摘要
互联网数据中心(IDC)从规划建设、运行维护到经营管理,都是复杂的系统工程,涉及多个行业、众多子系统和多个专业。传统数据中心能耗量大,能源利用率低。由于IT设备制作和应用技术的功能越来越强大,集成度日益提高,安装服务器的单机架平均耗电量为7~10 kW逐渐常见。机房精密空调机组采用传统的'先冷环境、再冷设备'模式,不但不能满足高密度机架和机房的需求,还容易造成机房热岛效应的存在,而且加大了空调制冷负荷,将浪费更多电能。根据测算,IDC耗电量占其总运营成本的45%~60%。因此,绿色环保节能数据中心作为下一代数据中心建设的核心理念之一,对未来数据中心建设极其重要。因此,将从中国电信中山分公司数据中心(IDC)机房发生的实际案例出发,对IDC机房产生热岛效应的原因、整改优化和节能效果进行分析,希望能为建设绿色环保节能的数据中心(IDC)提供助益。
The Internet data center(IDC)is a complex system engineering,involving many industries,many subsystems and many specialties,from planning and construction to operation and maintenance.Traditional data centers have high energy consumption and low energy utilization.Due to the increasingly powerful functions of IT equipment production and application technologies,the degree of integration is increasing,and the average power consumption of a single rack for installing servers is gradually becoming common.The precision air-conditioning unit in the computer room adopts the traditional'first cooling environment and second cooling equipment'model.Not only can it not meet the needs of highdensity racks and computer rooms,it is also easy to cause the existence of the thermal island effect of the computer room,but also increases the air-conditioning refrigeration load will waste more electricity.According to calculations,IDC power consumption accounts for 45%to 60%of its total operating costs.Therefore,as one of the core concepts of the next generation data center construction,the green,environmental,energy-saving data center is extremely important for the future data center construction.Therefore,from the actual case of data center(IDC)room of China Telecom Zhongshan Branch,we will analyze the reasons for the heat island effect,rectification optimization and energy-saving effects of IDC computer room,hoping to build a green,environmentally friendly and energy-efficient data center(IDC)provide help.
