This application claims the priority of the Chinese Patent application filed on Sep. 5, 2022 before the China National Intellectual Property Administration with the application number of 202211077462.4, and the title of “SERVER POWER SUPPLYING METHOD AND SYSTEM, DEVICE, AND MEDIUM”, which is incorporated herein in its entirety by reference.
The present application relates to the technical field of servers and, more particularly, to a server power supplying method and system, a device, and a medium.
With the development of cloud computing applications, informatization has gradually permeated all sectors of society. People's daily work and life increasingly rely on the Internet for communication, resulting in a continuous increase in the volume of network data. For traditional data center rooms, in order to avoid the enormous investment required for rebuilding data centers and to meet the growing demand for information services, the requirements for servers are also increasing. People also require servers to operate continuously for 24 hours to satisfy the ever-growing business demands.
At the same time, in order to meet the growing market demand and cover different application scenarios, existing servers has been added numerous graphics processing unit (GPU) configurations. The power supplying methods for the GPU configurations have become a hot topic of discussion.
Currently, in order to meet different application scenarios, the server system has been added numerous models with the GPU configurations. Since most GPUs are powered by 54 V power supplies, while other system components, such as hard drives, peripheral component interconnect express (PCIe) devices, and motherboards, are powered based on 12 V power supplies. This necessitates the use of a 54 V output power supply unit (PSU) to supply power to the entire system, requiring the conversion of a 54 V voltage to a 12 V voltage at the system end for distribution to other components. In this process, certain conversion efficiency and conversion circuitry are existed, costs are increased, and power supplying efficiency is reduced. Accordingly, power consumption for the system is increased. In the related art, a significant disadvantage that the power supplying mode utilizes a 54 V power supply combined with a 12 V conversion module is that the efficiency (overall efficiency=54 V power supplying efficiency* 12 V conversion module efficiency) is low. Another significant disadvantage is that the 12 V conversion module is embedded within the system and is a part of the motherboard. If the conversion module is damaged, the system may be shut down and opened for maintenance, replacement is difficult and maintenance costs are high.
In view of this, a server power supplying method and system, a device, and a medium are provided by the present application. Two types of PSUs, which are 12 V and 54 V, are used to supply power to the server system, and a hybrid power supplying mode is used to improve the overall efficiency, the power supplying efficiency is equal to the individual efficiency of each PSU. Moreover, mechanical foolproof and electrical foolproof are also added in the whole power supplying solution, which prevents the problem of mixed insertion of 12 V power supply and 54 V power supply. In addition, the power-on sequence is also strictly controlled in the power supplying solution, that is, giving priority to 54 V output followed by 12 V output, to solve the voltage overshoot caused by the simultaneous power-on of the two power supplies, and realize the time-sharing power-on of the server system.
