Problems solved by technology

However, the short-term CPU overclocking technology will also increase the power consumption of the system. In some severe cases, the overclocking of the CPU may cause the overcurrent protection of the power supply and cause the entire system to be powered off, and the user's application will be interrupted.
It is the emergence of this situation that greatly reduces the reliability of the server, and the user application is not safe enough

Embodiment Construction

[0017] A method of a server power supply protection system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] as attached figure 1 As shown, the method for protecting a server power supply includes a server power supply and a CPU. A current detection circuit and a fast alarm circuit are set inside the server power supply. A buffer capacitor is provided between the server power supply and the CPU. figure 2 As shown, the specific system protection steps are:

[0019] 1) Calculate the maximum current load of the power supply through the estimated maximum power consumption of the system, and then calculate the current value threshold according to the actual overload capacity of the power supply;

[0020] 2) The internal current detection circuit of the power supply detects the current current value in real time;

[0021] 3) When the current current value is less than the current threshold, the power supply works no...

Abstract

The invention provides a method of a server power supply protecting system, and belongs to a computer server technique. The server power supply protecting system comprises a server power supply and a CPU (central processing unit), wherein the inside of the server power supply is provided with a current detection circuit and a quick alarming circuit, and a buffer capacitor is arranged between the server power supply and the CPU. The method comprises the following specific system protecting step of preventing the overload faults of the power supply through the current detection of the power supply and the prejudging of a CPU frequency modulation mechanism. Compared with the prior art, the method of the server power supply protecting system has the advantages that the reliability of the server is effectively improved, and the application safety of a user is ensured.

Description

technical field [0001] The invention relates to the technical field of computer server applications, in particular to a method for protecting a system through current detection of a power supply and a CPU frequency modulation mechanism. Background technique [0002] Today's server products usually use short-term CPU overclocking technology (turboboost) to complete task processing when faced with short-term high load conditions. In this way, the cost of purchasing high-frequency processing is saved for users, and better product cost performance is achieved. However, short-term CPU overclocking technology will also increase system power consumption. In some severe cases, excessive CPU overclocking may cause power supply overcurrent protection, resulting in power failure of the entire system and interruption of user applications. It is the emergence of this situation that greatly reduces the reliability of the server, and the user application is not safe enough. Contents of ...
