冷却功率通常表示为数据中心总能耗的单一征税成本。有些人估计高达总能源需求的50%。然而，在存在大量冷却选项和优化的情况下，这种观点是相当简单的。为了应对不断上涨的能源成本，该行业引入了集装箱形式的模块化设计，作为数据中心的新构建块。然而，目前还不清楚它们与高架地板数据中心相比的效率如何，以及在什么条件下它们是首选。在本文中，我们提供了比较和定量分析的冷却功率在基于集装箱和高架地板的数据中心。我们的研究结果表明，与高架地板数据中心相比，集装箱在冷却和设施功率方面分别节省了80%和42%，并且当工作负载整合到最少数量的集装箱上时，可以节省41%的冷却功率。我们还表明，冷却优化是不是很有效，在高利用率;和一个高架地板数据中心可以接近集装箱的效率在低利用率时，采用简单的冷却优化。
Cooling power is often represented as a single taxed cost on the total energy consumption of the data center. Some estimates go as far as 50% of the total energy demand. However, this view is rather simplistic in the presence of a multitude of cooling options and optimizations. In response to the rising cost of energy, the industry introduced modular design in the form of containers to serve as the new building block for data centers. However, it is still unclear how efficient they are compared to raised-floor data centers and under what conditions they are preferred. In this paper, we provide comparative and quantitative analysis of cooling power in both container-based and raised-floor data centers. Our results show that a container achieves 80% and 42% savings in cooling and facility powers respectively compared to a raised-floor data center and that savings of 41% in cooling power are possible when workloads are consolidated onto the least number of containers. We also show that cooling optimizations are not very effective at high utilizations; and that a raised-floor data center can approach the efficiency of a container at low utilizations when employing a simple cooling optimization.
