Description
Technical Field
The present invention relates to the field of solid state storage technologies, and in particular, to a method, an apparatus, a system, and an electronic device for detecting power failure of a solid state disk.
Background
Solid state disk (Solid State Drive, SSD) is widely used in various fields due to its strong random read-write capability. The solid state disk can be installed on a host (host) to serve as a storage medium of the host, and the host transmits data to the solid state disk, so that the solid state disk writes the transmitted data into the solid state disk for storage.
In the working process, the solid state disk needs to be powered by the host computer so as to maintain the normal working of the solid state disk. In some application scenarios, the host may terminate the power supply of the solid state disk (hereinafter referred to as abnormal power failure) without notifying the solid state disk in advance, for example, the power supply of the host is suddenly turned off. In the abnormal power failure process, the solid state disk may not have enough time to write the data issued by the host into a nonvolatile storage unit (such as NAND Flash, a nonlinear Flash storage unit), but only store the issued data in a cache of the solid state disk. Abnormal power loss may result in data loss of the host, affecting the data security of the host.
In the related art, a power supply module can be arranged in the solid state disk, and certain electric quantity is stored in the power supply module, so that the solid state disk can be powered when the solid state disk is abnormally powered down, and the solid state disk can continuously complete data writing (hereinafter referred to as power-down processing). The mechanism is a power failure protection mechanism of the solid state disk. To reduce the possibility of data loss due to abnormal power loss, it is necessary to maintain the normal operation of the power-down protection mechanism.
However, the power supply module has limited power, the duration of the power-down processing process is short, the duration is usually in the order of milliseconds, and it is difficult for staff to effectively collect the state of the solid state disk in the power-down processing process, so that when the power-down protection mechanism cannot normally operate, the problem occurring in the power-down protection mechanism is analyzed, and the problem is solved in time, so that the power-down protection mechanism can normally operate.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to more clearly explain the method for detecting the power failure of the solid state disk provided by the embodiment of the invention, a possible application scenario of the method for detecting the power failure of the solid state disk provided by the embodiment of the invention will be described. It can be understood that this example is only one possible application scenario of the method for detecting the power failure of the solid state disk provided by the embodiment of the present invention, and in other possible embodiments, the method for detecting the power failure of the solid state disk provided by the embodiment of the present invention may also be applied to other application scenarios, and the embodiment does not limit this.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a solid state disk power failure detection system according to an embodiment of the present invention, which may include:
solid state disk 110, tester 120, PDU (Power Distribution Unit ) 130, controller 140, external power supply 150.
The solid state disk 110 includes a power supply module, which is configured to supply power to the solid state disk 110 when the solid state disk 110 performs power failure processing. The power supply module may be any component with energy storage and energy supply functions, for example, in a possible embodiment, the power supply module may be formed by a capacitor, and may store a certain amount of electricity in the capacitor by charging the capacitor, and supply power when the solid state disk 110 is powered down by discharging the capacitor. The maximum electric quantity which can be stored by the power supply module is lower than a preset electric quantity threshold, the preset electric quantity threshold is different according to different application scenes, for example, in some application scenes, the preset electric quantity threshold can be the power consumption of the solid state disk in a power-down state for 10 milliseconds, and in other application scenes, the preset electric quantity threshold can also be the power consumption of the solid state disk in the power-down state for 5 milliseconds. It can be understood that, because the maximum electric quantity that the power supply module can store is smaller, the power supply module can not maintain the solid state disk in the power-down state for a long time by means of the stored electric quantity.
The solid state disk 110 is installed in the testing machine 120, and the testing machine 120 supplies power for the normal operation of the solid state disk 110. The solid state disk 110 may be mounted on the tester 120 through a SATA (Serial Advanced Technology Attachment ) interface or a PCIE (Peripheral Component Interconnect Express, a high speed serial computer expansion bus standard) interface plugged onto the tester 120.
The PDU130 is used for supplying power to the testing machine 120, and since the solid state disk 110 installed on the testing machine 120 is powered by the testing machine 120, the PDU130 indirectly supplies power to the solid state disk 110. For example, PDU130 may power a power supply in test machine 110 and the power supply in test machine 120 powers solid state disk 110. It will be appreciated that if the PDU130 terminates powering the tester 120, the solid state disk 110 theoretically enters a power down state.
