[0023] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with 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.

[0024] With the rapid development of the Internet, the growth of large models and AI has been particularly significant in recent years. In view of this, the demand for data has increased, and the application scenarios of storage arrays for data storage have become more widespread.

[0025] The security and reliability of data storage are one of the key indicators for measuring the performance of a storage array. As described earlier, the CLI is a user interface provided by the storage array to manage and maintain itself. Due to the mutual influence of many CLI operation objects, concurrent CLI operations can easily cause data inconsistency. To ensure data consistency, many CLIs need to be executed serially, and even in some storage arrays all CLIs must be executed serially. However, CLI serialization will inevitably affect its response speed, and the management device of the storage array is used to operate the storage array through the CLI, thereby affecting the response speed of both the storage array and the management device.

[0026] To solve the technical problem of storage array response delay in the related art, the present application provides a storage array management method, a storage array management device, a storage array and a computer readable storage medium. The storage array management method comprises: obtaining a command line interface to be executed in the storage array; wherein the number of the command line interface to be executed is one or more; identifying the command line attribute of the command line interface respectively, matching the execution priority associated with the command line attribute of each command line interface; wherein the preconfigured execution priority associated relationship of each command line attribute; and executing the command line interface in turn according to the priority order. The specific working principle of the present application is described by example.

[0027] Please refer to Figure 1 , Figure 1 is a flowchart of an embodiment of the storage array management method of the present application.

[0028] S101: obtaining a command line interface to be executed in the storage array; wherein the number of the command line interface to be executed is one or more.

[0029] In this embodiment, the command line interface represents a visual prompt interface provided by the storage array and / or the storage array management device for the user. When using the command line interface, the command can be input in a specific line to receive data such as response command line interface from the storage array and / or the storage array management device.

[0030] S102: identifying the command line attribute of the command line interface respectively, matching the execution priority associated with the command line attribute of each command line interface; wherein the preconfigured execution priority associated relationship of each command line attribute.

[0031] In this embodiment, the command line attribute is used to represent the role, request, function, etc. of the command line interface. The execution priority can be used to represent the urgency of the execution of the command line interface.

[0032] In this embodiment, the execution priority is associated with several kinds of command line attributes respectively. The command line interface with high execution priority can be executed relatively before the command line interface with low execution priority. Optionally, two levels of execution priority, three levels of execution priority, four levels of execution priority, etc. can be pre-planned to reduce the burden of excessive grading while planning multiple execution priorities.

[0033] As such, when the command line interface to be executed is obtained, the command line attribute of the command line interface can be identified. In response to obtaining the command line attribute of the command line interface, the execution priority matching the command line attribute is obtained to identify the execution priority degree of the command line interface to be executed by using the execution priority.

[0034] S103: execute the command line interfaces in turn according to the priority order.

[0035] In the embodiment, the command line interfaces are executed in turn according to the priority order in response to completion of the execution priority identification of the command line interfaces to be executed.

[0036] For example, in the embodiment, the execution priority comparison can be performed again on all the command line interfaces to be executed when a new command line interface such as a real-time access request is obtained; or, the execution priority evaluation can be performed only on the newly obtained command line interface to be executed; or, the execution priority evaluation can be performed on part of the previously existing command line interfaces to be executed and the newly obtained command line interface to be executed, which is not limited herein.

[0037] In this way, the execution priority of the command line interfaces to be executed in the storage array is determined in the embodiment. That is, the command line attributes of the command line interfaces can be pre-associated with the execution priorities, so that the execution priorities of the command line interfaces are matched based on the command line attributes of the command line interfaces, the command line interfaces are executed according to the priority order, the cache of the management device of the storage array is dynamically adjusted, the resources are inclined to the command line interfaces with high urgency, and even the response and implementation of the high urgency demand can be guaranteed even if the resources are insufficient, so that the execution efficiency of the command line interfaces with high response efficiency requirements is improved by optimizing the corresponding strategies of the command line interfaces, and the performance of the management device is improved.

[0038] Please refer to Figure 2 , Figure 2 is a flowchart of another embodiment of the management method of the storage array. It should be noted that the first priority, the second priority, and the third priority are taken as examples for illustration in the embodiment. The priority levels of the first priority, the second priority, and the third priority are gradually reduced, and in a popular way, the priority level of the first priority is the highest, and the command line interface of the first priority can be executed preferentially.

[0039] S201: obtain a command line interface to be executed.

[0040] S202: identify a command line attribute of the command line interface.

[0041] S203: the command line attribute of the command line interface is a real-time request attribute, and the execution priority of the command line interface is determined as the first priority.

