If I remember correctly the post you are referring to was by Chris
Craddock, and he usually knows what he is talking about. I think Steve
may have placed Chris's post somewhat out of context, and it may be
worth re-reading something like that before either of you start tilting
at windmills. I have not re-read it, but my recollection seems different
to yours.
I'm wondering how many there are in our community that are still holding
off consolidating their 3380 Ds to Es, keep their LPAR to CP ratio less
than 2:1, will never use RAID-5, refuse to put more than 90GB behind a
DASD controller, and run channels at less than 30% busy. Once upon a
time these were things that were supposed to make MVS shrivel up and die.
A 32x80 Sysplex in the near future does not seem so farfetched when I
was working on an asymmetric 16 way Sysplex in 2004. All dedicated CEC
with up to 10xCP each as I recall and it ran just peachy. IMHO I think
it's quite neat how MVS can be made to adapt to what users want to do
with it.

Ron, you make good points, but senior management typically looks through
blinders. Things like lock management and I/O patterns can often have
far more effect, either good or bad, than limited CPU capabilities.
Serious overall analysis is necessary when considering any kind of
upgrade, so each shop can get the best "bang for its buck", but senior
managers all too often won't spend the time. They get all starry-eyed
when the salesman offers a particular upgrade at a "favorable" price,
then complain when the results are not up to expectations I believe that
this is call a "Aw, S***" moment, when the money's gone but the results
are lacking.
