For the past six months we've been having performance issues on our network. Last month I thought we tracked down the problem to network cabling issues. Initially when we replaced the cheap cat5e cables we had with Cat 6 cables on two of our Vmware Vsphere servers the performance issues went away on those two servers. However, when we replaced the cat5e cables on our SAN arrays the performance issues returned (even though all were running Cat6).
I did some research online and found a couple sites that mentioned Cat6 cables are more prone to interference from power cables that are in close proximity to the network cables. Our racks are setup with power cables and network cables (Cat6) running in the same cable management channels. I need expert documentation proving this could be an issue before we can proceed with the next step of re-cabling our racks or purchasing shielded Cat6 cables.
Can anyone tell me if it is a problem having Cat6 and power cables in the same cable management channels. If so, can you provide documentation stating this?
