[0017] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application. In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially changed or adjusted in a manner obvious to those skilled in the art. Therefore, the order in the specification and the drawings is only for clear description of an embodiment and does not mean a necessary order, unless otherwise stated that a certain order must be followed.

[0018] In the description of the present application, one or more means one or more, more than two means more than two, greater than, less than, more than, etc. are understood as not including the number, above, below, etc. are understood as including the number. If it is described as first, second, it is only used to distinguish technical features for the purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0019] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, the "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0020] The storage pressure test method for rapid positioning according to the embodiments of the present application is a verification process for verifying whether a storage system meets the predetermined target through systematic means, and mainly verifies core indexes such as read-write performance, data consistency, fault recovery capability, etc. The test process adopts tools such as FIO and vdbench to realize dynamic data collection, and evaluates system reliability through simulation of node failure, multi-client concurrency and other scenarios.

[0021] However, the existing storage pressure test method fills data packets in a fixed mode and checks the cyclic redundancy check (CRC) value at the tail of the data packet, which cannot distinguish logical addresses or data errors occurring in the storage pressure test process, and full CRC checking will cause a problem of large test overhead, thereby resulting in low test efficiency. Although the existing storage pressure test method uses a replacement CRC method, such as using SHA-256 algorithm for checking, it will increase the calculation delay. Secondly, the improved storage pressure test method uses a freezing mechanism, that is, a piece of non-volatile cache is used to temporarily store error information data, but there is a problem of data redundancy and occupation of additional storage space.

[0022] Based on the above, the present application provides a storage pressure test method for rapid positioning and a storage medium thereof. The method includes receiving a write command and obtaining a test data packet, wherein the test data packet is provided with a starting logical block address, a write block number, a logical unit and a check value; performing a check operation according to the starting logical block address and the check value to obtain a check result; when the check result is successful, performing a write operation according to the starting logical block address and the write block number; when the check result is failed, saving a state log of the write operation and stopping the write operation, and outputting positioning information according to the logical unit, the check result and the state log. Through the check operation combining the starting logical block address and the check value, data checking can be quickly performed, and rapid positioning can be performed in the case of data error exception, thereby improving the accuracy and test efficiency of the storage pressure test. At the same time, the check type can be adjusted according to the test environment, thereby solving the problem that data errors caused by external conditions such as temperature, signal interference, etc. in the storage pressure test process are difficult to quickly locate, and realizing real-time capture of exceptions through construction of test data packet writing and multiple checks, thereby improving test efficiency and analysis accuracy.

[0023] Please refer to Figure 1 , Figure 1The flow of the fast positioning storage pressure test method applied to the control unit is shown. As shown in Figure 1 The fast positioning storage pressure test method provided by the embodiment of the present application is applied to the control unit, and includes the following steps: In step S1100, a test data packet is constructed, and the test data packet is provided with a starting logical block address, a write block number, a logical unit and a check value; wherein the starting logical block address and the check value are used to perform a check operation according to a check level determined by a preset check level and a logical unit to obtain a check result; the starting logical block address and the write block number are used to perform a write operation, and the logical unit is used to output positioning information according to the check result.

[0024] It can be understood that the test data packet is an important link in the data management and test process, and a reasonable storage strategy can ensure the safety, accessibility and reusability of data. In the embodiment of the present application, in order to quickly locate the fault, the starting logical block address, the write block number, the logical unit and the check value need to be configured in the test data packet. The logical block address (LBA) is a general mechanism for describing the data block on the computer storage device, and is generally used in the auxiliary memory device such as a hard disk. The LBA can refer to the address of a data block or the data block pointed to by an address. In actual application, when the operating system reads or writes data, it first locates to a specific device through a device number, then determines a specific partition through a partition number, and finally calculates the specific data block position using the LBA. It should be noted that the block is the smallest unit of the erase operation, which is composed of multiple pages; the write operation is in units of pages, but rewriting data requires whole block erasing and rewriting. By configuring the number of write blocks, the total amount of data written can be accurately controlled, and in turn the amount of data for storage stress testing can be accurately controlled. The logical unit is the basic unit of data processing and storage. A logical unit is a concept used in computer systems, databases, or data processing to organize and process information. In data processing, a logical unit can be a data record, a file, a table, a collection, or other data that can be stored and managed for subsequent processing and analysis. In computer systems, files, folders, and directories can also be considered logical units. Logical units can help storage stress testing to more effectively organize and manage data. The design of logical units is crucial to the efficiency and accuracy of data processing systems. A reasonable logical structure design can greatly improve the speed and accuracy of data processing, while reducing errors and redundancy. In addition, logical units also help improve data security, as logical units can ensure data integrity and consistency. By reasonably dividing and organizing logical units, data storage, retrieval, and updating can be more effectively performed. In the embodiments of the present application, by recording the logical unit, the logical unit that has errors or abnormalities during the test process can be quickly located, improving test efficiency and analysis accuracy.

