Regulate and control rotation speed of the fan.
If the minimum value is greater than the threshold value, rotation speed of the fan is not regulated and controled；If the minimum value is less than or equal to
The threshold value then controls reduction rotation speed of the fan.When reducing rotation speed of the fan, while controlling CPU frequency reducing.
As shown in Fig. 2, before the step in embodiment 1 is added to current fan regulation and controlling strategy, i.e., in existing fan regulation and controlling
On the basis of strategy, the regulating strategy of embodiment 1 is added.
After the regulating strategy of embodiment 1 is added, the detailed process of fan regulation and controlling is carried out are as follows:
If the minimum value of disk read-write rate percentage is greater than given threshold, wind is carried out according to current fan speed-regulating strategy
Fan speed regulation；If the minimum value of disk read-write rate percentage is less than or equal to given threshold, in the base of current fan speed-regulating strategy
Rotation speed of the fan is reduced on plinth.Equally, when reducing rotation speed of the fan, while CPU frequency reducing is controlled.
As shown in Figure 3,4, the fan regulation and controlling system that the present invention avoids hard disk performance from decaying includes data obtaining module 1, deposits
Store up module 2 and analysis and Control module 3.
Data obtaining module 1 is used to obtain the current read-write rate of each hard disk；Memory module 2 is for storing each hard disk
Current read-write rate；Analysis and Control module 3 is used to be arranged the threshold value of disk read-write rate percentage, calculates each hard disk and currently reads
Writing speed percentage, and the minimum value of hard disk present rate percentage is compared with the threshold value, and according to comparison result,
Regulate and control rotation speed of the fan.
Data obtaining module 1 is storage testing tool IOmeter；Memory module 2 is the register being arranged on mainboard；Point
Analysis control module 3 is BMC, is connect with register by I2C bus, realizes the monitoring point to disk read-write rate in operating system
Analysis, while BMC passes through I2C bus marco rotation speed of the fan.
In regulation process, to avoid rotation speed of the fan is too low from leading to system radiating problem, once disk read-write rate percentage
The minimum value of ratio is lower than given threshold, and BMC sends commands to ME by I2C Channel Synchronous, and ME makes CPU frequency reducing.
The above is the preferred embodiment of the present invention, for those skilled in the art,
Without departing from the principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also regarded as this hair
