Description

[0001] This invention relates to the field of hard disk technology, and in particular to a hard disk command detection method, a hard disk command detection device, an electronic device, and a computer-readable storage medium. Background Technology

[0002] With the development of demand for various remote data services such as cloud storage and cloud computing, data storage is increasingly being deployed on remote servers. Consequently, the requirements for data storage response speed are also increasing, along with demands for cost control and functionality. In this context, solid-state drives (SSDs) have been invented to adapt to these technological advancements, and their ultra-fast response speed and large import / export capacity offer significant advantages over traditional hard disk drives (HDDs).

[0063] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] Existing technologies typically use hard drive stress testing tools to perform read and write tests on solid-state drives (SSDs). However, this method only observes I / O commands on the host side and cannot observe the latency distribution of individual commands, thus failing to fully assess the hard drive's performance. To address this problem, this invention acquires the time information and execution count of each command executed by the hard drive. Based on the time information and a preset time threshold corresponding to the command, it determines the number of timeouts for each command and records statistical information about the hard drive's command execution. This allows for monitoring the number of timeouts for each command processed by the hard drive, enabling a more accurate assessment of the hard drive's performance.

[0065] Reference Figure 1 The diagram illustrates a flowchart of a hard disk command monitoring method according to an embodiment of the present invention. The method is applied to a monitoring device connected to a hard disk, and the method may specifically include the following steps:

[0066] Step 101: Send at least one command to the hard disk.

[0067] In this embodiment of the invention, the performance status of a hard drive can be monitored using a monitoring device. The monitoring device is connected to the hard drive, which can be a solid-state drive (SSD) or other types or models of hard drives; this invention does not impose specific limitations on this. When monitoring the hard drive, the monitoring device can send at least one command to the hard drive. After receiving the command, the hard drive executes the corresponding command and sends the execution result back to the monitoring device, thereby checking the hard drive. The monitoring device can be a host device or other devices; this invention does not impose specific limitations on this either. In this invention, the attributes of the commands sent by the monitoring device to the hard drive can be I / O commands or other commands. To more accurately monitor the performance status of the hard drive, the more attributes corresponding to the commands executed by the hard drive, the more accurate the monitoring results will be. This invention does not impose specific limitations on the attributes of the commands sent by the monitoring device to the hard drive.

[0068] In one embodiment, the monitoring device can write at least one command to the submission list of the hard disk, so that the hard disk can retrieve the command from the submission list. After the hard disk retrieves the command, it can execute the retrieved command. After the hard disk completes the execution of the retrieved command, it can write the execution result to the completion queue. The monitoring device can retrieve the execution result corresponding to the command from the completion queue. The execution result can include a first timestamp of each time the hard disk retrieves the command from the submission list, and a second timestamp of each time the hard disk completes the execution of the command and writes it to the completion queue. Each command has a corresponding first timestamp and second timestamp. For example, if a monitoring device writes three commands, A, B, and C, to the submission list on a hard drive, then the first timestamp will also have three values: A1, B1, and C1. First timestamp A1 is the time when the hard drive retrieves command A from the submission list, first timestamp B1 is the time when the hard drive retrieves command B from the submission list, and first timestamp C1 is the time when the hard drive retrieves command C from the submission list. The second timestamp will also have three values: A2, B2, and C3. Second timestamp A2 is the time when the hard drive writes the command A to the completion queue after execution, second timestamp B2 is the time when the hard drive writes the command B to the completion queue after execution, and second timestamp C2 is the time when the hard drive writes the command C to the completion queue after execution.

[0069] Step 102: Obtain the time information and execution number of each time the command is executed by the hard disk.

[0070] In this embodiment of the invention, after the monitoring device sends at least one command to the hard drive, it can obtain the time information and execution number of each command execution. In this invention, the hard drive can execute each command multiple times. Each time a command is executed, the monitoring device can obtain the time information and execution number of the hard drive's command execution. The time information can include a first timestamp for each command acquisition and a second timestamp for each command execution completion. For example, if the monitoring device sends a command A to the hard drive, and the hard drive executes command A twice, the monitoring device can obtain the first timestamp A1 for the first acquisition of command A, and the second timestamp A11 for the completion of command A corresponding to the first acquisition of command A; and the first timestamp A2 for the second acquisition of command A, and the second timestamp A22 for the completion of command A corresponding to the first acquisition of command A. The first and second timestamps correspond to the same command execution.

