According to an aspect of the present invention, an embodiment of the present invention proposes a bandwidth control method, as shown in fig. 1, which may include the steps of: s1, acquiring the temperature of the hard disk; s2, judging whether the temperature is between a first threshold value and a second threshold value; s3, in response to the temperature being between the first threshold and the second threshold, reducing the value of the register of the hard disk from a default maximum value to a preset value; s4, determining the bandwidth reduction ratio based on the current value of the register of the hard disk; s5, calculating the difference value of the bandwidth reduction ratio and the target reduction ratio corresponding to the temperature; s6, according to the difference value, reducing the current value of the register by the value corresponding to the difference value, and returning to the step of determining the bandwidth reduction ratio until the bandwidth reduction ratio reaches the target reduction ratio.
The method disclosed by the invention can effectively control the read-write bandwidth of the solid state disk, thereby controlling the temperature rising speed. And the read-write bandwidth of the solid state disk is reduced by reasonably setting the value of the decrement and gradually reducing the value of the register in a grading way. Meanwhile, the speed and the accuracy of reducing the bandwidth can be considered.
Specifically, the method disclosed by the invention is that when the temperature of the hard disk is lower than a threshold value T, the value of a register R is kept at a default maximum value, and the bandwidth is also maximum at the moment; when the temperature of the solid state disk rises to a certain threshold value T, the value of the register R is reduced to an empirical value, the reduction ratio of the theoretical bandwidth is larger than the target reduction ratio D2 under the empirical value, the empirical value can be the maximum value meeting the conditions obtained after testing various fio models, then a timer is started, the timer is started at regular intervals T, the current reduction ratio is firstly calculated in the timer, and if the current reduction ratio is larger than the target reduction ratio D1, S2 is subtracted from the value of the register R; if the current reduction ratio is larger than the target reduction ratio by D0, subtracting S1 from the value of the register R; if the current drop ratio is larger than the target drop ratio, subtracting S0 from the value of the register R until the current drop ratio reaches or is lower than the target drop ratio, closing the timer and ending the flow of controlling the bandwidth; when the temperature of the solid state disk is lower than a threshold value T0 and temperature control is triggered, the value of the register R is restored to the default maximum value, and the bandwidth is also maximum at the moment.
For example, when the temperature of the solid state disk rises to a certain threshold, the FPMPA value is reduced to an empirical value, the reduction ratio of the theoretical bandwidth is 15 to 25 larger than the target reduction ratio under the empirical value, then a timer is started, the timer is started at regular intervals, for example, 1S, the current reduction ratio is firstly calculated in the timer, and if the current reduction ratio is more than the target reduction ratio, a larger decrement is subtracted from the FPMPA value; if the current reduction ratio is larger than the target reduction ratio, subtracting a smaller subtraction number from the FPMPA value; if the current drop ratio is smaller than the target drop ratio, subtracting a smaller subtraction number from the FPMPA value until the current drop ratio reaches or is lower than the target drop ratio, closing the timer and ending the flow of controlling the bandwidth; and when the temperature of the solid state disk is lower than a certain threshold value and temperature control is triggered, the FPMPA value is recovered to a default maximum value, and the bandwidth is also maximum at the moment.
In some embodiments, in step S3, in response to the temperature being between the first threshold and the second threshold, decreasing the value of the register of the hard disk from a default maximum value to a preset value, the method may further include:
in response to the temperature being greater than a first threshold and less than a fourth threshold, reducing the value of the register of the hard disk from a default maximum value to a first preset value;
and in response to the temperature being greater than a fourth threshold and less than the second threshold, reducing the value of the register of the hard disk from a default maximum value to a second preset value, wherein the second preset value is less than the first preset value.
Specifically, there are two temperature thresholds that trigger temperature control and start controlling bandwidth: t1 and T2, the temperature threshold for exiting temperature control is T0. When the temperature is T1-T2, the bandwidth is reduced to the previous rate1, and when the temperature is the highest temperature allowed by T2-nand, the bandwidth is reduced to the previous rate2, and the maximum bandwidth is recovered when T0.
The relationship between the above values is as follows, 100> rate1> rate2>0, 0< T0< T1< T2< nand allows the maximum temperature, wherein the maximum temperature allowed by nand is determined by the manufacturing process and technology of nand; 0< D0< D1< D2< 100-target reduction ratio; 0< S0< S1< S2<10, where 10 is also an empirical value after testing.
For example, there are two temperature thresholds that trigger temperature control and begin controlling bandwidth: the temperature thresholds for exiting temperature control were 68 ℃ and 75 ℃. When the temperature is between 70 ℃ and 75 ℃, the value of an FPMPA register is set as a first preset value, the reduction ratio of the bandwidth is larger than a target reduction ratio 1 by D2, when the temperature is between 75 ℃ and 83 ℃, the value of the register is set as a second preset value, and under the second preset value, the reduction ratio of the bandwidth is larger than the target reduction ratio 2 by D2.
