Method for dynamically adjusting power supply efficiency in cloud computing industry by means of centralization

Abstract

The invention provides a method for dynamically adjusting power supply efficiency in the cloud computing industry by means of centralization. System hardware includes a power module, a primary power back panel, a node middle board, a secondary power panel, a management back panel and a fan plugboard, the primary power back panel is connected with the node middle board through a power line, the management back panel is plugged together with management mainboards and connected between the primary power back panel and the node middle board, and the management mainboards are simultaneously connected with computing nodes through a management network switch for transmitting electricity load conditions and are used for detecting a system consisting of the computing nodes and the node middle board through the management network switch for an IPMB (intelligent platform management bus). When the system is in a light-load environment, one of four power modules is closed by the aid of GPIO (general purpose input / output) signals or one power module is led to sleep by means of PMBUS (power management bus) commands, the other three power modules remain being used for outputting 12V power, the load factor of each power module is increased by one third than that of a prior power module at the time, and power sources are operated between a more efficient load interval, so that power is saved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for centralized and dynamic adjustment of power supply efficiency in the cloud computing industry. Background technique [0002] With the development of cloud computing, the number and scale of servers will increase linearly. Under the advocacy of low-carbon, environmental protection, and energy-saving concepts in today's society, cloud computing data centers have undoubtedly become a major power consumer. With the continuous development of power supply technology in the industry, the highest power supply efficiency today has reached the platinum level (94% conversion efficiency), which has basically reached the highest level in the industry. It is difficult to improve the efficiency of a single power supply to achieve energy conservation and environmental protection. In the next step, how to further reduce power consumption in the field of data centers to achie...
