[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0042] It should be noted that in the description of the present application, the terms "include", "comprise" or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. The terms "first", "second", etc. in the present application are used to distinguish similar objects and not to describe a specific order or sequence.

In the computing device 10, a host controller 101 can be connected to a plurality of hard disks through an expander 102. Exemplarily, Figure 1 shows three hard disks, namely hard disk 103, hard disk 104, and hard disk 105.

[0044] To ensure the storage reliability of the computing device, it is necessary to perform real-time monitoring and fault location on the link.

[0045] In the related art, it is necessary to disconnect a link (a link between a hard disk and an expander, or a link between an expander and a host controller), and connect an analyzer 30 to the link (such as a link between a hard disk and an expander) to perform fault location based on the monitored link signal.

[0046] However, in the related art, the method of breaking the original link to access the analyzer, on the one hand, will change the original topology and signal transmission environment of the link, and on the other hand, can only detect the link signal of one link, resulting in the problem of low accuracy of fault location in the method of the related art.

[0047] Therefore, in view of the above technical problems in the related art, it is found in the research process that if a signal acquisition module with the ability to detect link signals (including multiple acquisition components (each acquisition component can acquire the link signal of the link)), a signal processing module with the ability to process link signals, and an expander are combined into an expansion module, and then the acquisition components are set between the host controller and the expander, or between the hard disk and the expander, the expansion module can acquire the link signals of multiple links and perform analysis without destroying the original topology and signal transmission environment of the link. Therefore, the present application proposes an expansion module, a fault location method, a terminal device, a medium and a product. Specifically, the expansion module includes an expander, a signal acquisition module and a signal processing module; the signal acquisition module includes multiple acquisition components; the expansion module belongs to a computing device; the signal processing module is respectively connected to the expander and the signal acquisition module; for any acquisition component in the signal acquisition module, the host controller in the computing device is connected to the expander through the acquisition component; or, the hard disk in the computing device is connected to the expander through the acquisition component.

[0117] Figure 5 Schematic flow of a fault location method provided by an embodiment of the present application Figure 1 , see Figure 5, the method specifically includes the following steps:

[0118] S501: Obtain a collection start instruction through the expander in the expansion module, and send the collection start instruction to the signal collection module in the expansion module.

[0119] In this embodiment, the expansion module includes an expander, a signal collection module, and a signal processing module; the signal collection module includes a plurality of collection components; the expansion module belongs to a computing device. The signal processing module is respectively connected to the expander and the signal collection module. For any collection component in the signal collection module, the host controller in the computing device is connected to the expander through the collection component; or, the hard disk in the computing device is connected to the expander through the collection component.

[0120] In one implementation, the expander includes a plurality of ports. For any collection component in the signal collection module, the host controller in the computing device is connected to a port of the expander through the collection component; or, the hard disk in the computing device is connected to a port of the expander through the collection component.

[0121] The expansion module can obtain a collection start instruction through the expander and send the collection start instruction to the signal collection module.

[0122] Next, the process of the expansion module obtaining a collection start instruction through the expander will be described.

[0123] In one implementation:

[0124] Each link includes a plurality of protocol layers. Among them, the plurality of protocol layers include a physical layer, a link layer, a port layer, a transport layer, and an application layer.

[0125] It should be noted that the link is the link where the host controller is connected to a port of the expander through a collection component. Or, the link is the link where the hard disk is connected to a port of the expander through a collection component.

[0126] The expansion module can determine whether there is a protocol layer in a fault state among the multiple protocol layers of the multiple links through the expander.

[0127] Next, the process of the expander determining whether there is a protocol layer in a fault state among the multiple protocol layers of the multiple links will be described.

[0128] In one implementation:

[0129] For any protocol layer of any link, the expansion module can obtain the value of the status register corresponding to the protocol layer through the expander. Among them,

[0130] The value of the status register is the first value or the second value. The first value indicates that the status of the protocol layer is a fault state, and the second value indicates that the status of the protocol layer is a normal state.

[0131] The expansion module can determine, through the expander, that among the multiple protocol layers of multiple links, if the value of the status register corresponding to at least one protocol layer is the first value, there is a protocol layer with a fault state among the multiple protocol layers of the multiple links.

[0132] The expansion module can determine, through the expander, that among the multiple protocol layers of multiple links, if the value of the status register corresponding to each protocol layer is the second value, there is no protocol layer with a fault state among the multiple protocol layers of the multiple links.

[0133] The expansion module can generate a collection start instruction in the case of a protocol layer with a fault state among the multiple protocol layers of multiple links through the expander.

[0134] In one implementation:

[0135] The expansion module can obtain the collection start instruction sent by the processor through the host controller through the expander.

[0136] Next, the process of the processor generating the collection start instruction will be described.

[0137] In one implementation, the collection start instruction is generated by the processor when it detects a protocol layer with a fault state among the multiple protocol layers of multiple links. In one implementation, the host controller can generate an alarm indication message when it identifies a protocol layer with a fault state among the multiple protocol layers of multiple links. When the processor obtains the alarm indication message sent by the host controller, it determines that there is a protocol layer with a fault state among the multiple protocol layers of multiple links. It should be noted that each link includes multiple protocol layers; the link is the first link or the second link.

[0138] In one implementation, the collection start instruction is generated by the processor when it detects an input / output (Input / Output, abbreviated as IO) error. For example, the collection start instruction can be generated by the processor when it detects an input / output error in hard disk 0.

