Rugged processors are available in a variety of configurations to support a wide range of military, industrial, and commercial applications. The unmistakable rack server, on the other hand, is the most prevalent.
These high-powered, slidable, hot-swappable rugged computers are suitable for harsh environments and programs that prioritize room conservation, scalability, upgradeability, and expandability.
We’ll go into how a rack server operates, the various sizes of rack servers and server cabinets, and how to choose the best of both for your software or application in this blog post.
Rack Server Explained
A rack server, also known as a rack-mount server, rack-mounted server, or rack mount computer, is a computer that is built to fit into a rectangular server rack.
Since their construction allows technicians and operators to quickly slide rack servers in and out of them, server racks provide improved room conservation for rack servers, increased scalability, maximized airflow when combined with a cooling system, and ease of routine network servicing and diagnostics.
What is a rack server used for?
Rack servers, like all servers, offer data and resources to customers. They’re usually found in data centers with thousands, if not hundreds, of server racks and cabinets. Rugged rack servers are commonly seen serving military and industrial applications in the region.
These dependable, high-powered devices are stress-tested to endure severe environmental environments such as excessively high or low temperatures, friction during transport or service, and humidity in areas of the world where ambient moisture is ubiquitous, according to military and industrial requirements such as MIL-STD-810H, MIL-STD-461, CE, FCC, or DO-160. Rack servers are often used in military systems, either within MIL-STD-810-certified rack server cases or supporting an embedded computing application.
How does a rack server work?
Rack servers can easily slip in and out of a data rack mechanically. This feature is useful because it helps system managers, mechanics, and operators to diagnose mechanical faults and repair components without having to shut down and disassemble the whole system. Long stretches of downtime could result in financial damage, illness, or even death, so such a function is important for mission-critical programs and applications. The output, resources, and services of a rack server are computer-specific to the needs of a program or application.
A high-powered rack database, email, network, file, or application server may be required by a remote military facility in the desert to enable on-site computing and access to sensitive resources and information, while a commercial warehouse or industrial oil rig may use a set of rack servers to store and process data from surveillance cameras, assembly line computers, or fracking control systems.
How wide is a rack server?
Since most rack servers are 19 inches wide, they can fit in a regular 19-inch server rack. Industry server racks are usually 19 inches wide, but they are often available in 23 and 24-inch widths.
Rack units are used to calculate the height of all data racks and rack servers. 1.75 inches equals one rack unit (U). The method of deciding how many rack mount servers a data rack can accommodate is known as server racking.
When looking for rack mount computers, the rack unit calculation is often represented as [number]U.
Simply add the rack unit number by 1.75 inches to get the height of the server or rack in inches.
A rack server, for example, can have a 1U rack height, which equates to 1.75 inches of vertical space; as a result, a rack must have at least 1U rack dimensions, or at least 1.75 inches of vertical space, in order for the rack server to fit properly.
Consider a 4U rack server, which has a vertical area of 7 inches. A standard small server rack with a 4U rack height can accommodate one 4U rack server, which is a natural match for a 7-inch server, but it can also hold the following:
- Four 1U rack servers, requiring 1.75 inches of vertical space per server
- Two 2U rack servers, requiring 3.5 inches of vertical space per server
- One 3U rack server and one 1U rack server, requiring 5.25 and 1.75 inches of vertical space, respectively
- One 2U rack server and two 1U rack servers, requiring 3.5 inches of vertical space for the 2U server and 1.75 inches of vertical space for each 1U server
Naturally, server racks that are much taller than a 4U rack exist.
The 42U and 44U rack heights, which equate to 73.5 and 77 inches of usable space, respectively, are also common. You could use a variety of different-sized rack servers in these racks, or you could only use twenty-one 2U rack servers in the 42U rack and twenty-two 2U rack servers in the 44U rack.
However, there are racks that are much taller than the 44U. Rack Solutions says that it’s $969 70U Open Frame Data Rack follows all Electronics Industries Alliance (EIA) specifications and is “perhaps the tallest server rack in the world.” Consider the options.
How do I choose a server rack?
The server rack you choose will be determined by the requirements of your company, software, or service.
You’ll need to figure out how many servers you’ll need for your project, as well as the height (RUs) and width (in inches) of your server rack. To pick the right rack-scale, compare these dimensions to the height and width of your servers.
Which rack server is best?
The best rack server for your software or service can be determined by a number of factors, including height, weight, and power (SWaP), as well as scalability, expandability, and upgradeability.
In general, the larger the server, the more expansion and storage opportunities you have. But, when you add more modules, the server becomes heavy and will need more power.
