Currently, China¡¯s data centers are in a period of rapid construction and have gradually penetrated into government, finance, telecommunications, the Internet, healthcare, military industry and many other sectors; future **ment will be even faster. How to build a data center with an autonomous and controllable, high-performance hardware platform of servers and storage and a complete cloud-computing and big-data application-software platform - to meet the ever-growing massive data volumes and the complex, changeable demands of emerging business applications, while effectively building an autonomous and controllable information-industry system and safeguarding national political and economic security - is currently a IThuge challenge facing the IT industry. Information security and information sovereignty are strategic as well as economic issues; autonomous and controllable cloud computing and big-data centers will become key infrastructure for the **ment of China¡¯s digital economy.

Data Center Temperature and Humidity
1Design of data center rooms and temperature/humidity environmental requirements
(1)Contaminants. Stay away from corrosive gases and flammable/explosive materials; corrosive gases drawn into the room with fresh air can harm computer equipment and personnel health, and unclean air can adversely affect the operation of computer equipment and also contaminate the filters of precision air conditioners and fresh-air units in the room.
(2)Temperature, Humidity
¡¡¡¡Temperature and humidity must be strictly controlled to provide a temperature and humidity range for continuous operation.
¡¡¡¡Dry-bulb temperature:20¡æ~25¡æ(68F~77F)¡£
¡¡¡¡Relative humidity:40%~**%¡£
¡¡¡¡Maximum dew point:15¡æ(59¨H)¡£
Minimum dew point: 5.5¡æ(41.9¨H)¡£
Maximum rate of change:per hour5¡æ(9¨H)¡£
(3)Noise. When the computer system is shut down, the noise in the room, measured at the center of the main equipment room, should be less than 65dB(A)¡£
(4)Illuminance. At a height of 0.8m above the floor, the illuminance should not be less than 300lx; auxiliary rooms should have an illuminance of no less than **lx¡£
(5)Radio interference field strength. At a frequency of 0.15~**0MHz, it should not exceed 126dB¡£
(6)Magnetic interference field strength should not exceed 800A/m¡£
(7)With the computer system shut down, the vertical and horizontal vibration acceleration of the main equipment room floor surface should not exceed 5OOmm/s¡£
(8)The electrostatic leakage resistance of the main room floor and work surfaces should comply with the current national standard GE66**-1986 "Technical Specifications for Raised Access Floors for Computer Rooms".
(9)The electrostatic potential of insulators in the main room should not exceed lkV¡£
2.Data Center Cooling
Cooling the heat sources of a data center directly is the most effective cooling method. Available technologies include immersion cooling and direct liquid-cooling systems, with the goal of safe heat dissipation using the minimum energy.
The cooling fans of the cooling system drive cool air under the raised floor and through the air ducts; installing cooling units close to the computer equipment effectively reduces the energy required by the fans. Which heat-source cooling method to choose depends on the building design, aisle accessibility, cost and other factors.
The circulating liquid - water or refrigerant - carries heat away from the cooling unit and out of the data center through pipes. Although water leakage in a data center is a serious concern, proper installation together with leak detection and drainage systems can reduce the risk of costly equipment damage. If you are still unwilling to let water flow through your data center, you can instead use a refrigerant that turns into a harmless gas immediately upon leakage. However, pipes carrying refrigerant are harder to install and ** expensive than water pipes, so the choice requires careful consideration.
¡¡¡¡Many heat-source cooling units remove only sensible heat - the heat that people can feel. The sensible heat produced by electronic equipment contains no moisture, so most heat-source cooling units do not have humidity control.
Because most heat-source cooling units cannot effectively handle scenarios with low heat loads, data centers dominated by low heat-density racks and cabinets still need conventional air conditioners, such as perimeter CRAC units. In other designs, separate humidity control may be a necessary complement to the heat-source cooling units.
