The effect of heat dissipation in the machine room is closely related to the selection and placement of cabinets

有關機柜很容易被忽略。目前液冷(或稱水冷)機柜是討論多的話題，更準確的描述是采 用液冷門的機柜。高密度服務器部署是數據中心建設發展的必然，由此而引發的散熱問題，理應引起高度的重視。小小一個機柜，蘊含著巨大的玄機。新一代數據中心是當今的熱點，無論是資源整合、虛擬化;還是綠色節能、自動化以及安全管理，都是業界津津樂道的話題。

Relevant cabinets are easily ignored. At present, liquid cooling (or water cooling) cabinet is the most discussed topic, and a more accurate description is the cabinet with liquid cooling door. The deployment of high-density servers is inevitable for the construction and development of data centers. The resulting heat dissipation problem should be paid great attention. A small cabinet contains a huge mystery. The new generation data center is a hot spot today, whether it is resource integration or virtualization; Green energy conservation, automation and safety management are all topics that the industry likes to talk about.

對于差一些的數據中心，其電力配備就只有6.8A，對于刀片服務器而言。一個滿配的刀片服務器，其所需要的電力大約為10A。

For poor data centers, the power allocation is only 6.8a, and for blade servers. A fully equipped blade server requires about 10a of power.

按照數據中心現有的能力計算，10A電力配備顯然無法滿足更多臺刀片服務器部署的需求，電力不足的矛盾非常突出。如何解決供電不足的難題，容易想到的是從擴容入手。實際上，在數據中心或者是樓宇構建之初，對于電力容量就有一定的測算。如今，增加電力容量，這就需要電力部門進行擴容，并涉及到相應的線路、開關等設備的改造，其所牽涉的因素很多，受制約的因素也很多。

According to the existing capacity of the data center, the 10A power configuration obviously can not meet the deployment needs of more blade servers, and the contradiction of power shortage is very prominent. How to solve the problem of insufficient power supply, the easiest thing to think of is to start with capacity expansion. In fact, at the beginning of the construction of the data center or building, there is a certain calculation of the power capacity. Nowadays, increasing the power capacity requires the power sector to expand the capacity, and involves the transformation of corresponding lines, switches and other equipment, which involves many factors and restricted factors.

對于現有用電情況進行合理調整，是應對電力不足的另外一個解決辦法，通過采用一套稱之為"適應性數據高可用管理的方案工具，對現有一些企業的數據中心進行監控，結果發現，10%左右的電力能耗用于燈光照明等，而用于IT設備的電力消耗大約只有30%，其余大量的電力消耗在制冷，也就是說，運營管理的成本已經大大超過了設備的實際使用成本。

Another solution to the power shortage is to reasonably adjust the existing power consumption. By using a set of solution tools called "adaptive data high availability management", we monitor the data centers of some existing enterprises. It is found that about 10% of the power consumption is used for lighting, while only about 30% is used for it equipment, The remaining large amount of power is consumed in refrigeration, that is, the cost of operation and management has greatly exceeded the actual use cost of the equipment.

通過合理的布局，以及科學的熱力模型設計，將可以大大降低運營維護設備的電力消耗，有效緩解電力不足的矛盾，從機柜入手空調制冷成本的居高不下，與機架/機柜以及散熱模型的設計有關。

Through reasonable layout and scientific thermal model design, the power consumption of operation and maintenance equipment can be greatly reduced and the contradiction of power shortage can be effectively alleviated. Starting from the cabinet, the high cost of air conditioning refrigeration is related to the design of rack / cabinet and heat dissipation model.
