摘要

本文讨论了用于全42U机架服务器的混合液空冷却解决方案的数据中心规模性能特征。利用在劳伦斯伯克利实验室的生产数据中心收集的数据，我们用一个简单的三参数模型来解释结果，该模型可以描述影响系统热回收效率的主要因素。该模型与各种温度和工作负荷条件下的广泛数据一致。据我们所知，这是混合冷却解决方案在数据中心运行方面的第一次大规模性能表征。我们讨论了如何将这种方法扩展到其他系统，以便对解的性能进行有意义的比较。

Thermal performance modeling of hybrid liquid-air cooled servers

This paper discusses data center scale performance characterization of hybrid liquid-air cooling solutions for a full 42U rack of servers. Using data collected in a production data center at Lawrence Berkeley Laboratories, we interpret the results with a simple three parameter model which allows characterization of the major factors affecting heat recovery efficiency of the system. The model is shown to agree with a broad set of data under a variety of temperature and workload conditions. To our knowledge, this is the first large scale characterization of a hybrid cooling solution's performance in terms relevant to data center operation. We discuss how this method can be extended to other systems for meaningful comparison of solution performance.