[0042] In the embodiment, in response to the command line interface being associated with a real-time access request of the storage array, the command line attribute of the command line interface is determined as the real-time request attribute, and the first priority associated with the real-time request attribute is taken as the execution priority of the command line interface.

[0043] That is, in the embodiment, the real-time access request of the user is configured as the highest priority, and the command line interface of the real-time access request is executed preferentially, so that the real-time access request of the user can be responded in time, and the response efficiency can be improved, so that the user can obtain the expected data in a relatively short waiting time.

[0044] S204: The command line attribute of the command line interface is a display attribute, and it is determined that the execution priority of the command line interface is a second priority.

[0045] In the embodiment, in response to the fact that the command line interface needs to display the current page for the management device of the storage array, it is determined that the command line attribute of the command line interface is a display attribute, and the second priority associated with the display attribute is taken as the execution priority of the command line interface. In this way, the current page can be displayed in time and completely, and the loading speed of the current page can be improved. That is, in the embodiment, the loading speed of the current page can be improved while ensuring the response efficiency to the user request, so that the current page can be loaded and displayed in a relatively short time, and the time for the user to wait for the loading of the current page is reduced, thereby significantly improving the user experience by reasonably planning the priority levels.

[0046] In other words, the real-time request attribute and the display attribute can be configured to have a higher priority level than other attributes, so as to improve the response efficiency of the instant interaction with the user. At the same time, the command line interface configured with the real-time request attribute and the display attribute can be input into an execution queue with a corresponding execution priority, and the execution is performed in turn according to the time of the command line interface entering the queue, that is, according to the order of obtaining the command line interface.

[0047] S205: The command line attribute of the command line interface is another attribute, and it is determined that the execution priority of the command line interface is a third priority.

[0048] In the embodiment, the command line attribute of the command line interface can be identified as another attribute, and it is determined that the command line interface is of the third priority; wherein the other attribute represents a non-display attribute and a non-real-time request attribute.

[0049] S206: The priority scores of the command line interfaces of the third priority are evaluated, and the execution orders of the command line interfaces of the third priority are sorted based on the priority scores.

[0050] In the embodiment, the priority scores of the command line interfaces of the third priority can be evaluated respectively. Based on the priority scores, the execution orders of the command line interfaces of the third priority are sorted.

[0051] That is, the queuing manner of the command line interface of other attributes in the embodiment can be distinguished from the queuing manner of the command line interface with higher priority. The priority scores of the command line interfaces of other attributes to be executed are respectively evaluated to sort the command line interfaces based on the priority scores, so that the execution order of the command line interfaces can be planned in combination with the scoring mechanism, the command line interfaces with higher priority scores can be preferentially executed, and the rationality of the execution order planning of the command line interfaces is further improved.

[0052] In an alternative embodiment, the command line interfaces of each execution priority can also be queued according to the acquisition time, or the command line interfaces of each execution priority can be queued according to the evaluated priority scores, and other queuing manners will not be described here

[0053] Specifically, the command line interface to be evaluated for the priority score can be regarded as a command line to be evaluated. It is judged whether the command line to be evaluated is associated with a management instruction; wherein the management instruction is used to operate the current page.

[0054] In response to the command line to be evaluated being associated with the management instruction, the command line to be evaluated is given a first score factor.

[0055] In response to the command line to be evaluated being associated with the command line interface of the second priority, the command line to be evaluated is given a second score factor. For example, object X is generated (or composed) by object Y, or object X can generate or compose or be applied to object Z, then objects Y and Z are called associated objects of object X, and the command line interfaces of objects Y and Z can be called associated command line interfaces of the command line interfaces of object X. For example, the associated command line interfaces of the command line interfaces of the query pool are the command line interfaces of the query RAID, volume and file system, and the associated command line interfaces of the command line interfaces of the query volume are the command line interfaces of the query pool, host, snapshot, mirror and remote replication. The objects in different storage arrays are not the same, and the relationships between the objects are not the same, so the specific association relationship will not be described here.

[0056] The command line to be evaluated is given a third score factor or a fourth score factor based on the exception prompt level. For example, when being in a lower exception prompt level, the third score factor is given; when being in a higher exception prompt level, the fourth score factor is given. The score value of the third score factor is lower than that of the fourth score factor, so that the command line interface with higher exception risk is preferentially executed.

[0057] The command line to be evaluated is given a fifth score factor based on the access habit.

[0058] The score factors obtained by the command line to be evaluated are fused as the priority score. The score factors include a first score factor, a second score factor, a third score factor, a fourth score factor, and a fifth score factor. Alternatively, the score factors can be superimposed, or can be fused by weighting, or can take the maximum value, which is not limited herein.

