The Performance Analysis on Clustered Data ONTAP (NA-PERFCDOT) course provides you with the knowledge and skills that you need to collect and analyze system performance data from NetApp storage systems that are running clustered Data ONTAP. Prepares you on how to interpret data and how to identify and implement changes that improve system efficiency. Covers how to use system commands and features to monitor and enhance storage system performance using a combination of hands-on labs, case-studies, and technical discussion.

Upon completion of this course, students are able to:

  • Describe how data flows through the network and protocol layers of clustered Data ONTAP
  • Define performance-related terms and describe basic methodologies
  • Identify the methods that can be used to monitor and analyze storage system performance
  • Explain how methods and tools can be used to collect performance data
  • Use command output to analyze system performance Use command output from case studies to identify performance bottlenecks
  • Implement configuration for recommended practices for resiliency and performance
  • Locate resources and information that help you maximize system performance

Course Outline

Module 1 How a NetApp Storage System Works

  • Describe the layers within the Data ONTAP architecture List the advantages that are provided by the ability of WAFL to optimize writes
  • Explain the purpose of NVRAM
  • Diagram the flow of read and write requests through the network and protocol layers of Data ONTAP
  • Describe the benefits that RAID provides

Module 2 Performance Overview

  • Define performance-related terms, such as “baseline,” “bottleneck,” “Little’s law,” and “latency”
  • Describe baseline performance guidelines and methodologies as they relate to NetApp storage systems

Module 3 Clustered Storage System Workloads and Bottlenecks

  • Gather information about the workload of an existing storage system
  • Identify the storage system components that can affect performance—become bottlenecks

Module 4 Cluster Performance Monitoring and Analysis

  • Describe the performance analysis tools and commands that are commonly used for cluster health checks
  • Identify the key performance commands and describe the command output that they produce
  • Explain how to use NetApp tools for performance measurement
  • Describe the benefits of using the AutoSupport support tool for performance analysis

Module 5 OnCommand Management Tools

  • List the three categories of performance tools Explain the features and functions of Insight Perform
  • Explain the features and functions of OnCommand Balance
  • Use OnCommand management tools to view performance data

Module 6 Storage QoS

  • Discuss how the Storage Quality of Service (QoS) feature works in a clustered Data ONTAP environment Identify the commands that are used to manage policy groups
  • Monitor workload performance
