Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data centers, in particular to a method and device for detecting error codes of a data transmission link and an electronic device. BACKGROUND

[0002] A data transmission link is a physical path for transmitting data in a data communication system and is a medium for transmitting data from a sending end to a receiving end. In actual use, errors may occur when the data transmission link transmits data, thereby generating error codes. In the related art, when the error codes of the data transmission link reach an error code threshold, the data transmission link is actively disconnected for fault isolation.

[0003] However, for devices connected by the data transmission link, especially for devices that need to run for a long time, if the error code threshold is too low, the cumulative error code count may gradually exceed the error code count threshold, triggering unnecessary link disconnection; conversely, if the error code count threshold is too high, the situation of rapid growth of error codes in a short period of time may not be discovered and responded to in time, resulting in ineffective fault isolation.

[0031] Figure 4 A structural schematic diagram of an electronic device provided by an embodiment of the present application is shown. DETAILED DESCRIPTION

[0032] Embodiments of the present application are described in detail below with reference to examples shown in the attached drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0033] Specifically, Figure 1 A flowchart of a method for error code detection of a data transmission link provided by an embodiment of the present application is shown.

[0034] As Figure 1 shown, the method for error code detection of the data transmission link includes the following steps:

[0035] In step S101, multiple running scenarios of the data transmission link are determined.

[0036] It can be understood that the running scenarios can include multiple types, such as a short-period running scenario and a long-period running scenario. In the short-period running scenario, there can be a rapid growth of error codes. In the long-period running scenario, the device needs to run for a long time. Those skilled in the art can set the running scenarios according to actual conditions. For example, a long-period running scenario can be set between the short-period running scenario and the long-period running scenario to enrich the running scenarios and increase the personalized needs of error code detection of the data transmission link.

[0037] In some embodiments, the types of the data transmission link can include many types, such as a wired transmission link and a wireless transmission link. The wired transmission link can be, for example, a twisted pair, a coaxial cable, an optical fiber, etc. The wireless transmission link can be, for example, Bluetooth, infrared, radio waves, etc. Taking SAS as an example, SAS can be used for data transmission between an upper-layer device and a lower-layer device. The upper-layer device can be, for example, a CPU or a host, etc. The lower-layer device can be, for example, a storage device, etc.

[0038] In some embodiments, the data transmission link can include an uplink port and a downlink port. The uplink port is connected to a port of the upper-layer device and is used to transmit data from the lower-layer device to a processing unit of the upper-layer device. The downlink port is connected to a port of the lower-layer device and is used to deliver data from the upper-layer device to the lower-layer device.

[0039] Therefore, the execution subject of the method in the embodiment of the present application is an electronic device. The electronic device can be the upper-layer device and the lower-layer device described above, or other devices that can run the program corresponding to the method, such as deploying the program of the method in the embodiment of the present application on the corresponding device. The program can be deployed on the upper-layer device or the lower-layer device alone, or can be deployed on the upper-layer device and the lower-layer device simultaneously, so as to implement the error code detection of the data transmission link.

[0040] In step S102, a plurality of error code counting periods and corresponding error code counting thresholds are set according to a plurality of running scenarios.

[0041] It should be noted that the error code counting periods required by different running scenarios are different. For example, in a short-period running scenario, there can be a situation of rapid growth of error codes. In order to monitor the situation of rapid growth of error codes, a shorter error code counting period, such as 1 minute, 2 minutes or 3 minutes, etc., is set in the embodiment of the present application to achieve rapid error code detection. For another example, in a long-period running scenario, the device needs to run for a long time. If a shorter error code counting period is set, the interruption of the data transmission link is easily triggered, which affects the normal operation of the device and does not meet the use requirements of the user. Therefore, a longer error code counting period, such as 12 hours, 13 hours or 14 hours, etc., is set in the embodiment of the present application to ensure the stable operation of the device while monitoring the error codes.

[0042] It is just because that the error code counting periods required by different running scenarios are different, the error code counting thresholds required by different running scenarios are also different. The embodiment of the present application sets different error code counting thresholds for different running scenarios. The error code counting threshold of the short-period running scenario can be set to 10 times, 11 times or 12 times, etc. A smaller error code counting threshold is set to timely discover and respond to the situation of rapid growth of error codes in a short period. The error code counting threshold of the long-period running scenario can be set to 30 times, 31 times or 32 times, etc. A larger error code counting threshold is set to avoid unnecessary disconnection of the data transmission link.