[0071] Step 103: Determine the number of timeouts for executing the command based on the time information and the preset time threshold corresponding to the command.

[0072] In this embodiment of the invention, after the monitoring device obtains the time information and number of times each command is executed by the hard disk, it can determine the number of timeouts for executing the command based on the time information and the preset time threshold corresponding to the command. The preset time threshold can be set according to actual needs, and the preset time threshold corresponding to each command can be different. The specific setting value and method are not specifically limited in this invention.

[0073] In one embodiment, the number of timeouts for executing commands in this invention can be determined as follows: the difference between the second timestamp and the first timestamp is used as the first execution time for each command; the number of timeouts for each command is determined based on the first execution time and the preset time threshold corresponding to the command. For example: if the time of first acquisition of command A is A1, i.e., the first timestamp of the first execution of command A is A1, and the completion time corresponding to the first acquisition of command A is A2, i.e., the second timestamp of the first execution of command A is A2, then subtracting the first timestamp A1 from the second timestamp A2 yields the first execution time D1 corresponding to the first execution of command A. The first execution time D1 corresponding to the first execution of command A, combined with the preset time threshold corresponding to command A, can be used to determine whether the first execution of command A timed out. Similarly, this can be used to determine whether the hard disk times out each time it executes a command, and to determine the number of timeouts for each command.

[0074] In one embodiment, the number of timeouts for each command execution is determined based on the first execution time of each command and the corresponding preset time threshold. This can be done as follows: compare the first execution time of each command execution with the corresponding preset time threshold; determine the first number of commands whose first execution time is greater than the preset time threshold, and use this first number as the number of timeouts for the command execution. For example, if the hard drive executes three commands: two commands A and one command B, the first execution time of the first command A is D1, the first execution time of the second command A is D2, and the first execution time of the first command B is D3. The preset time thresholds for command A and command B are E1 and E2, respectively. Compare D1 and D2 with E1, and compare D3 with E2. We find that D1 and D2 are both less than E1, and D3 is greater than E2. Therefore, the number of commands whose first execution time is greater than the preset time threshold can be determined to be 1, meaning the hard drive timed out once during the three command executions, specifically during the execution of command B.

[0075] In this embodiment of the invention, the hard drive receives a command and has been executing it. However, due to some factor, the command has not been executed successfully and remains in the "in execution" state. In reality, the hard drive has timed out while executing the command. In this case, because the timestamp of the command's completion is not obtained, it is impossible to determine whether the command has timed out, which may lead to errors in determining the number of timeouts for the hard drive's command execution. To make the determination of the number of timeouts for command execution more accurate, this invention can determine the number of timeouts for the hard drive's command execution as follows: determine a second number of commands currently executing on the hard drive that have timed out; determine the number of timeouts for successfully executing the command based on time information and a preset time threshold corresponding to the command; and take the sum of the second number of commands and the number of timeouts for successfully executed commands as the total number of timeouts for the hard drive's command execution. For example: if the second number of commands currently executing on the hard drive that have timed out is determined to be 3, and the number of timeouts for successfully executed commands is determined to be 2 based on time information and a preset time threshold corresponding to the command, then the sum of the second number of commands (3) and the number of timeouts for successfully executed commands (2) is taken as the total number of timeouts for the hard drive's command execution (5).

[0076] In one embodiment, determining the second number of commands that are currently being executed and have timed out on the hard disk can be achieved by: detecting commands currently being executed on the hard disk; determining a first timestamp and the current time corresponding to each command being executed; using the difference between the current time and the first timestamp corresponding to each command being executed as the second execution time of each command being executed; comparing the second execution time of each command being executed with a preset time threshold corresponding to each command being executed; and determining the second number of commands whose second execution time is greater than the preset time threshold from the commands being executed.

