摘要
数据中心行业在发展中形成了自身行业独特的技术经济指标,本文以数据中心全生命周期的不同阶段,结合数据中心行业特点,采用技术经济分析的方法论,通过技术经济指标可量化的衡量与评价,定量化构建了数据中心基础设施技术经济指标体系,进而将这些关键指标(如设计PUE、运行PUE、机架上电率、上架率、建造等级、运维等级等)与经济投资回报评估指标(投资回收期、单位kW造价(IT功率)、单机柜运维成本等)关联,系统地构建数据中心基础设施全生命周期的技术经济评价模型.基于评价模型分析与评价,确定数据中心不同阶段的主要工作方向,量化定义数据中心可持续发展要素与衡量标准,并为数据中心基础设施的选址、投资、建设、运营、改造提供决策依据,保障数据中心的健康可持续发展并为中国数字经济的发展助力.
Abstract
The data center industry has formed its own unique technical and economic indicators in the development of the industry,this paper takes the different stages of the whole life cycle of the data center,combines the characteristics of the data center industry,adopts the methodology of technical and economic analysis,and constructs the technical and economic indicator system of the data center infrastructure in a quantitative manner through the quantitative measurement and evaluation of technical and economic indicators,and then combines the key indicators(e.g.,PUE of the design,PUE,rack power up rate,rack rate,construction level,operation and maintenance level,etc.)with the evaluation indicators of economic return on investment(payback period,unit kW cost(IT power),single cabinet operation and maintenance cost,etc.)The key indicators(such as design PUE,operation PUE,rack power rate,rack rate,construction level,operation and maintenance level,etc.)are then associated with the economic return on investment evaluation indicators(payback period,unit kW cost(IT power),single cabinet operation and maintenance cost,etc.)to systematically construct a technical and economic evaluation model for the entire life cycle of data center infrastructure.Based on the analysis and evaluation of the evaluation model,the main direction of work at different stages of the data center is determined,quantitatively defining the elements and measurement standards of sustainable development of the data center,and providing decision-making basis for the location,investment,construction,operation and transformation of the data center infrastructure,so as to guarantee the healthy and sustainable development of the data center and help the development of China's digital economy.
