The Performance Analysis on Data ONTAP (NA-PAD) course provides you with the knowledge and skills to perform data collection and analysis on NetApp® storage systems. You will learn how to interpret data and apply performance changes based on their analysis. This course also covers using analysis data for tuning and monitoring performance.

Upon completion of this course, students are able to:

  • Recognize performance terminology and basic methodology
  • Use known methods and tools to collect performance data
  • Describe the Data ONTAP architecture and the benefits of features such as NVRAM and the WAFL® (Write Anywhere File Layout) file system
  • Use knowledge about how data flows through the network and protocol layers of Data ONTAP to monitor and analyze storage system performance
  • Examine command output from case studies to identify performance bottlenecks
  • Perform basic software configuration and recognize diagnostic operations for the Performance Acceleration Module and FlexScale
  • Use FlexCache™ to improve NFSv2 and NFSv3 read performance
  • Use the reallocate command to measure volume or file layout and optimize the layout when appropriate
  • Implement configuration for best practices for resiliency and performance
  • Identify where to find further information

Course Outline


Module 1 Performance Overview

  • Define performance terminology
