How much zIIP workload do you have? You could go to a "smaller" machine if you have quite a bit of zIIP workload.
We went from a z14-706 to a z15-608 both having 4 zIIP's. We have a significant amount of Db2 DDF work. So going from "fewer faster" to "more slower" GCP's and having faster zIIP's our CPU utilization, both GCP and zIIP went down. DDF work that was running on GCP's because we did not have enough zIIP could no go to zIIP's thus reducing work on GCP's. Since the zIIP's were faster, that work was completing in less time. Using zPCR is the way to go as that should help identify what will work for you and your workload. -- ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
