          解惑答疑:機箱機柜安裝的10個(gè)問(wèn)題

          發(fā)布時(shí)間:2023-03-16 來(lái)源:http://www.lfnanning.cn/ 瀏覽量:

          1、隱藏的泄漏:冷空氣從活動(dòng)地板下的空間中泄漏出來(lái),進(jìn)入到相鄰的空間或支撐柱中。這種泄露相當的普遍,并導致了冷通道機房環(huán)境中的壓力損失,從而使得別處滿(mǎn)是灰塵的熱空氣或潮濕的空氣進(jìn)入進(jìn)來(lái)。避免這個(gè)問(wèn)題的方法便是去活動(dòng)地板底下檢查周邊和支撐柱,并封住你發(fā)現的任何漏洞。
          1. Hidden leakage: cold air leaks from the space under the raised floor and enters the adjacent space or support column. This kind of leakage is quite common and leads to the pressure loss in the cold channel machine room environment, which makes the hot air or wet air filled with dust enter elsewhere. The way to avoid this problem is to check the surrounding and supporting columns under the raised floor and seal any holes you find.
          2、太多的開(kāi)孔地板:在熱通道和空白區域放置開(kāi)孔地板是毫無(wú)理由的。這樣會(huì )浪費冷卻能力。還有可能是在機架的進(jìn)氣口放置了太多的開(kāi)孔地板。IT機架頂部的溫度低于正常溫度便是一大危險信號。
          2. Too many perforated floors: There is no reason to place perforated floors in hot channels and empty areas. This will waste cooling capacity. It is also possible that too many perforated floors are placed at the air inlet of the rack. The temperature at the top of the IT rack is lower than the normal temperature, which is a big danger signal.
          3、未密封的活動(dòng)地板開(kāi)口:盡管許多冷通道數據中心運營(yíng)商已經(jīng)努力密封了電纜開(kāi)口及活動(dòng)地板中的其他漏洞,但很少人完成了這項工作。剩下的漏洞會(huì )導致大量的冷空氣逸入不被需要的區域。配電單元或遠程電源板等電氣設備是尋找未密封開(kāi)口的一個(gè)特別重要的地方。
          3. Unsealed raised floor openings: Although many cold channel data center operators have tried to seal cable openings and other holes in the raised floor, few people have completed this work. The remaining holes will cause a large amount of cold air to escape into the unwanted area. Electrical equipment such as power distribution unit or remote power panel is a particularly important place to find unsealed openings.
          4、機架密封性不好:把備用面板放置在空的機柜區域是氣流管理的常識,然而并不是每個(gè)人都會(huì )這樣做。一些機柜沒(méi)有被設計好,安裝鋼軌與機柜邊緣之間被封死。關(guān)心效率的經(jīng)營(yíng)者會(huì )密封那些開(kāi)口以及機柜底端的潛在開(kāi)口。
          4. The sealing of the rack is not good: it is common sense to place the spare panel in the empty cabinet area, but not everyone will do so. Some cabinets are not well designed, and the installation rail and the cabinet edge are sealed. Operators concerned with efficiency will seal those openings and potential openings at the bottom of the cabinet.
          5、溫度和濕度傳感器刻度不準:有時(shí)供應商使用了未校準的傳感器,有時(shí)刻度會(huì )隨著(zhù)時(shí)間的推移而變得不準確。這將導致管理不善的冷卻單元不能協(xié)同地工作。建議運營(yíng)商每六個(gè)月校準一次溫度和相對濕度傳感器,并且在必要的時(shí)候進(jìn)行相應的調整。
          5. Inaccurate scale of temperature and humidity sensor: sometimes the supplier uses an uncalibrated sensor, and sometimes the scale will become inaccurate over time. This will cause poorly managed cooling units to not work together. It is recommended that the operator calibrate the temperature and relative humidity sensors every six months and make corresponding adjustments when necessary.
          6、讓CRAC互相牽制來(lái)控制濕度:使兩個(gè)CRAC互相牽制的另一個(gè)好方法是給相鄰的CRAC供以不同溫度的循環(huán)空氣。因此,CRAC有不同的濕度讀數,一個(gè)結束加濕,而另一個(gè)正在干燥空氣。解決這個(gè)問(wèn)題需要巧妙地理解濕度圖,并準確的設置濕度控制點(diǎn)。
          6. Let the CRACs control each other to control humidity: Another good way to make two CRACs control each other is to supply different temperature circulating air to the adjacent CRACs. Therefore, CRAC has different humidity readings, one end humidification, and the other is drying the air. To solve this problem, we need to skillfully understand the humidity chart and accurately set the humidity control point.

          7、物以稀為貴:許多的冷通道數據中心運營(yíng)商預置了過(guò)度的冷卻能力。如果擁有的冷卻能力大于所需,并無(wú)法過(guò)剩的CRACs的,那么整個(gè)的冷卻方案都會(huì )被連累,因為太多的單元處于低效率狀態(tài)。地板下的冷卻溫度很高,且某些機架很難被冷卻時(shí),運營(yíng)商一貫的反應便是運行更多的冷卻單元。然而與直覺(jué)相反,正確的做法應該是運行更少的CRACs來(lái)降低負荷。
          7. Thinning is precious: many cold channel data center operators preset excessive cooling capacity. If the cooling capacity is greater than required and the safety of the excess CRACs cannot be guaranteed, the whole cooling scheme will be affected because too many units are in an inefficient state. When the cooling temperature under the floor is very high and some racks are difficult to be cooled, the operator's consistent response is to run more cooling units. However, contrary to intuition, the correct approach should be to run fewer CRACs to reduce the load.
          8、閑置的濟南機箱機柜空間:這是另一個(gè)明顯的因素,但出于某種原因沒(méi)有被每個(gè)人所重視。當一個(gè)或者多個(gè)機柜空間被空置,將會(huì )破壞氣流平衡,導致廢氣循環(huán)進(jìn)入冷通道,或是在冷通道損失冷空氣。這種情況將導致過(guò)度冷卻,及供應多于實(shí)際所需的空氣來(lái)彌補損失。
          8. Idle Jinan chassis and cabinet space: This is another obvious factor, but for some reason it is not taken seriously by everyone. When one or more cabinet spaces are empty, the air flow balance will be damaged, resulting in exhaust gas circulation into the cold channel, or cold air loss in the cold channel. This situation will lead to excessive cooling and supply more air than is actually required to compensate for the loss.
          9、糟糕的機架布局:理想情況下,你想把機架按加熱/制冷分別排成一行,并把主要的CRACs放置在每行的兩端。擁有一小塊機架且沒(méi)有特定的方向并不能幫助任何人。無(wú)論是從前往后排列機架,還是使CRACs與IT行的方向相同,都無(wú)濟于事。
          9. Bad rack layout: ideally, you want to arrange the rack in a row according to heating/cooling, and place the main CRACs at both ends of each row. Having a small rack without a specific direction can't help anyone. It doesn't help to arrange the rack from front to back, or make the direction of CRACs and IT lines the same.
          10、冷卻管理沒(méi)有受到應有的重視:沒(méi)有想到改進(jìn)冷卻管理方式的好處,使得運營(yíng)商的容量擱淺并花費了更高的運營(yíng)成本。做一些如安裝備用面板等簡(jiǎn)單的工作就可以從中獲益,但它們常常被忽視。
          10. Cooling management has not received due attention: the benefits of improving cooling management methods have not been considered, resulting in the stranding of operators' capacity and higher operating costs. You can benefit from doing some simple work, such as installing a spare panel, but they are often ignored.
