As long as the unused servers are turned off, the energy savings can be quite amazing. You may think that every server in the data center is strictly managed, then you are wrong. If you do not turn off these unused servers, it will only consume more energy.
The Green Grid estimates that the average cost of power supply for a server is $ 250 a year. If a data center has 5,000 servers, and if 5% of the servers are idle, it will consume $ 62,500 in electrical energy. The conclusion of the green grid is: "Shut down unused servers to avoid the cost of a new data center. Even a small number of servers, but this is also an expensive problem. Can not be ignored!"
Optimization of data center cooling and airflow organization
Managing airflow and air pressure is a key step in the data center, which helps the data center improve energy efficiency. When you use air cooling, you need to make sure that the cold air reaches the server and takes away most of the heat. However, there are many places in the data center that "clogged" the circulation and recirculation of airflow. If the lower air supply and the lower wiring are used, the height of the raised floor is too low or the cables are too many or the cables are messy. The poor air supply leads to insufficient air supply at the air outlet; the distance between the top of the cabinet and the ceiling is too short, resulting in air circulation ; Too many servers are placed in the cabinet, the density is too large, the heat dissipation is large, and the cold wind cannot take away too much heat. In response to many problems, in order to prevent the generation of high heat density in the data center and improve the energy efficiency of the data center, we recommend:
Reasonable wiring. It is best to use the upper wiring method. In addition, the structured wiring system can eliminate confusion and redundant cables. Cutting the cables and connecting the power supply to the correct length can provide more space for air flow.
Strengthen the air supply. If using floor ADU or cabinet ADU. For more information, refer to: ADU Smart Solution for Cabinet Air Distribution Unit.
Processor and server
The growth of electricity is the main factor that promotes the operation of data centers and will make their facilities more energy efficient. Although the power company's spending has soared, it is still not the largest proportion of data center costs. According to research by Amazon James Hamilton, the cost of electricity consumed by server hardware in data centers accounts for about 57%.
Therefore, server procurement is one of the most important factors to make the data center more cost-effective and energy efficient. Chip manufacturers Intel and AMD have made significant progress in improving the energy efficiency of processors. New manufacturers are initially building low-energy processors for mobile devices, including Intel ’s Atom and ARM chips that support the iPhone. This has a major impact on server updates. Although the economic downturn has caused difficulty in capital expenditures, the capabilities provided by newer servers can simultaneously provide power and reduce the use of energy, making them easier to invest in.
