Correct I do not have WAS, DB2, or Domino. My point exactly. What kind of users you have makes all
the difference in overcommit ratio. If I added 4 WAS machines I would need a lot more storage than 4
more MYSQL or Oracle machines.

Stephen, you are doing great. Your workload must be Oracle, and not WAS,
DB2 or Domino. If it is WAS, it must be old prior to "performance
enhancements". so don't upgrade it.
And the metric IS useful, you know if you add 4 more servers how much
more mainframe storage you need. And your number gives a reference point
to others to show what they could be doing if everything worked correctly.

My overcommit ratio is about 5:1 not counting CMS users. If you count
them it is more like 15:1. It seems to work fine. I don't think
overcommit ratio is very useful for anything. It is two dependent on
the kind of users you have to be meaningful.

I keep hearing things like shouldn't be overcommitted in prod more than
2:1 or 3 or 4:1 in test.
How is that calculated?
Can I just take the (Pageable storage number + Pages on DASD ) /
pageable storage number?
