Hold energy HTA in data Center brings change to enterprise

November 16 Beijing report (text/seaweed) Even without cloud computing, companies are also trying to bring data together to provide better security and management, and with the advent of cloud computing, global companies are accelerating the size and speed of data centers, but as data centers grow in size and density, Energy consumption has begun to plague its development, in which the energy consumption of data centers is largely the result of cooling systems, and what will happen to our data centers if we allow the temperature of the data center to rise and reduce the energy consumption of the cooling system?

Last year, Intel launched the Open Data Center Alliance, which, after a year of development, grew stronger, in a series of http://www.aliyun.com/zixun/aggregation/9764.html "> Development directions for data centers, Intel has presented the HTA Data Center, an HTA is the abbreviation for high ambient temperatures, the Chinese literal translation is the higher ambient temperature, Intel hopes to reduce the energy consumption of cooling system, by increasing the temperature of the data center, to maximize energy conservation, and to improve the pue of the overall data center, we will be concerned about whether the HTA data center is necessary, and whether the HTA data center can actually be implemented.

Energy conflict

In discussing energy issues, we naturally have to focus on the energy situation of the data centres.

Today, 1.5% of the world's electricity generation is being supplied to data centers around the globe, not to be underestimated by 1.5%, which is equivalent to a year's worth of 50 large power plants, and the problem is not just energy consumption. Because of the huge demand for electricity in the data centers, carbon dioxide emissions are as high as 2.1 billion tonnes a year, the equivalent of 41 million vehicles.

What is the concept of a data center cooling system that consumes a large amount of water, and a global data center consumes 300 billion litres of water a year? If we put the water in the pool of the standard Olympic swimming games, we would need 25,000 swimming pools to install it.

The damage is far from over, because the data center needs a large number of air-conditioning equipment, these devices generally contain freon, it is known that this is the killer of the ozone Layer, and the destruction of the ozone layer will lead to a series of ecological disasters.

Even if companies do not care about these ecological problems, they should be concerned about their wallets, and the global data center spends 27 billion of billions of dollars a year on cooling systems as a result of the massive cooling.

We can see that in the existing data center, a large number of electrical energy is consumed by the cooling system, but at the same time, the current data center requirements of the operating temperature is generally 21 degrees Celsius, in order to ensure such a temperature, while in order to avoid the presence of local hotspots affect the server and storage reliability, Data centers have to adopt a large number of cooling equipment, which is a contradiction of energy supply, how to deal with enterprises?

Increase the ambient temperature

If our server can guarantee sufficient stability and reliability at temperatures above 21 degrees, can we properly improve the temperature of the data center to reduce the energy consumption on the cooling system and improve the pue of the data center?

As we can see, 77% of the world's data centers are currently working at 18-21-degree ambient temperatures, and if we raise the ambient temperature to 25-27 degrees, servers and storage can still work, but with huge energy savings.

The Earth's average temperature is 14 degrees, but the distribution is divided into imbalances, for many parts of the world, outdoor ambient temperature can be kept below 27 degrees, if we increase the temperature of the data center to 27 degrees, or even more than 30 degrees, then we no longer need air-conditioning, only natural wind cooling is enough, This will undoubtedly greatly reduce costs and pue.
