[0004] However, since the working efficiency of the PSU will change with the change of the workload, for example, when the workload in the server is small, if all the PSUs share the load at the same time, the working efficiency of each PSU will be relatively low

specific Embodiment approach

[0077] In order to obtain the second output current threshold of the corresponding PSU according to the determined second loading threshold, and then lay a foundation for controlling the PSU to be turned on or off, the specific implementation of step 103 includes:

[0078]

[0079] Wherein, M represents the second output current threshold; p represents the rated power of the PSU; u represents the constant output voltage value of the PSU; S represents the second loading threshold.

[0080] The relationship between the working efficiency of the PSU and the loading threshold can be similar to a downward parabola, which can be specifically described as that as the loading of the PSU increases, the working efficiency of the PSU first rises and then decreases. Wherein, when the loading threshold is 50%, The PSU has the highest working efficiency and the most energy-saving, which is the most ideal working state. However, considering the actual working conditions, and in order to av...

Abstract

The invention provides a server power supply unit (PSU) state control method, an RMC and a cabinet. The method includes the steps that a first load threshold value and a second load threshold value of each PSU are determined; a first output current threshold value, corresponding to the first load threshold value, of each PSU is determined; a second output current threshold value, corresponding to the second load threshold value, of each PSU is determined, wherein the first load threshold value is smaller than the second load threshold value. The method further includes the steps that the current output current value of an arbitrary load PSU is detected; when the current output current value is smaller than the first output current threshold value, the arbitrary load PSU is controlled to be switched off; when the current output current value is larger than the second output current threshold value, the arbitrary load PSU is controlled to be switched on. The server PSUs can work with high efficiency.

Description

technical field [0001] The invention relates to the server field, in particular to a server power supply PSU state control method, RMC and cabinet. Background technique [0002] Nowadays, in order to reduce energy consumption, servers using PSU (Power Supply Unit, power supply) centralized power supply are more and more popular among users, and the higher the working efficiency of the PSU, the more energy-saving. [0003] Currently, when powering centrally, 2N PSUs will always work no matter how many workloads there are. [0004] However, since the working efficiency of the PSU will change with the change of the workload, for example, when the workload in the server is small, if all the PSUs share the load at the same time, the working efficiency of each PSU will be relatively low. Contents of the invention [0005] The embodiment of the present invention provides a server power supply PSU state control method, RMC and cabinet, which can make the server power supply PSU w...
