This course enables you to collect and analyze system performance data from NetApp® storage systems that run NetApp ONTAP® 9 software. You learn how to interpret data and how to identify and implement changes that improve system efficiency. You also learn how to use system commands and features to monitor and enhance storage system performance. You learn from hands-on exercises, case studies, and technical discussions.

• Describe how to use NetApp tools for performance measurement
• Describe the layers within the ONTAP architecture
• Diagram the flow of read and write requests through the network and data layers of ONTAP software
• Discuss how storage quality of service (QoS) operates in an ONTAP cluster
• Explain how to monitor and manage workload performance
• Use the performance analysis tools to identify NAS and SAN performance obstacles

Professionals who manage NetApp storage systems and would like a deeper understanding of Clustered Data ONTAP system performance

Hands-on experience with ONTAP software (6 months to 12 months) is required in addition to the OT-CLU-DPA instructor led class..
