Best Practices for Mainframe I/O SLA and Efficiency Optimization Features for the z/OS storage infrastructure such as FICON, Multiple Allegiance, and Dynamic PAV have all shifted the I/O queuing bottlenecks from the host to components inside the storage systems. Consequently, these bottlenecks have created a visibility gap into this mission-critical part of the IT infrastructure. The ramifications of this visibility gap are felt both in the efficiency of the infrastructure and in SLA levels. Performance problems associated with storage for example, are typically not realized until after they already have affected production workloads. In some cases, poorly performing storage hardware is replaced prematurely. When performance wins are needed in batch or online jobs, the impact of faster I/O (vs. CPU) is important to consider. This presentation describes the architectural changes and which metrics and methodologies are necessary to reduce SLA risks and improve efficiency. Download the hand-outs of this presentation

Getting the best performance out of your SVC V7000 DS5000 and DS8000 Storage Performance Management helps storage departments save money by keeping storage systems longer and get better performance at the same time. This session shows how you can achieve better performance from your existing disk storage systems while at the same time spending less time and effort on managing performance. It gives an overview of key performance metrics and configuration data, including monitoring storage performance with SMI-S. Key performance metrics are illustrated by reporting examples from IntelliMagic Vision. IntelliMagic Vision automatically identifies I/O issues in the making by using built-in intelligence about the performance capabilities of storage systems. So it is important to set your objectives before investing in storage that is more than ten times as expensive. These objectives should be set in terms of application performance, such that you know that the investment will matter to your important workloads. Download the hand-outs of this presentation
