The green and virtual data center pdf free download

However, within a particular economy, at a point in time, the variation in pricing should be significantly less. The fluctuation in outside air temperature influences cooling demands, which effects energy consumption and introduces variation in the data center PUE.

Conversely seasonal e. This predicates a need to do real-time data collection and PUE calculations. The situation of less than ideal power metering locations available at the RIT data center is likely common with older data centers.

Figure 1. This figure shows predictable seasonal fluctuations in current draw, with peak consumption during summer months and high demand periods around the end of the school year.. The yearly average of power consumption at point 1 is approx. The observed seasonal variation results in a shift in consumption of about 60A or RIT has an inexpensive and unique data center temperature monitoring system using single wire sensor technology and a php web site that provides real-time temperature data.

This data can be used as to continuously monitor performance of the HVAC controls, and also look for hot spots that represents high server consumption or ineffective cooling layout. Heat map of the RIT data center Operating the data center at a higher mean ambient temperature offers opportunities to reduce the energy consumption associated with cooling. Figure 3 below provides an overlay of the data center temperature with the data center current draw, illustrating the variation in these parameters over a one- day period in February of Figure 3.

Power Statistics from Point 4 in Real Time 3. The data collection systems described above were used for the engineering study. The associated reports provide UPS and generator capacity, total annual power usage, and also break out the HVAC associated power and other auxiliaries. The data summaries from the report were used for the data center analyses that follow. Table 3 below shows an analysis of RIT data center power consumption for and , broken out by sub-system, and also total energy use.

Table 3. Table 4 show the carbon emission projection for the RIT data center. Table 4. This provides an additional economic penalty for excessive deviation from best practice.

Table 5 also gives the calculated Taguchi loss for the RIT data center through , assuming no changes in the existing infrastructure. Table 5. Upgrading to higher efficiency IT equipment reduces total energy consumption but may actually result in an increase in PUE. Increasing the overall data center energy effectiveness reducing non IT related power results in PUE reductions and associated energy savings.

Below are a few examples of changes that can make a positive impact on PUE examples are relative to the baseline. Reduction in lamp fixtures from 19 to 6 results in an improvement of approx 0.

If in addition to turning the reduction in operating fixtures to 6, the remaining fixtures are converted to LED lighting, PUE is reduced by approx 0. Rochester New York is in a temperate climate and can utilize free air- cooling for approximately 5 months of the year. The 45 deg passive cooling limit is set based upon the targeted data center interior control temperature of 65 deg F.

If the data center control temperature is raised to 75 deg F, which would allow passive cooling for approximately 7. This improvement results in a PUE improvement of 0.

Increasing equipment operating temperatures raises a concern of reduced equipment reliability or durability. Experience at RIT indicates that the current physical life of IT equipment is longer than the useful life due to technology obsolescence. The standard form of the Taguchi loss function penalizes adverse process behavior and variation relative to a performance benchmark.

We have suggested that the CO2 emission associated with benchmark data center PUE is an appropriate benchmark. The employed form of the Taguchi loss function penalizes data center performance deviation that significantly exceeds the variation between best practice and state of the art benchmarks, resulting in increasing cost associated with non-compliance.

These results indicate that the RIT data center infrastructure is out of date and requires significant improvements, if not complete overhaul, in order to achieve best practice and zero the loss function.

The loss function formulation also results in no economic penalty when the data center is at benchmark performance. The justification for this is that advancement beyond best practice is often not cost effective and there may be better more cost effective opportunities to reduce carbon emissions elsewhere.

Consortium Green Grid. Consultants, R. Hence it has become very crucial and unavoidable to develop a system which can reduce the cost Using green technology has become imperative today.

The ugly side of this is the harm these products or new technologies are doing to our environment. This raises the importance of using green technology all the more. Green Technologies The application of one or more of environmental science, green chemistry, environmental monitoring and electronic devices to monitor, model and conserve the natural environment and resources, and to curb the negative is known as Green Technology.

However, with new Green Data Center Cooling Solution technology available, data centers can be optimized to reduce their energy usage. By using green technology, large IT corporations will take a step ahead in saving the environment and make the earth free from any danger. Destroying environment any further can lead to situations which can be hazardous and irreversible.

Green Technology helps reduce the use of fossil fuel. It is expected that energy production from green technology will be higher than fossil fuel sources of energy like oil, and gas in the future. Using green technology will become not only important but mandatory too in the coming years because of limited Non Renewable energy sources. Green technology encourages the concept of cleanliness, freshness and also promotes new dimensions.

