ONTAP Performance Analysis (PERFCDOT) – Outline

Detailed 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

Labs
  • Identify the exercise environment
  • Log in to the exercise environment
  • Add a cluster to OnCommand System Manager
  • Configure SNMP public community name
  • Identify clustered Data ONTAP components
  • Set the clustered Data ONTAP command line system timeout value (optional)
  • Examine the statistics catalog commands
  • Examine the statistics start and statistics show commands
  • Defining workload characteristics
  • Perform initial health checks on the cluster
  • Baseline performance monitoring from the cluster shell
  • Performance monitoring from the cluster shell
  • Unlock diag userid
  • Using the performance and statistics collector (Perfstat)
  • Reactively limit thoughput to a workload by associating the workload with QoS policy group
  • Proactively monitor workload performance by associating a workload with a QoS policy group
  • Isolate a tenant workload by associating the workload with a QoS policy group
