在数据中心建设中，似乎总会面临「To be, or not to be」迷局。谁都知道，在数据中心偶面积方面基本是寸土寸金，想有效的利用空间面积，采用高密度机柜布局似乎是一个不错的选择， 可以总是会有专家出来告诉你一组“可怕的数据”: 最新的刀片式服务器机架功率15kW，台式服务器机架功率1.5kW，模块式服务器机架功率5kW。高耗电必然产生局部高温，它使温度梯度变化变大，通风降温变成一个不可能完成的任务。
Density and low density cabinet sheet metal processing technology is very different, we use simple and clear data and chart to show the different features of sheet metal processing, to facilitate the reference of colleagues.
In the construction of data center, it seems that To be or not to be always faces the puzzle. Everyone knows that the area of the data center is basically an inch of gold. To use the space area effectively, the high density cabinet layout seems to be a good choice. There will always be an expert to tell you a group of "terrible data": the latest blade service rack power 15kW, the desktop server rack. Power 1.5kW, modular server rack power 5kW. High power consumption inevitably generates local high temperature, which makes the temperature gradient change larger and ventilation cooling becomes an impossible task.
Advantages of high density cabinet
However, the advantages of high-density rack are obvious, at least it can get higher computing power and availability. Another challenge comes from safety costs (e.g. smoke alarm / square feet), but it does not cause high density to produce a clear fee. In addition, the high level monitoring of higher density will offset these disadvantages.
Will the low density cabinet be sure to save the cost?
In low density space, the cost of lighting is greater. In the space greater than 18000 square feet, 1.6 kW / sq ft of lighting is needed. Increased maintenance costs to some extent also led to an increase in costs.
Comparison between high density cabinet and low density cabinet
IT equipment occupies a large part of the total budget. The following figure lists the cost comparison between high density cabinet and low density cabinet in CFD design cost, lighting cost, IT equipment (cabinet), cooling cost, and total cost of ownership.
Cloud cube pays great attention to air flow in the box. In order to get better control of airflow distribution. "Valuable" cold air must be transported to continue to cool down. At the same time, in order to deal with higher heat load density, the capacity of the cloud cube can change with the change of IT load, which not only improves the efficiency of refrigeration, but also saves energy effectively. Effective reduction of TCO (total cost of ownership)
This shows that high density container data center costs less. In the above example, a total savings of 5200000 dollars or a year's electricity cost are saved.