[0025] It should be noted that the check value is a value obtained by a certain operation to verify the correctness of a set of data. Specifically, data verification is a verification operation to ensure data integrity, and the check value is a value calculated from the original data by a specified algorithm in this process, which is used for subsequent data integrity verification. In practical applications, the data receiving party recalculates the check value using the same algorithm as the data sending party for the received data. If the check values calculated twice are the same, it means that the data has not changed during transmission or storage, i.e., the data is complete.

[0026] It should be noted that the control unit and the storage unit are different roles in a computing component or system. In the embodiments of the present application, the control unit is the host (Host), which usually refers to a computer that serves as a control center or main system, responsible for managing and coordinating the work of other devices. The storage unit is a device (Device), which refers to an external device or subsystem that depends on the host, and usually needs the control of the host to work. In some embodiments, the control unit and the storage unit are two core roles in a USB protocol-based network system. The control unit serves as the master of the USB network, responsible for initiating communication, managing connected devices, and distributing power. Typical representatives include computers, laptops, and other devices with USB host controller architecture. The storage unit is a slave that passively responds to Host instructions, relies on Host to provide power, and performs specific functions. For example, USB flash drives, printers, cameras, and other peripherals that need to be connected to the Host through USB.

[0027] Step S2100, a write command is sent to the storage unit, and the write command includes a test data packet.

[0028] It can be understood that, in the write process of the storage pressure test, the control unit sends a write command with a test data packet to the storage unit, so that the storage unit obtains the starting logical block address, the number of write blocks, the logical unit and the check value in the test data packet, and ensures that the storage unit can perform a write operation according to the starting logical block address and the number of write blocks after passing the check according to the check value, thereby performing a write pressure test. In the case where the check fails, the storage unit can output positioning information according to the logical unit to realize real-time capture of exceptions, thereby improving the write test efficiency and analysis accuracy.

[0029] Please refer to Figure 2 , Figure 2 The application further provides a flow of a fast positioning storage pressure test method applied to a control unit. As shown in Figure 2 , the fast positioning storage pressure test method applied to the control unit includes the following steps: Step S1200, a test data packet is constructed, and the test data packet is provided with a starting logical block address, a number of read blocks, a logical unit and a check value; wherein the starting logical block address and the check value are used to perform a check operation according to a preset check level and a check level determined by the logical unit to obtain a check result; the starting logical block address and the number of read blocks are used to perform a read operation, and the logical unit is used to output positioning information according to the check result.

[0030] It can be understood that, in the read process of the storage pressure test, the test data packet is constructed in the same way as in the above step S1100, and the test data packet is provided with a starting logical block address, a number of read blocks, a logical unit and a check value. By configuring the number of read blocks, the total amount of read data can be accurately controlled, and thus the amount of data of the storage pressure test can be accurately controlled. The starting logical block address, the logical unit and the check value in the test data packet are set and function in the same way as described above, and thus will not be described here.

[0031] Step S2200, a read command is sent to the storage unit, and the read command includes a test data packet.

[0032] It can be understood that, in the reading process of the storage pressure test, the control unit sends a read command with a test data packet to the storage unit, so that the storage unit obtains the starting logical block address, the read block number, the logical unit and the check value in the test data packet, and ensures that the storage unit can pass the check through the check value, and then performs a read operation according to the starting logical block address and the read block number, to perform the read pressure test. In the case of failing to pass the check, the storage unit can output positioning information according to the logical unit to realize real-time capture of exceptions, and improve the read test efficiency and analysis accuracy.

[0033] Step S3200, the completion instruction is accepted, and a check operation is performed on the test data packet in the completion instruction.

[0034] It can be understood that, after the storage unit completes the read operation, a completion instruction including read data and a test data packet is sent to the control unit. After the control unit receives the completion instruction, a check is performed through the starting logical block address and the check value. In the case of passing the check, the read test process is completed. In the case of failing to pass the check, the storage unit can output positioning information according to the logical unit to realize real-time capture of exceptions, and improve the read test efficiency and analysis accuracy.

