Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The inventor finds that, in the conventional SSD monitoring method, a main control chip is used to obtain working parameters of the SSD, such as temperature, current, power, and other information, and then the obtained working parameters are uploaded to a host through a bus, and the host performs data analysis and determines the operating condition of the SSD according to the analysis result. However, when the main control chip is abnormal, the SSD working parameters cannot be obtained or the obtained working parameters are abnormal due to the main control chip itself, the host cannot determine the working condition of the SSD or the determination is inaccurate.
In order to solve the problem, in the embodiment of the application, two controllers of a solid state disk, namely a first controller and a second controller, are used for simultaneously acquiring working parameters of an SSD, when the working parameters respectively sent by the first controller and the second controller are received, whether a difference value of the two working parameters exceeds a preset threshold value is judged, if the difference value does not exceed the preset threshold value, indicating that the two working parameters are normal values, whether the SSD is abnormal is judged according to the two working parameters and historical working parameters, and therefore, compared with the prior art that the working parameters are acquired by only one controller to judge the running state of the SSD, a redundancy mechanism is added, namely, the running condition of the SSD is judged under the condition that the two working parameters are normal, the judgment accuracy is improved, so that a server can be timely notified for maintenance when the SSD is abnormal, the stable operation of the storage device is ensured, and the loss of data in production and life is reduced.
The following describes in detail a specific implementation manner of the method and the device for detecting a solid state disk in the embodiment of the present application by using an embodiment with reference to the accompanying drawings.
Exemplary method
Referring to fig. 1, which is a flowchart of a detection method for a solid state disk provided in an embodiment of the present application, where the solid state disk includes a first controller and a second controller, as shown in fig. 1, the method is applied to a processor, and specifically may include:
s101: and receiving the first working parameter of the solid state disk sent by the first controller and the second working parameter of the solid state disk sent by the second controller.
In this embodiment, both the first controller and the second controller may obtain the working parameters of the solid state disk, and send the obtained working parameters to the processor. The working parameters may be temperature, current, power, and the like.
It should be noted that the working parameters collected by the first controller and the second controller are the same, that is, when the first working parameter includes the temperature of the solid state disk, the second working parameter also includes the temperature of the solid state disk; when the first operating parameter includes the temperature and the current of the solid state disk, the second operating parameter also includes the temperature and the current of the solid state disk.
In practical application, the first controller may be a NAND Flash main control chip in the SSD, and the second controller may be an external Microcontroller Unit (MCU) of the SSD. In specific implementation, a temperature sensor and a current sensor may be added to the periphery of the SSD, and the main control chip may read the temperature or the current of the SSD during operation from the temperature sensor or the current sensor through an Inter-Integrated Circuit (IIC); the MCU can also read the operating temperature or current of the SSD from the temperature sensor or the current sensor through the IIC, and then the main control chip and the MCU can send the obtained current and temperature to the processor through a System Management Bus (SMBus).
S102: and judging whether the difference value of the first working parameter and the second working parameter exceeds a preset threshold value.
In this embodiment, when the processor receives the first working parameter and the second working parameter, the difference between the first working parameter and the second working parameter is first calculated, and then it is determined whether the difference exceeds a preset threshold. The preset threshold value can be set according to the running condition of the SSD.
It can be understood that, since the first operating parameter is a parameter such as temperature and current of the SSD obtained by the first controller during operation, and the second operating parameter is a parameter such as temperature and current of the SSD obtained by the second controller during operation, theoretically, parameter values of the two operating parameters should be equal, and in consideration of an error in obtaining and transmitting the operating parameters in practical application, when comparing the two operating parameters, a certain error value, that is, a preset threshold value, is allowed to occur.
When the difference value between the two working parameters is smaller than or equal to the preset threshold, it indicates that the difference between the two working parameters is small, and the difference can be used for judging the running condition of the SSD, so that when the difference value does not exceed the preset threshold, S103 is executed.
