Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a PCIe Switch detection method according to an embodiment of the present application.
The PCIe Switch detection method provided by the embodiment of the present application may include the following steps:
step S101: judging whether the real-time firmware information and the real-time driving information of the target PCIe Switch meet a first preset requirement or not; if the real-time firmware information and the real-time driving information do not meet the first preset requirement, executing step S102; if the real-time firmware information and the real-time driving information meet the first preset requirement, step S103 is executed.
Step S102: the determination target PCIe Switch is unstable.
In practical application, since the real-time firmware information and the real-time driving information directly influence the working condition of the target PCIe Switch, whether the real-time firmware information and the real-time driving information of the target PCIe Switch meet the first preset requirement can be judged; if the real-time firmware information and the real-time driving information do not meet the first preset requirement, the method can be ended, and the unstable target PCIe Switch and the like can also be directly judged; if the real-time firmware information and the real-time driving information meet the first preset requirement, a subsequent judging step needs to be executed to determine the stability of the target PCIe Switch.
Step S103: judging whether the negotiated bandwidth and the real-time transmission rate of the target PCIe Switch meet a second preset requirement or not; if the negotiated bandwidth and the real-time transmission rate do not meet the second preset requirement, executing step S104; if the negotiated bandwidth and the real-time transmission rate meet the second preset requirement, step S105 is executed.
Step S104: the determination target PCIe Switch is unstable.
In practical application, since the negotiated bandwidth and the real-time transmission rate determine the transmission condition of the target PCIe Switch during operation, if the real-time firmware information and the real-time driving information meet the first preset requirement, it is necessary to determine whether the negotiated bandwidth and the real-time transmission rate of the target PCIe Switch meet the second preset requirement; if the negotiated bandwidth and the real-time transmission rate do not meet the second preset requirement, the method can be ended, and the unstable target PCIe Switch and the like can also be directly judged; if the negotiated bandwidth and the real-time transmission rate meet the second preset requirement, a subsequent determination step needs to be performed to determine the stability of the target PCIe Switch.
Step S105: judging whether the target PCIe Switch is in an activated state or not; if the link of the target PCIe Switch is not in an active state, executing step S106; if the link of the target PCIe Switch is in an active state, step S107 is executed.
Step S106: the determination target PCIe Switch is unstable.
In practical applications, if the target PCIe Switch is in an inactive state, it may indicate that the target PCIe Switch has a fault, so after the negotiated bandwidth and the real-time transmission rate meet the second preset requirements, it needs to be determined whether the target PCIe Switch is in an active state; if the link of the target PCIe Switch is not in an active state, the method can be ended, or the unstable target PCIe Switch can be directly judged; if the link of the target PCIe Switch is in an active state, then a subsequent determination step needs to be performed to determine the stability of the target PCIe Switch.
Step S107: acquiring performance information of the target PCIe Switch, acquiring error code information of the target PCIe Switch, and performing stability analysis on the target PCIe Switch based on the performance information and the error code information to obtain a target analysis result so as to perform stability analysis on a link of the target PCIe Switch based on the target analysis result.
In practical applications, since both the performance information and the error code information of the target PCIe Switch affect the working stability of the target PCIe Switch, the performance information of the target PCIe Switch needs to be acquired, the error code information of the target PCIe Switch is acquired, and stability analysis is performed on the target PCIe Switch based on the performance information and the error code information, so as to obtain a target analysis result.
It should be noted that, since the target PCIe Switch belongs to a PCIe link and affects the operation condition of the PCIe link, after the target analysis result is obtained, the stability analysis can be performed on the link of the target PCIe Switch based on the target analysis result.
