Large-scale computer systems have been around for a while, and many people are already familiar with the term data center. In the 1940s, computers were so large that individual rooms had to be specially set aside to house them. Even the steady miniaturization of the computer did not initially change this arrangement because the functional scope increased to such an extent that the systems still required the same amount of space. Even today, with individual PCs being much more powerful than any mainframe system from those days, every large-scale operation has complex IT infrastructures with a substantial amount of hardware – and they are still housed in properly outfitted rooms. Depending on their size, these are referred to as “server rooms” or “data centers.”
In addition to these “hard” factors, one must also take into consideration organizational measures, such as periodic backups that ensure operability. As a rule, the more extensive and critical the hardware and software become, the more time and effort are required to provide optimal protection.
For that reason, a data center preferably consists of a well-constructed, sturdy building that houses servers, storage devices, cables, and a connection to the Internet. In addition, the center also has a large amount of equipment associated with supplying power and cooling, and often automatic fire extinguishing systems.
