Data center migration, cloud computing data center involves resource space, electricity, water resources and other factors. There is no doubt that the data center has caused great pressure on the local ecosystem. Turning the data center into an environmentally friendly data center is not a simple task, as many data center providers know. However, environmental sustainability is not only consistent with various regulatory norms, but also to ensure the sustainability of its own business.

The US Department of energy Laurence Berkeley National Laboratory released a report in 2016. It estimated that the data center accounted for nearly 2% of the total energy consumption in the United States, though the number is not surprising. But with the development of cloud computing, the number of data centers will only increase. That means more energy emissions. Data center providers must reduce carbon emissions from data centers and develop as much as possible to the green data center.
How to go to the green data center:
1. using a variable frequency driver: a variable frequency driver (VFD) is a device installed on a air-cooled chiller to improve efficiency. It helps to reduce the speed of the cooler in the non peak time, thus reducing the energy consumption.
2. follow the heat guide: the American heat, refrigeration and air conditioning engineer Society (ASHRAE) has issued a number of heat guides when setting up a data center. Many of the key points are to optimize the internal equipment to achieve the best use of resources, including reducing the cooling power.
3. use channel containment: This is a technology to prevent the mixture of cold air from the supply side of the data center and the hot air on the exhaust side. It involves the use of physical barriers and significantly improves the cooling efficiency.
4., Virtualization: virtual servers are a good substitute, because they help reduce the number of physical servers, thereby saving space, cost and energy usage. Using this method, multiple server instances can be allowed to run on a single machine, thereby reducing energy output immediately.
5. upgrading personal computers: the latest products in the PC market, which provide environment-friendly models, such as "thin client computers", will not use electricity as traditional computers do.
6. use the rack blanking panel: these panels are used to create the contained rack environment. They basically eliminate the gap in the server rack, thus improving the capacity of the cooling unit, thus improving the cooling efficiency.
7. control cooling: it is a good idea to track the cooling requirements according to the external weather. For example, on cool days, close some coolers and compressors and rely on outside air conditioning to effectively reduce the temperature of the data center.
Using these means is just the first step towards the green data center. Now many data center providers or cloud providers are trying to promote the progress of green data center, including many technological innovations.
