サーバーラックの標準サイズとは?

We often say how many U cabinets are used, so what is the concept of U? The following small series will summarize some problems about cabinet size for you. U is a unit of server external dimensions, which is an abbreviation of unit. The detailed dimensions are determined by the American Electronics Industry Association (EIA), which is an industry group. The reason for specifying the size of the server is to keep the server in an appropriate size so that it can be placed on an iron or aluminum rack. The rack is provided with screw holes for fixing the servers, so that it can be aligned with the screw holes of the servers, and then fixed with screws to facilitate the space needed for installing each server. The specified dimensions are the width (48.26 cm = 19 インチ) and height (multiple of 4.445cm) of the server. Because the width is 19 インチ, the rack that meets this requirement is sometimes called “19-インチラック”. Thickness is 4.445cm, and 1U is 4.445cm ..

I. Size of 19-inch standard cabinet:
The equipment installation height in the 19-インチ standard cabinet is expressed by a special unit “あなた”, with 1U=44.45mm Uはキャビネット内の有効利用スペース, 19 インチの標準キャビネットを使用する標準装備のパネルは、通常、n u の仕様に従って製造されます。. 一部非標準装備の場合, それらのほとんどは、追加のアダプター バッフルを介して 19 インチのシャーシに取り付けて固定できます。. ほとんどのエンジニアリンググレードの機器のパネル幅は 19 インチ, とインストール穴の距離は 465 んん. したがって, キャビネットがほとんどの 19 インチ機器の設置要件を満たすことができる限り, キャビネットは標準的なキャビネットです.

The 19-inch standard cabinet has three general indexes: width, height and depth. The physical width of the cabinet is usually 600mm and 800 んん. 一般的に, the height is from 0.7M2.4M, which depends on the number of equipment in the cabinet and uniform style. Usually, manufacturers can customize special heights. The common finished 19-inch standard cabinets are 1.6M, 1.8M and 2M in height. 一般的に, the depth of the cabinet ranges from 600mm to 1000 んん, depending on the size of the equipment in the cabinet. Usually, manufacturers can customize products with special depth. The common finished 19-inch standard cabinets have depths of 600 んん, 700んん, 800mm and 900 んん. The structure of 19 “standard cabinet is relatively simple, mainly including basic frame, internal support system, wiring system and ventilation system. 2. の “U” そして “19-インチ” U of electronic standard cabinet are a unit for expressing the external dimensions of the server, which is an abbreviation of Unit. The detailed dimensions are determined by the American Electronics Industry Association (EIA), which is an industry group. 1U=44.45mm=1.75 inches, 1 inch = 25.4mm 19 = inches, 482.6mm The reason for specifying the size of the server is to keep the server in an appropriate size so that it can be placed on an iron or aluminum rack. The rack is provided with screw holes for fixing the servers, so that it can be aligned with the screw holes of the servers, and then fixed with screws to facilitate the space needed for installing each server. The specified dimensions are the width (48.26 cm = 19 インチ) and height (multiple of 4.445cm) of the server. Because the width is 19 インチ, the rack that meets this requirement is sometimes called “19-インチラック”. The thickness is 4.445cm as the basic unit. 1U is 4.445cm, and 2U is 8.89cm which is twice as large as 1U. The 19-inch standard cabinet 19 represents the width, あれは, the cabinet where the 19-inch rack-mounted server can be placed. The cabinet is also divided into U degrees and depth; 一般的に, the height is 42U, and 1U and 19 inches here are industrial standards formulated by EIA. The structure of standard cabinet is relatively simple, mainly including basic frame, internal support system, wiring system and ventilation system. The 19-inch standard cabinet has three general indexes: width, height and depth. Although the installation width of 19-inch panel equipment is 465.1mm, the physical width of cabinets is 600mm and 800mm. 一般的に, the height ranges from 0.7M-2.4M, and the heights of common finished 19-inch cabinets are 1.6M and 2M. 一般的に, the depth of cabinet ranges from 450mm to 1000mm, depending on the size of equipment in cabinet. Usually, manufacturers can customize products with special depth. The common finished 19-inch cabinets have depths of 450mm, 600んん, 800んん, 900mm and 1000mm. 19インチ標準キャビネットの機器設置高さを特殊単位で表現 “あなた”, with 1U=44.45mm Equipment panels using 19-inch standard cabinets are generally manufactured according to nU specifications. 一部非標準装備の場合, それらのほとんどは、追加のアダプター バッフルを介して 19 インチのシャーシに取り付けて固定できます。. The panel width of many engineering equipment is 19 インチ, so the 19-inch cabinet is the most common standard cabinet. 42U refers to the height, 1U=44.45mm,42u The cabinet of 42u can’t hold 42 1U servers, but it is normal to put 10-20 servers, because they need to radiate heat at intervals of 19 インチ, which is 482.6mm wide (there are “ears” on both sides of the equipment, and the mounting hole distance of the ears is 465mm). The depth of the equipment is different, and the national standard does not specify how much the depth must be, so the depth of the equipment is determined by the equipment manufacturer. したがって, there is no 1U cabinet, only 1U equipment, and there are 4U–47U cabinets, あれは, a 42U cabinet can theoretically install 42 1U high equipment, but in practice it is normal to put 10-20 equipment, because they need to dissipate heat at intervals.
