Understand why a "U" so important for servers and 19 berries?
Have you ever been charged with finding the storage for servers? Well, if you know how frustrating it can be, especially with all the different terminology.
When you're search server storage, you get a mix of conflicting information, the racks are called 19 "rack-mount rack, the width and depth in millimeters and are mounting as U.
A 19 "is a standardized system for mounting various electronic equipment 19" wide, the grid have their "name of the dimension between the mounting rails at the front and rear rack.
The media can come to different depths: 600 mm deep, depth 800 mm, 1000 mm wide, deep and different: 600 mm wide and 800 mm wide. It depends entirely on what equipment is stored in lockers.
The heights of internal storage is called "U" is a measure that equals 44.45 mm or 1.75 by example, a server rack in 1U, 2U 4U, For example, a 42U rack theoretically up to 10 x 4U servers. However, you must allow the flow Air They do not want the cabinet to more heat, so for all space used 4U 1U space is empty, it can be closed shutter plates – Is the industry standard. Some say the letter U is used as a standard for the unity of the word. The rule of the door were created by the Electronic Industries Alliance and is known as EIA-310-D.
When we call 1U servers and I are not exactly 1.75 inches (1U) that are 1 / 32 of an inch smaller (usually 1719 inches instead of 1.75 inches), allowing a small tolerance around the cabinet to the computer does not catch on other equipment in the rack.
Where are these media are used? They are used in applications telecommunications networks to store all data and telephone systems, ISP to host all websites, the audio industry to accommodate the recording equipment to store and track the signal relay.
A door-mounting accessories are called mounting rails and running vertically from top to bottom in the rack, each channel is 5 / 8 inches wide with a separation of 17.75 inches between them giving the size of the inner frame total of 19 inches.
Assemble the rail mounting hardware, brackets are pre-threaded holes to take the screws provided with the server, other media cage nuts, they are nuts to help captive steel hoop that fits in the square hole mounting rails.
If you were to store a piece of electronic equipment, for example, is 450 mm in depth in a depth of 600 mm rack (This depth is dictated by the most profound piece of equipment to be mounted) This is heavy, which is mounted grab bars, they go back on the rails of rack rails and distribute weight evenly.
Refrigeration is essential if you plan to fill a shelf in his ability, there are several ways to cool a rack. First Instead, if you store servers are required cooling on the pole, is done in data centers with air conditioning and ventilating front and rear doors, these doors have grooves or a fine or holes in them so that air is sucked into the cabinet and cool each server.
The second option is to look blown into the baskets from scratch in the soil and the depletion of the room is more expensive.
The last option is to have a fan or air conditioning installed a drive in the ceiling cavity, they come in different configurations to meet demand.
Some companies, like the Bay (Contact – This is accomplished with a kit of juxtaposition and includes 4 screws) 2 materials, storage of active equipment (servers) and a passive storage equipment (hubs, routers, etc.) if that is the case of holders of land to be bonded, so if there is a short that nobody gets electric shock.
