Large Data Center SmartSolution Solution
The infrastructure systems of large data centers are mainly divided into power supply, environmental control and computer room monitoring and management systems. Because large data centers carry the core business of enterprises, groups, and organizations, they are of high importance and do not allow business interruption. Therefore, the large data center is generally built according to the Tier4 standard of the TIA942 standard, and the reliability requirement is 99.99999% or more, so as to ensure the normal operation of the data center and the core business are not affected under abnormal faults and normal maintenance.
1. Power system, usually use multi-channel power supply for backup, and the machine room has a dedicated diesel generator system as the backup power system. The mains power supply, the mains power supply and the diesel generator are connected by ATS (automatic switch). Switch to supply power for UPS (uninterruptible power supply), computer room air conditioner, lighting and other equipment in the data center. Due to the importance of large-scale data center services, it is usually powered by a dual-bus power supply scheme to meet the high-reliability power requirements of IT equipment such as large data center servers. Double busbar power supply system, there are two independent UPS power supply systems (including UPS power distribution system). In case one of the power supply busbars (power supply system) needs maintenance or fault, etc., the other power supply busbar can still bear all the power. The load ensures the power supply of the equipment room and ensures that the data center business is not affected. SPM (Server Power Manager) is used for power distribution and power supply management between the UPS output and the IT equipment input such as the server. The power monitoring and management of each cabinet is realized to improve the reliability and manageability of the power supply system.
For IT equipment such as servers with dual power supplies, SPM can directly introduce power from two sets of busbars of the dual busbar power supply system to ensure high reliability. For IT equipment such as servers with single-channel power supplies, STS (Static Switching Switch) is usually used to switch one power supply bus. When the power supply bus is unable to supply power normally, the STS will automatically switch to another normal power supply bus to ensure reliable power consumption of IT equipment such as servers.
2, the environmental control system, usually select the computer room precision air conditioning to adjust the environment of the data center to ensure the operating environment of IT equipment such as servers. For IT equipment such as servers with large heat generation, cabinets with high-through-hole ratio (generally greater than 70%) mesh door are usually used to increase the air volume of the cabinet. The cabinets are placed face-to-face and back-to-back, forming a cold and heat-isolated air duct in the equipment room. Improve the cooling efficiency; the air conditioner adopts the lower air supply mode to ensure uniform air supply in the engine room and improve the cooling efficiency.
In some occasions where the power density is particularly high (heating capacity exceeds 5kw/cabinet), local hot spots are often generated, which may cause hidden troubles. In order to eliminate local hot spots, a corresponding high heat density solution is needed. For example, an open solution is to install a cooling terminal XD at the local hot spot, and strengthen the local cooling capacity to eliminate local hot spots; the closed solution is a high power density device. Placed in a closed cabinet, through the refrigeration cycle inside the cabinet, high efficiency cooling and heat dissipation.
3, computer room monitoring and management system, large data center needs to manage the operation status of power supply, air conditioning and other equipment, but also need to monitor the environment inside the equipment room, such as temperature and humidity, water leakage, smoke and other parameters to ensure that the data center works in a normal Within the scope of. Real-time monitoring and management of data center equipment operating parameters and environmental quantities, while remote monitoring and management, to achieve unattended operation of the equipment room.