[0077] For example: If commands A1, A2, and A3 are detected being executed on the hard drive, these three commands can be the same command, meaning the same command is being executed three times, or they can be different commands, meaning different commands are being executed once each. Taking the case where the three commands are the same command, we can determine the first timestamps corresponding to commands A1, A2, and A3 as B1, B2, and B3, respectively, and the current time as C. The differences between the current time C and the first timestamps B1, B2, and B3 are D1, D2, and D3, respectively. Therefore, the second execution times corresponding to commands A1, A2, and A3 are D1, D2, and D3, respectively. Comparing these second execution times D1, D2, and D3 with a preset time threshold E, we find that second execution times D1 and D2 are less than the preset time threshold E, while second execution time D3 is greater than the preset time threshold E. Therefore, we can determine that the second number of commands among commands A1, A2, and A3 whose second execution time is greater than the preset time threshold is 1, and that command A3 timed out.

[0078] Step 104: Record the statistical information of the hard disk executing the command.

[0079] In this embodiment of the invention, after determining the number of timeouts for executing commands, the monitoring device can record statistical information about the hard drive's command execution and determine the hard drive's performance status based on this statistical information. The statistical information may include: command information for each command, a first timestamp, a second timestamp corresponding to each command, a preset time threshold, the number of executions, and the number of timeouts. When the ratio of the number of timeouts to the total number of command executions is less than a preset reference value, it indicates that the hard drive's performance status is excellent. For example, if the total number of command executions is 100, the number of timeouts is 2, and the preset reference value is 5%, then the ratio of the number of timeouts to the total number of command executions is 2%, which is less than the preset reference value of 5%, indicating that the hard drive monitored by the monitoring device has excellent performance.

[0080] In one embodiment, after recording statistical information of commands executed by the hard disk, the monitoring device can generate a statistical table according to a preset format based on the statistical information, and then output and / or save it. For example, the monitoring device can generate a statistical table according to the table format shown in Table 1 below.

[0081]

[0082] Table 1

[0083] After generating the statistical table, it can be output to the user, allowing them to intuitively understand the status of the hard drives monitored by the monitoring equipment. The table can also be saved to the monitoring equipment's memory or the corresponding database so that users can check the hard drive monitoring status at any time.

[0084] In this invention, the statistical tables generated by the monitoring device can be customized by deleting or adding items as needed, based on actual requirements. For example, if only the number of commands executed and the number of timeouts need to be counted in the aforementioned statistical table, the number of commands executed by the hard drive and the number of timeouts can be directly counted. See Table 2 below:

[0085] serial number Order Execution count Number of timeouts 1 A 3 1 2 B 1 0 3 C 1 1 ... ... ... ...

[0086] Table 2

[0087] For example, when the ratio of timeouts to the total number of commands executed is less than a preset reference value, it indicates that the hard drive's performance is excellent. Therefore, by directly counting the total number of commands executed and the total number of timeouts, the hard drive's performance status can be monitored. Based on the statistical information of the hard drive's command execution, a statistical table can be generated as shown in Table 3 below:

[0088] Total number of times the command was executed Total number of timeouts for executing commands 5 2

[0089] Table 3

[0090] In this invention, a statistical table is generated according to a preset format based on statistical information. The preset format can be set according to actual needs, and this invention does not impose any specific limitations on it.

[0091] In this embodiment, at least one command is sent to the hard drive through a monitoring device; the time information and execution count of each command execution by the hard drive are obtained; the time information includes a first timestamp for each command acquisition and a second timestamp for each command completion; based on the time information and a preset time threshold corresponding to the command, the number of timeouts for command execution is determined; and statistical information of command execution by the hard drive is recorded; the statistical information includes: command information for each command, a first timestamp, a second timestamp corresponding to each command, a preset time threshold, the number of executions, and the number of timeouts. This allows for monitoring of the timeout status of each command execution by the hard drive, without being limited by command attributes, and a more accurate assessment of the hard drive's performance status based on the number of timeouts.

[0092] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
