In this course, you will be introduced to the methodology for analyzing performance of Symmetrix arrays. You will learn to analyze Symmetrix performance using ControlCenter Performance Manager and Symmetrix Performance Analyzer tools. Metrics that are relevant for analysis of each of the components in a Symmetrix array are presented. You will learn to identify bottlenecks for performance and provide recommendations to remedy the problem. Hands-on lab exercises using performance archives reinforce the concepts and methodology presented in the lecture.

Highlights

• Relate knowledge of the Symmetrix architecture and I/O handling processes to their performance benefits
• Performance impact different types of workloads have on Symmetrix architectural components
• Use key metrics to identify performance bottlenecks and component over utilization
• Make performance-oriented recommendations when allocating new storage or migrating applications