[0043] Therefore, the embodiment of the present application adopts different error code counting thresholds in different running scenarios to avoid the inapplicable problem caused by sharing the error code counting threshold. While ensuring the accuracy of error code detection, the applicability of error code detection of the data transmission link can be effectively improved. The different error code detection requirements in different running scenarios are effectively taken into account, and the use experience of the user is improved.

[0044] For ease of description, in the following embodiments, the error code counting period in the short-period running scenario is a short error code counting period, and the error code counting period in the long-period running scenario is a long error code counting period.

[0045] In some embodiments, the embodiments of the present application not only set multiple error code counting periods based on multiple running scenarios, but also set multiple error code counting periods based on uplink and downlink.

[0046] It can be understood that, since the uplink and the downlink are in actual operation, the uplink carries data streams converged from multiple lower-layer devices, and the data transmission amount is larger and more complex, and the downlink is responsible for distributing data to specific lower-layer devices, and the data transmission amount is relatively stable, so the error code detection requirements of the uplink and the downlink are different, and the embodiments of the present application can set different error code counting periods for different data transmission amounts of the uplink and the downlink, effectively meet the actual error code detection requirements, and improve the applicability of error code detection.

[0047] For example, a short error code counting period and a long error code counting period are set for the uplink and the downlink, respectively, for example, the short error code counting period of the uplink is set to 1 minute, the long error code counting period is set to 12 hours, the short error code counting period of the downlink is set to 2 minutes, and the long error code counting period is set to 6 hours.

[0048] In step S103, the error code count of the data transmission link is obtained within the error code counting period, and based on the error code counts corresponding to the multiple error code counting periods and the error code count thresholds, the error code detection results of the data transmission link in multiple running scenarios are determined.

[0049] The error code detection results in multiple running scenarios include detection results in a long-period running scenario and detection results in a short-period running scenario.

[0050] It can be understood that, the embodiments of the present application can obtain the error code count of the data transmission link within the error code counting period, and based on the error code counts corresponding to the multiple error code counting periods and the error code count thresholds, the error code detection results of the data transmission link in multiple running scenarios are determined, which comprehensively considers the error code characteristics, user's use requirements and other aspects, sets different error code counting periods and error code count thresholds for different running scenarios, avoids the inapplicable problem caused by sharing the error code count threshold, ensures the accuracy of error code detection, effectively improves the applicability of error code detection of the data transmission link, effectively takes into account different error code detection requirements in different running scenarios, and improves the user's use experience.

[0051] In the embodiments of the present application, based on the error code counts corresponding to the multiple error code counting periods and the error code count thresholds, the error code detection results of the data transmission link in multiple running scenarios are determined, including: within the error code counting period corresponding to the multiple running scenarios, calculating the counting difference value between the current error code count and the last error code count, and generating the error code detection result according to the counting difference value and the error code count threshold.

[0052] It can be understood that the application can calculate the count difference between the current error code count and the last error code count in the error code count period corresponding to multiple running scenarios, and then generate an error code detection result according to the count difference and the error code threshold. The error code detection result is obtained by comparing the pre-set error code count threshold with the calculated count difference, thereby improving the accuracy of the error code detection result.

[0053] Specifically, the embodiment of the application can read the error code counts of the uplink and downlink in different error code count periods at a preset interval (such as 10 seconds), and generate an error code detection result according to the count difference between the current error code count and the last error code count, and the error code count threshold.

[0054] In the embodiment of the application, generating the error code detection result according to the count difference and the error code count threshold includes: accumulating the count difference in the error code count period; and generating the error code detection result according to the accumulated value of the count difference and the error code count threshold.

[0055] It can be understood that the embodiment of the application can accumulate the count difference in the error code count period, and generate the error code detection result according to the accumulated value of the count difference and the error code count threshold.

[0056] In the embodiment of the application, generating the error code detection result according to the accumulated value of the count difference and the error code count threshold includes: if the accumulated value of the count difference is greater than the error code count threshold, determining that the error code detection result is that the data transmission link has a fault; and if the accumulated value of the count difference is less than or equal to the error code count threshold, determining that the error code detection result is that the data transmission link has no fault.

[0057] The error code count threshold is a count threshold set in advance according to specific conditions, which is not specifically limited, such as 5 times or 6 times for the error code count threshold of the uplink error code count period, and 25 times or 30 times for the error code count threshold of the long error code count period.

