What are Rack Servers | Characteristics | Features

There are several types of rugged computers out there supporting a variety of different military, industrial and commercial applications. The most common, however, is the unmistakable rack server. You can buy refurbished rack servers in Nigeria without spending too much money compared to a new one.

These slidable, hot-swappable, high-powered rugged computers are ideal for harsh environments and programs that emphasize space conservation, scalability, upgradability and expandability.

In this blog post, we’ll discuss how a rack server works, the different sizes of rack servers and server racks, and how you can choose the best of both to fit your program or application.

What is a rack server?

A rack server, also known as a rack mount server, rack-mounted server or rack mount computer, is a computer designed to be situated in a rectangular structure called a server rack.

The advantages of a server rack include better space conservation for rack servers, increased scalability, maximized air flow when coupled with a cooling system and ease of regular computer maintenance and diagnostics, given that their design allows technicians and operators to easily slide rack servers in and out of them.

What is a rack server used for?

Like all servers, rack servers provide data and specific services to clients. They’re commonly found in data centers full of dozens, or even hundreds, of server racks and server rack cabinets.

Rugged rack servers are often found in the field supporting military and industrial applications.

Certified to military and industrial standards such as MIL-STD-810H, MIL-STD-461, CE, FCC or DO-160, these reliable, high-powered machines are stress-tested to withstand harsh environmental conditions, such as extremely high or low temperatures, vibration during transport or operation and humidity in parts of the world where atmospheric moisture is pervasive.

In military programs, rack servers can often be found situated inside compact and sturdy MIL-STD-810-certified rack server cases or supporting an embedded computing application.

How does a rack server work?

Mechanically, rack servers are able to slide in and out of a server rack with ease. This feature comes in handy, allowing systems administrators, technicians and operators to diagnose technical problems and hot-swap parts without shutting down and disassembling the entire system. Such a feature is vital to mission-critical programs and applications, in which lengthy periods of downtime could result in financial loss, injury or even death.

Computationally, a rack server’s performance, resources and services are specific to the needs of a program or application.

A remote military installation in the desert may need a high-powered rack database, email, web, file or application server to support on-site computation and access to critical resources and intelligence, while a commercial warehouse or industrial oil rig may operate a series of rack servers that store and process data from security cameras, assembly line computers or fracking control systems.

How wide is a rack server?

Most rack servers are 19 inches in width and thus can fit the standard 19-inch server rack configuration. Industry server racks typically come in the 19-inch configuration but are also offered at 23 inches and 24 inches in width.

The height of both server racks and rack servers is usually measured in rack units. One rack unit (U) is equal to 1.75 inches.

Server racking is the process of determining how many rack mount servers a server rack can hold.

When shopping for rack mount computers, you’ll often see the rack unit measurement expressed as [number]U.

To determine the height of your server or rack in inches, simply multiply the rack unit number by 1.75 inches.
