Introduced in this paper, in accordance with ANSI/TIA/EIA - 606 - A summary of the data center placed cabinet, frame selection skills...
In data center, racks and racks of placement and distribution location according to the points of overhead floor to decorate, and marked in accordance with ANSI/TIA/EIA - 606 - A, must be used in the data room two letters and Arabic numerals to tag each piece of 600 mm? 600 mm raised floor.
The cabinet/rack is put at the front, back and height of the column, ANSI/TIA/EIA for the following provisions:
1. The cabinet/rack column spacing on the back of the smallest need interval of 0.6 m (2 feet), the recommended interval of 1 meter (3 feet);
2. The front of the cabinet/rack column minimum interval is 1 meter (3 feet), if there is a deeper equipment placed in the rack/cabinet, recommended interval 1.2 meters (4 feet);
3. Cabinet/rack maximum allowable height is 2.4 meters (8 feet), the recommended maximum height of 2.1 metres (7 ft).
It is recommended to use standard 19 inch wide cabinet/rack, also can choose 23 inches wide cabinet/rack. When using multiple cabinets connected into a rack column, must be between the cabinet, and the entire cabinet of column between vertical cable manager and end use. Rack and the width of the vertical cable manager of cabinet shall not be less than 25.4 centimeters (10 inches), and in between and at the end of the width of the vertical cable manager shall not be less than 15.25 cm (6 inches), so that cable in the cabinet and runs through the protection and management of cable cabinet.
For data center, the optimal running environment is 22 ~ 24 degrees, relative humidity between 35% ~ 35%, therefore, air conditioning refrigeration system can meet the above requirements. Any changes or changes in relative humidity temperature will result in sensitive equipment can't normal work, any dramatic changes in temperature or humidity change may cause the damage of equipment.
With increasing the amount of communication machine room equipment and the application of new technology, superior performance of the refrigeration system is more important than ever. For example, a high density of the blade server will cause they near heat is rapidly increasing, therefore, request the refrigeration can be realized in these places, in order to make the blade server work in the optimization of the environment.
Now manufacturers to provide equipment calorific value has been more and more prevalent, the typical calorific value represented by watt or BTU/h. Usually have different selection of refrigerating system, from air auxiliary cooling system (fan) to the standard of the air conditioning system and forced heat removal system, etc. In usually installed equipment rack/cabinet, cold air entrance is in front of the cabinet/rack, the hot air from the back. Therefore, TIA/EIA - 942 standard advice to arrange equipment row alternation mode, namely the cabinet/rack is arranged to form a face to face hot and cold area. Cooling zone is in the front of the rack/cabinet area, if there are anti-static floor, power cable distribution best under the floor, and through the opening of anti-static floor from the previous cabinet cold area.
Hot spots located in the back of the rack/cabinet, contains telecommunication wiring slot. Above the device, to adopt to the cooling configuration before. In view of the cable layout, electronic equipment in the cooling channels on both sides of the relative arrangement, air conditioning blow out from the borehole overhead floor. Channels on both sides of the electronic equipment is back to back, hot channel under the floor without hole, ceiling fan, the heat data cable laying under the floor.
For better use of the existing refrigeration, exhaust system, the data center design and construction, should avoid the circuitous air, cause the hot air is not directly eliminate computer room; Avoid overhead floor space under the cable clutter, pile up, blocking the flow of air; Avoid cabinet internal cable pile up too much, influence of hot air emissions; Blank in no load cabinet, recommended baffle to prevent "hot spots" air "cold area", circuitous air flow.