In practical application, in order to improve the accuracy of judgment, the first controller and the second controller can acquire the working parameters of the SSD for multiple times, and then the processor averages a plurality of first working parameters sent by the first controller to serve as a first average value; averaging a plurality of second working parameters sent by a second controller to serve as a second average value; and calculating a difference value between the first average value and the second average value, judging whether the difference value exceeds a preset threshold value, and if not, executing S103.
S103: and judging whether the solid state disk is abnormal or not according to the historical working parameters, the first working parameters and the second working parameters.
In this embodiment, when the difference between the first working parameter and the second working parameter does not exceed the preset threshold, it is indicated that the second working parameter and the first working parameter are normal values, and whether the solid state disk is abnormal is determined according to the historical working parameter, the first working parameter, and the second working parameter. The historical operating parameter, the first operating parameter and the second operating parameter at least comprise one of temperature, current and power.
In practical application, the historical operating parameters are operating parameters which are stored by the processor and transmitted by the first controller and the second controller in the past time, and the operating parameters represent parameters for the SSD to operate normally. That is, comparing the first working parameter and the second working parameter with historical working parameters, and if the first working parameter and the second working parameter are both consistent with the historical working parameters, indicating that the SSD operates normally; and if the first working parameter and the second working parameter are not consistent with the historical working parameter, indicating that the SSD operates abnormally, and informing the server of maintaining in time. In specific implementation, the first working parameter and the second working parameter may be respectively different from the historical working parameter, and when the difference values both satisfy the preset condition, the correspondence is indicated, otherwise, the correspondence is not indicated.
For convenience of understanding, for example, the first operating parameter includes a first temperature of 31 degrees, the second operating parameter includes a second temperature of 32 degrees, the preset threshold is plus or minus 2 degrees, the historical temperature is 34 degrees, the preset condition is less than or equal to plus or minus 3 degrees, and through calculation, the difference value between the first temperature and the second temperature does not exceed the preset threshold, and meanwhile, the difference values between the first temperature, the second temperature and the historical temperature meet the preset condition, the SSD operates normally; if the historical temperature 35, the difference value between the first temperature and the historical temperature is 4 degrees, and the preset condition is not met, the SSD works abnormally.
In practical application, when the SSD is judged to be working normally according to the first working parameter, the second working parameter and the historical working parameter, the historical working parameter may be updated by using the first working parameter and the second working parameter, so that the processor may update the stored working parameter, and perform subsequent judgment by using the updated historical working parameter. In a specific implementation, the working parameters may be stored for the first controller and the second controller, that is, for the first controller, corresponding to the first historical working parameter, and for the second controller, corresponding to the second historical working parameter, whether the solid state disk is abnormal is determined according to the first working parameter and the first historical working parameter, and whether the solid state disk is abnormal is determined according to the second working parameter and the second historical working parameter.
When the SSD works abnormally according to the first working parameter, the second working parameter and the historical working parameter, abnormal events are recorded, so that maintenance personnel can check and maintain according to the log.
In a possible implementation manner of the embodiment of the present application, when the first operating parameter and the second operating parameter exceed a preset threshold, the method further includes: judging whether the first working parameter and/or the second working parameter are null or not according to the historical working parameters; when the first working parameter is a null value, determining that the first controller works abnormally; and/or determining that the second controller works abnormally when the second working parameter is a null value.
In this embodiment, when the difference between the first working parameter and the second working parameter exceeds the preset threshold, it indicates that at least one of the two working parameters is abnormal, and in order to determine the abnormal working parameter, during the specific implementation, it is determined whether the first working parameter and the second working parameter are null values, and if the first working parameter is null value, it indicates that the first controller is abnormal in operation; similarly, if the second operating parameter is a null value, the second operating parameter is determined to be an abnormal value, indicating that the second controller is abnormal in operation.
