that very well may be true, but in my environment, it is not what I did, it is what I inhertited. If I could take down the production servers and do cable management it really would make my life a lot easier.
When the datacenter moves in 2010 I have a chance to do just that.
In the interim as systems get powered off or have issues, we try to move them to a newer rack where we have cleaner cabling.
