What is “Rack-mount“, this is a subject that relates to communication cabinets, those huge rooms with lots of computers. Those computers are being placed in those cabinets, and since we would like to load a maximum number of computers per space, there are Rack-mount computers, exactly for that purpose.
These computers are formed in very thin form, which is sized as U’s, 1U, 2U, 5U etc… The U stands for a number of slots the computer occupies, 1U for 1 slot. A slot is the drawer the computer slides into. What you do is connect to the sizes of the computer tracks which locks into the cabinet’s tracks, so you can slide the computer forward toward you, in case you need to maintain it, and slide it back into place to place it back to its permanent position.
Those U computers (Rack Unit) are usually much more expensive, mostly because of their ability to fit into a communication cabinet, and because their technology is different from the regular standing computers we know of, those who we placed at home, or near our office station. They are built in such way that enables all of the parts to fit into a smaller space, in order for them to fit into those communication cabinet drawers.
Another big benefit for Rack-mount computers is that those are huge computers, which can contain many hard-disk drivers, many CPUs, they are huge processing machines and for the businesses who needs a lot of processing power, these are the computers you need. That is why such computers are being placed in computer rooms, at communication cabinets in hosting places that have huge cooled controlled rooms, with UPSs units that can keep these type of very important servers online at all times.
The most cost effective computer servers to place in a hosting place, are the 1U units, since they catch little place at the hosting farm, and if you need a well kept server at high availability, a hosting farm is what you need.
