对数字服务的需求正在显著增加。在数据中心、机械和电气基础设施层面解决能效问题开始受到回报递减规律的影响。信息技术设备，特别是服务器，在整个设施能源消耗和环境影响中占很大一部分，因此，从循环经济的角度来看，这是一个重要的机会。为了减少服务器对环境的影响，重要的是要认识到服务器的制造、操作和处置对环境的影响。这项工作为使用重新制造和翻新的服务器更新服务器对能源效率和环境的影响提供了新的见解。这项研究考虑了CPU设计趋势的最新变化和摩尔定律。该研究测量并分析了重新制造的服务器与具有不同硬件配置的新服务器的使用阶段能耗。案例研究被用来从经济和环境角度评估翻新服务器更新的潜在影响。
Demand for digital services is increasing significantly. Addressing energy efficiency at the data center mechanical and electrical infrastructure level is starting to suffer from the law of diminishing returns. IT equipment, specifically servers, account for a significant part of the overall facility energy consumption and environmental impact, and thus, present a major opportunity, not the least from a circular economy perspective. To reduce the environmental impact of servers, it is important to realize the effect of manufacturing, operating, and disposing of servers on the environment. This work presents new insights into the effect of refreshing servers with remanufactured and refurbished servers on energy efficiency and the environment. The research takes into consideration the latest changes in CPU design trends and Moore's law. The study measures and analyzes the use phase energy consumption of remanufactured servers vs new servers with various hardware configurations. Case studies are used to evaluate the potential impact of refurbished server refresh from an economic as well as environmental perspectives.
