We are a small shop looking to migrate from a single LPAR 2066-001 to a z9. On a normal day we hit 100% CPU utilization for several hours during Prime Shift (8AM-4PM). The Prime shift workload consists of production online work (CICS, IMS and DB2) from our business community, development work (TSO, batch and online) from our programming and QA groups and a small amount of production batch.
Our batch window is about 10 hours. We run at 100% utilization during the first 8 hours, then drop to 50% for about 1 hour and 20% during the last hour. Our IBM reseller is suggesting we purchase/lease(36 mon) a 2096-Q02 and run it as a downgraded N02 for approx 6 -12 months (or as long as we can) and gradually add capacity as we grow. This is to save on our IBM and ISV software costs. Part of the cost justification for the purchase assumes 6-12 months running as a N02. We are concerned about online response times and our batch window after the upgrade/downgrade. Are there low cost/no cost tools that can model the work on the new machine? Should our reseller be able to do this for us? The CP3000 info they have shared does not give a warm fuzzy. They are also suggesting a zIIP. About 10-15% of the Prime Shift utilization is DB2 DDF work. Any additional tools to model the zIIP effect on the GP utilization? Any info or guidance would be appreciated.
