Beginning with z13 processors and continuing with z14s, customer experiences have confirmed that delivered capacity is more dependent than ever before on effective utilization of processor cache. This session covers how to interpret the SMF 113 metrics to optimize your environment and reduce CPU consumption and MLC software expense, and reflects findings from analyzing detailed processor cache data from 50 sites.
Details on z14 cache design changes will be presented and assessed using metrics from a z14 migration case study.
Insights into the potential impact of various tuning actions will be brought to life with data from numerous real-life case studies. This session builds upon a related user experience presentation that was selected for the 2016 “SHARE Best Session” award and 2017 “CMG Best Paper Award,” but has been significantly expanded with knowledge and experiences gained from reviewing data from dozens of sites.
Processor Topology – A Picture Says 1024 Words
We all know that our z/OS LPARs rely on processors to execute the code to run our business. We also need to plan on having sufficient resources available for our workload when we design our LPARs.
Conserving MSUs – Déjà vu All Over Again
In the past, you probably only focused on MSU usage during your peak 4HRA. Now, thanks to IBM's Enterprise Consumption, paying more attention to MSUs at non-peak times literally “pays” in terms of saving real money.
