A rack server is a computer designed to be incorporated into a central framework known as a rack. The rack itself contains several bays, mounting slots that are designed to securely hold the hardware unit in place.
The Differences in Physicality
Though similar to a tower in terms of functionality, a rack server is quite different from a construction aspect. The tower is in more of a stand-alone, cabinet like form and typically taller. A rack server offers a low-profile enclosure, which can usually be found on at least two sides of the rack. Businesses of all sizes make use of racks, particularly when they have a need to enable remote access to a private network.
One of the greatest benefits of a rack server is that multiple units can be inserted into the bays of the rack, thus making it much easier to connect them to other network components. This type of setup not only makes it possible to maintain a primary unit, but also a secondary server that is capable of driving the network if an emergency should occur.
Relatively small in design, rack servers generally take up less floor space than towers. Thus, even if you have to transform your small room or utility closet into a server room, the utilization of the correct rack will allow you to make the most of that space with ease. As long as you have a way to keep the area cool and properly ventilated, your rack server can function seamlessly with nothing more than regular maintenance and care.
