Rack with sample component sizes including an A/V half-rack unit. A rack unit (abbreviated U or RU) is a unit of measure defined as 1 + 3 ⁄ 4 inches (44.45 mm). [1] [2] It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed ...

A standard 19-inch server rack cabinet is typically 42u in height, 600 millimetres (24 in) wide, and 36 inches (914.40 mm) deep. [18] This comprises a volume of 974 L, or just under a cubic meter. Newer server rack cabinets come with adjustable mounting rails allowing the user to place the rails at a shorter depth if needed.
Rack Rail comes in two different commonly used forms. Tapped/threaded rack rail has round holes tapped for 10-32 UNF or 10-24 UNC screws. The other common form of rack rail is square hole rack strip which has square holes for captive nuts, available tapped for various different screw threads, that are clipped into the holes as needed to mount equipment.
The most common computer rack form-factor is 42U high, which limits the number of discrete computer devices directly mountable in a rack to 42 components. Blades do not have this limitation. As of 2014, densities of up to 180 servers per blade system (or 1440 servers per rack) are achievable with blade systems. [2]
In 2015 the DS6000 line were discontinued, and the all-flash entry-level DS8882F model was released as a rack-mount successor of DS6000 line. All IBM DS storage lines are based on an IBM Power CPU and use IBM Power Systems servers as controllers.
The choice of racks in a server room is usually the prime factor when determining space. Many organisations use telco racks or enclosed cabinets to make the most of the space they have. Today, with servers that are one-rack-unit (1U) high and new blade servers, a single 19- or 23-inch rack can accommodate anywhere from 42 to hundreds of servers.
On the 720 line, Dell currently offers two rack-model servers: the Poweredge R720 [125] and the R720XD [126] — where the latter offers the option to extend the system to up to 26 internal disks. The Poweredge 620 series offer models for rack, tower and a ½ height blade-server M620. [124]
