Learn SAN and NAS storage basics.

You can learn about Storage Area Network and Network Attached Storage storage basics with the training videos on this page. I’ve also included full explanations with text and screenshots. The videos are mainly designed for systems or network engineers who want to understand the theory of how SAN and NAS works. I’ve included practical examples so you can also see how SAN and NAS are implemented in real-world deployments. You could also find the content useful if you’re studying for a storage certification such as the CompTIA Storage+ or SNIA Certified Storage Professional.
