Abstract

This work presents the effect of servers and racks heat capacity on common dynamic scenarios in data centers. Room level Computational Fluid Dynamics (CFD) model is developed to simulate airflow rate and servers power fluctuations in a representative data center. It is found that the servers heat capacity has a significant effect on the dynamics of data centers. An order of magnitude increase is observed in the time constant associated with change in temperatures compared with models that neglects the effect of servers heat capacity. It is also found that the rack chassis heat capacity has a slight influence on temperatures rate of change, thus it can be neglected without affecting the accuracy of the results and also reducing the computational time.

在数据中心的基于物理的动态CFD模型中建模机架和服务器的热容量

这项工作展示了服务器和机架热容量对数据中心常见动态场景的影响。建立了机房级计算流体动力学(CFD)模型，用于模拟某代表性数据中心的气流速率和服务器功率波动。研究发现，服务器的热容对数据中心的动态运行有着重要的影响。与忽略服务器热容影响的模型相比，观察到与温度变化相关的时间常数增加了一个数量级。研究还发现，机架机架热容对温度变化率的影响很小，可以忽略，不影响计算结果的准确性，也可以减少计算时间。
