Energy Logic is a vendor-neutral approach to achieving energy efficiency in data centers. Developed and initially released in 2007, the Energy Logic efficiency model suggests ten holistic actions – encompassing IT equipment as well as traditional data center infrastructure – guided by the principles dictated by the "Cascade Effect." ==Energy Logic Assumptions== The first iteration of the Energy Logic model was introduced by Emerson Network Power on November 29, 2007.〔“Emerson Network Power Introduces New Approach to Data Center Energy Optimization,” Press Release from Corporate Web Site ()〕 Described as a “new approach to energy optimization,” the model was developed in response to industry feedback suggesting a growing emphasis on promoting efficiency initiatives, without compromising the performance and reliability of the data center.〔"Emerson Delivers Free Energy Logic Blueprint for Building a Power Efficient Data Center”, "InfoWorld" ()〕 The Energy Logic data center efficiency model was developed based on research and modeling of a 5,000 square foot data center, including average IT equipment densities, common data center and facility infrastructures (power, cooling, etc.) and their collective energy draw. Energy draw for the 5,000 square foot data center model was based on the following assumptions:〔“Energy Logic: Reducing Data Center Energy Consumption by Creating Savings that Cascade Across Systems,” White Paper ()〕 * Server refresh rate: 4 to 5 years * * Data center has mix of servers ranging from new to 4-years old * No virtualization or blades * No high-density loads * * Average density: 3 kW/rack (120 W/sq. ft.) * Total compute load: about 600 kW * UPS configuration: 2x750 kVA, 1+1 redundant * Hot-aisle/cold-aisle configuration * Floor-mount cooling connected to building chilled water plant * MV transformer (5 MVA) at building entrance with switchgear 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Energy Logic」の詳細全文を読む スポンサード リンク
