A rack unit (abbreviated as U, less commonly seen as RU) is a unit of measurement applied to equipment racks and the servers, disk drives and other devices that they contain. One U is 1.75 inches (44.45mm); the standard rack, at 19 inches, is 42U.42 servers
However, the most common server rack size you'll encounter in data centers is 42U. A 42U rack is one designed to accommodate 42 servers (the "U" stands for "units," which in this case refers to servers).Question：What is the size of the 42U cabinet Answer: 42U can be a server cabinet with a height of 2 meters, a width of 0.6 meters and a depth of 0.8 meters, or a server cabinet of 2 meters, a width of 0.6 meters and a depth of 0.96 meters; Question 2: How many servers can be placed in a server cabinet

How much is 1U in a rack
1.75″
One rack unit (1U) is 1.75″ (44.45 mm) of vertical space, or typically the equivalent of three rack hole spaces tall. One of the first criteria to consider when purchasing a rack is how many RUs your equipment requires.
What is the difference between 48U and 42U : 42U racks are also extremely common. They are smaller than 48U racks but provide enough space for small and mid-size data centers. Many 42U products have 19-inch-wide server racks. Most pieces of rack-mounted equipment are 19 inches wide, so they will fit snuggly into your racks.
Servers come in sizes of: 1U, 2U, and 4U. While server sizes may differ slightly depending on the make and model, a 1U server typically occupies a dimension of 1.75″ by 19″ of rack space. There are also 2U and 4U servers, which offer more computing power but take up more space on the rack. The Equipment Found in a Server Rack
