Fibre Channel, part 1: FCP and WWPN addressing

- In this lecture, you'll learn about fibre channel,…which is the original SAN protocol,…so it's the best place to start learning about SAN.…All the other SAN protocols came after fibre channel,…but a lot of the same characteristics,…so it really helps if you understand fibre channel first.…There's quite a bit to it, so I'm going to break it down…into three separate lectures,…and we'll start here talking about FCP,…the fibre channel protocol,…and fibre channel addressing which uses WWPNs.…

(techno music)…The first thing to learn about SANs is the terminology.…We covered in the earlier lecture what NAS and SAN are.…NAS is file level access…and SAN is block level access.…Meaning the client that is accessing the SAN storage,…it appears to be accessing a hard drive directly.…

When you configure storage on a storage system…for the client you create a LUN.…That stands for logical unit number.…And that represents a disk that's going to be…presented to the host and it appears to the host…just the same as a local hard drive inside its own chassis.…