[0035] Please refer to Figure 3 , Figure 3 A flow of a fast positioning storage pressure test method applied to a storage unit provided by another embodiment of the present application is shown. As Figure 3 shown, the fast positioning storage pressure test method of the embodiment of the present application is applied to the storage unit, and includes the following steps: Step S1300, a write command is received, and a test data packet is obtained, wherein the test data packet is provided with a starting logical block address, a write block number, a logical unit and a check value.

[0036] It can be understood that, in the storage pressure test process, the storage unit receives a write command sent by the control unit, wherein the test data packet in the write command is provided with a starting logical block address, a write block number, a logical unit and a check value. The specific content and function of the test data packet are consistent with the test data packet constructed by the control unit in the above step S1100, and will not be repeated here.

[0037] Step S2300, the control unit combines the preset check level and the check level determined by the logical unit to perform a check operation according to the starting logical block address and the check value, and obtains a check result.

[0038] It can be understood that, as known from the above, the LBA is a logical address system used by a storage device such as a hard disk to identify a data storage location. When data is written, the system will store the data to the specified location according to the LBA. The verification process verifies the integrity of the data by comparing whether the actual data in the storage device is consistent with the expected data. If there is a difference, there may be data corruption or write error.

[0039] Referring to Figure 5 , Figure 5 A specific implementation process diagram of another embodiment of the above step S2300 is shown. As shown in Figure 5 , the test data packet further includes a reserved field, and the above step S2300 at least includes the following steps: Step S2310, determining the verification type according to the reserved field.

[0040] It can be understood that, in actual application, in order to cope with different test levels and requirements, the verification type of the storage stress test needs to be set through the reserved field. Specifically, different levels can be set by external conditions, such as high and low temperature, temperature cycle, power failure, etc. The test setting level is higher, and the normal temperature environment test setting level is lower. It should be noted that, generally, before the storage stress test is started, the verification level needs to be determined in advance by setting the reserved field according to the difference of logical units or test scenarios, and the verification level of the entire storage stress test is determined.

[0041] Referring to Figure 6 , Figure 6 A specific implementation process diagram of another embodiment of the above step S2310 is shown. As shown in Figure 5 , step S2310 at least includes the following steps: Step S2311, obtaining an environmental parameter, the environmental parameter including temperature, power supply.

[0042] It can be understood that, since different external conditions are set in the test scenario to perform storage testing, in order to simulate the actual device operating environment, different performance requirements are made on the test process and results of the storage device. Therefore, in different test environments, the verification type needs to be set according to the environmental parameter. The environmental parameter includes temperature, power supply, etc. Specifically, generally, the storage device operates in an environmental temperature of 25℃-85℃. Within this interval, it can be considered as normal temperature test, since the device operates stably within this temperature interval, therefore, in the normal temperature test process, the storage test setting level is lower. In the power supply environment, when there is a power failure in the environmental parameter, the possibility of device error is higher, therefore, the storage test setting level is higher, so as to accurately locate and analyze the error occurred in the test process.

[0043] Step S2312, determining the reserved field according to the environmental parameter.

[0044] It can be understood that after obtaining the environmental parameters, the reserved field in the test data packet is determined. In a specific application, the reserved field directly represents the verification level of the storage stress test. For example, if the reserved field is zero, the verification level of the storage stress test is the lowest, and the corresponding verification length is 0, that is, no additional verification is performed on the data bytes, and only the LBA address is verified. When the reserved field is not zero, the data bytes corresponding to the verification length are verified according to the actual requirements and the level allocated by the logical unit, so as to improve the accuracy of the verification.

[0045] Step S2320, performing a verification operation according to the verification type, the logical unit, the starting logical block address, and the verification value.

[0046] It can be understood that, in order to ensure the accuracy of data read and write verification, the verification is performed by means of forced starting logical block address verification combined with optional verification value. In actual application, whether to perform verification on the data bytes is determined according to the reserved field and the verification type, and then the verification length is determined according to the verification type and the logical unit, so as to ensure that the verification result can fully reflect the errors existing in the stress test process and perform rapid positioning and analysis.

[0047] Please refer to Figure 7 , Figure 7 a specific implementation process diagram of another embodiment of the above step S2320 is shown. As Figure 5 shown, step S2320 at least includes the following steps: Step S2321, when the reserved field is zero, performing a verification operation according to the starting logical block address.

