand what your disk IOP and disk arm utilization
is along with you disk usage growth history. If you have enough arms and
IOP's and the arm utilization is 5-8% then running in the 90% full range
should be acceptable. 

Another benifit would be not having to explain to a "bean counter" why the
iSeries won't run correctly unless it has 200GB of empty disk space!
