Control method and system of server heat dissipating controller

Abstract

The invention provides a control method and system of a server heat dissipating controller. The heat dissipating controller comprises a control chip, a temperature sensor and a fan controller; the temperature sensor is connected with the input end of the control chip, and the fan controller and the control chip build communication connection through an independent link; and the control chip is connected with a BMC through an I2C. The method includes the steps that heat dissipation strategy data of updating of the BMC are acquired; server temperature measuring point temperature acquired by thetemperature sensor is acquired; according to the temperature and heat dissipating strategy data, a target rotating speed of fans is generated; and a current rotating speed of a fan corresponding to the temperature sensor is acquired, a rotating speed adjusting and control signal is generated according to the current rotating speed and the target rotating speed, and the rotating speed of the fans is adjusted and controlled. According to the control method and system of the server heat dissipating controller, heat dissipating control of a server is stripped away from the BMC, resources of the heat dissipating controller are sufficiently and effectively utilized, it is achieved the heat dissipating controller independently performs independent control over the various fans, and heat dissipating is accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of server heat dissipation, and in particular relates to a control method and system of a server heat dissipation controller. Background technique [0002] During the operation of the server, effectively controlling heat dissipation is the key to ensure the stable operation of the server. In the current server design, a BMC (Baseboard Management Controller, baseboard management controller) is generally used to manage the server mainboard. The BMC can monitor the health information of the mainboard, realize the detection of power consumption, temperature and fan speed, and control the mainboard fan. [0003] In current server applications, people have higher and higher requirements for servers in terms of environmental protection, quietness, power consumption, and stability. At present, the existing BMC heat dissipation control is increasingly unable to meet the requirements of environmental protection, quie...

AI Technical Summary

Problems solved by technology

[0006] 2. BMC functions are becoming more and more abundant, the system is becoming more and more complex, and more and more resources are occupied. When performing certain tasks, the resource expenditure is relatively large, and the impact on the timely regulation of heat dissipation is increasing.

Affect the timeliness of cooling adjustment

[0007] 3. Now the server business is becoming more and more complex, especially high-density servers and AI servers consume a lot of energy, have a lot of power and heat, and have limited space, making it difficult to dissipate heat. The sudden increase in business causes the temperature to rise sharply in an instant, causing serious problems

[0008] 4. Most of the multi-fan control of the server in the existing scheme is unified control, without decentralized individual control

Unable to precisely control, resulting in a certain waste of resources, not environmentally friendly and energy-saving

[0009] 5. When the server is controlled by a single BMC, the BMC fails due to BMC firmware update failure, attack, etc., and the heat dissipation of the entire server will be in a paralyzed state, causing customer business interruption, and even equipment burnout.

When the server adopts the design of technical solution 3 and adds a controller, the controller is idle in most cases and needs to communicate with the BMC repeatedly, so the resources of the controller cannot be fully utilized

It will also increase the burden on the BMC
