canada goose coats on sale Green Grid Seeks to Rein In Misuse of PUE canada goose uk outlet Energy Efficiency Rating canada goose coats on sale

canada goose coats Power Usage Effectiveness, or PUE, has become something of an untamed beast in the data center industry. The standard, developed by the IT industry group The Green Grid and released to the public four years ago, has become the de facto standard of energy efficiency a «miles per gallon» type rating for green data centers. canada goose coats

canada goose deals Now the standard Canada Goose Coats On Sale has fallen victim to canada goose factory sale its own cheap Canada Goose success. canada goose deals

buy canada goose jacket Data center owners and operators are constantly touting their Canada Goose sale PUEs a number that measures how much canada goose of the energy entering data centers is providing compute power as canada goose clearance sale opposed to lighting, cooling and other support services in what on the surface is a promising «race to the top» for the greening of data centers. buy canada goose jacket

canada goose The problem Canada Goose online lies not with the standard, but with how it is applied. Not only did the original PUE guidance published by canadian goose jacket The Green canada goose black friday sale Grid in 2007 leave buy canada goose jacket out detailed methods for how to measure PUE, it also neglected to clarify that PUEs are not a reliable basis for comparing two data centers. canada goose

Canada Goose Jackets «PUE https://www.thecanadagooseoutlet.com is the most used, most abused metric out there,» Vince Renaud, Vice President of The Uptime Institute Professional Services, explained last week at the Uptime Institute Symposium. «Use it for what it supposed to be: individual data centers, measuring against yourself, canada goose uk shop not against this one over thecanadagooseoutlet here or this one canada goose store over there. Green Buildings Council, and other buy canada goose jacket cheap groups, yesterday took steps to rectify the problems with PUE, publishing a new white paper that clearly delineates how to measure PUE, giving the IT industry four different ways to measure energy efficiency, with varying canada goose uk black friday degrees of accuracy. Canada Goose Jackets

canada goose black friday sale The white paper introduces a couple of useful additions to the standard. First and foremost it spells out exactly how PUE should be measured, but breaks the standard down to four categories, ranging from relatively simple measurements that provide a performance snapshot to more accurate and sophisticated measures Canada Goose Parka to provide detailed performance data. canada goose black friday sale

canada goose store The white uk canada goose paper also gently but clearly spells out that PUE is not a comparison tool: It should be noted that caution must be exercised when an organization wishes to use PUE to compare different data centers, as canada goose coats it is necessary to first conduct Canada Goose Outlet appropriate data analyses to ensure that other factors such as levels of reliability and climate are not impacting the PUE. canada goose store

buy canada goose jacket cheap Though the white paper Canada Goose Jackets serves to clarify PUE measurement, It likely that it won simply end the misuse of PUE ratings. But in solidifying the standard and urging further improvement on data center energy efficiency, The Green Grid has continued its efforts to keep the race to the top on the right path buy canada goose jacket cheap.