[0059] Alternatively, at least one of the first score factor, the second score factor, the third score factor, the fourth score factor, and the fifth score factor can be an experience value, or a value calculated by a machine learning algorithm according to historical data, which is not limited herein.

[0060] Therefore, when evaluating the priority score of the command line interface, the relevance of the storage array object, the access habits of the user, and other factors can be comprehensively considered to improve the rationality of the priority score calculation method, and the user habits can be adapted to further improve the response efficiency of the storage array to the information concerned by the user.

[0061] Alternatively, when evaluating the fifth score factor, the multi-level associated access frequencies of the command line to be evaluated and the current page can be obtained respectively. The access frequency scores of each level are fused by weighting. The access frequency score represents the fitting value of the associated access frequency and the extreme value of the fifth score factor. The N-level associated access frequency is the ratio of the first number to the second number. The first number represents the number of times of switching N times from the current page to the associated page of the command line to be evaluated; and the second number represents the number of times of switching N times from the current page to any page.

[0062] For example, the N-level associated access frequency can be the number of times of switching N times from page A (i.e., the current page) to page B divided by the total number of times of switching N times from page A to any page (including page A and page B).

[0063] Further, the weighting factors of different levels of access frequency scores can be different, and the weighting factor of the access frequency level with fewer switching times can be higher.

[0064] For example, the calculation formula of the fifth evaluation factor can be as shown in the following example:

[0065] S5 = F1 * S5 max * 4 / 7 + F2 * S5 max * 4 / 7 + F3 * S5 max * 1 / 7

[0066] Wherein, F1 represents the first-level associated access frequency, F2 represents the second-level associated access frequency, and F3 represents the third-level associated access frequency; S5 represents the fifth evaluation factor, S5 maxThis represents the maximum value of the fifth evaluation factor; 4 / 7, 4 / 7, and 1 / 7 represent the weighting factors for the access frequency scores of the first-level association access frequency, the second-level association access frequency, and the third-level association access frequency, respectively.

[0067] Please see Figure 3 , Figure 3 This is a flowchart illustrating an embodiment of updating the execution priority in this application.

[0068] S301: Evaluate the execution priority of each command-line interface.

[0069] In this embodiment, the execution priority of each command-line interface to be executed can be evaluated to form command-line sets corresponding to each execution priority. The command-line interface to be adjusted is then moved into an execution queue that matches its current execution priority. In this embodiment, the command-line interface to be adjusted refers to a command-line interface whose current command-line set priority is higher than the priority of its execution queue priority.

[0070] In this way, the execution priority of each command-line interface can be updated so that the execution priority assigned to the command-line interface adapts to the real-time situation of the storage array. For command-line interfaces that should currently belong to relatively high priority but are actually in a low priority, the priority can be adjusted, thereby shortening their queuing time and speeding up their execution.

[0071] S302: Update the execution queue with the highest priority.

[0072] In this embodiment, the command-line interface can be moved into an execution queue that matches the currently evaluated execution priority based on the execution priority evaluated for each command-line interface.

[0073] This means that command-line interfaces evaluated as having the highest priority can be written into the execution queue corresponding to the highest priority.

[0074] S303: Update the second priority execution queue.

[0075] In this embodiment, command-line interfaces evaluated as having the second priority can be written into the execution queue corresponding to the second priority.

[0076] S304: Update the execution queue of the third priority.

[0077] In this embodiment, command-line interfaces evaluated as having the third priority can be written into the execution queue corresponding to the third priority.

[0078] For example, based on the execution priority of all command-line interfaces of the currently acquired real-time access requests, high, medium, and low priority command-line interfaces can be designed and formed into high, medium, and low priority sets Set1, Set2, and Set3, respectively.

[0079] The command line interfaces in the low priority queue in Set 1 can be moved to the high priority queue in the order of the time when the command line interfaces are initially queued. The command line interfaces in the low priority queue in Set 2 can be moved to the secondary priority queue in the order of the time when the command line interfaces are initially queued. The command line interfaces in the high priority queue in Set 2 remain in the high priority queue because these command line interfaces are previously determined to require high priority execution, but they are still in the queue, indicating that the previous high priority task has not been completed and the high priority needs to be maintained. The command line interfaces in the low priority queue in Set 3 can be re-queued in the low priority queue in the order of the latest score from high to low. The command line interfaces in the high and secondary priority queues in Set 3 remain in the queues.

[0080] Optionally, when the execution queues of each execution priority are updated in the embodiment, the command line interfaces of each changed execution priority can be further screened. When the execution priority of a command line interface is reduced after re-evaluation, the command line interface can be processed without being discarded in the execution queue of the original execution priority. When the execution priority of a command line interface is increased after re-evaluation, the command line interface can be migrated to the execution queue of the re-evaluated execution priority.

