...The Green Grid is an association of IT professionals seeking to dramatically raise the energy effi ciency of datacenters through a series of short-term and long-term proposals. This is an update to the very fi rst white paper published by the Green Grid in February 2007 called “Green Grid Metrics: Describing Data Center Power Effi ciency” to refi ne the nomenclature and intent of that paper. In that paper, The Green Grid proposed the use of Power Usage Effectiveness (PUE) and its reciprocal, Datacenter Effi ciency (DCE) metrics, which enable datacenter operators to quickly estimate the energy effi ciency of their datacenters, compare the results against other datacenters, and determine if any energy effi ciency improvements need to be made. Since then PUE has received broad adoption in the industry but DCE has had limited success due to the misconception of what data center effi ciency really means. As a result, this paper re-affi rms the use of PUE but redefi nes its reciprocal as datacenter infrastructure effi ciency (DCiE). This refi nement will avoid much of the confusion around DCE and will now be called DCiE. In the long term, The Green Grid is developing metrics to measure data center productivity as well as effi ciency metrics for all major power-consuming subsystems in the datacenter. To promote these metrics and drive greater datacenter energy effi ciency for businesses around the world, The Green Grid will publish future white papers that provide detailed...

...Green Data Centers: Introduction: Data center is a warehouse where we can store, manipulate, manage and disseminate the data. All the data handling equipment consume a huge amount of energy. To run a data center, it needs power or energy i.e. electricity. It has some effects on surroundingswhich can be either environmental for example CO2 emission, heat etc. or non-environmental decrease in efficiency. In order to make it efficient with both aspects environmental and non environmental there are some mechanisms so that a data center could be energy efficient and environment friendly. We can call it green data centers. Digital data grows tremendously day by day. Growth of data demands of data center for storage and management purposes. According to a report, digital data will increase approximately 44 times of current situation, which increases demand of data centers. Power consumption by data centers will increase accordingly,which causes different problems in addition with CO2 emission. Another report says that CO2 emission from data centers may exceed from any air line CO2 emission by 2020.which is an alarming situation for data centers. So, there is a need of such data centers which are energy efficient as well as environment friendly to meet the needs of present situation. Data centers which will not update their status with the need of time have risk to pay more than double for the same amount of energy requirements. Therefore, there is a need for making data centers...

...CAse Study REPORT PUE DATA CENTER EFFICIENCY MEASUREMENT Introduction One of the metrics used for measuring datacenter efficiency is Power Usage Effectiveness, or PUE. PUE compares the power consumption for the entire facility with the power consumed by the core IT components—servers, storage and network equipment. This ratio illustrates how effectively the power being consumed translates into net compute capacity. Mathematically, the calculation is straightforward: For example, if one watt is being consumed by the servers and one watt is being consumed for the supporting cooling, power back up and other administrative use, the ratio would be 2.0—which is where most datacenters operate. The theoretical ideal PUE is 1.0, where the only energy consumed is for computation. The value of this metric is that it focuses on the non-value added use of power, which in a datacenter is anything that doesn’t compute or store information. PUE = Total Facility Power/ IT Equipment Power Below is an Example to calculate the PUE: Having a facility that uses 100,000 kW of total power of which 80,000 kW is used to power your IT equipment, would generate a PUE of 1.25. The 100,000 kW of total facility power divided by the 80,000 kW of IT power Total Facility Power is defined to be “power as measured at the utility meter”. IT Equipment Power is defined as “the load associated with all of the IT equipment”...

...Discuss three major drivers that motivate organizations to introduce green IT initiatives. The idea of green technology has been around for many years following the trend of green movement which has been raising its hype over the past decade. Green IT refers to the study and practice of using computers and IT resources in a more efficient and environmentally responsible way (McCabe, 2009). It focuses on reducing the environmental impact of industrial processes and innovative technologies caused by the Earth’s growing population. Mainly this means creating fully recyclable products, reducing pollution, proposing alternative technologies in various fields, and creating a center of economic activity around technologies that benefit the environment (Gingichashvili, 2007). Molla (2008) identified three generic forces that can influence the adoption of Green IT — economic forces, regulatory forces, and ethical forces. Economic forces refer to the need for pursuing internal efficiency and market performance (Molla, et al., 2009). A research reveals that cost is the overriding factor for 70% of small businesses IT decision makers to invest in green technologies (Silcock, 2010). Green technology offers the same functionality as traditional technology, and for much the same up-front price. However, it also adds a host of additional benefits in terms of costs, technology and its influence on the organization. For example, green networking switches use less energy and so generate less heat....

