Cable Management: Keep it Neat

Does the backside of your server rack look like storage for a waterfall of cables? Keeping cables under control can be a major task, but it should be a high priority.

Most server racks are designed to accommodate cables in a certain way and provide channels for routing. There are also aftermarket products such as "Neat Patch" to assist with management. Some cable management may actually be a burden, such as server swing arms. These arms are designed so the server can be pulled from the rack while still powered on. This may seem like a good idea, but moving a powered on server with fragile drives spinning at 15,000 RPMs is not recommended. Servers should be powered off before moving. These arms also trap massive amounts of heat and restrict exhaust airflow.

How can I get started?

  • All cables should be properly labeled on each end.
  • Color code cables by function
  • Keep power and data in separate channels where possible
  • Remove out of use equipment
  • Zip tie or Velcro extra cable in loops (not too tight)
  • Remove cabling server arms

Why should I care?

  • Easier to troubleshoot cable issues
  • Easier to replace equipment
  • Reduces heat and improves air flow
  • Reduce the risk of a power wire arc and fire
  • Professional pride

If you would like to soothe my cabling OCD, I would be more than willing to help.
