Many customers only replace their mainframe every 3-5 years, so properly planning for what machine to go to next is not something they have a lot of practice at. Many simply rely on their vendor to make a good suggestion. But the wise customer will consider multiple factors before making a final decision. In this session Scott Chapman will share the insight he has garnered from years of planning processor upgrades. He’ll talk about some of the high-level differences between the z17 and recent processor generations. He’ll explain why moving to slower CPs may benefit both performance and finances and how zPCR can be used to examine that scenario. Finally, some thoughts will be provided about understanding the performance changes after the upgrade.
Scott Chapman has over three decades of experience in the IBM mainframe environment. Much of this experience has focused on performance, from both the application and systems perspective.
