Rack servers are computers that are designed to function as servers and are configured for installation in a central framework that is known as a rack. Sometimes referred to as a rack-mounted server, this computer fits neatly into a slot in the rack and functions to coordinate all local and remote sharing that is conducted throughout the facility. Both small large businesses make use of rack-mounted servers, especially if there is a need to provide remote access to a private network.
While similar to a tower server in function, these two types of servers are different is construction. The tower server is more of a cabinet that stands alone, and tends to be taller. The rack server, by contrast, allows access to the servers by opening enclosures found on at least two sides of the rack. It may also take up less space than a tower server, although this is not always the case.
One of the advantages of rack mounting is that several servers can be placed into the bays or slots of the rack. This makes it easy to connect the computers to other network components. Doing so not only makes it possible to maintain a primary server, but to also establish a secondary server that will drive the network in the event of an emergency. With larger companies, a series of servers may service different parts of the network, while allowing the connected servers to exchange data on an as needed basis.
In a basic rack server setup, the server is held in place with the use of simple screws found in the bays of the rack. This safety measure is helpful in making sure that a computer does not slip out of place and land on the floor. Along with securing the servers in place, the open configuration of the rack also provides for the easy flow of cool air from systems that help to keep the servers and other network components at a constant temperature.
Because of its relatively small design, the rack is also designed to take up less floor space. This means that, even if a utility closet has to be turned into the new home for the servers, there are racks that will fit into the space with ease. As long as there is some way to keep the small area cool, the server can function with nothing more than routine maintenance and care.