[0048] It can be understood that when the reserved field is zero and the test level is the lowest, the verification operation is performed according to the starting logical block address, that is, LBA verification. The LBA verification is mainly used for data consistency verification in a storage system, and the data integrity of the logical block address is detected to ensure the storage reliability. Specifically, the LBA verification is performed by a verification algorithm to verify the LBA number and the corresponding data block, so as to ensure the address correctness, that is, the LBA number read or written is not wrong due to errors in the transmission process; and to ensure the data integrity, that is, the data block pointed to by the LBA is not damaged, tampered or lost due to hard disk bad tracks. In actual application, the LBA verification is an important mechanism to ensure the accuracy and integrity of hard disk data positioning, and is widely used in normal operation and data maintenance of storage devices.

[0049] Step S2322, when the reserved field is not zero, performing a verification operation according to the verification type and the verification length corresponding to the logical unit.

[0050] It can be understood that when the reserved field is non-zero, the test level is low, and on the basis of the LBA check, the check operation also needs to be performed according to the check type and the check length corresponding to the logical unit.

[0051] In a specific application, different values of the reserved field represent different levels, and the higher the level, the more the amount of check data. For example, if the check level is A, only the first 64*A bytes are checked. Different levels can be determined by the test scene or the logical unit, for example, the logical unit sets the level 3, and then the logical unit checks 192B per 4KB of data in the process of processing data, and when the logical unit sets the level 1, the logical unit only checks 64B per 4KB of data, so the data check can be checked in different amounts through the level set by the logical unit.

[0052] Step S3300, when the check result is successful, performing a write operation according to the starting logical block address and the write block number.

[0053] It can be understood that when the check result is successful, the storage device needs to perform a write operation. Specifically, in the test process of Universal Flash Storage (UFS), a write operation needs to be performed according to the starting logical block address and the write block number. The UFS is a high-performance storage solution, and has significant advantages in speed, data transmission efficiency and interface technology compared with the embedded Multi Media Card (eMMC). The UFS is based on serial data transmission technology, and although there are only two data channels between the internal storage unit and the host, the actual data transmission speed is much higher than that of the eMMC flash based on parallel technology.

[0054] Step S4300, when the check result is failed, saving the state log of the write operation, and stopping the execution of the write operation, and the control unit outputs the positioning information according to the logical unit, the check result and the state log.

[0055] It can be understood that when the check result is failed, in order to ensure rapid fault positioning, the state log needs to be saved immediately when an error is triggered, such as the last 16 CMD histories, multiple Unipro / PHY register states, the current power mode, buffer usage and part of the read-write related variables, to realize complete freezing of the fault scene. Especially in the case of dead loop, hardware triggered abnormal interruption, etc., when the check result is failed, the control unit saves the state log of the write operation immediately, and stops the execution of the write operation. At the same time, according to the logical unit, the check result and the state log, the positioning information is outputted to determine the logical unit where the error occurs.

[0056] Please refer toFigure 4 , Figure 4 The figure shows the flow of a fast positioning storage pressure test method applied to a storage unit according to another embodiment of the present application. As shown in the figure, the fast positioning storage pressure test method according to the embodiment of the present application comprises the following steps: Figure 4 Step S1400, receiving a read command and obtaining a test data packet, wherein the test data packet is provided with a starting logical block address, a read block number, a logical unit and a check value.

[0057] It can be understood that, in the storage pressure test process, the storage unit receives a read command sent by the control unit, wherein the test data packet in the read command is provided with a starting logical block address, a read block number, a logical unit and a check value. The specific content and function of the test data packet are consistent with the test data packet constructed by the control unit in the above-mentioned step S1200, and will not be repeated here.

[0058] Step S2400, performing a read operation according to the starting logical block address and the read block number, and writing the read data into the test data packet.

[0059] It can be understood that, in order to accurately read data, a read operation is performed according to the starting logical block address and the read block number. At the same time, in order to verify the accuracy of the read data, the read data needs to be written into the test data packet. In actual application, the read data is written into the test data packet by instruction, which belongs to the prior art and will not be repeated here.

[0060] Step S3400, the control unit combines the preset check level and the check level determined by the logical unit to perform a check operation according to the starting logical block address and the check value, and obtains a check result.

[0061] It can be understood that, after the read data is written into the test data packet, in order to ensure the integrity of the data, a check operation needs to be performed according to the starting logical block address and the check value, wherein the specific check process is consistent with the above-mentioned step 2300, and will not be repeated here.

[0062] Step S4400, when the check result is successful, sending a completion instruction containing the test data packet to the control unit.

[0063] It can be understood that, in order to accurately transmit the read data, when the check result is successful, the test data packet containing the read data needs to be written into the completion instruction, and the completion instruction needs to be sent to the control unit, so that the control unit performs the check operation as described in the above-mentioned steps.