In some embodiments, in response to the temperature being greater than the first threshold and less than the fourth threshold, decreasing the value of the register of the hard disk from a default maximum value to a first preset value, further comprising:
continuously acquiring the temperature of the hard disk;
in response to the temperature being greater than the fourth threshold and less than the second threshold, comparing the current value of the register with the second preset value;
and reducing the current value of the register to a second preset value in response to the current value of the register being larger than the second preset value.
Specifically, if the temperature interval does not experience the first threshold value to the fourth threshold value, but directly reaches the range between the fourth threshold value and the second threshold value, the value of the register is reduced from the default maximum value to the second preset value; if the target reduction rate1 is reached through the first bandwidth adjustment, the temperature continues to rise, and reaches a range between the fourth threshold and the second threshold, the current value of the register is compared with the second preset value, if the second preset value is small, the second preset value is set, otherwise, the register value is unchanged.
In some embodiments, step S4, determining the bandwidth reduction ratio based on the current value of the register of the hard disk, further includes:
obtaining the IO request number corresponding to the current numerical value and the initial IO request number corresponding to the default maximum value;
and determining a bandwidth reduction ratio according to the IO request number and the initial IO request number.
Specifically, the method can be implemented by two variables in ncm module in the hard disk firmware: the cur _ req _ cnt and the pre _ req _ cnt calculate a reduction ratio, the cur _ req _ cnt is used for counting the current IO request number in each second, the pre _ req _ cnt is used for counting the IO request number in each second before triggering temperature control (namely the IO request number under the condition of default maximum bandwidth), the two variables can reflect the read-write bandwidth size of the solid state disk, and the variable value is larger when the bandwidth is larger. The formula current _ req _ cnt 100/pre _ req _ cnt can be used to determine the ratio of the current bandwidth to the bandwidth before triggering temperature control.
In some embodiments, in step S6, decreasing the current value of the register by the value corresponding to the difference value according to the magnitude of the difference value, and returning to the step of determining the bandwidth reduction ratio until the bandwidth reduction ratio reaches the target reduction ratio, further comprising:
judging whether the difference value is larger than a first reference value or not;
in response to the difference being greater than a first reference value, decreasing the current value of the register by a value corresponding to the first reference value.
In some embodiments, further comprising:
and in response to the difference value being less than the first reference value and greater than a second reference value, decreasing the current value of the register by a value corresponding to the second reference value.
In some embodiments, further comprising:
and in response to the difference value being less than the second reference value and greater than a third reference value, decreasing the current value of the register by a value corresponding to the third reference value.
Specifically, the current reduction ratio is obtained in the timer, and if the current reduction ratio is greater than the target reduction ratio rate1(rate2) + D1, the value of the register is decremented by S2; if the current reduction ratio > target reduction ratio rate1(rate2) + D0, then subtract the value of register R by S1; if the current reduction ratio > the target reduction ratio rate1(rate2), then subtract the value of register R by S0; the value of the register is thus continuously decreased until the timer is exited when the current droop ratio is less than or equal to rate1(rate 2).
It should be noted that, as long as the current temperature triggers the adjustment of the temperature control bandwidth, the above operation is performed only once in the corresponding temperature interval, i.e. during the bandwidth adjustment, even if the detected temperature is still in the temperature interval, the above steps are not re-performed, but are continuously performed.
In some embodiments, the method proposed by the present invention may further include:
continuously acquiring the temperature of the hard disk;
judging whether the temperature of the hard disk is not greater than a third threshold value, wherein the third threshold value is smaller than the first threshold value;
and responding to the fact that the temperature of the hard disk is not larger than a third threshold value, and adjusting the current value of the register of the hard disk to be a default maximum value.
Specifically, after triggering the temperature control, if the temperature drops to T0, the value of the register R is restored to the default maximum value, and the bandwidth is also restored to the maximum value at this time.
In some embodiments, further comprising:
in response to the temperature being less than the first threshold, adjusting a value of a register of the hard disk to a default maximum value;
obtaining the total number of IO requests in a preset time period;
and calculating the initial IO request number in unit time according to the total IO request number and the length of a preset time period.
For example, if the temperature is lower than 70 ℃, the value of FPMPA is not changed, and the number of IO requests within 15s is continuously counted, and after dividing by 15, the initial IO request number is assigned to pre _ req _ cnt.
The method provided by the invention is characterized in that after the temperature control is triggered, the temperature rising speed of the solid state disk is controlled in a bandwidth control mode, and the bandwidth control is realized by modifying the value of the register. Controlling the bandwidth includes reducing the bandwidth to a certain proportion of the maximum bandwidth, and restoring the bandwidth to the maximum, wherein the bandwidth reduction is achieved by gradually reducing the value of the register R in steps, because the relationship between the value of the register R and the bandwidth is non-linear, and under some fio models, the register R maximizes, i.e., saturates, the bandwidth at a smaller value. The method for gradually reducing the value of the register R in a grading way can adapt to almost all fio models, namely the read-write bandwidth of the solid state disk can be reduced to a specified proportion under almost all fio models, and the accuracy of the reduction ratio can reach plus or minus 5 percent, so that a good temperature control effect is achieved. In addition, the method for gradually reducing the value of the register R in the grading grade is to divide the reduction number into three grades, so that the reduction speed and the reduction accuracy of the bandwidth can be considered.
