近年来,数据中心大量数据处理和计算的增加导致了严重的能源消耗问题,这也导致了显著的碳足迹和对环境的负面影响。越来越多拥有运营中心的IT公司正在采用可再生能源作为其能源供应的一部分,以抵消棕色能源的消耗。针对混合能源供电的绿色数据中心,利用数据中心工作负载的时间灵活性,提出了一种热感知的工作负载管理方法,同时考虑计算设备和冷却设备的功耗,最大限度地利用可再生能源。我们的方法的关键旋钮是工作负载转移,根据可再生能源供应的可用性和冷却温度的变化,在数据中心调度更多的延迟容忍工作负载和分配资源。为了评估所提出的方法的性能,我们进行了模拟实验,使用Cloudsim-plus工具。结果表明,该方法能有效降低棕色能源的消耗,同时最大限度地利用绿色能源。
The increase in massive data processing and computing in datacenters in recent years has resulted in the problem of severe energy consumption, which also leads to a significant carbon footprint and a negative impact on the environment. A growing number of IT companies with operating datacenters are adopting renewable energy as part of their energy supply to offset the consumption of brown energy. In this paper, we focused on a green datacenter using hybrid energy supply, leveraged the time flexibility of workloads in the datacenter, and proposed a thermal-aware workload management method to maximize the utilization of renewable energy sources, considering the power consumption of both computing devices and cooling devices at the same time. The critical knob of our approach was workload shifting, which scheduled more delay-tolerant workloads and allocated resources in the datacenter according to the availability of renewable energy supply and the variation of cooling temperature. In order to evaluate the performance of the proposed method, we conducted simulation experiments using the Cloudsim-plus tool. The results demonstrated that the proposed method could effectively reduce the consumption of brown energy while maximizing the utilization of green energy.
