Always liked the work my fellow coworkers at Globix used to do - I don't have any shots of SJC or NYC online (too bad - a few projects I went to alot of trouble on to show the rest how it should be done ;) ), but here's one of our demo panels from LHR:

And yeah, most of what was under the floors in all the DCs looked like that, and yeah I hear for strict cat5 regs that they shouldn't be velcroed together like that. Wire wraps were never used (only velcro), bundles are laid down so that shortest is on the bottom side, longest on the top.
Now, we've seen a few pics of "good" cabling as well. However, I'm forced to ask which kind of "good cabling" is possible in a dynamic environment when you plug in/out, change, etc. the cables. This seems to invariably lead to total chaos :-). For example, consider the case of a patch panel of 200 plugs, where you'd have to wire cables to 20 different physical locations (where the switches/routers are)? How do you manage that elegantly, at the patch panel side and the switch/router side? :-) I mean, it's fine if you take 100 cables, and wire them between the patches and the switches (or the racks if you have the patch cross-connect there) in bulk, but consider the case where you have 15 different switches (different subnets), a computer moving in/out of the room in a daily basis etc. You can't just go around wiring like http://thrashyour.com/lhr1-wiringdemo.jpg or http://new.onecall.net/timages/cat5patch.jpg How do you do good cabling in dynamic, real environments? :-) -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