[0058] It can be understood that the embodiment of the application determines that the error code detection result is that the data transmission link has a fault when the accumulated value of the count difference is greater than the error code count threshold, and otherwise determines that the error code detection result is that the data transmission link has no fault. By comparing the accumulated error code count difference in different error code count periods with the error code count threshold, it is more accurate to determine whether the data transmission link has a fault, thereby avoiding frequent reading and processing of unnecessary error code information.

[0059] It should be noted that the embodiment of the application reports an alarm event of too many error codes of the data transmission link after determining that the error code detection result is that the data transmission link has a fault, and disconnects the data transmission link.

[0060] In the embodiment of the present application, after determining that the error code detection result is that the data transmission link does not have a fault, the method further comprises: determining an error code counting basis of a next error code counting period according to the accumulated value of the counting difference value, and entering the next error code counting period of the data transmission link.

[0061] It can be understood that the embodiment of the present application can determine the error code counting basis of the next error code counting period according to the accumulated value of the counting difference value, and enter an error code counting period of the data transmission link, and dynamically adjust the error code counting basis of the next error code counting period through the accumulated value of the counting difference value, so as to flexibly adapt to the change of the error code, thereby improving the accuracy of error code detection.

[0062] In the embodiment of the present application, determining the error code counting basis of the next error code counting period according to the accumulated value of the counting difference value comprises: determining whether the accumulated value of the counting difference value is greater than an error code counting threshold value of the current error code counting period; if the accumulated value of the counting difference value is greater than the error code counting threshold value of the current error code counting period, generating an alarm event of the data transmission link and disconnecting the data transmission link; and if the accumulated value of the counting difference value is less than or equal to the error code counting threshold value of the current error code counting period, determining a preset value of the current error code counting period according to the error code counting threshold value, wherein the preset value is less than the error code counting threshold value; when the accumulated value of the counting difference value is greater than the preset value of the current error code counting period, taking the preset value of the current error code counting period as the error code counting basis of the next error code counting period; and when the accumulated value of the counting difference value is less than or equal to the preset value of the current error code counting period, taking the accumulated value of the counting difference value as the error code counting basis of the next error code counting period.

[0063] The preset value can be determined according to the error code counting threshold value, for example, can be half, one fourth, etc. of the error code counting threshold value, and the preset value is less than the error code counting threshold value.

[0064] It can be understood that the embodiment of the present application can determine whether the accumulated value of the counting difference value is greater than the error code counting threshold value of the current error code counting period, if the accumulated value of the counting difference value is greater than the error code counting threshold value of the current error code counting period, generate an alarm event of the data transmission link and disconnect the data transmission link, otherwise determine a preset value of the current error code counting period according to the error code counting threshold value, that is, the preset value can be determined according to the error code counting threshold value, for example, can be half, one fourth, etc. of the error code counting threshold value, and the preset value is less than the error code counting threshold value, and when the accumulated value of the counting difference value is greater than the preset value of the current error code counting period, take the preset value of the current error code counting period as the error code counting basis of the next error code counting period, and when the accumulated value of the counting difference value is less than or equal to the preset value of the current error code counting period, take the accumulated value of the counting difference value as the error code counting basis of the next error code counting period.

[0065] For example, in a SAS link environment, the error count threshold of a short error count period is 10 times, if the accumulated value of the count difference is 15 times, which is greater than 10 times, an alarm event of the SAS link is generated, and the data transmission link is disconnected; if the accumulated value of the current count difference is 6 times, which is less than 10 times, and the preset value is half of the error count threshold, for example, the preset value is 5 times, the accumulated value of the current count difference is 6 times, which is greater than 5 times, 5 times of the next error count period is set as the error count basis; if the accumulated value of the current count difference is 3 times, 3 times is set as the error count basis of the next error count period.

[0066] This way of reducing the next count processing not only considers the error history in the previous error count period, but also gives a certain buffer space, which can more flexibly adjust the monitoring strategy without affecting normal operation, which helps to avoid triggering the alarm too early because of long-term accumulation of small errors, and also ensures sufficient response ability to sudden increase of errors.

[0067] In the embodiments of the present application, the error interference threshold is set according to the error count threshold; and if the count difference is greater than the interference threshold, the interference threshold is used as the count difference.

[0068] The error interference threshold is determined according to the set error count threshold, and the interference threshold is usually set to a part of the error count threshold of the short error count period, for example, half of the error count threshold of the short error count period, in order to distinguish between occasional errors in normal operation and significant error growth possibly caused by external factors.