The controller 140 may be connected to the solid state disk 110 through a UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiver Transmitter) interface, and in other possible embodiments, may also be connected to the solid state disk 110 through other interfaces to receive signals output by the solid state disk 110. It can be appreciated that if the solid state disk 110 enters a power-down state due to the PDU130 terminating to supply power to the testing machine 120, the power-down protection mechanism of the solid state disk 110 is triggered, and at this time, the testing machine 120 cannot work due to lack of power supply. Therefore, in this embodiment, the solid state disk 110 cannot send a signal to the controller 140 through the testing machine 120 in the power-down processing, and the signal needs to be directly sent to the controller 140 through an interface between the solid state disk 110 and the controller 140, such as a UART interface, so that the controller 140 can detect the power-down processing of the solid state disk 110. In other possible embodiments, the solid state disk 110 may also indirectly send a signal to the controller 140 through other electronic devices other than the testing machine 120, which is not limited in this embodiment.
Taking the solid state disk power failure detection system as an example, the solid state disk power failure detection method provided by the embodiment of the invention can be applied to a controller therein. Referring to fig. 2, fig. 2 is a schematic flow chart of a method for detecting power failure of a solid state disk according to an embodiment of the present invention, which may include:
s201, controlling the solid state disk to execute a preset operation instruction through the testing machine.
S202, controlling an external power supply to supply power to a power supply module and controlling the PDU to terminate supplying power to a testing machine in the process of executing an operation instruction by the solid state disk.
S203, an execution result of the solid state disk to execute the preset operation instruction is obtained.
S204, determining whether the execution result is matched with an expected result preset for a preset operation instruction.
And S205, if the execution result is not matched with the expected result, controlling the external power supply to continuously supply power to the power supply module, and controlling the PDU to continuously be in a state of stopping supplying power to the testing machine so as to enable the solid state disk to be maintained in a power-down state.
By adopting the embodiment, the abnormal power failure situation can be simulated for the solid state disk by stopping the power supply of the testing machine, and whether the power failure protection mechanism of the solid state disk can normally operate can be judged by comparing the execution result actually output by the solid state disk with the expected result. When the power-down protection mechanism of the solid state disk cannot normally operate, the power supply module is continuously charged by the external power supply, and the state that the solid state disk is powered by the power supply module is maintained, so that the solid state disk can be kept in a power-down state for a long time, a worker can collect the state of the solid state disk in the power-down processing process for a sufficient time, and the problem of the power-down protection mechanism can be effectively analyzed.
In S201, a control script may be stored in advance in the control machine, and the control machine executes the control script, so as to control the solid state disk to execute a preset operation instruction through the test machine according to an instruction in the control script. The preset operation instructions can also be different according to different application scenes.
For example, the preset operation instruction may include an operation instruction for controlling the solid state disk to output a preset character string in the power-down process, and in a possible embodiment, to distinguish a character string output by the solid state disk in the power-down process from a character string output by the solid state disk in the non-power-down process, a special character string may be used as the preset character string, where the special character string is a character string that cannot be (or has a low probability of being) output by the solid state disk in the non-power-down process. By adopting the embodiment, the probability of recognizing the character string output by the solid state disk in the non-power-down processing process as the preset character string can be reduced, and the detection accuracy is improved.
In S202, the control machine may directly control the working state of the external power source, and control the external power source to supply power to the power supply module, for example, the control machine may control the external power source to switch from the off state to the on state through the internet of things, so that the external power source supplies power to the power supply module. In other possible embodiments, the control machine may not directly control the working state of the external power supply, so as to indirectly control the external power supply to supply power to the power supply module.
For example, in one possible embodiment, as shown in fig. 3, the solid state disk power failure detection system may be configured such that the external power supply 150 is connected to the power supply module in the solid state disk 110 through the relay 160, and the external power supply 150 is kept in an on state, and when the relay 160 is turned on, a circuit between the external power supply 160 and the power supply module is in a path state, and at this time, the external power supply 150 supplies power to the power supply module. When the relay 160 is turned off, the circuit between the external power supply 150 and the power supply module is in an open state, and the external power supply 150 is terminated to supply power to the power supply module.
In this embodiment, the control machine may be configured to control the relay to switch to an on state, so as to control the external power source to supply power to the power supply module. The control machine may be connected to the relay through a USB (Universal Serial Bus ) interface to control the state of the relay. By adopting the embodiment, the control machine can indirectly control the external power supply to supply power to the power supply module through the relay without switching the working state of the external power supply, and the state switching of the relay is simpler than the state switching of the external power supply, so that the implementation difficulty of the solid state disk power failure detection method provided by the embodiment of the invention can be reduced by adopting the embodiment.
Similarly, the control machine can directly control the working state of the PDU to control the PDU to terminate to supply power to the testing machine, or indirectly control the PDU to terminate to supply power to the power supply module, and the principle is the same as that of the control machine for controlling the external power supply, and the description is omitted here.
