Re: an over-the-top data center

pardon me for resurrecting this topic... For sites that are built in caves, how do they deal with cabling ? In the pretty pictures of the swedish site, there didn't seem to be an obvious raised floor. And it appeared to be solid concrete floor between the wings containing the systems. And no massive cable risers or suspended cable paths. It is all nice if neat, but in real life, wouldn't they need to be stringing tons and tons of cable ? Or it is a case of the pretty pictures with the fog having been taken with empty racks, before the data centre was outfitted with real equipment and now, there would be cables everywhere ?
