Course Overview

Duration: 4 Days

This course introduces participants to the methodology for analyzing the performance of Symmetrix VMAX 1/2 arrays. Participants will learn to analyze Symmetrix VMAX performance using ControlCenter Performance Manager and Symmetrix Performance Analyzer tools. Metrics that are relevant for analysis of each of the components in a Symmetrix VMAX 1/2 array are presented. Participants will learn to identify bottlenecks for performance and provide recommendations to remedy the problem. Hands-on labs exercise using performance archives reinforce the concepts and methodology presented in the lecture.   Who Should Attend This course is intended for anyone responsible for operating, maintaining and optimizing the performance of a Symmetrix Storage environment.   Course Certifications This course is part of the following Certifications:   Prerequisites