It can be appreciated that the occurrence of abnormal power failure often has randomness, so in one possible embodiment, in order to make the simulated abnormal power failure situation more approximate to the actual situation, the controller may control the external power supply to supply power to the power supply module and control the PDU to terminate supplying power to the testing machine according to a time generated randomly during the process of executing the preset operation instruction by the solid state disk. The time can be generated by adopting different random algorithms, such as a chaotic equation, a random number table and the like, according to different actual requirements, and the embodiment is not limited to the time. By adopting the embodiment, the simulated abnormal power failure situation is more similar to the actual situation, so that the detection result can better reflect the running condition of the power failure protection mechanism of the solid state disk under the actual situation.
In S203, the control machine may acquire the execution result actively or passively. For example, the execution result sent by the solid state disk may be received, or the execution result may be read from a specific storage path in the solid state disk.
In S204, the matching of the execution result with the expected result may mean that the execution result is identical to the expected result, or that the similarity between the execution result and the expected result is higher than a preset similarity threshold. Taking an example that the preset operation instruction includes an operation instruction for controlling the solid state disk to output a preset character string in the power-down processing process, the method may be that whether the execution result includes the preset character string is determined, if the execution result includes the preset character string, the execution result is determined to be matched with the expected result, and if the execution result does not include the preset character string, the execution result is determined to be not matched with the expected result.
In one possible embodiment, the preset operation instruction may include an operation instruction for controlling the solid state disk to output a preset character string when the power-down process is completed. It can be understood that, because the preset character string is output when the power-down processing is completed, and the solid state disk often has relevance among various stages in the power-down processing process, if the execution result includes the preset character string, the solid state disk can be considered to have successfully executed various stages for completing the power-down processing, that is, the power-down processing process of the solid state disk is normal. If the execution result does not include the preset character string, the solid state disk can be considered to have abnormality in at least one stage in the power failure processing process. By adopting the embodiment, the calculation amount required by comparing the execution result with the expected result can be effectively reduced, and the detection efficiency is improved.
In S205, it may be understood that if the execution result matches the expected result, the power-down processing procedure of the solid state disk may be considered to be normal, and if the execution result does not match the expected result, the power-down processing procedure of the solid state disk may be considered to be abnormal. When the power failure processing process is abnormal, the external power supply is controlled to continue to supply power to the power supply module, the PDU is in a state of stopping supplying power to the testing machine, and then the testing machine cannot normally supply power to the solid state disk, so that the solid state disk is powered by the power supply module, the solid state disk can be maintained in the power failure state, the electric quantity of the external power supply can be considered to be sufficient, the solid state disk can be maintained in the power failure state for a long time, and the staff can conveniently collect the state parameters of the power failure state of the solid state disk, so that the problems caused by a power failure protection mechanism can be effectively analyzed. The control manner of the PDU and the external power supply may be referred to the related description in S202, and will not be repeated here.
In one possible embodiment, if the execution result matches the expected result, the external power source may be controlled to terminate supplying power to the power supply module. If the execution result matches with the expected result, the power-down processing process of the solid state disk can be considered to be normal, so that the solid state disk does not need to be maintained in the power-down state for a long time. By selecting this embodiment, energy consumption can be saved.
It will be appreciated that the analysis of abnormal power loss as described above tends to be random, and thus it may be difficult to detect potential problems with the power loss protection mechanism by single solid state drive power loss detection. In one possible embodiment, as shown in fig. 4, it may include:
s401, controlling the PDU to supply power for the tester and the solid state disk.
The control manner of the PDU may be referred to the related description in S202, and will not be repeated here.
S402, controlling the solid state disk to execute a preset operation instruction through the testing machine.

S404, an execution result of the solid state disk to execute the preset operation instruction is obtained.
This step is the same as S203, and reference may be made to the foregoing description about S203, which is not repeated here.
S405, determining whether the execution result matches an expected result preset for the preset operation instruction, if the execution result does not match the expected result, executing S406, and if the execution result matches the expected result, executing S407.
This step is the same as S204, and reference may be made to the foregoing description about S204, which is not repeated here.

This step is the same as S205, and reference may be made to the foregoing description about S205, which is not repeated here.
S407, controlling the external power supply to stop supplying power to the power supply module, and returning to the step S401.
The termination condition of the cycle may be different according to different actual requirements, for example, the cycle may be terminated after a preset number of cycles, or the cycle may be terminated after a cycle termination instruction input by a related person is received, which is not limited in this embodiment. With this embodiment, the possibility of detecting the potential problem of the power-down protection mechanism can be improved by repeated detection.
