Server Racks & Cabinets

U space, or rack units, are a standard by which height in racks and IT equipment is measured by. This metric is based off of 3 rack holes which add up to 1.75 inches. 

You need to be familiar with how much U space your equipment will take up in order to save money while making sure everything fits. If you end up with too much open space, you might need blanking panels to keep airflow contained. 

We carry racks with U heights from 1U to 90U, meaning that there are plenty of options for the home, office or data center.

Depth is just as important as U space because not having enough room means that you might be returning or reselling your rack. When considering necessary depth, you will need to not only find the dimensions for your current hardware, but any hardware that you might get in the future. 

RackSolutions’ server racks range from 0-50 inches. The average depth for a server rack is about 36”. On top of making sure there is enough depth for your equipment, make sure that any rails or shelves you would like to use are compatible. 

Most server chassis have a width of 19 or 23 inches in order to keep things consistent. On our website, width is filtered by which server chassis the rack can fit. 

External width is relevant to the space that the rack takes up inside of a room. It can extend up to 32 inches to provide space for cable management, power supplies and other accessories. This can be customized more through individual item pages. 

To summarize, check the width of your equipment to determine your internal width and your floor space for the external width.

All of our racks have static load capacity ratings on their product pages. You will need to estimate the sum of your equipment's weight in order to determine what capacity your rack will need.

Purchasing a rack with a higher load capacity than necessary is recommended. One reason is because racks that are capable of being moved have lower weight capacities while in motion. Additionally, it is impossible to predict future weight needs and racks can last much longer than the equipment itself.

2 Post racks, also known as telco or relay racks are built to house lightweight equipment. This includes routers, switches, controllers or very thin servers. Additionally, 2 post racks are great for mounting shelves that support non rackable equipment. 

You can also mount servers on 2 post racks as long as the cumulative weight falls within capacity. We offer plenty of adapters and hybrid rails to help mount servers in 2 post racks.

4 Post racks are the standard for full servers. They can support thousands of pounds, reach 70U in height and fit any kind of IT equipment that needs to be mounted. 

If you need extra security, expandability or a high weight capacity, open or enclosed 4 post racks are the best option. You can purchase them in sizes small enough to fit in an office and large enough to satisfy a data center.

Both 4 Post and 2 Post racks have open frame options. This means that all sides of the rack are open to the environment around them. Open frame racks are less expensive than enclosed frame racks, but sacrifice security. 

If you want easy access to maintenance, unobstructed airflow and aren’t worried about equipment being tampered with, open frame racks are the most cost effective.

Server Racks that are protected from all four corners are called “enclosed frames.” These are available with locks one or two locks on the front, back or both. 

Because of the extra metal, enclosed frame racks are a bit more expensive and allow less airflow. The walls allow for more cable management, fans and sensor accessories to be mounted.

Our server racks are compatible with all leading OEM servers and equipment, such as Dell, HP and IBM. Open frame racks allow for more airflow and space while enclosed racks enhance security. You will likely want a 2 post (telco) rack if mounting lightweight equipment and a 4 post rack for full sized servers. 

Check the height, width and weight requirements of your equipment before making a purchase. Dimensions of our server racks can be found on specific product pages.
