Description

Automatic testing method and device for abnormal power failure of solid state disk

Technical Field

The invention relates to the technical field of solid state disk performance testing, in particular to an automatic testing method and device for abnormal power failure of a solid state disk.

Background

At present, solid state disk products have been widely applied to various occasions, such as consumer-grade, industrial-grade, enterprise-grade and other application environments, due to the advantages of high speed, low power consumption and the like. The power failure test of the solid state disk is important for measuring the stability and reliability of the solid state disk product.

With the continuous improvement of the NAND process and the technical background that the capacity of single particles is gradually increased, many processes about abnormal power failure exist in the solid state disk product design and Firmware implementation processes to cover various possible power failure situations, and various corresponding related test technologies about abnormal power failure also come into play.

In the using process of a product, a user has two conditions of normal power failure and abnormal power failure due to system reasons, environmental factors, manual operation and the like.

Normal power-off condition: the normal power failure is that a user performs normal shutdown operation through an OS (operating system), and the operation can inform the solid state disk before the system is completely powered off, so that the solid state disk is provided with a certain time for performing background processing such as storage of cache data, logic and physical mapping tables, updating of internal metadata and the like, and the next time the whole system is powered on, the system can quickly respond to a command issued by a host and normally enter the OS and the like; for the normal power-off condition, the Test technology is convenient to realize, namely a shutdown command provided by an OS is used for shutting down the whole system, then a startup jumper on a Test PC or a Test Server mainboard is controlled, and a short-circuit signal is generated by using a relay and the like to achieve the startup purpose; therefore, the shutdown and the startup can be realized by sending commands, and the stability and the reliability of the normal power failure of the solid state disk product under the whole system can be evaluated by circularly testing the solid state disk product for multiple times (such as 1000 times);

abnormal power failure condition: the abnormal power failure is a situation where the user does not perform a normal shutdown operation through the OS, including but not limited to the following situations:

the power supply of the Test PC or the Test Server is unstable, so that the whole machine is powered off;

the used environment is subjected to factors such as power limitation, and the like, so that the used Test PC or the Test Server is wholly powered off;

under the condition that an operating system is halted, a user cannot perform forced restart and needs to adopt some power-off operations;

other situations;

once the abnormal power-off condition occurs, the system cannot provide a power-off notification for the solid state disk, so that some cache data, logic and physical mapping tables, internal metadata and the like existing in the system and the solid state disk cannot be completely updated, and the power-off condition may also occur in the programming process of the NAND, so that a physical page is damaged.

Therefore, the next time the whole system is powered on, the command issued by the corresponding host cannot be quickly and normally sent, and even data reading errors and data loss are caused, even the situation that the OS cannot be normally entered is caused. Therefore, at the beginning of design, the solid state disk product mainly considers the processing under the condition of abnormal power failure, and the firmware of the solid state disk product also has more complex logic for error processing and data recovery and reconstruction after power-on.

From the analysis of the actual situation of abnormal power failure, the Test PC or the Test Server can not supply power suddenly, the Test verification requires that the abnormal situation can be simulated and covered, and different Test cases are used for testing and evaluating the stability and the robustness of the solid state disk product under the abnormal power failure.

Particularly, under the condition of data reading and writing of the solid state disk, abnormal power failure is carried out, internal processing of firmware of the solid state disk is complex, various problems are easy to occur in the firmware, such as the condition that an OS cannot enter, data of the solid state disk is lost, and even the solid state disk cannot be identified by a system, the purpose of testing is to simulate the abnormal power failure condition to the greatest extent, and the reliable evaluation and verification structure and method are improved.

The prior testing technical scheme is as follows: the abnormal power failure test of the system is mainly simulated in the following two ways:

using a relay or the like: the control method is used for controlling the power-on and power-off jump pin on the Test PC or the Test Server mainboard, the control is used for simulating that a user forcibly presses a power-on and power-off key of the mainboard for more than 5 seconds, and the Test PC or the Test Server is powered off after 5 seconds. However, the abnormal power failure situation simulated in such a manner and plan is different, and the difference lies in that after the power-off key is forcibly pressed, a delay of more than 5 seconds is provided, and in this time, the OS has actually detected that the user presses the power-off key signal, and the OS may send a power failure notification to the solid state disk, so that the desired purpose cannot be completely achieved; the mode is only suitable for controlling the switching and shutdown jumper on the main board of the Test PC or the Test Server, and the mode cannot be used under the condition that the Test PC or the Test Server has no switching and shutdown jumper or is inconvenient to be connected independently;

and (3) manually removing a power supply mode: the tester manually removes (or shuts down) the power supply of the Test PC or the Test Server, for example, shuts down the power supply of the chassis (or cabinet) provided for the Test PC or the Test Server, so as to achieve the purpose of power-off of the whole machine. The testing technology better simulates the expected abnormal power failure condition, but the mode consumes a large amount of human resources, needs a large amount of manual monitoring and operation, and is inconvenient for batch deployment and statistical analysis of testing results.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

using a relay or the like: the method is different from the planned simulation abnormal power failure situation, and the difference lies in that after the power-off key is forcibly pressed, the time delay is more than 5 seconds, the OS actually detects the interrupt signal of the user pressing the power-off key in the time, the OS possibly sends a power failure notification to the solid state disk, and the expected purpose cannot be completely achieved; the mode is only suitable for controlling the switching and shutdown jumper on the main board of the Test PC or the Test Server, and the mode cannot be used under the condition that the Test PC or the Test Server has no switching and shutdown jumper or cannot be connected independently;

the method of manually removing the power supply is as follows: although the mode well simulates the expected abnormal power failure condition, a large amount of human resources are consumed, a large amount of manual monitoring and operation are needed, and a large amount of time is spent on manual operation;

in the process of manually detecting the test result, the possibility of misjudgment exists; meanwhile, due to inertia of manual detection, newly increased detection conditions or change of existing detection conditions are inconvenient;

the test flow does not lead in an automatic mode, so that the large-batch and long-time test deployment and the statistical analysis of test results are inconvenient;

the test and evaluation of the behavior of the solid state disk product under abnormal power failure involve more test scenes, and the existing test mode and the flow test are single, so that the subsequent change and expansion are not convenient.
