1. What is PUE, and why is it an important place to start when considering how to reduce data center power consumption? What value of PUE should data center managers strive for?

PUE stands for Power Usage Effectiveness. It is the ratio of total facility energy to IT equipment energy. This measurement is important because it displays how effectively the company delivers power to the IT equipment. If the company is not delivering its energy effectively, they could incur a great deal of additional overhead costs. Companies want their PUE to equal or get close to 1.00. So, the PUE ratio would be 1.00/1.00=1.

2. Describe the five methods recommended by Google for reducing power consumption.

1). Measure PUE Reducing overhead by effectively distributing power and cooling. 2). Manage Airflow:
Managing airflow is yet another way to reduce a data center’s energy load by reducing the mixing of hot and cold air. One way to measure this is through CFD (Computational Fluid Dynamics) which shows where “hot spots” are located and how the airflow is directed. 3). Adjust Thermostat:
By increasing the temperature and reducing the amount of energy expended on air conditioning, Google saves thousands of dollars annually. Even just increasing the temperature by a few degrees makes a huge difference in annual energy consumption. 4). Utilize Free Cooling:
Using ambient temperatures outside the data center to provide free cooling and thereby reducing energy consumption. For example, a cooler climate such as Iceland is a more desirable location than a hot and humid one such as Florida. Additionally, using techniques such as evaporative cooling can reduce energy consumption by use of water. 5). Optimize Power Distribution:
Google has reduced the number of electrical conversion stages (AC to DC) needed to supply electricity to components...

...1a – Google Data Center 1. What is PUE, and why is it an important place to start when considering how to reduce data center power consumption? What value of PUE should data center managers strive for? Power Usage Effectiveness (PUE) is a measure to determine the energy efficiency of a data center. It is the ratio between the energy of the system and the energy of the IT equipment in the data center. TOTAL FACILITY ENERGY PUE = --------------------------------------- IT EQUIPMENT ENERGY It is the ratio of the energy supplied to the entire Data Center and the energy consumed by the IT equipment. Whether to feed the entire plant, we need twice the minimum required to own IT equipment, we have a PUE 2. It allows to calculate the efficiency of the power supply and cooling IT equipment.. A PUE of 2.0 means that for every watt of IT power, an additional watt is consumed to cool and distributes power to the IT equipment. A PUE of 1.0 is considered ideal. A closer PUE of 1.0 means that almost all the energy is used to compute. For use PUE to be effective, should be measured often. If you occasionally makes the information will not be realistic. Ideally, measured as quickly and frequently as every second way. The higher the frequency, the more significant the results. 2.

Computing Goes Green

...With world leaders currently convening high-level negotiations on how best to address the rising threat of global warming, and public apprehension about the phenomenon at an all-time high, it's encouraging to note several recent developments coming from the high-tech sector. It's about time. Our ever-shrinking world is abuzz with activity attempting to address the manmade rise of greenhouse gases. Eco-visionary James Lovelock published a radical idea in Nature to increase ocean uptake of CO2 through giant ocean tubes. New Zealand has kicked off an ambitious plan to get 90% of its energy from renewable sources by 2025. JC Penney, Office Depot and Kohl's have announced green building plans. In May, General Electric said it had doubled sales from environmentally friendly products, to $12 billion over, in two years. One need only take a look at any online discussion thread of green issues to see anxiety, and often outright ridicule, about the sizable ecological impact so many of us Web surfers are having. Computers are hard to (and rarely) recycled, and when they are, it's typically in developing nations by people without proper training or safety gear. Often they are children. That's distressing, because today's computers are made with a sizable amount of lead, cadmium, brominated fire retardants and plastics that can leach toxic breakdown products. While processor speed has faithfully followed Moore's Law, energy use has also swelled, as more and more people are able......

...Green computing 1 Green computing Green computing, green IT or ICT Sustainability, refers to environmentally sustainable computing or IT. In the article Harnessing Green IT: Principles and Practices, San Murugesan defines the field of green computing as "the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment."[1] The goals of green computing are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Many corporate IT department have Green Computing initiatives to reduce the environmental impacts of their IT operations.[2] Research continues into key areas such as making the use of computers as energy-efficient as possible, and designing algorithms and systems for efficiency-related computer technologies. Origins In 1992, the U.S. Environmental Protection Agency launched Energy Star, a voluntary labeling program that is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies. This resulted in the widespread adoption of sleep mode among consumer electronics. Concurrently, the Swedish organization TCO Development launched the TCO...

...indeed beneficial and appropriate, the process and procedure of becoming green is anything but easy. Firstly, turning green is largely not a legal requirement, but a voluntary process. Thus, even though LEED (which is by far the more publicly known green certification standard) governs the certification of the green management effort, it is not a compulsory condition for practitioners to go green. Secondly, even with the encouragement of incentives to comply, practitioners are skeptical in becoming green due to: (a) a lack of true understanding of the benefit of ecologically friendly procedures (the practice of profits versus the theory of benefits); (b) lack of short term gain in life cycle costing (practitioners want instant incentives); and (c) mostly, because it is not a legal requirement for the vast majority of municipalities. Keywords: Green management, green business practices, barriers toward green management, encouragement & incentives for green management, LEED Certification. RESUMEN La gestión ambiental sostenible y el tornarse ecológico no es tan claro ni factible como lo pregona la prensa. Mientras que volverse ecológicamente “verde” es sin duda beneficioso y apropiado, el proceso y el procedimiento de hacerlo es todo menos fácil.

Green Cloud Computing

...infrastructure for running HPC, enterprise and Web applications. However, the growing demand of Cloud infrastructure has drastically increased the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high operational cost, which reduces the profit margin of Cloud providers, but also leads to high carbon emissions which is not environmentally friendly. Hence, energy-efficient solutions are required to minimize the impact of Cloud computing on the environment. In order to design such solutions, deep analysis of Cloud is required with respect to their power efficiency. Thus, in this chapter, I discuss various elements of Clouds which contribute to the total energy consumption and how it is addressed in the literature. I also discuss the implication of these solutions for future research directions to enable green Cloud computing. The paper also explains the role of Cloud users in achieving this goal.
