Referring to fig. 2 and fig. 3, fig. 2 is a schematic view of an application scenario of the SSD temperature control performance balancing method according to the embodiment of the invention. Fig. 2 is a schematic flowchart of a method for balancing SSD temperature control performance according to an embodiment of the present invention. The SSD temperature control performance balancing method is applied to a server. This server carries out the data interaction with solid state disk, and the server acquires the SMART temperature when solid state disk is in read-write operation in real time to reduce solid state disk IO performance when the SMART temperature exceeds first threshold value, appear going up and down repeatedly of SMART temperature when resuming solid state disk IO performance after falling SMART temperature back, then carry out the safe management and control of temperature, realize taking into account temperature and performance balance's processing simultaneously in control SSD temperature, the bad user experience influence that arouses when reducing the temperature management and control.

Referring to fig. 5, when the solid state disk performs read/write operations, that is, the solid state disk is forced to be in an idle state during IO read/write, processing of any IO command is stopped, so as to achieve the purpose of reducing read/write performance. Read-write performance can be accurately adjusted by adjusting the ratio of the processing time of the IO in the idle state to the processing time of the IO command, when the temperature is low, the SSD is in a full-speed running state, and the IO is always in a busy state; be in the control by temperature change needs, when carrying out the performance and slowly descending, can be through the time proportion that real-time adjustment IO is in busy state and IO is in idle state, this proportion is that IO is in the time of busy state/(IO is in the time of busy state + IO is in idle state), the concrete proportion of performance promptly to accurate regulation and control performance, control IO performance slowly descends, and final balance is about 50%, and then reaches SSD temperature control performance's balance.

Fig. 3 is a schematic flowchart of a method for balancing SSD temperature control performance according to an embodiment of the present invention. As shown in fig. 3, the method includes the following steps S110 to S180.

S110, acquiring SMART temperature of the solid state disk in normal read-write operation to obtain initial temperature.

In this embodiment, the initial temperature refers to a SMART temperature when the solid state disk performs a read/write test operation in a low temperature state and the Performance is in a normal state, and the normal read/write operation refers to a situation when the solid state disk performs the read/write test operation in the low temperature state and the Performance is in the normal state, and is marked as Best Performance.

And S120, judging whether the initial temperature exceeds a first threshold value.

In this embodiment, the first Threshold is a temperature Threshold set according to an actual situation, and when the acquired SMART temperature exceeds the first Threshold, the temperature control performance balancing function is started, and the first Threshold is labeled as Thermal Threshold.

In this embodiment, this step is mainly performed to determine whether the initial temperature exceeds the first threshold for the first time, and since there is a subsequent second ramp after the IO performance is reduced, a non-first ramp may be separately adjusted according to an actual situation, or a processing manner consistent with the first threshold exceeding mode may be set.

And S130, if the initial temperature exceeds a first threshold, reducing the IO performance of the solid state disk to a first set performance.

In this embodiment, the first setting performance is half of the read-write performance of the solid state disk when the initial temperature does not exceed the first threshold.

Specifically, the IO idle parameter of the solid state disk is adjusted, and the IO performance of the solid state disk is reduced to a first set performance according to the IO idle parameter.

In this embodiment, the IO idle parameter refers to a ratio of the processing time of the IO command to the IO idle state. The first threshold is a temperature control threshold set according to actual conditions, and when the SMART temperature exceeds the first threshold, the temperature control performance needs to be balanced.

As shown in fig. 6, specifically, when the temperature rises from low temperature to the first threshold for the first time, the temperature control performance balancing function is started, the IO idle parameter is adjusted in real time according to the time difference of entering the temperature control performance balancing state, and the IO performance is slowly decreased to 50% of the SMART temperature when the solid state disk is in the low temperature state for performing the read/write test operation and the performance is in the normal state, although this percentage may be adjusted according to the actual situation.

Of course, when the temperature ramps up from low temperature to the first threshold multiple times, the decrease may be used when the recovery performance ramps up to the first threshold after not decreasing the performance.

S140, acquiring a corresponding SMART temperature when the IO performance of the solid state disk is reduced to obtain a first intermediate temperature.

In the present embodiment, the first intermediate temperature refers to a SMART temperature at which IO performance of the solid state disk is reduced.

S150, judging whether the first intermediate temperature reaches a second threshold value.

In this embodiment, the second threshold is the first threshold minus 3 ℃, and in other embodiments, the second threshold may also be the first threshold minus other values.

If the first intermediate temperature does not reach the second threshold, the step S140 is executed;

and S160, if the first intermediate temperature reaches a second threshold value, recovering the IO performance of the solid state disk to the normal read-write performance, and acquiring the corresponding SMART temperature to obtain a second intermediate temperature. When the temperature falls back to the first threshold value of-3 ℃, the read-write performance is recovered to be the normal read-write performance; the 3 ℃ non-constant value can be set as the difference parameter to other values.

