服务器整合已成为一种有前景的技术，可降低数据中心的能源成本。在这项工作中，我们从寻找整合特征的角度对企业服务器工作负载进行了首次详细分析。我们发现，如果根据应用需求的非高峰值进行整合，节能潜力巨大。然而，由于整合会带来相关风险，特别是在不考虑应用之间的相关性时。我们还研究了低风险整合的利用率趋势的稳定性。利用工作负载分析得出的见解，设计了两种新的整合方法，在实现显著节能的同时，控制了整合的性能风险。我们介绍了在一个整合规划工具中这些方法的实现，并对所提出的方法进行了全面的评估研究。
Server consolidation has emerged as a promising technique to reduce the energy costs of a data center. In this work, we present the first detailed analysis of an enterprise server workload from the perspective of finding characteristics for consolidation. We observe significant potential for power savings if consolidation is performed using off-peak values for application demand. However, these savings come up with associated risks due to consolidation, particularly when the correlation between applications is not considered. We also investigate the stability in utilization trends for low-risk consolidation. Using the insights from the workload analysis, two new consolidation methods are designed that achieve significant power savings, while containing the performance risk of consolidation. We present an implementation of the methodologies in a consolidation planning tool and provide a comprehensive evaluation study of the proposed methodologies.
