With network cables it is easy. I use velcro-ties, coloured cables, 0U vertical cable organizers from APC on side of the rack -- easy and neat.
However with power cables it was always giving me headaches.
With some of the racks I am using Vertical PDUs from APC (0U) so it's kind of neat as am getting 0.3m/0.5m cables and connecting them to servers which are close to the PDU sockets. It's kind of neat, but it could be better.
With horizontal PDUs it is really bad -- no matter how hard I try there is always few cables that are too long and are hanging loose below the APC.
Eg. http://www.flickr.com/photos/92011471@N00/25695150/ -- this will cause the cables on the bottom to be different length and its going to get quite messy...
What are best practices for power cabling? How do you guys do this so your cables once put in once are neat and you don't have to worry about them for years? Do you also cut them to match right length? Do you use some special organizers? Or maybe you know some tricks like hiding them between the side of the server and rack?
I went through many many posts on SF however most of the are oriented around network cabling and very few are touching slightly on the power problem.
Of course I am talking about having network cables on one side and power cables on the other side.
Any suggestions, recommendations, suggestions much appreciated.
