Server, power supply application method and control device

Abstract

The embodiment of the invention relates to the technical field of electronics, and discloses a server, a power supply application method and a control device. In the embodiment of the invention, the power supply application method comprises the following steps: detecting the number of power supplies of a working power supply in a system and reading a system power value; if it is detected that thenumber of the working power supplies is at least two, and an abnormal trigger signal is received from the logic trigger module, obtaining an early warning power value according to a plurality of system power values; and if the early warning power value is greater than or equal to the power supply power value of the working power supply, outputting an abnormal processing signal to a control modulein the server through the logic trigger module, so that the control module reduces the processor power to a preset value and limits the system power to be within the maximum power of the working powersupply. According to the embodiment of the invention, under the condition that the system has a redundant power supply function, the cost is saved, the power supply utilization rate and the conversion efficiency are improved, the condition that the system oscillates can be avoided, and the purpose of safe use is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular to a server, a power supply application method, and a control device. Background technique [0002] In the field of server redundant power supply applications, in order to meet the redundant design, it is necessary to consider that when there is only one power supply, the maximum configuration that can be covered, the maximum temperature, and the maximum pressure for all software to run. A certain margin is required to ensure power supply; for example, the maximum power consumption under the maximum load of the current system is 650W, and several power supplies with redundant functions in the existing solution, for example, two power supplies must be at least 650W each. [0003] However, the inventors have found that the prior art has at least the following problems: (1) the redundant design of the existing solution leads to low utilization rate of a si...

Problems solved by technology

[0003] However, the inventors have found that the prior art has at least the following problems: (1) the redundant design of the existing solution leads to low utilization rate of a single power supply (about 10%-30%) in the actual application environment, and the conversion efficiency relatively poor

(2) In the existing redundant design scheme, when the system is over-powered, if one of the power supplies is powered off, the system will crash

(3) If the system power is limited to be lower than the power of one power supply, the system cannot perform at its maximum performance
