Especially when you choose 4u colocation for your expanding business, you can get a great peace of mind that cannot be attained with the traditional data center. Therefore, Server colocation experts compiled a brief guide that can help you understand everything about 4u colocation for your business.

4u colocation

What are 4u colocation and 4u racks?

4U colocation is the most preferred solution to today's business owner. Especially if they want to expand the business, they will choose this colocation type for better features and bandwidth. When it comes to placing servers in the 4u racks, you will come to know that these data cabinets have a small height and size available in the data center environment. 

All the 4U racks and cabinets look like an ideal solution when you have the smallest amount of hardware to place in the rackmount and can use in different IT environments. These racks have a solid and flexible design which suits best for desk or floor standing. These are specifically manufactured from steel material and also a powder-coated solution. You can also choose rack color options according to your business needs. It’s important to note the difference in their depths and sizes.

4u colocation rack guide:

While selecting a rack or cabinet for 4u colocation, consider these factors.


4u rack height:

A 4U rack space can simply allow you to house your server into the Rackspace with no more height than 7inches or 1.78m while placing it onto the rack with a 1U server or 44.45mm. Therefore, you need to take special care of the server and rack size and make sure that your server rack is already capable of housing a server with that suitable size. If you are placing any IoT device or other networking hardware, then these measurements are important to consider as well.

4u rack width:

When you are choosing colocation server hosting for your hardware or equipment, then it’s better to measure the width in an efficient manner. Remember, the standard width of the rack is 19inches or 482.6mm and most of the cabinets are generally available around 600mm or 800mm width. 

Now, most of your hardware or products can either fit their front rack space with the help of cage nuts onto flanges and are attached to your rack-mountable device. Sometimes it may attach to the rails going from its front to the back pillars or even sitting on the internal shelves as well as the slide-out trays. There should be enough room left in the rack to maintain sufficient airflow and easy access.

Rack depth for 4u colocation:

It's also important to measure the depth of the 4u cabinet. It basically ranges from 600-1200mm. You should take special care while choosing the rack depth as it ensures it is suitable and long enough for your server to be housed including all the essential space for cables as well as connection access. Now the question is, how will you manage all the cables for different rack sizes so that you can easily identify cable and then avoid all types of serious accidental disconnection. That’s the reason, people consider multiple significant factors for server colocation so they can easily operate their business without any distraction. 

Open or closed racks:

You must know that the majority of the server racks, as well as data cabinets, are carefully enclosed as opposed to placed in the open frame. Therefore, the enclosed cabinet which has a front door, back door, and side panels will be comparatively more secure and may offer highly efficient airflow management. That’s why rack colocation experts suggest that choosing an enclosed cabinet with proper doors and size measurements can better guard your servers as compared to placing the servers in your office premises without such additional security measures.

What are the benefits of choosing 4u colocation?

There are a lot of significant benefits associated with 4u colocation. Some of them are highlighted below:

  • Remote hands:

When you choose 4u colocation for your server, your equipment will be housed in secure hands which are working remotely and providing efficient performance 24 hours. When your server is in the remote hands, engineers can easily perform any technical task in case of any problems. They can make memory upgrades, reset your server, and hard drive upgrade.

  • 99.9% uptime:

Most data centers promise 99.9% uptime guarantees to their customers, which ensures that the server will be available 24 hours without a single minute of downtime. This strategy is building more confidence in customers and they are trusting 1u and 2u colocation services to streamline the operations of their small business.

  • Physical security:

Data centers offer more physical security to your servers as compared to traditional solutions. You won't be worried about the storm, floods, earthquakes, or other uncertain happenings. Your servers will be placed securely from all the troubles.

  • Budget compatible:

Many business owners consider colocation because this is the most budget-friendly option as compared to others. If you calculate the overall costs which include network, bandwidth, electricity, hiring of new professionals, and other resources, you will find out that these costs are higher when you choose office premises for colocation. They are even higher than your business revenue. 

Bottom line:

So once you choose a 4u colocation solution for your business, you would find out there are thousands of advantages that can offer long term results. Choosing 1u, 2u or 3u colocation also offers the same benefits but maybe they are not good for expanding businesses. If you are stuck in finding the best solution, you can also consult with Server colocation experts as they can suggest something better according to your business needs.
