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

有關(guān)機(jī)柜很容易被忽略。目前液冷(或稱水冷)機(jī)柜是討論多的話題，更準(zhǔn)確的描述是采 用液冷門(mén)的機(jī)柜。高密度服務(wù)器部署是數(shù)據(jù)中心建設(shè)發(fā)展的必然，由此而引發(fā)的散熱問(wèn)題，理應(yīng)引起高度的重視。小小一個(gè)機(jī)柜，蘊(yùn)含著巨大的玄機(jī)。新一代數(shù)據(jù)中心是當(dāng)今的熱點(diǎn)，無(wú)論是資源整合、虛擬化;還是綠色、自動(dòng)化以及管理，都是業(yè)界津津樂(lè)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(duì)于差一些的數(shù)據(jù)中心，其電力配備就只有6.8A，對(duì)于刀片服務(wù)器而言。一個(gè)滿配的刀片服務(wù)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(shù)據(jù)中心現(xiàn)有的能力計(jì)算，10A電力配備顯然無(wú)法滿足更多臺(tái)刀片服務(wù)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(kuò)容入手。實(shí)際上，在數(shù)據(jù)中心或者是樓宇構(gòu)建之初，對(duì)于電力容量就有一定的測(cè)算。如今，增加電力容量，這就需要電力部門(mén)進(jìn)行擴(kuò)容，并涉及到相應(yīng)的線路、開(kāi)關(guān)等設(shè)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(duì)于現(xiàn)有用電情況進(jìn)行合理調(diào)整，是應(yīng)對(duì)電力不足的另外一個(gè)解決辦法，通過(guò)采用一套稱之為"適應(yīng)性數(shù)據(jù)高可用管理的方案工具，對(duì)現(xiàn)有一些企業(yè)的數(shù)據(jù)中心進(jìn)行監(jiān)控，結(jié)果發(fā)現(xiàn)，10%左右的電力能耗用于燈光照明等，而用于IT設(shè)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(shuō)，運(yùn)營(yíng)管理的成本已經(jīng)大大超過(guò)了設(shè)備的實(shí)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(guò)合理的布局，以及科學(xué)的熱力模型設(shè)計(jì)，將可以大大降低運(yùn)營(yíng)維護(hù)設(shè)備的電力消耗，有效緩解電力不足的矛盾，從機(jī)柜入手空調(diào)制冷成本的居高不下，與機(jī)架/機(jī)柜以及散熱模型的設(shè)計(jì)有關(guān)。

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.
