Description
Technical field
The present invention relates to server technology field, more particularly, to a kind of control method for fan of server, device and service
Device.
Background technology
At present, by the entity temperature sensor of arrangement in the middle part of server, can read a limited number of feature in server
The temperature information of part, for example, CPU（Central Processing Unit, central processing unit）、PCH（(Platform
Controller Hub, platform courses center) etc..Entity temperature sensor is read by server heat management control strategy
Temperature information as the control parameter to fan in server and feature power consumption, by improving or reducing the rotating speed of fan
Or within the power consumption of controlling feature part is to ensure the restriction scope that the temperature of the feature in server designs at it.This
Outward, because the feature of heating in server runs far deeper than the crucial feature such as CPU or PCH, therefore also can be suitable
Ground improves the rotating speed of fan further that is to say, that by keeping certain air quantity redundancy in server, to ensure that server dissipates
The security of the effect server of heat.
But the problem that presently, there are is, 1）, the temperature information of all features cannot be grabbed, for example, hard disk, interior
Deposit.And to keeping certain air quantity redundancy in server, be only based on the experience of designer, and can be pre- according to some
Survey conventional scene this amount of redundancy to formulate.If the less words of amount of redundancy can lead to server overheated, if amount of redundancy is larger
If can cause the waste of fan power consumption.Therefore, the reliability of the server real time temperature data reading is very poor, leads to clothes
In business device, the rotating speed of fan can not accurately be controlled.For example for some storage-type servers, CPU in many cases
Duty factor lighter, therefore the temperature of CPU is also than relatively low.But hard disk is larger due to read-write data volume ratio, leads to the work(of hard disk
Consumption is very big, temperature is very high.Now iff the temperature information with reference to CPU, it is mistakenly considered server and is in idle condition, from
And make server controls fan work under the very low pattern of rotating speed, there is the overheated risk of hard disk.That is, due to no
Method reads the temperature information of hard disk it is therefore necessary to lift the minimum rotation speed of the fan under server free state, to solve hard disk
The too high situation of temperature.If but when actually server is truly under idle condition, the rotating speed of fan does not need so
Height, will necessarily cause the waste of fan power consumption.
2）, due to the feature in server temperature information also be subject to environment temperature, system wind flow, heating during
Many factors such as power consumption affect, therefore, it is difficult to grab enough, sufficiently accurate temperature information, and also are difficult to
To accurate wind flow information, therefore in the server of prediction, the reliability of real time temperature is also very poor, necessarily can not reach to wind
The purpose of fan precise control.
