Power Usage Effectiveness
Power usage effectiveness (PUE) is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead that supports the equipment). PUE is the ratio of the total amount of energy used by a computer data center facility to the energy delivered to computing equipment. PUE is the inverse of data center infrastructure efficiency. PUE was originally developed by a consortium called The Green Grid. PUE was published in 2016 as a global standard under ISO/IEC 30134-2:2016 An ideal PUE is 1.0. Anything that isn't considered a computing device in a data center (e.g. lighting, cooling, etc.) falls into the category of facility energy consumption. : \mathrm = = 1 + Issues and problems with the power usage effectiveness The PUE metric is the most popular method of calculating energy efficiency.

Data Center
A data center (American English) or data centre (British English)See spelling differences. is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a small town. History Data centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center.Old large computer rooms that housed machines like the U.S. Army's ENIAC, which were developed pre-1960 (1945), were now referred to as "data centers". Early computer systems, complex to operate and ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Server Immersion Cooling
Immersion cooling is a cooling technique often applied as an IT cooling practice, by which computer electronics, including complete servers and storage devices, are fully submerged in a thermally conductive but electrically insulating liquid or coolant. This practice is highly effective because liquid can absorb a lot more heat energy and is more efficienty to move compared to air. Fluids suitable for immersion cooling have electrically insulating properties to ensure that they can safely come into contact with electronic components, which means that these electronics are functioning within the liquid. In general, there are two main liquid categories which are used for this application, Hydrocarbons like various types of oils and esters and so-called fluorocarbons which are fully engineered liquids. Immersion applications and the used liquids are again divided into single- and two-phase applications. Single phase immersion works by mechanically (pumping) or naturally circulat ...

Water Usage Effectiveness
Water Usage Effectiveness (WUE) is a sustainability metric created by The Green Grid in 2011 to attempt to measure the amount of water used by datacenters to cool their IT assets. To calculate simple WUE, a data center manager divides the annual site water usage in liters by the IT equipment energy usage in kilowatt hours (Kwh). Water usage includes water used for cooling, regulating humidity and producing electricity on-site. More complex WUE calculations are available from The Green Grid The Green Grid is a nonprofit, industry consortium of end-users, policy-makers, technology providers, facility architects, and utility companies collaborating to improve the resource efficiency of data centers.

IT Energy Management
IT energy management or Green IT is the analysis and management of energy demand within the Information Technology department in any organization. IT energy demand accounts for approximately 2% of global emissions, approximately the same level as aviation, and represents over 10% of all the global energy consumption (over 50% of aviation's energy consumption). IT can account for 25% of a modern office building's energy cost. At one point, the main sources of manageable IT energy demand were PCs and Monitors, accounting for 39% of energy use, followed by data centers and servers, accounting for 23% of energy use.Steve Kleynhans, VP Computing, Gartner presentation “the Green PC Environment” - presentation, New York, November 2007 In 2006, US IT infrastructures consumed an estimated 61 billion kWh of energy, totaling to a cost of $4.5 billion. Significant opportunities exist for Enterprises to optimise their IT energy usage. Computers, data centers and networks consume 10% of t ...

Green Computing
Green computing, green IT, or ICT sustainability, is the study and practice of environmentally sustainable computing or IT. The goals of green computing are similar to green chemistry: reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, the recyclability or biodegradability of defunct products and factory waste. Green computing is important for all classes of systems, ranging from handheld systems to large-scale data centers. Many corporate IT departments have green computing initiatives to reduce the environmental effect of their IT operations. Yet it is also clear that the environmental footprint of the sector is significant, estimated at 5-9% of the world's total electricity use and more than 2% of all emissions. Data centres and telecommunications will need to become more energy efficient, reuse waste energy, and use more renewable energy sources. They can and should become climate neutral by 2030. Origins In 1992, the U.S. Enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gpue
Green Power Usage Effectiveness (GPUE) is a proposed measurement of both how much sustainable energy a computer data center uses, its carbon footprint per usable kilowatt hour (kWh) and it uses its power; specifically, how much of the power is actually used by the computing equipment (in contrast to cooling and other overhead). It is an addition to the power usage effectiveness (PUE) definition and was first proposed by Greenqloud. The Green Grid has developed the Power Usage Effectiveness metric or PUE to measure a data centers' effectiveness of getting power to IT equipment. What the PUE tells in simple terms is how much extra energy is needed for each usable kWh for the IT equipment due to the power going into cooling, power loss etc. and it's a simple formula (in theory): PUE = Total Facility Power/IT Equipment Power The PUE can change depending on where measurements are made, when they are made and the timespan the measurements are made in.

Performance Per Watt
In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. This rate is typically measured by performance on the LINPACK benchmark when trying to compare between computing systems: an example using this is the Green500 list of supercomputers. Performance per watt has been suggested to be a more sustainable measure of computing than Moore’s Law. System designers building parallel computers, such as Google's hardware, pick CPUs based on their performance per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. Spaceflight computers have hard limits on the maximum power available and also have hard requirements on minimum real-time performance. A ratio of processing speed to required electrical power is more useful than raw processing speed. D. J. Shirley; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fortune 100
The ''Fortune'' 500 is an annual list compiled and published by ''Fortune'' magazine that ranks 500 of the largest United States corporations by total revenue for their respective fiscal years. The list includes publicly held companies, along with privately held companies for which revenues are publicly available. The concept of the ''Fortune'' 500 was created by Edgar P. Smith, a ''Fortune'' editor, and the first list was published in 1955. The ''Fortune'' 500 is more commonly used than its subset ''Fortune'' 100 or superset ''Fortune'' 1000. History The ''Fortune'' 500, created by Edgar P. Smith, was first published in 1955. The original top ten companies were General Motors, Jersey Standard, U.S. Steel, General Electric, Esmark, Chrysler, Armour, Gulf Oil, Mobil, and DuPont. Methodology The original ''Fortune'' 500 was limited to companies whose revenues were derived from manufacturing, mining, and energy exploration.
