Netapp ONTAP WAFL explored udemy course
A closer look at the WAFL environment and performance
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.
