Nuvens híbridas, eficiência energética e custos desafiam ... Na semana passada, conduzi uma conferência sobre cloud computing que me levou muito além do que costumo falar habitualmente. O evento DatacenterDynamics concentrou-se na parte física das instalações do Data Center e das infraestruturas de computação. Eu falei sobre "TI como o Provedor de New Service Cloud" e concluí que toda a conferência foi uma experiência esclarecedora.
Na maioria das conferências sobre computação em nuvem, o mais próximo que se chega do hardware são os fornecedores de servidores; nessa conferência houve uma abundância de empresas de UPS (sigla em inglês para fonte de alimentação ininterrupta de energia), fabricantes de cabos, instaladores de ar-condicionado, e até mesmo empresas de construção. E deixe-me dizer: os participantes tinham temas muito específicos em suas mentes. Por exemplo, a sessão antes da minha era "ASHRAE (Sociedade Americana de Aquecimento, Refrigeração e Ar-condicionado): estão-se expandindo os limites da temperatura e da umidade - mais uma vez".

Please note: PUE: A Comprehensive Examination of the Metric supersedes all prior white papers and consolidates all of the new and previously published content that The Green Grid has developed related to PUE. Editors: Christian Belady, Microsoft Contributors: Andy Rawson, AMDJohn Pflueger, DellTahir Cader, Spraycool The Green Grid is an association of IT professionals seeking to dramatically raise the energy efficiency of data centers through a series of short-term and long-term proposals. This is an update to the very first white paper published by the Green Grid in February 2007 called "Green Grid Metrics: Describing Data Center Power Efficiency" to refine the nomenclature and intent of that paper.
2008 - Data Center Energy Forecast. Major new state funding for reducing web server-farm power. In early March, the California Energy Commission (CEC) announced that it was awarding a grant of $500,000 to Berkeley Lab to conduct research designed to reduce the energy use of server farms in California by 30 percent. About 17 percent of the nation's server farms are located in the San Francisco Bay Area and Silicon Valley, requiring about 80 megawatts of power to run. Saving 30 percent of this would free up to 24 megawatts of power. "Any megawatt savings would be really helpful to California in the next few summers," says Commissioner Arthur Rosenfeld, chair of the Commission's Research, Development, and Demonstration Committee. "Twenty-four megawatts of electricity running continuously will supply 24,000 average California homes.
" There are three parts to the research. The first will characterize the power load drawn by data centers in California -- determining where the data centers are in the state and how much electricity they use. Data center energy use: truth versus myth. Digital Economy's Demand for Steady Power Strains Utilities Data Servers Crave Power: High-tech Electricity Needs Amplify Crisis Net Blamed as Crisis Roils California At the height of the electricity crisis of 2001, Californians were greeted with headlines like these over their morning coffee. One of the biggest misconceptions about the crisis was the role played by the energy use of computers and other internet-related hardware.
But early in 2001, research by Jon Koomey of Berkeley Lab's Environmental Energy Technologies Division (EETD) had showed that widely discussed estimates of the energy use of computer and networking-related hardware were exaggerated. New information on data centers Questions persisted about the use of energy by a prominent type of facility that has become more common since the expansion of the internet as a commercial entity: the data center, also known as the web server farm. "Many reports of data center energy use are exaggerations," says Mitchell-Jackson. Data Center Energy Efficiency Calculator.
