According to a report submitted to the U.S. Congress by the U.S. Environmental Protection Agency, in the data center, the total power consumption, refrigeration accounted for about 40%. The IDC study also showed that in the data center cooling operation more power than the server itself, when the server increases exponentially, supporting the use of electricity will be exponential rise. IDC has done a survey, the average annual power consumption of 100 servers for each of the 550 thousand degrees, which is used for the cooling of electricity for the server power consumption of 2.7 times.
The data center is usually used for centralized processing of local information, computer equipment, network equipment, storage equipment, communication equipment is the key equipment in processing information essential to the IT, for the energy saving of these devices is a natural requirement. However, for those who used to protect the IT infrastructure operation of key equipment, such as UPS, air conditioning, people often do not pay attention to, but also large power consumption of these devices, among which the power consumption of the refrigeration.
It should be said that the cooling is not the beginning of the data center in the power of the large, but with the popularity of computer applications and make this problem increasingly prominent. In the past, due to the application of computer is not popular, the data center of the IT key equipment is not much room space is relatively well-off, there are few local hot spots in the cabinet. Therefore, some data centers, even if the use of ordinary air conditioning for the refrigeration room, but also to meet the requirements of the computer room. Most of the time as long as the temperature in the room to ensure the normal operation of the equipment, the equipment can also be normal operation.
Now, with the popularity of IT technology, the demand for IT equipment showing the explosive growth of the room is crowded, the last room spacious cabinet has been greatly small crowds, at the same time, the number of servers and switches in the cabinet also greatly increased, the whole room temperature and temperature in the cabinet are increased rapidly. In particular, the blade server in recent years is further aggravated the seriousness of this problem. On the blade server itself, it reduces maintenance costs, and land, energy saving, but the blade server has led to rapid increase in the density of the cabinet, so that the increasingly prominent cooling problems. Thus, in a number of data centers, although the room temperature has dropped to more than and 10 degrees, while the cabinet is still in the embarrassing situation of temperature alarm.
It is precisely because of this reason, in the increasingly valuable space in the room, the cabinet still have to vacate a lot of space. In fact, the refrigeration capacity of the cabinet has limited the number of blade servers installed in each cabinet.
