NetApp

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