The sooner we realize the importance of using green technology, the better it will be for our planet and its environment. Shows methods of Green Computing In this age of ever advancing technologies, new efficiencies are developed within the equipment ensure that most of the energy goes into the IT load, instead of being lost in the powering and cooling of the equipment. Environmentally friendly technologies are coming into their own, for example, designing datacenters powered by renewable energy sources.

As 21st century belongs to computers, and electronic items, energy issues will get a serious ring in the coming days, as the public debate on carbon emissions, global warming and climate change gets hotter.

Although this development has helped the human race, mismanagement has led to new problems of contamination and pollution. Faster processors historically use more power. Inefficient CPU's are a double hit because they both use too much power themselves and their waste heat increases air conditioning needs. The technical process acquired during the last century has posed a new challenge in the management of wastes. Green Computing Green computing is the practice of using computing resources efficiently.

Modern IT Systems rely upon a complicated mix of people, networks, and hardware, as such, a Green computing initiative must be systemic in nature, and address increasingly sophisticated problems. Green computing has become the utmost requirement to protect environment and save energy, along with maintaining operational expenses in today's increasingly competitive world. Currently large IT corporations are working on implementation of the green computing practices.

It has been seen that the power consumption of the green energy data center system is half that of a conventional data center, and green energy accounts for another half for driving. The data center is green and energy saving, and the profit margin of the data center is improved.

What is Green Data Center? A green data center is an enterprise class computing facility that is entirely built, managed and operated on green computing principles providing the same features and capabilities of a typical data center by using less energy and space.

It can be considered as a transformation that encompasses technical innovation, operational improvements, new design principles, changes to the relationship between IT and business, and changes in the data center supply chain by using Green Technologies. Basically a green data center comprises of a utility power source, a facility electrically connected to the utility power source, a renewable energy provider and an IT equipment electrically connected to the renewable energy provider, wherein the total power received by the IT equipment is not less to the utility power provided by the utility power source thereby achieving the effect of carbon-reducing and energy-saving.

This step includes monitoring and measuring the consumption of energy for the entire enterprise The e a e et i s that a help i a al zi g the g ee ess of a e isti g data e te. Based on this measurement, corrective measures can be taken to transition to a GDC. Carbon Foot Print A carbon footprint is historically defined as "the total sets of greenhouse gas emissions caused by an organization, event, product or person.

Carbon footprint spectrum of definitions ranges from direct CO2 emissions to full life-cycle greenhouse gas emissions and not even the units of measurement are clear. By customizing innovative power and cooling strategies to the unique climate where our data centers operate. There is more emphasis on the power and cooling infrastructure.

The power scheme being used currently in the enterprise will change with the increase and decrease in usage of energy. Apart from the benefit of reducing the operating costs by reducing energy costs, practices that reduce consumption of energy are also being used. Different Methods Of Greening a Data Center Green strategies and technologies exist today to help optimize space, power, cooling and resiliency while improving efficiency and reducing costs at the same time, helping to position companies for growth and enabling them to meet expanding business needs.

Although the e is lea l o si gle ight a to eate a g ee data e te , e pe ts elie e that the most productive first step is to conduct a best practices assessment and energy audit. Turning off servers that are not doing any work and also by turning off computer room air conditioning units in areas that are overprovisioned for cooling. Most important aspect to be implemented is reducing cooling requirements of the data center.

There are a number of factors that should be considered in developing a plan for improving power and cooling efficiency by reducing the heat generated in the data center. Improvements in rack and room layout can increase energy efficiency with relatively low upfront investment. Water-side economizers Water-side economizers, utilize outside air to directly cool the chilled water and can further reduce the energy required to run the data center chillers.

Recycling of energy can be done by augmenting capacity and efficiency of chilled water systems with thermal storage systems that store energy generated at night, when chillers typically operate more efficiently, and then release this energy during the day. When the systems are larger and more amenable to taking advantage of no-cost cooling, outside air temperatures are sufficiently low to provide some or all of the cooling requirements. Companies can save energy and gain cooling capacity by relaxing stringent relative humidity and temperature requirements for their data centers.

Refrigerants used for cooling Safety becomes a key concern when the source of cooling moves close to sensitive electrical equipment so refrigerant is an ideal choice for high-density applications. Because refrigerant turns into a gas when it reaches the air, so it will pose a safety hazard and a leak would not damage IT equipment. Refrigerant solutions also provide an incremental energy efficiency savings of between 25 percent and 35 percent, based on kilowatts of cooling capacity per kW of heat load.

Dynamic Monitoring and Management module is used for monitoring and managing the cooling and energy efficiency of data center. After taking a measurement survey, IBM combines sensors and measurement survey results for ongoing analysis and reporting.