In practical application, when any one of the two working parameters is null, the difference between the two working parameters is defined as infinite, so that the difference between the two working parameters exceeds a preset threshold, and when the difference exceeds the threshold, the working parameter is abnormal, so that the abnormal working parameter can be further judged.
When the first controller or the second controller is abnormal due to downtime, in order to ensure normal operation of the first controller or the second controller, the embodiment of the present application further provides a method for solving the abnormality of the controller, which specifically includes: when the first controller works abnormally and the second controller works normally, an abnormal signal is sent to the second controller, so that the second controller resets the first controller according to the abnormal signal; or when the second controller works abnormally and the first controller works normally, sending an abnormal signal to the first controller so that the first controller resets the second controller according to the abnormal signal.
In practical application, the first controller can be connected with a reset interface of the second controller through a General Input/Output (General Input Output) interface, the second controller is connected with the reset interface of the first controller through a GPIO interface, when only the first controller works abnormally, the processor sends an abnormal signal to the second controller, and the second controller sends a reset signal to the reset interface of the first controller through the GPIO interface according to the received abnormal signal so as to restart the first controller; similarly, when only the second controller works abnormally, the processor sends an abnormal signal to the first controller, and the first controller sends a reset signal to the reset interface of the second controller through the GPIO interface according to the received abnormal signal so as to restart the second controller. The abnormal signal may carry an identifier of the abnormal controller, so that another controller may reset the controller corresponding to the identifier according to the identifier.
In this embodiment, the first controller may also be connected to the reset interface of the second controller through another interface, which is not limited herein.
It can be understood that after the controller is restarted, whether the controller is recovered to normal or not can be judged according to the working parameters sent by the controller, and if the controller is recovered to normal, the controller is shut down when running; if the storage device is not normal, reporting an abnormal event to the server so as to inform a user of timely processing and avoid influencing the normal use of the storage device.
It can be seen from the above embodiments that, in the embodiment of the present application, the two controllers of the solid state disk, that is, the first controller and the second controller, are used to simultaneously acquire the working parameters of the SSD, and when the working parameters respectively acquired by the first controller and the second controller are received, it is determined whether the difference between the two working parameters exceeds the preset threshold, and if the difference does not exceed the preset threshold, it is determined whether the SSD is abnormal according to the two working parameters and the historical working parameters, and it can be seen that the method provided in the embodiment of the present application increases a redundancy mechanism compared with the prior art that only one controller is used to acquire the working parameters to determine the running state of the SSD, and determines the running condition of the SSD under the condition that the working parameters sent by the two controllers are both normal, thereby improving the accuracy of the determination, so that the server can be timely notified to perform maintenance when the SSD is abnormal, the stable operation of the storage device is ensured, and the loss of data in production and life is reduced.
In addition, when any one of the two controllers is abnormal, the other controller can be used for resetting the abnormal controller, so that a mechanism for processing the abnormal condition is added, the abnormal operation of the SSD caused by the downtime is prevented, and the running reliability of the SSD is improved. Referring to fig. 2, which is a flowchart for detecting an SSD exception according to an embodiment of the present disclosure, as shown in fig. 2, first receive a first working parameter sent by a first controller and a second working parameter sent by a second controller, determine whether a difference between the two working parameters exceeds a preset threshold, if not, determine an SSD running condition according to a historical working parameter, the first working parameter, and the second working parameter, and obtain the working parameter again; if the two working parameters exceed the preset threshold, judging whether the two working parameters have empty values, if not, recording abnormal working parameters, and acquiring data again; if the two working parameters are both null values, the two controllers can be reset by other equipment, and then data is acquired again; when the first parameter is null, the first controller is judged to be abnormal, an abnormal signal is sent to the second controller, the second controller resets the first controller, abnormal working parameters are recorded, and data is obtained again; and if the first working parameter is not a null value, sending an abnormal signal to the first controller, resetting the second controller by the first controller, recording the abnormal working parameter, and re-acquiring the data.
