Avoiding Spaghetti Syndrome: Managing your Data Center’s Cabling

Tom Bennett IT Manager
Published on June 12, 2014

It's important to keep your data center organized, including the cables that connect everything together. Here are some tips for managing your cabling infrastructure.

Data centers are complicated. With dozens of servers tightly packed into racks, it’s important to make sure they are organized. The cables connecting these servers into your network are an aspect of a data center that can quickly grow out of control, and the last thing you want to encounter is a tangled mass of cables that make it impossible to determine how servers are connected. Here are some tips we’ve put together to help you make sure your data center isn’t going to be compared to a bowl of spaghetti anytime soon:


First and foremost, you should come up with a plan that meets the requirements of your data center and the systems in place. If you don’t take the time to plan your cable installation correctly the first time, it can cost you in the future. When you’re planning your cable installation, make sure to prepare for future growth and for new technologies. New technologies may require additional bandwidth, so make sure you take that into account when choosing which type of cabling to use. Whether you’re planning to cable a new data center or expand your existing data center, here are a few things you may want to consider:

Use a Structured Approach

A structured cabling approach is the groundwork of your premise’s network infrastructure. It is the platform upon which all your information technology systems are built. Data centers consist of highly consolidated network cabling and equipment, and this high consolidation requires high density structured cabling systems. Using a structured approach allows you to define the cable routes and pathways for different types of cabling, which will help if you ever have to install additional cabling in the future. If planned and implemented correctly, this approach should not affect air flow within the datacenter, and it can also help with identifying cables and reducing time spent troubleshooting cabling issues. By taking a structured approach when installing cabling, you will be able to reduce future maintenance costs while minimizing workflow disruptions and network downtime.

Labeling and Documentation

Another important aspect of managing your data center infrastructure is implementing a labeling scheme that allows you to easily identify where a cable is going. The labeling scheme should be implemented throughout your data center infrastructure. A good labeling scheme should identify where the cable is going from both ends and, depending on your scheme, identify the device it’s connecting to. Implementing a labeling scheme will reduce the time spent troubleshooting infrastructure issues, and it can possibly reduce downtime as well. Without a labeling scheme, troubleshooting and tracing/toning out cables can be very time consuming and costly. An effective labeling scheme in the data center can reduce maintenance time in the event of moves, adds, or changes. There are many different labeling tools and label types to choose from. Make sure you choose an industrial grade labeler and labels that can endure your data center’s environment. Keeping and maintaining labeling documentation is one of the most important aspects of implementing and maintaining a labeling scheme; this information should be clearly documented and backed up to ensure it’s always available.

Policies and Procedures

Every company is going to have different policies and procedures in place to help manage and maintain their data center infrastructure. Documenting these policies and procedures helps provide information to other employees to make sure everyone is on the same page when it comes to managing your data center infrastructure. These policies and procedures should provide an outline or checklist of what needs to be done in the event there are any changes to the cabling infrastructure. This will ensure that you data center infrastructure stays neat and manageable.

There is a lot more that goes into managing your data center infrastructure. If you need any additional information on structured cabling and codes, these are some of the organizations that develop the standards related to cabling and communications:
