Data Center – Some Equipment And Terms Used In Data Centers

Rack

A rack is a rack designed to house electronic equipment, computer and communications systems. The width measures are standardized to be compatible with equipment from any manufacturer, with the extent of 19 more normalized. They are also called racks, cabinets or closets. The racks are a simple metal frame with a standard internal width of 19 inches while the height and depth are variable to suit different needs. The 19-inch racks are used extensively in the fields of telecommunications, computing, audio and video.

The term rack is borrowed from the English name for a holding device, which typically combines a number of smaller elements into a single unit – such as a rack or a rack. Externally, rack mount servers have a standard width of 600 mm and a depth of 800 to 1000 mm. The width of 600 mm for racks of servers matches the standard size of the tiles in the data center. Thus it is very easy to make distributions of space in data centers (also called CPD). Server racks are also used 800 mm wide, when you must have enough lateral space for wiring. These racks have the disadvantage poorer energy efficiency in refrigeration.

The frame has horizontal tracks which can support the team, as well as anchors for the screws that secure the equipment to the frame. In this sense, a rack is very similar to a simple shelf. The racks are very useful in a data processing center, where space is tight and you need to host a large number of devices. These devices are usually:

Servers whose case has been designed to fit the frame: Servers are 1U, 2U, 4U, and recently have become popular compact blade servers allow more sharing power supplies and cabling. The equipment simply slides on a horizontal rail and fixed with screws. There are also trays that can support non-standard equipment, for example, a monitor and keyboard.

19-inch racks

In the event, laboratory and control technology, the term rack (English 19-inch rack) for a rack for electrical equipment with a standard width of 19 inches, in which the individual devices that can be mounted in the rack, a front plate width of exactly 48.26 cm have (eg shelf). One height unit (U, otherwise known rack unit (U)) is specified at 1.75 inch (4.445 centimeters). 19 “Racks are standardized (EIA 310-D, IEC 60297 and DIN 41494 SC48D), whereby the installation of any device is possible as long as they also meet the said standards.

Racks — for use in Information Technology

Standard racks for data centers are about 2 feet high and usually offer a net volume of 42 HU. They are available in depths of 60 cm, 80, 100 or 120 cm and widths of 60, 70 or 80 cm. The larger widths provide additional lateral space for the wiring. The racks can be closed to cabinets with side panels and doors.

Sound Technology

Also in audio engineering, the use of equipment has been set, mounted in racks. They are used primarily in the area of the PA and studio equipment, including equalizer, amplifiers, effects and dynamics processors. Racks for stage technology are designed as a flight case.

Furniture

The term rack is also used for shelving for storage and presentation of audio and TV sets. This hi-fi racks or TV racks have no standard widths and are usually adapted to the size of the optics and stereo systems. To produce these racks mostly materials such as stainless steel, glass or aluminum are used.

Drum Racks

As a rack called a frame on which the individual parts of a drum kit are fixed, ie mainly Tom toms and, occasionally, other instruments such as percussion instruments and effects.

Traditionally, one needed to build a drum kit a variety of stands: At most one or at most two tom toms can be mounted on the bass drum, otherwise, each pool and each drum (except bass drum) mounted on its own stand, the Tom Tom, however, often in pairs (two on a stand) or permanently attached legs (floor toms). This structure has the consequence that the drummer is surrounded by a maze of stands. Since virtually every stand has three feet, is often even the place in short supply, especially if microphones are also placed.

As an alternative to this conventional structure, the rack offers only a few legs (two to four) to suspend the possibility of a myriad of instruments. For this purpose, the legs are connected with horizontal cross bars on which holders for cymbals, drums and other instruments are bolted. This has been established as a standard has the rack to the electronic drums.

More Racks

  • The International Standard Payload Rack is the mounting base for research modules of the International Space Station (ISS).
  • The mini rack or 10 inch rack is a smaller version of the 19-inch rack, which is usually less deep. Use, it refers primarily in the private sector and in smaller installations. Some particularly small units in the 19-inch screen are known as mini-racks. Many tavern suitable for wall mounting.

Router

The router switch or router is a hardware device for interconnection of computer network that operates at layer three (network layer) of the OSI model. A router is a device for computer networking that ensures packet routing between networks and determines the best path to take the data packet. Routers may provide connectivity inside enterprises, between enterprises and the Internet and within the Internet service providers (ISP).

The routers are often used in homes to connect to a broadband service such as IP over cable or DSL. A router used in a home can allow connectivity to an enterprise through a secure virtual private network. While functionally similar to routers, residential routers use network address translation instead of routing. Instead of connecting local computers to the network directly, a residential router must make local computers appear to be a single computer.

Access Routers

Access routers, including SOHO, are located at customer sites and locations that do not need hierarchical routing of their own. Normally, they are optimized for low cost.