...of the most significant energy cost is linked to the use of its data center. Because Bayer is a company whose success depends on the preservation of its intellectual property, they absolutely must keep their privileged information in their own data center and this data needs to have a high level of redundancy to make it reliable (Smith, 2011). A global analysis of the costs of running Intel based data centers, which is the dominant company used in the field, has shown a rise of 400% of the costs linked to cooling and power. This modern dilemma brings forth a brand new kind of trade-off, save costs without sacrificing reliability. This situation can be easily understood when you know that: “93% of companies that lost access to their corporate data centre for ten days or more due to a disaster filed for bankruptcy within one year of the disaster; with 50% of businesses that found themselves without data management for this same time period filed also filed for bankruptcy” (Smith, 2011). This situation is sadly not easily avoidable, research has shown that in 2011, 70% of the data centers experienced disruption related to power usage at enormous costs in productivity loss and technical support (Hengst, 2008). One of the reasons we have chosen Bayer for our study is that it is a proven trailblazer when it comes to improving its processes and efficiently using new technologies to create green data centres. “A green data centre may be thought of...

...problems does data center power consumption cause? Data center power consumption economically affects businesses and environmentally affects society. Operating costs for data centers is very expensive. In the article, "Ubiquitous Green Computing Techniques for High Demand Applications in Smart Environments," the total operating costs, concerning electricity, of all data centers within the U.S. alone exceeded 7 billion dollars in 2010 (Ayala, J., Moya, J., Risco-Martín, J., Sanchez, C., Zapater, M. 2012). The article then explains that data centers consumed 61 billion kilowatt-hours in 2006;the Environmental Protection Agency provided this statistic to the US Congress in a report from 2007 (Ayala, J., Moya, J., Risco-Martín, J., Sanchez, C., Zapater, M. 2012). With this amount of energy being consumed by data centers, it is a cause for concern; consequently, data centers have an impact on the cost of business and negatively impact the environment via carbon footprint. As the carbon footprint grows, there is a need to realign the way businesses looks at managing their data centers. Several companies including Cisco, Dell, Google, HP, IBM, and Intel have announced efforts to reduce the environmental footprint of their product offerings (Chang et al., 2012). Large technology companies are starting to understand that being environmentally friendly is good for the wallet and good public relations. Understanding how to manage and build better data centers with a green foot print becomes...

...Is green computing good for business? As more computing powers are required more electricity is needed. The table below shows the annual cost of electricity for data center servers Year 2000 Year 2007 US $1.3 billion $2.7 billion World Wide $ 3.2 billion $ 7.2 billion Gartner group consultants believe that energy bills, which traditionally account for 10 percent of information technology budgets, could soon account for more than 50 percent. The heat generated from computer rooms is causing equipment to fail. Companies spend as much money to cool the rooms as they spend to power it. Some big companies are facing their power consumption issues looking into environment and saving money. Google, Microsoft, and HSBC are all building data centers that will take advantage of hydroelectric power. For example one Microsoft data center deploys sensors that measure nearly all power consumption, recycles water used in cooling, and use internally-developed power management software. PCs typically stay on more than twice the amount of time they are actually being used each day. One reports claims a 10,000 PCs will cost $165,000 annually in electricity bills if these machines are left on all night. It is believe that about $1.7 billion is wasted each year. Few companies developed PC power management software that locks power settings and automatically powers PCs up right before employees arrive at work. For example one school cut the time its PCs were on from 21 hours to 10...

...start when considering how to reduce data center power consumption? What value of PUE should data center managers strive for? - PUE is simply defined as “Power Usage Effectiveness”. It measures how efficiently data centers use energy. PUE is an important place to start because it makes Google to measure the change in usage effectiveness. The ratio of PUE is total facility energy over IT equipment energy. A PUE of 1.00 would be best, but 1.09 was the lowest estimated value until 2011 as the video says. Data center managers are still striving for that. PUE = IT Equipment Energy + Facility Overhead Energy / IT Equipment Energy 2. Describe the five methods recommended by Google for reducing power consumption. - Measure PUE As I mentioned in Question 1, the industry uses a ratio called Power Usage Effectiveness (PUE) to measure and help reduce the energy used for non-computing functions. To effectively use PUE, it's important to measure often (at least once per second). If the ratio has a 1.00 PUE, it means the energy can be used in the most effective way possible. - Manage airflow Good air flow management is significant to efficient data center operation. By Minimize hot and cold air mixing, Google reduces its power consumption. Google should eliminate hot spots and be sure to use blanking plates (or flat sheets of metal) for any empty slots in the rack. Thermal modeling using computational fluid dynamics (CFD) can help data center managers quickly characterize and optimize...
