[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] To ensure efficient and stable operation of the storage system, the storage system uses multipath software to aggregate multiple links. When the business is running normally, multiple links carry the business at the same time, realizing link-level high availability of the storage system. In order to achieve stable operation of the storage system, it is necessary to detect the overall link balance of the storage system. However, there is no method for detecting the overall link balance of the storage system in the prior art, and it is impossible to detect the overall link balance of the storage system.

[0034] In view of this, embodiments of the present application provide a method, apparatus, device and storage medium for determining a multi-link load balance, which can detect the overall link balance of a storage system.

[0035] See also Figure 1 , which shows a schematic diagram of the implementation environment involved in the multi-link load balancing determination method provided in the embodiment of the present application. Figure 1 As shown, the execution subject of the multi-link load balancing determination method provided in the embodiment of the present application can be a computer device or a computer device cluster composed of multiple computer devices. Different computer devices can communicate with each other through wired or wireless methods, and the wireless method can be implemented through WIFI, operator network, NFC (near field communication) or other technologies.

[0036] See also Figure 2 , which shows a flowchart of a multi-link load balancing degree determination method provided by an embodiment of the present application. The multi-link load balancing degree determination method can be applied to Figure 1 In the computer device shown. Figure 2 As shown, the multi-link load balancing determination method may include the following steps:

[0037] Step 201: A computer device calculates a first link balance degree of each controller in a target storage system.

[0038] The target storage system includes multiple controllers, each of which corresponds to multiple links. The controller is used to control the business data in the corresponding link to be stored in the corresponding position in the target storage system; the link is used to carry business data; the link balance is used to characterize the link load balance, that is, to characterize the situation of the link carrying business data; the first link balance of each controller represents the overall balance of the multiple links corresponding to each controller, and the optional popular explanation is: assuming that the target storage system includes n controllers, each controller corresponds to m links, and the first link balance of one controller is the overall balance of the m links corresponding to the controller.

[0039] Step 202: The computer device calculates a second link balance between controllers in the target storage system.

[0040] Among them, the second link balance between controllers is the link balance between controllers in the target storage system. An optional popular explanation is: assuming that the target storage system includes n controllers, each controller corresponds to m links, and the second link balance between the controllers is the link balance between these n controllers.

[0041] Step 203: The computer device calculates the overall link balance of the target storage system according to the first link balances and the second link balances.

[0042] Among them, the overall link balance of the target storage system is the overall load balance of all links in the target storage system. Multiple links are aggregated in the target storage system. When the business is operating normally, multiple links will carry traffic at the same time. If one of the links is sub-healthy or the interface fails, the business data of the link with sub-health or interface failure will be blocked. At the same time, the business data of the healthy link will be blocked, thereby affecting the overall performance of the target storage system. It is worth noting that if one of the links is sub-healthy or the interface fails, the overall link balance of the target storage system will be reduced. In other words, the overall link balance of the target storage system can reflect the health of the links in the target storage system. Therefore, in order to ensure the stable operation of the target storage system, it is necessary to detect the overall link balance of the target storage system.

[0043] In an embodiment of the present application, a method for calculating the overall link balance of a target storage system is provided. The method calculates the overall link balance of the target storage system based on the calculated first link balance of each controller and the second link balance between the controllers, thereby realizing the detection of the overall link balance of the target storage system.

[0044] In one embodiment of the present application, a computer device calculates the first link balance of each controller in a target storage system, and the optional process is as follows:

[0045] First, the computer device obtains ownership information corresponding to each link in the target storage system.

[0046] The belonging information is used to indicate the controller to which the corresponding link belongs; the belonging information may be link parameter information corresponding to each link.

[0047] Secondly, the computer device determines the link corresponding to each controller according to the acquired ownership information.

[0048] Thirdly, for each controller, the computer device obtains performance indicator data of each link corresponding to the controller.

[0049] Optionally, assuming that there are n controllers in the target storage system, and each controller corresponds to m links, the performance indicator corresponding to each link is I k .

[0050] Finally, the computer device calculates the first link balance of each controller according to the performance indicator data. Optionally, assuming that there are n controllers in the target storage system, each controller corresponds to m links, and the optional formula for calculating the first link balance is as follows:

[0051]

[0052] in,

[0053]

[0054] Among them, B i I represents the first link balance of one of the n controllers, i=1, 2, ....n; k Indicates the performance indicator corresponding to one of the m links.

[0055] In one embodiment of the present application, based on the first link balance of each controller, the second link balance between the controllers can be obtained. Optionally, assuming that there are n controllers in the target storage system, each controller corresponds to m links, and the optional formula for calculating the second link balance is as follows:

[0056]

[0057] in,

[0058]

[0059] Among them, B i represents the first link balance of one of the n controllers, i=1, 2, ....n; B represents the second link balance between the controllers.

