Have you ever been tasked to find memory for server? Well, if you do you know how frustrating it can be, especially with all the different terminology.

If you are looking for server space, you get a mixture of conflicting information, the shelves 19a are called?? Rack-Racks is the width and depth in millimeters and the assembly posta? s are in UA? s.

A 19-inch rack is a standardized system for mounting various electronic devices in a rack 19A? wide, the rack takea? s itsa? Names of the dimensions between the mounting rails at the front and back of the rack.

The racks are taken at different depths: 600 mm deep, 800 mm deep, deep 1000 mm and different widths: 600 mm wide and 800 mm wide. This completely depends on what equipment is stored on the shelves.

The internal storage heights called? UA? SA ????, This is a measurement that corresponds to 44. 45 mm or 1 75a ????, for example, a server rack mount comes in 1U, 2U 4U accommodate, for example, a 42U rack 10 theoretically is x 4U server. But you need to allow for air flow, because you do not want the Cabinet of heat, so that every room uses a 4U space of 1U is empty, it can be closed with dummy plates â?? This is the industry standard. Some say the letter U as a standard for the word unit is used. The standard of the rack were set up by the Electronic Industries Alliance, and is known as EIA-310-D.

If we call the server and 1U themselves, they are not exactly first 75 inch (1U), they are 1 / 32 inch smaller (usually first 719 instead of 1 cm. 75 inches) and this is a small tolerance allowed within the cabinet, so that the equipment is not in the other devices Rack to catch.

Where these racks are used? They are used in telecommunications applications for the storage of all data networks and telephone systems, ISPA?? S for all sites host the audio industry to accommodate the recording and save the railways relay.

A Racka? S mounting rails and mounting hardware hot run vertically from top to bottom in the rack rails each 5/8â? with a wide gap between them of 17 years. 75 inches, which the entire internal rack size of 19 inches.

Mount the devices to the mounting rails, a few shelves are pre-hole, knocked on the screw that is supplied with the server drilled last are, others have racks cage nuts are the nuts that help captive steel wrap that fits in comfortably, the square holes in the rails.

should be installed when a piece of electronic equipment for example, that 450mm depth 600mm depth in a rack have been saved, (this depth would be dictated by the lowest equipment will be on it), that’s hard, you would mount rails, this flight against the front rails, the rear rails in the rack and distribute the load evenly.

Cooling is important if you plan to fill a rack of its capacity, there are several ways to cool a rack. First, if you are just storing server, you need from front to back cooling, this is achieved in data centers with air-conditioned rooms and ventilated front and rear doors, these doors have either fine slots or holes in them are drawn for the air in the cabinet and cool each server.

The second possibility is to have air blown into the shelves out of nowhere into the ground, exhausted from the room, which is more expensive.

The last option is a fan or air conditioning unit installed in the roof were cut, these come in various configurations to suit the application.

Some companies like Bay together (- this is achieved with a baying kit consists of 4 long screws) 2 shelves, saving one of the active equipment (servers) and a retention of passive devices (hubs, routers, etc) if this is the case Racks bonded to earth, so if there is a short circuit, no one gets an electric shock.
