Description

Technical Field

[0001] This invention relates to the field of solid-state drive (SSD) storage, and in particular to a method and related equipment for detecting an over-temperature alarm function of a solid-state drive. Background Technology

[0002] With the rapid development of SSDs and the further acceleration of silicon-to-magnetic demagnetization, the use of NVMe SSDs has become more widespread. The NVMe specification is also constantly being updated, with new versions making relevant requirements and regulations for asynchronous events under various abnormal conditions. Furthermore, with the advancement of technology and the advent of the big data era, data storage security has become increasingly important. Therefore, the robustness, practicality, and reliability of the SMART (self-monitoring, analysis, reporting technology) function of solid-state drives (SSDs) have become even more crucial.

[0003] Currently, SMART alarm tools for detecting over-temperature conditions in operating system (Windows / Linux) environments are inefficient. They generally require prolonged periods of heavy read / write operations, or even a temperature chamber under specific environmental temperatures. This not only results in lengthy testing times and increased manpower for preparing the test environment—installing the operating system on the computer, running the read / write software, and observing the temperature—but also necessitates relying solely on manual observation to determine the outcome. It fails to generate detailed and reasonable log files for subsequent troubleshooting. Furthermore, it cannot verify whether the asynchronous events triggered by the SSD following the protocol requirements are functioning correctly or interfering with other functions. This requires relying on more expensive equipment, such as protocol analyzers, to observe whether events are triggered, but it cannot verify the robustness of this function according to a specific procedure. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method and related equipment for detecting the over-temperature alarm function of a solid-state drive.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a method for detecting over-temperature alarm function of solid-state drive, comprising the following steps:

[0006] S10. After the solid-state drive is powered on, set a temperature threshold below the current temperature value that is triggered when the power is off and is not saved. After the temperature threshold is triggered, restart the solid-state drive to check whether the over-temperature alarm function is normal.

[0007] S20. After the solid-state drive restarts, reset a temperature threshold below the current temperature value that is saved after power failure and can be triggered. After the temperature threshold is triggered, restart the solid-state drive again to check whether the over-temperature alarm function is normal.

[0008] S30. After the solid-state drive restarts, set a temperature threshold below the current temperature value that is triggered when the power is off and will not be saved. After the temperature threshold is triggered, send an asynchronous event request to the solid-state drive and test whether the read and write functions of the solid-state drive are normal.

[0009] Furthermore, step S10 specifically includes,

[0010] S11. After the solid-state drive is powered on, obtain the SMART status of the solid-state drive and confirm whether the SMART status of the solid-state drive is healthy.

[0011] S12. If the SMART status of the solid-state drive is healthy, obtain the current temperature value of the solid-state drive.

[0012] S13. Based on the current temperature value of the solid-state drive, set a temperature threshold that can be triggered below the current temperature value, and set the temperature threshold to not be saved when power is off;

[0013] S14. When the temperature of the solid-state drive is lower than the set temperature threshold, determine whether the temperature threshold has been successfully executed. If it has been successfully executed, confirm that the SMART status of the solid-state drive has changed to a critical warning status.

[0014] S15. If the SMART status of the solid-state drive is in a critical warning state, then restart the solid-state drive;

[0015] S16. After the SSD restarts, retrieve the SSD's SMART status again. If it is in a healthy state, it means that the power failure without saving function is in effect.

[0016] Furthermore, step S20 specifically includes,

[0017] S21. Reset a triggerable temperature threshold below the current temperature value, and save the temperature threshold after power failure.

[0018] S22. When the temperature value of the solid-state drive is lower than the reset temperature threshold, determine whether the temperature threshold has been successfully executed. If it has been successfully executed, confirm that the SMART status of the solid-state drive has changed to a critical warning status.

[0019] S23. If the SMART status of the solid-state drive is in a critical warning state, then restart the solid-state drive;

[0020] S24. After the SSD restarts, retrieve the SSD's SMART status again. If it is in a critical warning state, it means that the power-off save function is effective.

[0021] Furthermore, step S30 specifically includes,

[0022] S31. After the solid-state drive is powered on, obtain the SMART status of the solid-state drive and confirm whether the SMART status of the solid-state drive is healthy.

[0023] S32. If the SMART status of the solid-state drive is healthy, obtain the current temperature value of the solid-state drive.

