John,

Have you looked at the spec for an i595?

http://www-03.ibm.com/systems/power/hardware/595/specs.html

This monster can have up to 4TB of RAM. 1700 jobs would be mincemeat for it, whatever they were doing.

Crispin.

Oh, the places you'll go!

On our model 550 at the current moment we're running about 1700 jobs
across 3 LPARs using a single processor. I know many others
here on the
list have much bigger and more complicated environments.

You're running 1,700 jobs concurrently? What are they doing? How "big"
is a model 550? We have a z9BC model V02 (2 processors) and month end
always pegs the CPU.


Once you get used to the i you'll wonder why you didn't do this years
ago. Many of the mainframe concepts you're used to will
transfer almost
directly, like the "hipersocket" concept.

Well, this was looked at in 2004. However, at that time (and that now
ex-) management really wanted an "Windows only" environment and only
thru in the iSeries in an attempt to look even handed. When we (Tech
Services) showed all the submerged ice burgs in that. And the fact that
the vendor hawking the Windows solution could not answer our questions,
that died. Of course, we (Tech Services) are still held in disrepute
because we were not "team players".


Regards,

Scott Ingvaldson
