Actually, the STORAGE number had a very well-defined meaning. It was just
useless for any form of performance management.
<tutorial type=brief>
The number represented the percentage of pagable storage occupied by the
pages of in-queue users. Since most users -- even active ones -- spend much
of their time not in-queue, it tended to under-report the amount of storage
used/needed (slightly or badly, depending on the workload). How many times
have we seen the question "My storage utilization is only nn%. Why is my
system paging?" on this list?
