Server Consolidation Using Performance Modeling

To fully realize consolidation benefits, businesses must focus on the performance and service levels provided to users in addition to reducing unused capacity. Performance modeling has improved the understanding of the performance of today’s multitier applications.Although traditional analytic and statistical techniques are useful for gaining insight into the performance of individual components, performance modeling lets the analyst further understand the dynamics,dependencies,and interaction among system components and how they contribute to the user’s experience. Here, we present a new way to analyze consolidation alternatives using performance modeling and stepwise refinement, a methodology for efficient and effective modeling. CONSOLIDATION OPPORTUNITIES First, consolidation opportunities can be defined in terms of three primary categories.
