Fibre Channel, part 4: Redundancy and multipathing

“

- This is the fourth and final part of the Fiber Channel videos. Here, you'll learn about redundancy, and multipathing. (pumping electronic music) Servers' access to their storage will pretty much always be mission critical for that company, so the systems should be built with no single points of failure. Redundant Fiber Channel networks will be put in place, and they're known as Fabric A and Fabric B, or they can also be known as SAN A and SAN B. Each server and storage system host will be connected to both fabrics with redundant HBA ports, so that gives them two possible paths at least to get to each other. Fiber Channel switches distribute shared information to each other such as the domain IDs, the FCNS database, and zoning, as you learned in the earlier lectures. If an error in Fabric A was able to propagate to Fabric B, or vice versa, this would bring down both fabrics and drop the servers connection to their storage, so it's really important, we don't want a problem on both…
