Our workstations are connected to a fiber router with dual gig-e ethernet. The router goes to our video storage server via fiber. It's way faster to copy a file over to the storage than it is to copy it to another SATA drive... I have no idea how it's configured, but it's fast.

The setup for Final Cut Server is pretty complicated and like most databases, it's got to be right from the beginning. The documentation at the time we installed it was not very thorough.... you need a pro to set it up.
