More/Slower vs. Fewer/Faster CPUs: Practical Considerations

Project and Program: MVS, MVS Performance

Tags: Proceedings, 2016, SHARE in San Antonio 2016

Mainframe customers have had a choice of processor speeds for years. This flexibility has been somewhat limited by the number of sub-capacity engines that can be configured. But now with the z13; up to 30 sub-capacity engines can be used in a single machine; which opens the consideration of sub-capacity engines to more sites. What are the advantages to using sub-capacity engines? Does your LPAR configuration matter? What metrics should be examined to determine if more/slower CPUs is a good fit for your workload? Is it possible that this choice might impact your software bill; either today or in the future?
Come to this session with Scott Chapman to learn why more/slower CPUs may be a better fit for many environments and how to determine what workloads might be at risk for moving to slower CPUs. Representative configurations will be examined and discussed.-Scott Chapman-Enterprise Performance Strategies Inc.
