NetApp - Performance Analysis on Clustered Data ONTAP (NA-PERFCDOT)

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