[0069] It can be understood that when the count difference is greater than the interference threshold, it indicates that the error increase this time may be caused by external interference or other reasons, such as a scenario of human external interference leading to a sharp increase in error count within 10 seconds, so the count error is not directly used for accumulation, but the interference threshold is used as the count difference for subsequent accumulation. By setting the error interference threshold and adjusting when the count difference exceeds the interference threshold, accidental error events can be filtered out without affecting normal operation, ensuring timely and accurate response to real error problems, and improving the accuracy of subsequent error detection results.

[0070] For example, in a short error count period, the error count threshold is 10 times, so the interference threshold can be set to 5 times, if the calculation difference is 7, 7 is directly used as the count difference for accumulation, if the calculation difference is 12, the interference threshold 5 is used as the count difference for accumulation, and the actual 12 is not used.

[0071] In some embodiments, setting the error code interference threshold according to the error code count threshold comprises: identifying an error code count period in which error code interference exists, obtaining a corresponding relationship table of the error code count period in which error code interference exists, the corresponding relationship table being a corresponding relationship between the error code count threshold and the error code interference threshold, and determining the error code interference threshold of the error code count period based on the corresponding relationship table.

[0072] It can be understood that the embodiments of the present application can determine the error code count period in which error code interference exists in advance, such as the error code count period of a short period running scene, which is prone to the scene of a sharp increase in error code count caused by external interference in a short period. Therefore, the embodiments of the present application calibrate the corresponding relationship table in advance. Since the error code count threshold can be specifically set, the error code interference threshold can be accurately determined through the corresponding relationship table, so as to improve the anti-interference capability.

[0073] The error code detection method of the data transmission link of the embodiments of the present application will be described below through a specific embodiment. Taking the SAS link as an example, the overall flow of the error code detection method of the SAS link is as shown in Figure 2 , which comprises:

[0074] 1. A plurality of error code periods are set for the uplink and downlink in the SAS link, for example, 2, 3, etc. Two error code count periods are taken as an example in the present embodiment, i.e. a long error code count period and a short error code count period, and corresponding error code count thresholds. For example, the long error code count period of the uplink is 12 hours, and the error code threshold is 30. The short error code count period is 1 minute, and the error code threshold is 10. The long error code count period of the downlink is 6 hours, and the error code threshold is 30. The short error code count period is 2 minutes, and the error code threshold is 20.

[0075] 2. A timer is started, and the program is set to obtain error code count from the SAS expander every preset time interval, for example, every 10 seconds.

[0076] 3. The SAS link error code calculation algorithm, i.e. the error code detection method of the embodiments of the present application, is set. The long error code count period (long tick) and the short error code count period (short tick) can both use this error code calculation algorithm, which is as follows:

[0077] The initial error code count is based on the first reading of the SAS expander error code count by the program running. Every 10 seconds, the current error code count (newcount) is read from the SAS expander. If the current error code count is greater than the last error code count (lastcount), and the count difference (diff) between newcount and lastcount is greater than half of the short period error code count threshold, it is considered that the error code count has increased by half of the short period error code count threshold (in order to exclude the scenario of rapid increase of error code count within 10 seconds caused by human external interference). The diff value is accumulated within the error code count period. When the accumulated diff value is greater than the error code count threshold of the count period, an alarm event of excessive error code of the SAS link is reported, and the corresponding SAS link is disconnected, i.e., the port corresponding to the SAS link is closed, and the error code of the port is no longer monitored. After the port is closed, data transmission is no longer possible, and the error code will no longer increase. If the accumulated diff value within the count period is not greater than the error code count threshold of the count period, the accumulated diff value is halved as the error code count basis to start a new count period of error code accumulation and fault judgment.

[0078] 4. Deploy the program to the storage device, and run the SAS link error code detection algorithm.

[0079] According to the error code detection method of the data transmission link provided in the embodiments of the present application, corresponding error code count periods can be set for different running scenarios, and multiple error code count thresholds are set corresponding to the multiple error code count periods, so that error code detection in different running scenarios is realized through the multiple error code count thresholds. For example, through the error code count threshold in the short period running scenario, a situation of rapid increase of error code within a short period can be discovered and responded in time. For another example, through the error code count threshold in the long period running scenario, unnecessary disconnection of the data transmission link can be avoided, so that corresponding error code count thresholds can be used for different running scenarios to avoid the inapplicability problem caused by sharing of the error code count threshold. While ensuring the accuracy of error code detection, the applicability of error code detection of the data transmission link can be effectively improved, and different error code detection requirements in different running scenarios can be effectively taken into account, thereby improving the user experience.

[0080] Secondly, the error code detection device of the data transmission link according to the embodiments of the present application is described with reference to the accompanying drawings.
