Stream: Capacity & Performance
Time: 10:00 - 10:45
If you can't measure it, you can't improve it. IBM Z is arguably the most instrumented platform on the planet. z16 and z17 introduced RMF metrics that enable powerful storytelling. Learn how to get real value from them. Topics covered include LPAR home addresses, DPU I/O, AIU, and power consumption. Join Martin and John as they add their trademark colour to an otherwise academic subject.

With 35 years of mainframe experience (about 45 of computers), Martin is widely known within the industry, having presented at many conferences and having authored a number of IBM Red Books on performance and other matters. He continues to develop System Analysis tools he uses every day in some of the most difficult Performance and related mainframe situations IBM customers encounter: He has a very wide range of experience of what enterprises do with their System z mainframes. Getting "low down and dirty" with instrumentation gives him a rare insight into what the data can do: He leads others - customers, IBMers, business partners, and other vendors - in getting the value out of this instrumentation. With that experience base he drives conversations with developers about enhancing instrumentation, as well as their products in general. But it's not all about the mainframe: He has a wide range of other technological interests. For example, he knows a lot about programming and how the web is constructed. A while back he started the Mainframe, Performance, Topics Podcast series with Marna Walle. Since 2020 Martin has been busy open sourcing a lot of tools he's written, some directly related to Mainframe Performance, others in the "authoring tools" category.
John Baker, Principal Consultant at IBM, has been working with mainframes for over 30 years, both as a customer and consultant. His primary focus has been on system and application performance. As a customer, John designed, implemented and maintained many critical projects such as WLM Goal Mode, GDPS/Data Mirroring, and merging datacenters. As a consultant, John has assisted many of the world's largest datacenters with their z/OS performance challenges. John is a frequent and much appreciated speaker at industry events like SHARE, CMG, GSE and IBM conferences. He has served on the Board of Directors of the Computer Measurement Group (CMG) and currently volunteers with the MVS Performance Project (MVSP) at SHARE. In his spare time, John enjoys pool, motorcycles, his dog, old port and a spirited political debate. He lives with his family near Toronto, Canada.