[0081] Further, at a time point such as obtaining a new to-be-executed command line interface, when a to-be-executed command line interface is written to the execution queue of the lowest priority for queuing, the scores of all command line interfaces belonging to the execution queue of the lowest priority can be re-evaluated, i.e., the command line interfaces in the execution queue are dequeued, and the priority scores are re-evaluated, and the command line interfaces are re-queued according to the re-evaluated priority scores, so as to adjust the execution order of the command line interfaces.

[0082] Further, in the embodiment, the queuing time of the command line interface in the execution queue of the current priority can be obtained. In response to the queuing time reaching the time threshold of the current priority, the execution priority of the command line interface is increased, and the command line interface is migrated to the execution queue of the increased execution priority. The time thresholds of each execution priority can be the same or different, which can be determined according to the actual business scenario, and is not limited herein. In this way, the risk that the command line interface is in the execution queue of the relatively low priority for a long time and is not executed for a long time can be reduced, so that other command line interfaces can be reasonably executed while the response efficiency of the storage array and the management device thereof is ensured, and the rationality of the command line interface execution strategy in the embodiment is further improved.

[0083] Please refer to Figure 4 , Figure 4is a flowchart of an embodiment of the command line interface entry execution queue of the present application. The working principle of adding a new command line interface to the queue when the command line interface data changes is described by way of example in this embodiment.

[0084] S401: Classify the command lines to be adjusted.

[0085] In this embodiment, the command lines to be adjusted can be classified based on the priority to which they belong.

[0086] S402: Write the command lines to be adjusted to the first priority into the execution queue of the first priority, and write the command lines to be adjusted to the second priority into the execution queue of the second priority.

[0087] In this embodiment, if the high-priority and low-priority command line interfaces are already in the corresponding queues, they do not need to be added again, which can reduce the processing of the command line interfaces and save time. If the high-priority command line interface of this time is in the low-priority queue, the command line interface is moved to the high-priority queue; if the low-priority command line interface of this time is in the low-priority queue, the command line interface is moved to the low-priority queue.

[0088] S403: Sort the command lines to be adjusted to the third priority according to the priority score, and write them into the execution queue of the third priority in order.

[0089] Please refer to Figure 5 , Figure 5 is a flowchart of an embodiment of the real-time access request processing of the present application.

[0090] S501: Obtain a real-time access request.

[0091] In this embodiment, the management device can obtain the real-time access request from, for example, a webpage, an applet, etc.

[0092] S502: Determine whether the command line interface corresponding to the real-time access request is in the execution queue of the first priority.

[0093] S503: Wait for the command line interfaces in the execution queue of the first priority to be executed in turn until the command line interface corresponding to the real-time access request is executed.

[0094] S504: Obtain the data required by the command line interface from the cache of the management device of the storage device.

[0095] S505: Assemble the response data and respond to the real-time access request.

[0096] It should be understood that, although Figures 1 to 5The steps in the flowchart are shown in sequence according to the arrows, but the steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, the steps are not strictly limited in sequence, and the steps can be executed in other sequences. Moreover, Figures 1 to 5 At least one of the steps in the flowchart can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of the sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with other steps or at least one of the sub-steps or stages of other steps.

[0098] In an embodiment, the storage array management device can include an obtaining module and a management module.

[0099] The storage array management device is connected to the storage array body.

[0100] Referring to Figure 7 , Figure 7 is a structural schematic diagram of an embodiment of the storage array management device.

[0101] In an embodiment, the storage array management device can include an obtaining module and a management module.

[0102] The obtaining module is configured to obtain the command line interfaces to be executed.

[0103] The management module is connected to the obtaining module to implement the storage array management method according to any one of the above. That is, the management module can be configured to obtain the command line interfaces to be executed in the storage array; wherein the number of the command line interfaces to be executed is one or more. The command line attributes of the command line interfaces are identified respectively, and the execution priorities associated with the command line attributes are matched for the command line interfaces; wherein the preconfigured association relationship between the command line attributes and the execution priorities. The command line interfaces are executed in sequence according to the priority order.

[0104] As such, the execution priority of the command line interface to be executed in the storage array is determined in the embodiment. That is, the command line attribute of the command line interface can be pre-associated with the execution priority, so as to match the execution priority of the command line interface based on the command line attribute of the command line interface, execute the command line interface in the order of priority, and dynamically adjust the cache of the management device of the storage array, so as to improve the execution efficiency of the command line interface with higher response efficiency requirement by optimizing the corresponding strategy of the command line interface, and further improve the performance of the management device.

[0105] The specific definition of the management device of the storage array can refer to the definition of the management method of the storage array in the foregoing, and will not be described here.
