Server power supply current sharing method, system and device and medium

Abstract

The invention discloses a server power supply current sharing method, system and device and a storage medium, and the method comprises the steps: employing a first number of first power supplies withfirst reference power and a second number of second power supplies with second reference power to supply power to a server, and connecting the first power supplies and the second power supplies; calculating an average current value of all power supplies based on the total load power, enabling the current value in each power supply to be the average current value, and obtaining an output voltage value corresponding to each power supply based on the average current value; in response to the change of the total load power, calculating a new output voltage value corresponding to each power supplyand judging whether the new output voltage value exceeds a preset threshold value or not; and in response to the fact that the new output voltage value does not exceed the preset threshold, adjustingthe output voltage value of the power supply to the new output voltage value. Isolation of power channels is eliminated, current sharing can be achieved for power sources with different reference powers, it can be guaranteed that protection cannot be triggered by small power, and the performance of the power sources is greatly improved.

Description

technical field [0001] The present invention relates to the field of servers, and more specifically, to a method, system, computer equipment and readable medium for current equalization of server power supplies. Background technique [0002] LinkedIn OPEN19 proposed a set of open server standards, with the goal of increasing the density of 19-inch (now mainstream server standard size) data center rack servers and storage, as well as network-related equipment, reducing the cost of rack equipment, and optimizing rack integration and deployment , optimize power utilization, and ultimately provide low-cost infrastructure solutions for data centers in different environments. [0003] Since the power shelf is generic, any power source, AC, DC, single phase or multi-phase, everything is fed to the power shelf and distributed to the system, so the servers have no idea of ​​their environment. Open19 uses decentralized hardware with complete power isolation between servers. There ar...

Problems solved by technology

Because the e-fuse in the Power Shelf has a limit of 35A, 1 group is 400W, and a maximum of 4 groups of eFuses in parallel can output 1600W. Because the current server power density is getting higher and higher, and GPU applications are increasing in recent years, the short-term peak value of GPU The power demand characteristics are undoubtedly a big challenge for the current OPEN19. The application of 1600W is completely insufficient, and additional methods are needed to meet the needs.
