The standard width of a mountable server rack established by the Electronic Industries Alliance (EIA) is 19 inches. Technically, this 19-inch measurement refers to the width of the front panel of the mountable module that slides into the rack, while the actual server chassis width needs to be less than 17.75 inches to fit within the frame.

While not a hard requirement, most manufacturers, including Pure Storage®, adhere to the 19-inch rack width for their servers to avoid compatibility issues.

While the width of server racks is fixed at 19 inches, the height and depth of modules can vary considerably depending on what you’re trying to install in the data centre rack. While depth is not standardized, common depths range between 24 inches and 48 inches. The reason for this depth is likely because the standard floor panel in a data centre is 24 inches by 24 inches. Height is typically measured in standardized rack units of 1.75 inches per U. A good rule of thumb when considering how much space you have in a rack for a server module or accessory is how many units it takes up.

Let’s go over some common questions people ask about server rack sizes:

What is a 1U Server Rack?

The most basic unit of height for a server rack is 1U, which is equivalent to 1.75 inches. As the smallest unit, this size gives you the most versatility when outfitting your server rack stack.

What is a 4U Server Rack?

A 4U rack is only 7 inches high. With four units, you have enough room in a 4U server rack to accommodate a decent-sized server chassis and accessories such as power and cooling. This makes the 4U server rack great for personal use or a small office.

What is a 6U Server Rack?

A 6U server rack is 10.5 inches high. This is the standard size of wall-mounted cabinets and fly racks. While still small, these cabinets are right at home in the small business data centre.

What is a 42U Server Rack?

With 73.5 inches of rack mount space, the 42U server rack is the most common rack height utilized in the data centre. Industrial data centers will have rooms filled with 42U cabinets lined up in rows. It’s one of the most efficient ways to pack processing power and capacity in a small space.
