We often talk about the importance of network cable management in data centers, and how important it is to efficiency, airflow, equipment longevity, and more. But what about on managing cables on the rack itself?

In fact, we know (because you’ve told us) that nearly everyone has encountered the “spaghetti mess” at some point or another. This is a bad thing, not just because of how it looks, but because of the possible damage, lack of efficiency, and even increased maintenance costs.
But there are solutions, and if you understand the essentials of rack cable management, things can be pretty simple for you. You don’t ever have to look at the “spaghetti mess” in your data center again.
Let’s start at the beginning:
The Server Rack Itself
First of all, we all know there are different kinds of racks and different sizes. While improving technology means some things are getting smaller, server components are actually getting larger. That means that wider racks, on the order of 23” cable racks or wider are more common. You can’t use a 19” cable rack for a 23” component. The end result will not only be ugly but could be disastrous.
In addition, racks, specifically in California but in other locations as well, must be built to withstand earthquakes and other natural disasters. It’s a pretty major requirement, and even if you aren’t in California, there may be state or local ordinances that cover the kind of racks you can use in your data center. The rack is the foundation for a good rack cable management system.
Racks also come in different levels of quality. Always remember that cheap is probably cheap for a reason. You want racks to not only be the right size, but to be sturdy and reliable. Cheap racks that bend, fit together poorly, and that don’t work well with standard adapters and rack cable managers will end up costing you more in the long run. Make sure you have the right rack for the right job.
Rack Cable Managers
Rack cable managers, sometimes called horizontal lacing bars, are a critical part of cable management. There are a number of varieties, both horizontal and vertical. They are often classified by the amount of space they take up on the rack.
For example, our ZeroU rack cable management systems doesn’t take up any rack space, allowing you to be more efficient with the use of your space, reducing the overall footprint of your servers. This means using fewer racks and leaving more space for airflow.
A good rack cable management system also gives installers and maintenance personnel space to work. They have room to get tools and their hands in where needed, meaning they can work faster and more efficiently.
Bundling and Labeling
Bundling like cables together keeps your racks looking neat, avoiding the spaghetti mess look. But it does more than that. Running like cables together reduces electromagnetic interference, makes finding what you are looking for easier, and again reduces maintenance time.
Bundling can be done with zip ties, and while sometimes that is appropriate, most often Velcro is a better solution. It’s reusable, can be loosened or tightened as needed when doing adds, moves, and changes.
The other important essential? Labeling. When was the last time you thought, “I wish I (or someone else) had labeled that?” When troubleshooting and executing repairs, a simple label can reduce the time needed to sort through cables exponentially. Also, if you properly and accurately label cables, you are less likely to forget where they should be terminated. They are less likely to get tangled as you install them, allowing you to avoid the spaghetti mess.
Cable Length and Rack Cable Management
Another simple way to avoid the Spaghetti mess? Be sure your cables are cut to the right length and terminate them appropriately. Network cables that are too long are much more likely to tangle or get wrapped around one another.
The key is simply following the old carpenter’s rule: measure twice, cut once. You don’t want cables to be too short either. This can result in sharp bends and even breakage, and those things can result in data slowdowns or worse, failures.
Have a Rack Cable Management Plan
What is the most important element of efficient rack cable management and avoiding the spaghetti mess? Having a plan and having everything on hand that you need. Whether you are renovating and updating your data center, building a new one, or replacing old components, develop a plan.
- How Many? – Determine the size and number of racks you will need and order them ahead of time.
- Plan Ahead – Develop a plan to manage cables and order the horizontal rack organizers you will need – and vertical racks!
- Network Cable Requirements – Determine the amount of cable and the type you will need. Order them ahead of time, but also make sure you have the terminals you will need on hand.
- Velcro! Need we say it again? – Make sure you have more than enough Velcro cable ties on hand to bundle cables as needed.
- Colored Zip Ties – While not always the best solution (see Velcro) overall, zip ties still have their place in rack cable management. Have plenty on hand to aid with cable routing.
- Cable Labels – have plenty of custom labels on hand and use them. Make sure every installer is on the same page as far as the way things will be labelled.
A plan will keep the spaghetti mess from developing in the first place, saving you hours later on.
