Today's competitive market, all the challenges are brought together in the data center. Large-scale data center hosting business, the Group, the agency's core business, the importance of high, does not allow business interruption. IT density
Rising beyond the traditional power and cooling technology facilities; Secondly, the data center repeatedly changing business climate requires special flexibility to keep pace with the energy consumption and the need
Continuously enhance the data center has become the focus, energy efficiency is now a global problem.
Large-scale data center infrastructure system mainly consists of power, environmental control and room monitoring management system. Thus in large data centers is generally based on the standard construction of TIA942 standard Tier4 reliability requirements
99.99999% or more, in order to guarantee that the abnormal failure and normal maintenance cases, the data center to work properly, the core business is not affected.
Large databases
1, the power system is usually used multiple city power backup for each other, and the engine room has a dedicated diesel generator system as standby power systems, utility power through the mains power supply and diesel generators
ATS (automatic switch) to switch data center UPS (uninterruptible power supply), room air-conditioning, lighting and other equipment powered. Because of the importance of large-scale data center business, usually using double
Busbar power supply, power supply solutions to meet the high reliability of the electricity requirements of large data center servers and other IT equipment. Dual-bus power system, there are two sets of independent UPS power supply system (including UPS distribution system),
Any of a situation the supply busbar (power supply system) need maintenance or failure can not be normal power supply, and another set of power supply the busbar can still bear all the load to ensure the supply of engine room business, to ensure that the data center industry
Service will not be affected. UPS output to the input between the servers and other IT equipment, power distribution and supply management selection the SPM (server power management), each cabinet electricity monitoring and management, improve
The power supply system reliability and manageability.
2, environmental control systems, usually chosen room precision air conditioning adjust the data center environment, to ensure that the operating environment of servers and other IT equipment. Servers and other IT equipment for the large amount of heat, usually chosen
Qualcomm porosity (generally greater than 70%) Mesh Door Cabinet to improve the amount of cabinet and out of the wind; the cabinet face-to-face, back-to-back arrangement formed in the engine room, hot and cold air duct isolation, improve the cooling efficiency; air conditioning
Downflow way to ensure even blast the engine room, and improve the cooling efficiency.
Occasions in some of the power density is particularly high (heat than 5kw / cabinet), often prone to local hot spots, the formation of hidden faults. High heat density solution for the elimination of the local hot spots,
Case, such as an open program that is installed in the local hot spots occur at the refrigeration terminals XD strengthen local cooling capacity to eliminate localized hot spots; closed the program is the high power density of the device is placed in a closed cabinet
, Through the refrigeration cycle in the enclosure, the high-efficiency cooler.
3, room monitoring management system, large-scale data center needs power, air conditioning and other equipment running state management, also on the environment, such as temperature and humidity, water leakage, smoke and other parameters of the engine room
Monitoring to ensure that the data center within a normal range. And data center equipment operating parameters and environment the amount of real-time monitoring and management, remote monitoring and management, nobody value of the engine room
