What Is The Standard Server Rack Size?

What is the standard server rack size?

When organizing a data center or small home office, everyone needs furniture to house networking equipment. No matter how big your system is, a special, durable body is still made for IT hardware.


The modern industry offers a wide range of models for any type of data center. They vary in design and size, from compacts for desktop installations to larger models for larger data centers. It is important to choose the best size furniture to accommodate all the required equipment, and wiring and allow free space for air circulation.

Server furniture dimensions

IT hardware is used to store data and process computing tasks. A system can scale from a dozen to a hundred active devices in total. Therefore, when choosing the right model for all equipment, system administrators should consider the following server cabinet dimensions:

high

For unskilled users, this dimension may be unclear. In system administration, heights are identified in units (U). Typically, it's specified as 12U, 4U, or 48U in the spec. 1U is equal to 1,75 inches. To calculate the height of the cabinet in cm, the user should multiply by 1,75*12/4/48/etc.

Wall-mounted furniture is usually smaller in size, while floor-standing furniture is many times larger.

width

This dimension does not cause problems. Modern manufacturers produce models with standardized widths. The 19-inch model is the most common choice. There are also 24 products. Choose this width to accommodate all modern equipment and secure the equipment to the rack.

depth

This size is variable and ranges from 0 to 50 inches. However, the most common sizes are 24 and 48 inches deep. When working with racks, the depth can be adjusted as needed as the columns can be reassembled.

Cabinets with a depth of 23-31 inches are suitable for small equipment such as switches and patch panels, and cabinets with a depth of 40-47 inches are suitable for servers.
