Netapp ONTAP WAFL explored

A closer look at the WAFL environment and performance
Created byPeter van der weerd

What you'll learn

  • Students will have a good working knowledge of WAFL's features and functions.
  • A lot of topics will be discussed and lots of demos will be given.
  • And we will look at tools to monitor performance, like sysstat, statistics
  • Most of the texts will be available in pdf from the resource section so you read afterwards if things were too fast (I hope not).
  • WAFL will be explored in great depth, but also common features like deduplication, flex clones, compression, compaction, will be dealt with.

Course content

7 sections • 17 lectures • 3h 14m total length

  • WAFL is more than a filesystem.13:21

    This section will describe what WAFL is.

  • WAFL is more than a filesystem, demo.3:52
  • WAFL is more than a filesystem.

Requirements

  • Students should have a practical or at least conceptual knowledge of how Netapp Clusters work in general.
  • This is a somewhat advanced training that presupposes some administrative experience.
  • Knowledge of filesystems is not necessary, but would be beneficial.

Description

This training gives an insight into how Netapp's filesystem environment works. You will get an overview of what happens to client data from when it enters the cluster to when it is stored on disk. It will deal with inodes, pointers, blocks, snapshots, writes, efficiency, etc.

The second part of the training will focus on performance of the WAFL environment. We will discuss and demonstrate command-line tools like statistics, statit, sysstat and stats. Also we will have a look at quality of service. And the training will end with the download, installation and configuration of NAbox and On Command Unified Manager.

There will be theory as well as demonstrations. All of the texts are offered as downloadable PDF.

By the end of this training, students should have a good understanding of how WAFL works and they will also have a working knowledge of the different performance tools that are available.