[0064] ​Step S5400: When the verification result is a failure, save the status log of the write operation and stop the write operation. The control unit outputs the location information based on the logic unit, the verification result and the status log.

[0065] Understandably, when the verification result fails, in order to ensure rapid fault location, it is necessary to immediately save the status log upon triggering the error. The specific process is the same as step S4300 above, and will not be repeated here.

[0066] It should be noted that the storage stress testing method provided in this application can effectively locate data transmission errors such as bit flips. Bit flips refer to the phenomenon where a bit in binary data changes from 0 to 1 or from 1 to 0, which can lead to data corruption, program crashes, and other problems. Causes include: hardware failures, such as memory failures, electromagnetic interference, voltage fluctuations, temperature changes, and other physical factors that may alter the state of storage units; software errors, such as incorrect bit operations or buffer overflows; and radiation effects, where high-energy particles alter the values ​​of storage units. In practical applications, this application successfully detects bit flips caused by high and low temperatures and quickly locates abnormal data errors, effectively improving the detection rate by 80%.

[0067] like Figure 8 As shown, Figure 8 This is a structural diagram of a test data packet provided in one embodiment of this application. The test data packet is 4KB in size, wherein the first 4 bytes and the last 5-8 bytes are used to store the LBA address, the first 4-7 bytes record the number of times the address is written, bytes 8-11 record the logical unit, the last 4 bytes store the CRC32 check value, and the other bytes are filled with fixed values. Figure 8 As shown in (a), the LBA address is 100, this address has been written to 66 times, and the number of logical units written is 0. For example... Figure 8 As shown in (b), the LBA address is 100, the number of writes to this address is 55, and the number of write logic units is 5.

[0068] It should be noted that the number of write times refers to the number of times a specific LBA address is written with data. Each time a write operation is performed on the address, such as writing new data or overwriting old data, the write counter is incremented. For solid state disks (SSD), the number of write times is particularly important, as the performance and reliability of the SSD will gradually decrease as the number of write times increases. This is because SSDs use flash memory to store data, and the storage cells of the flash memory gradually wear out after being written to, which can eventually lead to data loss or performance degradation. In the prior art, SSD manufacturers provide tools to monitor and report the number of write times for each LBA, and regularly checking and monitoring the number of write times for LBAs can help predict the health and performance degradation of the hard disk. At the same time, during use, the write position of the data can be balanced as much as possible to avoid excessive use of certain areas.

[0069] It should be noted that CRC32 has strong error detection capability, and also has the advantages of small overhead and easy implementation of encoder and detection circuit. Specifically, from the error detection capability, the probability of errors that CRC cannot detect is very low. From the performance and overhead, CRC is much better than parity and arithmetic and checksum methods. Therefore, in the field of data storage and data communication, CRC32 is widely used.

[0070] In actual application, the control unit carries out pressure test process, adopts instruction queue (command queue) to carry out test, and adopts MTK6877 test in hardware aspect. In the write test process, when abnormal problems occur in pre-write data due to external environmental factors, such as electromagnetic interference, temperature influence, abnormal transmission signal, etc., the existing test method will write the error data or flipped data as normal data into the storage medium because it does not have the function of detecting and positioning abnormal scene. The storage pressure test method provided by the embodiment of the present application can identify abnormal data in time before writing into the storage medium, save abnormal logs and stop write operation, avoid writing abnormal data into the storage medium, and effectively improve the positioning speed and abnormal monitoring accuracy.

[0071] In the read test process, the read data types include discrete data and bulk data. Because there is a part of the cache area in the control unit for storing the mapping relationship, frequent reading and writing of the mapping relationship is avoided. In bulk data reading, the existing test method cannot be operated frequently because of continuous data reading, so that the error site is not covered or not completely covered, and it takes 30 minutes to locate the specific reason. The storage stress test method provided in the embodiment can identify abnormal data in time and save abnormal logs. In actual testing, it only takes about 20 minutes to complete positioning, and the positioning speed is improved by 33%. In addition, in the discrete data reading process, because the data is discontinuous, the mapping relationship needs to be frequently operated, so that the error site is partially covered or completely covered. The existing test method usually takes 1 hour to locate, while the storage stress test method provided in the embodiment can complete positioning in about 30 minutes, the positioning speed is improved by 50%, and the accuracy is improved by 50%. In addition, as the test environment becomes worse, such as high and low temperature-25-100 degrees cycle and the like, the positioning speed and accuracy are significantly improved.