[0060] Traditional link detection methods mainly rely on manual labor, and through manual observation of the monitoring interface, such methods can only perform qualitative analysis of link balance, but cannot perform quantitative calculation. In addition, if the number of links is large, the manual operation of the monitoring interface will also increase, increasing the risk of manual misoperation. In the embodiment of the present application, the link balance can be quantitatively calculated through the first link balance and the second link balance, and no manual participation is required in the process of calculating the link balance. Therefore, the quantitative calculation of the link balance in the embodiment of the present application improves the intelligence and accuracy of link balance detection.

[0061] See also Figure 3 , which shows a technical process for calculating the overall link balance of a target storage system provided by an embodiment of the present application. Figure 3 As shown, the calculation of the overall link balance may include the following steps:

[0062] Step 301: Obtain weight values ​​corresponding to the first link balances and the weight values ​​corresponding to the second link balances.

[0063] The optional process of obtaining the weight values ​​corresponding to the first link balances and the weight values ​​corresponding to the second link balances is as follows:

[0064] First, the computer device obtains the carrying storage capacity of each controller and the load balancing mode of each controller.

[0065] Optionally, the computer device may determine the balancing mode of each controller according to the parameter information of each controller, wherein, according to the design concepts of different manufacturers, the load balancing modes of the controllers in the target storage system include active / passive mode (AP), asynchronous logical unit access mode (ALUA), and active / active mode (AA). In the AP mode, the port on one controller is in an active state, the port on the other controller is in a standby state, and all logical unit numbers (LUNs) belong to the controller in the active port state; for a single LUN, when carrying services normally, only half of the links have traffic at a certain moment. In the ALUA mode, the ports on both controllers are in an active state, but different LUNs belong to different controllers; for a single LUN, when carrying services normally, only half of the links have traffic at a certain moment. In the AA mode, the ports on both controllers are in an active state, and there is no LUN belonging; for a single LUN, when carrying services normally, all links have traffic.

[0066] Secondly, according to each of the bearing storage capacities and each of the load balancing modes, the weight values ​​corresponding to each of the first link balance degrees and the weight value corresponding to the second link balance degrees are determined.

[0067] Optionally, when the load balancing mode of the controller is AP mode, it is recommended that the first link balance of each controller use a lower weight value; when the load balancing mode of the controller is AA mode, it is recommended that the second link balance between controllers use a lower weight value.

[0068] Step 302: Perform weighted sum processing on the first link balance and the second link balance according to the acquired weight value to calculate the overall link balance of the target storage system.

[0069] Optionally, the calculation formula for calculating the overall link balance of the target storage system by weighted summation is as follows:

[0070]

[0071] Among them, λ i are the weight values ​​corresponding to the first link balance respectively; 0 is the weight value corresponding to the balance degree of the second link; B irepresents the first link balance of one of the n controllers, i=1, 2, ....n; B is the second link balance between the controllers, and P is the overall link balance of the target storage system.

[0072] In the embodiment of the present application, the value of the overall link balance degree P of the target storage system is between 0 and 1. If the value of P is closer to 1, the overall link of the target storage system is more balanced; conversely, if the value of P is closer to 0, the overall link of the target storage system is more unbalanced. In the embodiment of the present application, by calculating the overall link balance degree of the target storage system, the accurate detection of the overall link balance degree of the target storage system is achieved.

[0073] In one embodiment of the present application, if the overall link balance of the target storage system is less than a first threshold, the link load balancing algorithm of the target storage system is adjusted by a computer device; if the overall link balance of the target storage system is less than a second threshold, the most abnormal link is isolated by a computer device; wherein the second threshold is less than the first threshold.

[0074] Optionally, the first threshold is 70% of the overall link balance of the target storage system under normal operation, and the second threshold is 30% of the overall link balance of the target storage system under normal operation.

[0075] In an optional embodiment of the present application, when the overall link balance of the target storage system is lower than the first threshold, the target storage system will dynamically adjust the link load balancing algorithm in combination with the business situation. Among them, each load balancing mode of the controller includes multiple link load balancing algorithms, such as a polling algorithm, a shortest path algorithm, etc. Optionally, when the overall link balance of the target storage system is lower than the first threshold, the target storage system can adaptively adjust the link load balancing parameters in combination with the production environment application scenario, and dynamically adjust the load balancing algorithm in combination with the balancing algorithm of the target storage system (such as adjusting the shortest path algorithm to a polling algorithm), and after adjusting the load balancing algorithm, continue to detect the overall link balance of the target storage system.

