Green Data Centers: A Survey, Perspectives, and Future Directions [article]

Xibo Jin, Fa Zhang, Athanasios V. Vasilakos, Zhiyong Liu
2016 arXiv   pre-print
In this paper, we provide a survey of the state-of-the-art research on green data center techniques, including energy efficiency, resource management, thermal control and green metrics.  ...  However, because of the over-provisioning of resources, the utilization of existing data centers is, in fact, remarkably low, leading to considerable energy waste.  ...  However, the challenge is to develop CRAC fan speed controllers that can supply a data center with only the necessary cooling demands.  ...

Towards a Systematic Survey for Carbon Neutral Data Centers [article]

Zhiwei Cao, Xin Zhou, Han Hu, Zhi Wang, Yonggang Wen
2022 arXiv   pre-print
Data centers are carbon-intensive enterprises due to their massive energy consumption, and it is estimated that data center industry will account for 8\% of global carbon emissions by 2030.  ...  Following that, carbon neutrality plans for major global cloud providers are discussed to summarize current industrial efforts in this direction.  ...  In [158] , Wang et al. investigated optimal fan speed control for a blade server.
