ما هي الأحجام القياسية لأرفف الخادم?

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 بوصة) and height (multiple of 4.445cm) of the server. Because the width is 19 بوصة, the rack that meets this requirement is sometimes called “19-رف بوصة”. Thickness is 4.445cm, and 1U is 4.445cm ..

I. Size of 19-inch standard cabinet:
The equipment installation height in the 19-بوصة standard cabinet is expressed by a special unit “ش”, مع 1U = 44.45mm U يشير إلى مساحة الاستخدام الفعالة داخل الخزانة, وعادة ما يتم تصنيع لوحات المعدات القياسية التي تستخدم خزانات قياسية مقاس 19 بوصة وفقًا لمواصفات n u. لبعض المعدات غير القياسية, يمكن تثبيت معظمها وتثبيتها في هيكل مقاس 19 بوصة من خلال حواجز محول إضافية. عرض اللوحة لمعظم معدات الدرجة الهندسية هو 19 بوصة, ومسافة ثقب التثبيت 465 مم. وبالتالي, طالما أن الخزانة يمكنها تلبية متطلبات التثبيت لمعظم المعدات مقاس 19 بوصة, الخزانة عبارة عن خزانة قياسية.

The 19-inch standard cabinet has three general indexes: width, height and depth. The physical width of the cabinet is usually 600mm and 800 مم. عموما, 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. عموما, the depth of the cabinet ranges from 600mm to 1000 مم, 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 مم, 700مم, 800mm and 900 مم. The structure of 19 “standard cabinet is relatively simple, mainly including basic frame, internal support system, wiring system and ventilation system. 2. ال “يو” و “19-بوصة” 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 بوصة) and height (multiple of 4.445cm) of the server. Because the width is 19 بوصة, the rack that meets this requirement is sometimes called “19-رف بوصة”. 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, هذا هو, the cabinet where the 19-inch rack-mounted server can be placed. The cabinet is also divided into U degrees and depth; عموما, 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. عموما, the height ranges from 0.7M-2.4M, and the heights of common finished 19-inch cabinets are 1.6M and 2M. عموما, 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, 600مم, 800مم, 900mm and 1000mm. يتم التعبير عن ارتفاع تركيب المعدات في الخزانة القياسية مقاس 19 بوصة بوحدة خاصة “ش”, with 1U=44.45mm Equipment panels using 19-inch standard cabinets are generally manufactured according to nU specifications. لبعض المعدات غير القياسية, يمكن تثبيت معظمها وتثبيتها في هيكل مقاس 19 بوصة من خلال حواجز محول إضافية. The panel width of many engineering equipment is 19 بوصة, 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 بوصة, 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. وبالتالي, there is no 1U cabinet, only 1U equipment, and there are 4U–47U cabinets, هذا هو, 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.