[0024] S33. Based on the current temperature value of the solid-state drive, set a temperature threshold that can be triggered below the current temperature value, and set the temperature threshold to not be saved when power is off;

[0025] S34. When the temperature value of the solid-state drive is lower than the set temperature threshold, determine whether the temperature threshold has been successfully executed. If it has been successfully executed, confirm that the bit of the solid-state drive's SMART state that changes to the critical warning state is set.

[0026] S35. After the bit in the solid-state drive's SMART state changes to a critical warning state is set, send an asynchronous event request to the solid-state drive.

[0027] S36. Receive the asynchronous event sent back by the solid-state drive and determine whether the type of the asynchronous event is an over-temperature asynchronous event;

[0028] S37. If it is an asynchronous event that exceeds the temperature limit, then clear the asynchronous event count;

[0029] S38. Send a disk recognition command to the solid-state drive;

[0030] S39. If the disk is successfully recognized, perform a random read / write test on the solid-state drive to determine if the random read / write test is normal.

[0031] Furthermore, repeat steps S35-S39 at least 256 times to ensure normal random read / write operation of the hard drive.

[0032] Furthermore, in step S39, a random read / write test is performed on the solid-state drive to determine whether the random read / write test is normal. This specifically includes...

[0033] For random read / write tests of solid-state drives (SSDs), compare the data before and after the random read / write operation. If the data before and after the read / write operation are the same, the read / write operation is abnormal; if the data before and after the read / write operation are different, the data reading is normal.

[0034] Furthermore, the random read / write test time for the solid-state drive was two minutes.

[0035] The present invention also provides a solid-state drive over-temperature alarm function detection device, comprising,

[0036] The power failure non-save test module is used to set a temperature threshold below the current temperature value that can be triggered when the solid-state drive is powered on, and to restart the solid-state drive after the temperature threshold is triggered to check whether the over-temperature alarm function is normal.

[0037] The power-off save test module is used to reset a temperature threshold below the current temperature value that can be triggered for power-off save after the solid-state drive restarts, and to restart the solid-state drive again after the temperature threshold is triggered to check whether the over-temperature alarm function is normal.

[0038] The asynchronous event testing module is used to set a temperature threshold below the current temperature value for the SSD after it restarts, which is triggered when power is lost and not saved. After the temperature threshold is triggered, it sends an asynchronous event request to the SSD and tests whether the read and write functions of the SSD are normal.

[0039] The present invention also provides a computer device, the computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the solid-state drive over-temperature alarm function detection method as described above.

[0040] The present invention also provides a storage medium storing a computer program, which, when executed by a processor, can implement the solid-state drive over-temperature alarm function detection method as described above.

[0041] The beneficial effects of this invention are as follows: The solid-state drive over-temperature alarm function detection method of this solution can efficiently and comprehensively verify whether the alarm function of the solid-state drive is working properly after over-temperature, and whether it can still work properly after restarting, shutting down, or abnormal power failure after over-temperature. It can also simultaneously test whether the asynchronous over-temperature event function will affect the normal recognition and read / write of the hard drive. It uses a more scientific and comprehensive method to detect the functional module, thereby avoiding the failure of this function during end-user use and the failure to promptly remind users to improve the usage environment and back up data; thus avoiding the solid-state drive exceeding the design temperature limit, which would lead to complete damage to the SSD, data loss, and irreversible damage.

[0057] like Figure 3 As shown, step S10 specifically includes,

[0058] S11. After the solid-state drive is powered on, obtain the SMART status of the solid-state drive and confirm whether the SMART status of the solid-state drive is healthy.

[0060] S13. Based on the current temperature value of the solid-state drive, set a temperature threshold that can be triggered below the current temperature value, and set the temperature threshold to not be saved when power is off;

[0061] S14. When the temperature of the solid-state drive is lower than the set temperature threshold, determine whether the temperature threshold has been successfully executed. If it has been successfully executed, confirm that the SMART status of the solid-state drive has changed to a critical warning status.

[0062] S15. If the SMART status of the solid-state drive is in a critical warning state, then restart the solid-state drive;

[0063] S16. After the SSD restarts, retrieve the SSD's SMART status again. If it is in a healthy state, it means that the power failure without saving function is in effect.

[0064] like Figure 4 As shown, step S20 specifically includes,

[0065] S21. Reset a triggerable temperature threshold below the current temperature value, and save the temperature threshold after power failure.