[0139] In one implementation:

[0140] When the extender is connected to the terminal device, the expansion module can obtain the acquisition start instruction sent by the terminal device through the extender.

[0141] It should be noted that in one implementation, the terminal device can obtain the acquisition start request input by the user. Understandably, the terminal device can obtain the acquisition start request input by the user through the human-computer interaction interface of the terminal device. The terminal device can generate an acquisition start instruction according to the acquisition start request. In one implementation, the acquisition start request may include an analysis method. In one implementation, the analysis method may include the identifier of the target port. In addition, in one implementation, the analysis method may also include the identifier of the target protocol layer. In addition, in one implementation, the analysis method may also include the identifier of the signal feature.

[0142] S502: Through the signal acquisition module, according to the acquisition start instruction, determine at least one target acquisition component from multiple acquisition components, and based on at least one target acquisition component, acquire the link signals of at least one link.

[0143] In this embodiment, the expansion module can determine at least one target acquisition component from multiple acquisition components through the signal acquisition module according to the acquisition start instruction.

[0144] Next, the process of the expansion module determining at least one target acquisition component from multiple acquisition components through the signal acquisition module according to the acquisition start instruction will be described in detail.

[0145] In one implementation:

[0146] The acquisition start instruction does not include the identifier of at least one target port. In addition, in one implementation, the acquisition start instruction may include the identifier of the target protocol layer and / or the identifier of the signal feature.

[0147] When the expansion module determines through the signal acquisition module that the acquisition start instruction does not include the identifier of at least one target port, the expansion module can determine all ports as target ports.

[0148] The expansion module can determine the acquisition components connected to the target ports as target acquisition components through the signal acquisition module.

[0149] In one implementation:

[0150] The acquisition start instruction includes the identifier of at least one target port.

[0151] The expansion module can obtain the identifier of at least one target port in the acquisition start instruction through the signal acquisition module.

[0152] The expansion module can, through the signal acquisition module, determine at least one target port from multiple ports according to the identifier of at least one target port.

[0153] The expansion module can, through the signal acquisition module, determine the acquisition component connected to the target port as the target acquisition component.

[0154] In addition, after the expansion module determines at least one target acquisition component through the signal acquisition module, based on the at least one target acquisition component, the expansion module acquires the link signals of at least one link.

[0155] It should be noted that when the host controller in the computing device is connected to a port of the expander through the target acquisition component, the link is the link where the host controller is connected to the port of the expander through the target acquisition component. When the hard disk in the computing device is connected to a port of the expander through the target acquisition component, the link is the link where the hard disk is connected to the port of the expander through the target acquisition component.

[0156] In addition, in one implementation, during the process of the expansion module acquiring the link signals of at least one link through the signal acquisition module, the expansion module can obtain an acquisition stop instruction through the expander. The expansion module sends the acquisition stop instruction to the signal acquisition module through the expander. The expansion module, through the signal acquisition module, stops acquiring the link signals of at least one link based on the at least one target acquisition component according to the acquisition stop instruction.

[0157] S503: Obtain the link signals of at least one link sent by the signal acquisition module through the signal processing module in the expansion module.

[0158] In this embodiment, the expansion module can obtain the link signals of at least one link sent by the signal acquisition module through the signal processing module in the expansion module.

[0162] In one implementation:

[0163] For the link signal of any link, the expansion module can perform filtering processing on the link signal through the signal processing module to obtain the filtered link signal.

It should be noted that, in one implementation, the physical layer signal features may include at least one or more of the following: physical layer features, including signal amplitude, jitter (random jitter or deterministic jitter), eye opening, signal-to-noise ratio, rise time, and fall time.

[0165] The expansion module can perform decoding processing on the filtered link signal through the signal processing module to obtain the decoded link signal.

[0166] The expansion module can extract the features of the decoded link signal through the signal processing module to obtain the link layer signal features, port layer signal features, transport layer signal features, and application layer signal features in the signal features of the link.

[0167] It should be noted that, in one implementation, the link layer signal features may include at least one or more of the following: bit error rate, frame error rate, retransmission rate, link training status, and clock recovery quality information.

[0168] In one implementation, the port layer signal features may include at least one or more of the following: port type, port connection status, and physical layer utilization.

[0169] In one implementation, the transport layer signal features may include at least one or more of the following: instruction type distribution, response timeout rate, command completion time distribution, and queue depth.

[0170] In one implementation, the application layer signal features may include at least one or more of the following: the number of input / output operations per second (Input / Output Operations Per Second, abbreviated as IOPS), throughput, average response time, and input / output (Input / Output, abbreviated as IO) size distribution.

[0171] It should be noted that the signal features of at least one link are used for the terminal device to determine the cause of the fault.

[0172] Advantages of this embodiment: In this embodiment, the expansion module can obtain a collection start instruction through the expander in the expansion module and send the collection start instruction to the signal collection module in the expansion module. The expansion module can, through the signal collection module, determine at least one target collection component from multiple collection components according to the collection start instruction, and collect link signals of at least one link based on the at least one target collection component. The expansion module can obtain the link signals of at least one link sent by the signal collection module through the signal processing module in the expansion module. The expansion module can analyze the link signals of at least one link through the signal processing module to obtain signal characteristics of at least one link; the signal characteristics of at least one link are used for the terminal device to determine the cause of the fault. Through the above method of collecting and analyzing link signals based on the expansion module, the accuracy of detecting link signals is improved, thereby improving the accuracy of analyzing link signals, and further improving the accuracy of fault location (determining the cause of the fault).