[0076] Optionally, after adjusting the link load balancing algorithm as described above, if the overall link balance of the target storage system is still decreasing, and the overall link balance is lower than the second threshold, then the target storage system will actively isolate the most abnormal link with the largest balance deviation based on the performance indicator data of each link, and notify the operation and maintenance personnel to conduct manual investigation, consider the possible sub-health of the physical link, and replace the physical optical fiber, optical module or board in time.

[0077] In the related art, the link load balancing situation is mainly observed manually. When the monitoring interface shows that the target storage system has storage anomalies, the abnormal links are manually checked. That is to say, before the abnormal links are manually checked, the target storage system does not dynamically adjust the link load balancing algorithm in combination with the business situation, nor does it actively isolate the most abnormal links. It can be seen that the target storage system in the related art cannot accurately judge the overall link balance in advance, so that the target storage system has a weak ability to deal with the sub-health risk of the physical link. In the embodiment of the present application, when the overall link balance of the target storage system is less than the first threshold, the link load balancing parameters are adaptively adjusted in combination with the production environment application scenario, and the load balancing algorithm is dynamically adjusted in combination with the balance algorithm of the target storage system, so as to ensure the smooth operation of the target storage system; when the overall link balance of the target storage system is less than the second threshold, the target storage system will actively isolate the most abnormal link with the largest balance deviation, so as to ensure the efficient operation of the target storage system. Therefore, the target storage system in the embodiment of the present application has a strong ability to deal with the sub-health risk of the physical link.

[0078] See also Figure 4 , which shows a flowchart of a multi-link load balancing degree determination method provided by an embodiment of the present application. The multi-link load balancing degree determination method can be applied to Figure 1 In the computer device shown. Figure 4 As shown, the multi-link load balancing determination method may include the following steps:

[0079] Step 401: The computer device obtains ownership information corresponding to each link in the target storage system.

[0080] Step 402: The computer device determines the link corresponding to the controller according to the acquired ownership information.

[0081] Step 403: The computer device obtains performance indicator data of each link corresponding to each controller.

[0082] Step 404: The computer device calculates the first link balance of each controller according to the performance indicator data of each link corresponding to each controller.

[0083] Step 405: The computer device calculates the second link balance between the controllers according to the first link balance of each controller.

[0084] Step 406: The computer device obtains the weight values ​​corresponding to the first link balances and the weight values ​​corresponding to the second link balances.

[0085] Step 407: The computer device performs weighted sum processing on the first link balance degree and the second link balance degree according to the acquired weight value, and calculates the overall link balance degree of the target storage system.

[0086] In an optional embodiment of the present application, a schematic diagram of a link balance detection system is provided. For the schematic diagram of the link balance detection system, please refer to Figure 5 ,like Figure 5 As shown, the link balance detection system includes a production environment storage system and a link load balancing detection system.

[0087] The link load balancing detection system includes an information preprocessing module and a data analysis module. The information preprocessing module is used to determine the balancing mode of each controller and the controller to which each link belongs. The data analysis module is used to calculate the balance within the controller and the balance between controllers. The balance within the controller is the balance of the first link of the controller, and the balance between controllers is the balance of the second link between controllers. Optionally, the optional operation process of the link balance detection system is:

[0088] First, the production environment storage system inputs the stored storage system parameter information into the information preprocessing module in the link load balancing detection system, wherein the storage system parameter information may be the attribution information corresponding to each link and the parameter information of each controller.

[0089] Second, the information preprocessing module outputs the controller balancing mode and the controller to which the link belongs. The information preprocessing module can determine the balancing mode of each controller based on the parameter information of each controller. At the same time, the information preprocessing module can also determine the link corresponding to each controller based on the belonging information corresponding to each link. In other words, the information preprocessing module can determine the controller to which the link belongs.

[0090] Third, the controller balancing mode and the controller to which the link belongs are input into the data analysis module.

[0091] Fourth, the data analysis module outputs the intra-controller balance and the inter-controller balance according to the controller balance mode and the controller to which the link belongs.

[0092] Fifth, the link load balancing detection system calculates the link balance degree according to the balance degree within the controller and the balance degree between controllers, wherein the link balance degree is the overall link balance degree of the target storage system.

[0093] In another optional embodiment of the present application, taking four controllers as an example, the corresponding weight values ​​of the four controllers in different load balancing modes are recommended as follows:

[0094]

[0095] Among them, SP1, SP2, SP3, and SP4 represent controllers, B1-B4 are the first link balances corresponding to controllers SP1-SP4, B is the second link balance between the four controllers SP1-SP4, and the link balance is the overall link balance of the target storage system composed of these four controllers. According to the calculation formula for the overall link balance of the target storage system in the previous text, the overall link balance of the target storage system under different load balancing modes can be obtained.

[0096] It should be understood that, although the various steps in the flow chart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
