Server platform power consumption optimizing method and device

Abstract

The invention provides a server platform power consumption optimizing method and device. The method comprises: reading configuration type of a system; acquiring a correspondence table for corresponding CPU (central processing unit) usage and power consumption according to the configuration type of the system; reading a current stable value of CPU usage; setting an upper limit of power consumptionaccording to the value of the CPU usage; adjusting operating frequency of a CPU according to the upper limit of power consumption; monitoring whether the value of CPU usage is stable; if not, releasing the upper limit of power consumption that is already set; after the value of CPU usage is stable, resetting the upper limit of power consumption corresponding to the current value of CPU usage. Theserver platform power consumption optimizing method and device have the advantages that the upper limit of power consumption can be adjusted in real time at the premise of ensuring server performance,the power consumption of a server is dynamically optimized, and power consumption cost is reduced for the server.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a method and device for optimizing power consumption of the entire server platform. Background technique [0002] When deploying large numbers of server systems, the total amount of capital output, operational power consumption, and cooling costs due to server power consumption can be staggering. Most of the machines currently on the market use the method of setting the power consumption policy on the web management interface of the BMC (Baseboard Management Controller, baseboard management controller) to limit the power consumption. Strategy, pass the power consumption strategy to the ME (Management Engine, management engine) through the command of the node manager, and the ME will save the power consumption strategy. When the power consumption of the server is too high, the ME will adjust the operating frequency of the CPU. In order to achieve the purpose of limiting p...

Problems solved by technology

[0004] After the BMC web management interface is set up, the upper limit of power consumption is hard-coded. When the server pressure is very high or low, it will cause limitations on server performance.

In addition, under different usage conditions, server operation and maintenance personnel need to continuously adjust these power consumption values, which undoubtedly puts a certain amount of work pressure on the operation and maintenance personnel