[0066] S22. When the temperature value of the solid-state drive is lower than the reset temperature threshold, determine whether the temperature threshold has been successfully executed. If it has been successfully executed, confirm that the SMART status of the solid-state drive has changed to a critical warning status.

[0067] S23. If the SMART status of the solid-state drive is in a critical warning state, then restart the solid-state drive;

[0068] S24. After the SSD restarts, retrieve the SSD's SMART status again. If it is in a critical warning state, it means that the power-off save function is effective.

[0069] like Figure 5 As shown, step S30 specifically includes,

[0070] S31. After the solid-state drive is powered on, obtain the SMART status of the solid-state drive and confirm whether the SMART status of the solid-state drive is healthy.

[0071] S32. If the SMART status of the solid-state drive is healthy, obtain the current temperature value of the solid-state drive.

[0072] S33. Based on the current temperature value of the solid-state drive, set a temperature threshold that can be triggered below the current temperature value, and set the temperature threshold to not be saved when power is off;

[0073] S34. When the temperature value of the solid-state drive is lower than the set temperature threshold, determine whether the temperature threshold has been successfully executed. If it has been successfully executed, confirm that the bit of the solid-state drive's SMART state that changes to the critical warning state is set.

[0074] S35. After the bit in the solid-state drive's SMART state changes to a critical warning state is set, send an asynchronous event request to the solid-state drive.

[0075] S36. Receive the asynchronous event sent back by the solid-state drive and determine whether the type of the asynchronous event is an over-temperature asynchronous event;

[0076] S37. If it is an asynchronous event that exceeds the temperature limit, then clear the asynchronous event count;

[0077] S38. Send a disk recognition command to the solid-state drive;

[0078] S39. If the disk is successfully recognized, perform a random read / write test on the solid-state drive to determine if the random read / write test is normal.

[0079] Among them, steps S35-S39 are repeated no less than 256 times to ensure that the hard drive can perform random read and write operations normally.

[0080] In step S39, a random read / write test is performed on the solid-state drive (SSD) to determine whether the random read / write test is normal. This specifically includes...

[0081] To perform random read / write tests on a solid-state drive (SSD), check the address where the data is written. Compare the data before and after the random read / write operation. If the data before and after the read / write are the same, the read / write operation is abnormal; if the data before and after the read / write are different, the data reading is normal.

[0082] The random read / write test of the solid-state drive lasted for two minutes.

[0083] The hardware requirements for the above embodiments are as follows: Solid-state drive under test: a solid-state drive supporting power-loss protection; Computer: a laptop or desktop computer supporting dual hard drive bays; Adapter board: a Ulink M.2 dedicated PSPA adapter board. Software requirements are as follows: Operating system: Windows 10; Testing software: Ulink DriveMaster 2018 NVMe; Test script: a self-written DriveMaster test script.

[0084] This embodiment utilizes Ulink's DriveMaster software to write test scripts to perform checks and tests on this function. By setting a temperature threshold, it simulates the solid-state drive's operating temperature exceeding the set safe temperature and continuously increasing under specific conditions. Then, it checks whether the solid-state drive's SMART status triggers the relevant critical warning messages normally. By sending different settings to simulate a solid-state drive restart, it checks whether the flag is retained or cleared as expected. Then, by simulating the host sending asynchronous event requests to the solid-state drive, it confirms whether the solid-state drive can correctly respond to the asynchronous event of over-temperature. It tests whether the cleared flag and the unclear flag can be handled normally. Finally, it identifies the solid-state drive and performs random read and write tests to verify whether the solid-state drive's functionality is affected.

[0085] The beneficial effects of this invention are as follows: The solid-state drive over-temperature alarm function detection method of this solution can efficiently and comprehensively verify whether the alarm function of the solid-state drive is working properly after over-temperature, and whether it can still work properly after restarting, shutting down, or abnormal power failure after over-temperature. It can also simultaneously test whether the asynchronous over-temperature event function will affect the normal recognition and read / write of the hard drive. This method detects the functional module in a more scientific and comprehensive way, thereby avoiding the failure of the function during end-user use and the failure to promptly remind users to improve the usage environment and back up data. This also avoids the solid-state drive exceeding the design temperature limit, which could lead to complete damage to the SSD, data loss, and irrecoverable damage.
