Abstract
The invention provides a device and a method for automatically controlling a fan during power-on of a server, which relate to the technical field of computer servers and comprise 5 parts, namely (1) a temperature acquisition module, (2) a fan control module, (3) a BMC management module, (4) a line switching module and (5) a fan module, wherein a BMC management chip monitors and controls a heat dissipation system before initialization is finished immediately after AC power-on of the server, and meanwhile, two circuits can be automatically switched to control the rotating speed of the fan, so that the reliability of heat dissipation of the system can be ensured, and the consumption of extra power caused by fixing high rotating speed can be avoided.
Description
Technical field
The present invention relates to computer server technical field, particularly relate to a kind of server and power on and automatically control fan assembly and method.
Background technique
After system normal power-up, BMC managing chip needs a period of time to carry out initialization, generally this time tens seconds to a few minutes not etc.During this period of time the rotating speed of fan is not by the impact of cpu temperature, general heat dissipation design be exactly by the speed setting of fan to a maximum (top) speed, bring like this noise large and power consumption is high must problem.Or adopt and fix a rotating speed, have the risk of heat radiation like this.BMC management system is the system of a more complicated, may occur when BMC runs into fault the generation that BMC crashes, and occurs if BMC there will be the not controlled phenomenon of fan after crashing.So just can not ensure the normal operation of system.
Summary of the invention
In order to solve this problem, the present invention proposes a kind of server to power on and automatically control fan assembly, the present invention can server just AC power on after BMC managing chip do not have initialization to complete before monitor and forecast is carried out to radiation system, can automatically switch between two circuit simultaneously, complete the control to rotation speed of the fan.
A kind of server powers on and automatically controls fan assembly, comprise: temperature collect module, fan control module, BMC administration module, circuit switch module, fan module 5 parts, temperature collect module, fan control module, circuit switch module, fan module composition circuit 1, BMC administration module, circuit switch module, fan module composition circuit 2
Wherein:
(1), temperature information for gathering the temperature value of CPU periphery and other high-power chips, and is delivered to next stage fan control module by temperature collect module;
(2), fan control module receives the temperature information of temperature collect module, calculated the air quantity of system needs, and the control signal of rotation speed of the fan is delivered to circuit next stage cable handover module by the temperature information comparing input;
(3), BMC administration module is the higher management of whole server, for the radiation system of system and the monitor and managment of power supply system; BMC obtains the temperature information of CPU by the temperature directly reading CPU; And export rotation speed of the fan control information to cable handover module;
(4), circuit switch module is responsible for circuit switched 1 and is controlled rotation speed of the fan or circuit 2 controls rotation speed of the fan; Meanwhile, cable handover module can judge whether BMC completes initial work, according to the condition selecting circuit of BMC;
(5), fan module is made up of more than one fan, and for system radiating provides air quantity, the size of air quantity is controlled by BMC administration module or controlled by fan control module, and fan control power is selected by circuit switch module.
First time powers on, and the priority of circuit 1, higher than circuit 2, gives tacit consent to the select line 1 when first time powers up.
Present invention also offers a kind of server to power on and automatically control the method for fan, by temperature collect module, fan control module, circuit switch module, fan module composition circuit 1; By BMC administration module, circuit switch module, fan module composition circuit 2,
After server powers up, circuit 1 commences work without delay, and circuit 2 is in init state; The temperature of the multiple temperature spotss gathered is compared analysis by temperature collect module, a temperature that working condition is the poorest is delivered to fan control module, because first time powers on, the priority of circuit 1 is higher than circuit 2, so circuit switch module select line 1 carries out rotation speed of the fan control; Can inform that circuit switch module carries out circuit switching after the initialization of BMC administration module completes; Rotary speed information through switching aft-fan module transfers to BMC administration module to control;
The cisco unity malfunction if BMC administration module breaks down, circuit switch module can detect dropout, gives circuit 1 immediately control fan control power;
If BMC can send switching signal to diverter circuit after restarting or automatically replying, fan control power transfers to BMC administration module to control by circuit switch module again.
The invention has the beneficial effects as follows.
The present invention can after at server, just AC powers on, managing chip carries out monitor and forecast to radiation system before not having initialization to complete, can ensure that the heat radiation of system effectively can control power consumption again, and effectively can reduce the large current drain that multiserver starts shooting simultaneously.The invention solves before BMC control chip normally works, radiation system can need automatically to control rotation speed of the fan according to heat radiation, and effectively avoid the heat radiation risk that employing fan attachment rotating speed brings, solve again fan maximum (top) speed and start the excessive current drain brought, simultaneously, the present invention is also the redundancy approach that radiation system rotation speed of the fan controls simultaneously, can ensure managing chip quit work after alternative managing chip control rotation speed of the fan, realize the auto-control of radiation system, realize the redundancy of radiation system.
Accompanying drawing explanation
Fig. 1 is work structuring schematic diagram of the present invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing the present invention being done and describing in detail further.
The present invention includes: (1) temperature collect module; (2) fan control module; (3) BMC administration module (4) circuit switch module; (5) fan module.Totally 5 parts, by temperature collect module, fan control module, circuit switch module, fan module composition circuit 1; By BMC administration module, circuit switch module, fan module composition circuit 2.
After server powers up, circuit 1 commences work without delay, and circuit 2 is in init state.The temperature of the multiple temperature spotss gathered is compared analysis by temperature collect module, a temperature that working condition is the poorest is delivered to fan control module, because first time powers on, the priority of circuit 1 is higher than circuit 2, so circuit switch module select line 1 carries out rotation speed of the fan control.Can inform that circuit switch module carries out circuit switching after the initialization of BMC administration module completes.Rotary speed information through switching aft-fan module transfers to BMC administration module to control.The cisco unity malfunction if BMC administration module breaks down, circuit switch module can detect dropout, gives circuit 1 immediately control fan control power.If BMC can send switching signal to diverter circuit after restarting or automatically replying.Fan control power transfers to BMC administration module to control by circuit switch module again.Ceaselessly repeating according to above mechanism, realize the redundancy of radiation system, also automatically control rotation speed of the fan when just starting to power on according to true temperature.
