The basic measure system of IDC data center mainly includes power supply, environmental control and computer room monitoring and management system. Because IDC data center bears the core business of enterprises and institutions, it is of high importance. Therefore, IDC data centers are generally built according to the Tier4 and Tier3 standards of TIA942, with reliability requirements of more than 99.999%, to ensure that the data center can work normally and the core business will not be affected in the case of abnormal failures and normal maintenance in most departments.
1. The power supply system usually selects multiple municipal power supplies as backup for each other, and the machine room is equipped with a dedicated diesel generator system as the backup power supply system. The municipal power supply room, the municipal power supply room and the diesel generator room are switched through ATS (automatic transfer switch UPS (without interrupting the power supply), air conditioning in the machine room, lighting and other equipment.
Because of the importance of IDC data center business, the power supply scheme of dual bus or redundant parallel is usually adopted to meet the requirements of medium-sized data centers The server And other IT equipment high reliability power requirements. The dual bus power supply system has two independent UPS power supply systems (including UPS power distribution system). In the event that any power supply bus (power supply system) needs maintenance or fails to supply power normally, the other power supply bus can still bear all loads, so as to ensure the power supply of the computer room business and ensure that the data central business is not affected. Redundant parallel power supply system adopts UPS redundant parallel power supply to improve the reliability of power supply system and ensure the power supply of data center.
The output is sent to the input room of IT equipment such as servers, and SPM (Server Power Manager) is selected for power distribution and power supply management, so as to realize the power monitoring and management of each cabinet and improve the reliability and ease of governance of the power supply system. For IT equipment such as servers with dual power supply, the power supply can be directly attracted from the two buses of the dual bus power supply system through SPM, which can ensure its high reliability of power consumption. For IT equipment such as servers with single power supply, STS (static switch) is usually selected to switch a set of power supply bus for power supply. When the power supply bus fails to supply power normally, STS will automatically and quickly switch to another bus with normal power supply to ensure reliable power consumption of IT equipment such as servers.
