Ask the Expert: FSPF Concepts and Troubleshooting in Cisco SAN Environments
With Upinder Sujlana
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about FSPF, VSAN interaction, load balancing, and troubleshooting with Upinder Sujlana.
According to the FC-SW-2 standard, Fabric Shortest Path First (FSPF) is a link state path selection protocol. FSPF keeps track of the links on all switches in the fabric and associates a cost with each link. FSPF tracks the state of links on all switches in the fabric, associates a cost with each link in its database, and then chooses the path with a minimal cost. The cost associated with an interface can be administratively changed to implement the FSPF route selection. Upinder will discuss Cisco's implementation of FSPF.

Ask the Expert: FSPF Concepts and Troubleshooting in Cisco SAN E
let me mention first that I don't know anything about FSPF. Actually, this is the very first time I've seen this abbreviation. Even more, I was pretty sure that there are no routing protocols in the Fiber Channel world. Now, when you have some idea about my level of knowledge, can you please try to explain in few simple words what is the benefit of using FSPF, why (and when) it was created and is it by any chance important in UCS server world.
BTW, I also tried to dig up some info on my own but only useful link (that one you already posted) doesn't display any pictures:
