Discover the green Data center of world-renowned technology companies

The Facebook data Center is located in the Oregon State area of Eastern Cape.

FedEx's data center is located in Colorado State's Colorado Springs.

HP's data center is located in Fort Collins, Colorado State.

The new data Center building of the U.S. vantage Company is located in Santa Clara, California.

The Verne Global Company's data center is located in the Reykjavik area of Iceland.

In the information explosion today, global data stocks are expanding at an alarming rate. According to Internet Data Center research, as social media and cloud computing technology, in the next 10 years, the total amount of global data will increase 44 times times, which means that more data storage centers will appear.

However, data storage centers are flooded with servers that work 24 hours, and air conditioners that work uninterrupted because of cooling requirements, which will lead to an increase in greenhouse gas emissions. In addition, in the global high energy prices today, a large amount of energy consumption is not conducive to environmental protection. Some green-minded technology companies have long recognized this, while controlling energy consumption, while still looking for ways to make data storage centres more efficient, from developing new server chips to designing more heat-dissipating buildings.

There is no specific way to make the data storage center more environmentally friendly, including Google, Facebook, Amazon, Twitter, Yahoo, Apple and other well-known technology companies are still groping, but in recent days, the United States "wired" The magazine evaluated 9 technology companies that did the best job of building Green data centers in 2011. The basis of evaluation is mainly based on Pue value. Pue is a shorthand for power Usage effectiveness and an indicator of data center energy efficiency, meaning that all the energy consumed by the data center is compared to the energy used by the IT load, so pue is a ratio, the benchmark is 2, and the closer 1 indicates the better the level of energy efficiency. At present, most technology companies around the world are Pue between 2.0 and 3.0 of the data centers.

1. Facebook

The Facebook data Center is located in the Oregon State area of Eastern Cape. The region's plateau desert terrain means that the climate is very dry, but rarely hot, and the ventilation is very good, so Facebook can maximize the use of external mobile air to the data Center for "free cooling." On the second floor of the data center, there is a wide space for the size of an aircraft carrier, which mainly acts as a ventilation duct. When the outdoor temperature rises, the steam chamber in the data center can use the temperature difference to spray the water vapor into the air, thereby reducing the indoor air temperature.

2, FedEx

FedEx's data center is located in Colorado State's Colorado Springs. The region is located in the Rocky Mountains, and dry air is also an ideal "free" air conditioner. FedEx expects the design to reduce the amount of air-conditioning electricity consumed at least 5,000 hours a year, accounting for about 57% of the year.

3, Google

Google's new data center is located in Hamina, Finland. Google turned a paper mill built in the 50 's into a data center full of cutting-edge technology. The data center uses seawater to cool down, and its cooling principle is the heat conduction mechanism. Google injected seawater into the heat conduction system to cool the data center, which will be discharged into the sea after the heat has been transmitted. However, in order to avoid heat pollution, these heat-carrying seawater will be mixed with ordinary seawater to reduce water temperature before being discharged.

4. Harris Company

The US company is the leading international communications and information technology company. The company was awarded the 2011 Green Enterprise IT Award by uptime Cato for its own development of circulating cooling water system, and its data center is located in Fort Harrison, Virginia State. The system uses ultraviolet and electrical pulse technology to control corrosion, oxidation and biochemical contamination.

5, HP

HP's data center is located in Fort Collins, Colorado State. In addition to exploiting the natural conditions of the Rockies, the data center is equipped with thousands of environmental sensors to dynamically adjust the cooling system by directly feeding the environment parameters to the central management system. In the diagram, you can see that there is a row of plastic film on top of each server shelf, and its main function is to prevent the cold air entering the server and the heat emitted from the mixture.

6, IBM

IBM's data center is located in the Oakland area of New Zealand. The data center uses advanced environmental monitoring systems and power management systems to monitor the use of electricity, hydro and diesel in real time. In addition, it also makes full use of air flow and water vapor from the cooling towers to cool down.

7, Tieto

Stack Information Technology Co., Ltd. (Tieto) is a leading European IT service provider whose new data center is located in Espoo, Finland. The company also won the 2011 Green Enterprise IT Award from uptime Cato, due to the use of waste heat to provide heat to 1500 households in the area. The company has chosen its data center to be built near a power plant, so its waste heat can be pumped into the power plant's district heating network, a move that could reduce carbon dioxide emissions by 10,000 tonnes a year.

Pue value: 1.2 to 1.3

8, Vantage

The new data Center building of the U.S. vantage Company is located in Santa Clara, California. The building received platinum certification from the American Green Building Association, the highest level of seriousness in the agency. The new data centre not only attaches great importance to the protection and utilization of resources, all of its building materials are low toxicity, and construction waste is well handled.

9, Verne Global

The Verne Global Company's data center is located in the Reykjavik area of Iceland. Its data centers are very unique and are declared to be zero-emitting carbon. The entire central building relies mainly on geothermal and hydro power to provide the electricity needed, which is very cheap and plentiful in Iceland. In addition, it took advantage of Iceland's perennial dry, cold climate to cool down.
