電力使用効率（PUE）
Your Power Usage Effectiveness (PUE) In 2007, The Green Grid published its very first white paper regarding energy efficiencies in data centers. “Green Grid Metrics: Describing Data Center Power Efficiency” proposed the use of Power Usage Effectiveness (PUE) and Datacenter Efficiency (DCE), now Data center Infrastructure Efficiency (DCiE), as a means to enable data center operators to quickly estimate the energy efficiency of their data centers, compare the results against other data centers, and determine if any energy efficient improvements could be made. Since 2007 PUE has been massively adopted by the data center industry and is now used as a standard in measuring power usage. According to the Uptime […]
グリーングリッド：無料の冷却のためのリソース
Free Air Cooling is Catching on in The Data Center Industry It seems that everyone in the data center industry these days is looking to find the most efficient and cheap way to run their facility. It makes sense when you think about it. Why spend more and narrow your profit margin, when you could be actively seeking ways to reduce the cost of keeping your server farm efficiently up and running. With reducing project budgets and more economic pressure, data center management are considering all savings opportunities and free cooling is one of them. Data center industry leaders are leading this trend. EBay is currently running their data […]
ソーラーアレイを搭載したグリーンデータセンター
A Green Data Center Powered by Solar Arrays: Is It Worth All the Hype? Solar power is quickly becoming the hot new topic for the green data center, and better data center operations. Nothing else quite shouts “I’m going green” like installing a couple hundred acres of solar panels next to your power hungry, coal guzzling data center. Few things are more capable of blatantly making you look like you’re environmentally conscious. In an age where everyone is trying to care about the planet, it seems that installing a solar array is the industries way of doing it. But how effective and efficient are these solar panels really? Apple, Facebook, […]
データセンタースポットライト：EBay – Project Mercury
Spotlight Data center: EBay – Project Mercury Why Phoenix? Why would anyone build a data center in the middle of a desert that reaches temperatures of up to 119F°? And how in the world are they going to cool it efficiently? I know these were the first questions that popped into my mind when I first heard about EBay’s new Project Mercury data center, and my guess is you were probably thinking the same things. EBay is currently in the midst of a major overhaul; moving away from renting and leasing facilities and into owning their own, maximizing their ability to better control efficiency. With the consolidation of 11 data […]
