Agenda:

The content is based on the current official NetApp™ course materials for the "ONTAP Performance Administration" course and is supplemented by the instructor's 27 years of ONTAP experience, corresponding additional commands, and even deeper interpretations and checklists.

Building a NetApp™ Cluster
- Operating System Layers
- Data Flow in the Cluster
- Troubleshooting Configuration Errors (Hardware and Software)
Introduction to Challenges
- Physical Limits and Additional Efforts for Error Prevention or Correction: Latency and Response Times, Fragmentation, Misalignment, Small IOs, Reconstructs, Silent Data Corruption
- Fairness Brakes in NAS and SAN Protocols and ONTAP Management Layers: TCP Window Size, Buffer Credits, Quality of Service, CMD Queue Limits
- How can we recognize them?
- What is their impact?
Introduction to NetApp™ Countermeasures
- Lost Write Protection, DIF/DIX=PI, WAFL Write Optimization, RAID-DP/TEC, Free Space Reallocate, Read Reallocate, Read Ahead, Dedupe, Compression, Compaction, VAAI, ODX, Thin Provisioning, Quality of Service, Volume Move, FlexGroups, InodePath
The Mathematical Foundations
- Queueing Theory and its Concrete Application in Storage and Network Performance Analysis
- Recognizing Open and Closed Load / Single-threaded and Parallel Workloads
- Criteria for Identifying and Distinguishing Bullies and Victims
Introduction to Commands for Identifying
- Highest Latencies
- Highest IO Loads
- Highest Data Throughputs
- Largest Queues
Performance Tuning
- HDD + PAM = Flash Cache
- HDD + SSD = Flash Pool (Hybrid Aggregate)
- All Flash FAS (AFF)
- FlexGroup
- Optimizations: Which are compatible? Which cancel each other out?
Sizing
- Adequate Consideration of Client IO Workloads
- Estimation of Additional Housekeeping and Metadata IOs
- Size of Metadata and Working Set
Overview of Additional External Monitoring Tools
- System Manager
- Active IQ Unified Manager
- Harvest, Graphite, Grafana, NABox
All topics of the official NetApp™ training "ONTAP Performance Administration" are covered and deepened:
- Describe how to use NetApp™ tools for performance measurement
- Explain the benefits of using Active IQ for performance analysis
- Use Active IQ Unified Manager to monitor the performance of cluster objects
- Describe the layers of ONTAP software architecture
- Diagram the flow of read and write requests through the ONTAP network and protocol layers
- Use performance analysis tools to identify WAFL-related performance bottlenecks
- Discuss how storage quality of service (QoS) operates in an ONTAP environment
- Explain how to monitor and manage workload performance
- Use performance analysis tools to identify NAS performance bottlenecks
- Identify the actions that you can take to resolve SAN performance issues

Objectives:

The course ST230c Performance Administration on CONTAP imparts the capabilities of performance optimization in NetApp™ ONTAP clusters. It covers the limits of the utilized hardware and software, the tools for performance analysis, the interpretation of measured values, and the resulting optimization possibilities and their impacts.

Target audience:

Experienced NetApp™ Storage Administrators and Architects

Prerequisites:

To effectively follow the course content and pace in the training ST230c Performance Administration on ONTAP, we recommend attending the following trainings in advance:
ST200c ONTAP 9.x Admin Basics
ST217c ONTAP 9.x - NAS Advanced incl. Troubleshooting

At least 6 months of experience with ONTAP administration is absolutely necessary.