According to the PCIe Switch detection method, whether the real-time firmware information and the real-time driving information of the target PCIe Switch meet the first preset requirement is judged; if the real-time firmware information and the real-time driving information meet the first preset requirement, judging whether the negotiation bandwidth and the real-time transmission rate of the target PCIe Switch meet the second preset requirement; if the negotiated bandwidth and the real-time transmission rate meet the second preset requirement, judging whether the target PCIe Switch is in an activated state or not; if the link of the target PCIe Switch is in an active state, acquiring performance information of the target PCIe Switch, acquiring error code information of the target PCIe Switch, and performing stability analysis on the target PCIe Switch based on the performance information and the error code information to obtain a target analysis result so as to perform stability analysis on the link of the target PCIe Switch based on the target analysis result. According to the method and the device for analyzing the stability of the target PCIe Switch, the stability analysis of the target PCIe Switch is achieved, and the accuracy of the link stability analysis can be improved when the stability analysis of the link of the target PCIe Switch is carried out based on the target analysis result.
In the PCIe Switch detection method provided by the embodiment of the present application, in a process of obtaining the error code information of the target PCIe Switch, in order to facilitate obtaining the error code information, the error code information may be directly read in a register of the target PCIe Switch.
In practical application, in the process of performing stability analysis on the target PCIe Switch based on the performance information and the error code information to obtain a target analysis result, the stability analysis can be performed on the target PCIe Switch based on the performance information to obtain a first analysis result; performing stability analysis on the target PCIe Switch based on the error code information to obtain a second analysis result; and determining a target analysis result based on the first analysis result, the weight of the first analysis result, the second analysis result and the weight of the second analysis result. The first analysis result and the second analysis result can be comprehensively considered to obtain an accurate target analysis result.
Of course, in practical applications, it may be directly set that the target PCIe Switch is stable only when the first analysis result and the second analysis result indicate that the target PCIe Switch is stable, and in addition, the target PCIe Switch is unstable. In addition, in the process of determining the target analysis result based on the first analysis result, the weight of the second analysis result, and the weight of the second analysis result, the corresponding stability score may be calculated based on the weight of the first analysis result, the weight of the second analysis result, and then the target analysis result may be determined according to the stability score.
It should be noted that, in the present application, the performance information of the target PCIe Switch may include IOPS, latency, CPU utilization, and the like, and the specific type thereof may be determined according to actual needs.
In practical application, in the process of performing stability analysis on the target PCIe Switch based on the performance information to obtain a first analysis result, whether the performance information meets the preset performance requirement can be judged; if the performance information meets the preset performance requirement, a first analysis result representing the stable performance of the target PCIe Switch is obtained; if the performance information does not meet the preset performance requirement, a first analysis result representing unstable performance of the target PCIe Switch is obtained.
In practical application, in the process of performing stability analysis on the target PCIe Switch based on the error code information to obtain a second analysis result, whether the increase rate of the error code information is larger than a preset value can be judged; if the growth rate is greater than the preset value, generating a second analysis result representing that the error code of the target PCIe Switch is unstable; and if the growth rate is smaller than or equal to a preset value, generating a second analysis result representing the error code stability of the target PCIe Switch. Of course, it may also be directly determined whether the number of errors in the error information is greater than a preset number, if the number of errors is greater than the preset number, a second analysis result indicating that the error of the target PCIe Switch is unstable is generated, and if the number of errors is less than or equal to the preset number, a second analysis result indicating that the error of the target PCIe Switch is stable is generated.
In the PCIe Switch detection method provided by the embodiment of the present application, in a process of determining whether the real-time firmware information and the real-time driving information of the target PCIe Switch meet the first preset requirement, whether the real-time firmware information is consistent with the target firmware information may be determined, if the real-time firmware information is consistent with the target firmware information, the real-time firmware information is determined to meet the first preset requirement, and if the real-time firmware information is inconsistent with the target firmware information, the real-time firmware information is determined to not meet the first preset requirement; judging whether the real-time driving information is consistent with the target driving information or not, if so, judging that the real-time driving information meets the first preset requirement, and if not, judging that the real-time driving information does not meet the first preset requirement.