In this embodiment, the second intermediate temperature is a SMART temperature at which the IO performance of the solid state disk is reduced and then the IO performance of the solid state disk is restored to the normal read/write performance. The second intermediate temperature is obtained to verify whether the temperature will rise immediately after the IO performance is recovered, and to determine whether the SSD is always at a higher temperature due to the environmental temperature or ventilation.

And S170, judging whether the second intermediate temperature is increased back relative to the first intermediate temperature.

If it is determined whether the second intermediate temperature has risen back relative to the first intermediate temperature, it can be verified whether the following occurs: the SMART temperature slowly decreases when the IO performance decreases but immediately rises after the IO performance recovers, the temperature repeatedly rises and falls, and the SSD is in a relatively high-temperature state; when this occurs, the performance adjustment IO cannot meet the requirement for temperature control performance balance, and the performance needs to be adjusted again.

In the embodiment, it is verified that the SMART temperature slowly decreases when the IO performance decreases but immediately increases after the IO performance recovers, and the temperature repeatedly increases and decreases; in other embodiments, the IO performance of the solid state disk may be reduced again after the temperature is set to rise and fall repeatedly for a period of time, so as to drive the solid state disk to perform the security state, and the actual selection may be determined according to the actual situation.

And S180, if the second intermediate temperature is increased back to the first intermediate temperature, reducing the IO performance of the solid state disk again to drive the solid state disk to be in a safe state.

In an embodiment, referring to fig. 4, the step S180 may include steps S181 to S184.

And S181, reducing the IO performance of the solid state disk in normal read-write operation to a second set performance.

In this embodiment, the second set Performance is 60% of the IO Performance of the solid state disk during normal read/write operations, that is, Safety Best Performance; specifically, the second setting performance is 60% of the IO performance during normal read/write operations, and of course, in other embodiments, the above-mentioned 60% may be other values, which may be determined according to actual situations.

S182, reducing the IO performance of the solid state disk to a third set performance, and acquiring the corresponding SMART temperature to obtain a third intermediate temperature.

In the present embodiment, the third setting Performance refers to 30% of the second setting Performance, that is, the third setting Performance is 30% of the second Performance, that is, Safety Performance. Of course, in other embodiments, the above-mentioned 30% may be other values, which may be determined according to actual situations.

As shown in fig. 7, after the period when the SMART temperature is at the relatively high temperature is counted for a certain period, controlling the temperature to enter the safe state becomes a primary consideration, and this period may be referred to as a safe state period, and the normal Performance of this period is adjusted to 60% of the IO Performance during normal read/write operations, i.e., 60% of Best Performance, and this parameter is adjustable, so that the IO Performance of the solid state disk, i.e., Thermal Performance, is correspondingly adjusted to 30% of the normal Performance, i.e., 30% of the second setting Performance.

And S183, judging whether the third intermediate temperature is reduced to a third threshold value.

In this embodiment, the third Threshold refers to a Threshold of a set Safety state, i.e., Safety Exit Threshold, and this value may be set according to actual situations.

And S184, if the third intermediate temperature is reduced to a third threshold value, recovering the IO performance of the solid state disk to a second set performance, acquiring the corresponding SMART temperature to update the initial temperature, and executing the step S120.

If the third intermediate temperature does not drop to the third threshold value, the step S182 is executed.

The SMART temperature slowly drops to a third Threshold value, namely Safety Exit Threshold, the IO Performance is recovered to Best Performance, and the SSD is determined to be in a low-temperature normal state at the moment; if the temperature rises again, the above steps S110 to S180 are repeated to perform the temperature-performance balance control.

If the initial temperature does not exceed the first threshold, step S110 is executed.

According to the SSD temperature control performance balancing method, the SMART temperature of the solid state disk during read-write operation is obtained and judged, when the SMART temperature exceeds the first threshold value, the IO performance is recovered after the IO performance of the solid state disk is reduced to the second threshold value, and when the IO performance is recovered, the temperature rises immediately, the IO performance is reduced, so that the solid state disk is adjusted to enter a safe state, balanced regulation and control of the performance according to the SMART temperature of the solid state disk are realized, the effect of flexibly balancing the temperature and the performance is achieved, and the user experience is improved.

Fig. 8 is a flowchart illustrating a method for balancing SSD temperature control performance according to another embodiment of the invention. As shown in fig. 8, the SSD temperature control performance balancing method of this embodiment includes steps S210-S300. Steps S210 to S240 are similar to steps S110 to S140 in the above-described embodiment, and steps S270 to S300 are similar to steps S150 to S180 in the above-described embodiment, and are not repeated herein. The added steps S250 to S260 in the present embodiment are explained in detail below.

S250, judging whether the first intermediate temperature falls back relative to the initial temperature;

s260, if the first intermediate temperature does not fall back relative to the initial temperature, keeping the IO performance of the solid state disk at a first set performance, acquiring a corresponding SMART temperature, updating the first intermediate temperature according to the acquired SMART temperature, and executing judgment S270;

if the first intermediate temperature falls back with respect to the initial temperature, the step S270 is performed.

When the SMART temperature does not fall back, the IO performance of the solid state disk is kept at the first set performance, so that the SMART temperature slowly falls back.
