And I wouldn't be surprised if ferrets did run this server. They used to use them to run wiring down the ducts in large airplanes .
I heard a story once about the Pentagon. They were trying to run new electrical cabling in the building, and since it's pretty old, they were having difficulty getting the cabling into some of the narrow areas that were built before dropped ceilings became the norm for offices. They were about to start tearing apart walls and ceilings when a Colonel happened be and noticed what was going on.
He went home and got his pet ferret. They secured a cable bundle to his harness and the Colonel went to the other end where they wanted the cables to come out. They released the ferret and the Colonel called him, and sure enough, he wound his way
through the narrow spaces and delivered the cabling to the destination. And saved the DoD many thousands of dollars.
I don't know if this story is true, but it's neat.
