Key Technologies for Green Data Center

With the repaid development of multi-media and network, information are generated and spread quickly than before. The industry is expected to meet the needs by producing high performance CPU and high-density disk. But dramatic increase in energy requirements becomes a new challenging. Energy and human cost become the major parts of data center. More and more vendor provides efficiency products, such as MAID(Massive array idle disk). SPEC has developed a power benchmark for single server (SPECPowerssj2008), SNIA has developed a green storage measure standard. In this paper, we summary several technologies to reduce energy consume of data center. These technologies can be divided into three levels: power and refrigeration, green components, intelligence energy management. At the last part of paper, we introduced the test standard of energy usage of server and storage.
