The expansion of SAS ports is achieved by the expander, and the expansion can be achieved to 36/48/64, so that a plurality of Physical (PHY) ports are corresponding, each PHY port has independent register configuration space (including a physical layer register and a link layer register) for physically transmitting data, and Input/Output (IO) service is processed, so that each PHY port may correspond to hundreds of registers.

Since the expander runs tens of independent PHY links, each with hundreds of independent registers, this large amount of information cannot be fully logged. Corresponding register information is queried or processed through related instructions, and one instruction is input at a time, so that corresponding information is queried or corresponding PHY functions are realized. However, for querying or processing multiple register information, tens or even hundreds of instructions need to be entered, resulting in the inefficiency of the data processing process of existing expanders. Therefore, there is a need for a data processing method, system, electronic device and storage medium based on expanders to solve the above problems.

The storage system processes mass data transmitted between the server and the hard disk with high reliability and high speed as requirements, and for a system interface, a central processing unit (Central Processing Unit, CPU for short) is externally provided with a high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE for short) interface when processing service data, and the hard disk device is generally provided with an SAS interface, so that the PCIE interface is usually converted into the SAS interface and is butted to each hard disk by an expander to ensure IO communication between the storage system and each hard disk; in addition, the expander can also realize a chassis management function, and can detect the states of various hardware in the chassis in real time to determine whether fault abnormality occurs.

In the development process, a corresponding interaction interface is provided through the expander, so that the following operation is performed on each PHY port: initialization configuration, opening or closing, inquiry of various status registers, debugging configuration parameters, control register configuration, fault injection test and the like. In the maintenance process, when the hard disk fails, the state of the register is checked through the expander, so that the failure cause is judged.

Existing expanders typically run tens of independent PHY links with hundreds of independent registers per PHY link. When hard disk failure occurs and the link state needs to be checked, each PHY link has more than ten registers such as Change count, invalid DWORDs, diversity Errors, dowrd Sync lost, etc., more than 360 registers for an expander with 36 PHY links, and more than 680 registers for an expander with 68 PHY links. According to the existing log record and instruction query mode, query instructions need to be executed one by one, on one hand, a user needs to know specific instructions, and on the other hand, the user needs to interact many times. For such a large amount of information, the information cannot be recorded in the log, and when development, debugging and fault positioning are performed in the prior art, a large amount of instructions need to be manually input according to data processing requirements (such as inquiring certain register data or modifying parameters of the register data), so that the efficiency is low, and the development, the debugging and the fault positioning are not facilitated.

Specifically, on the basis of the foregoing embodiment, the acquiring the first input information includes:

In the invention, a visualization tool is developed through a user side, so that a method for inquiring and controlling expander information is provided for a user. Specifically, in the tool, the communication ports (such as serial ports, parallel ports and network ports) are utilized to interact with the expander, so that information required by a user, namely option information checked by the user on an operation interface of the visualization tool, is converted into batch interaction instructions, the receiving and sending of the instructions are automatically completed, and the execution result on one side of the expander is visually displayed. In the invention, the extender receives the interactive instruction, executes the interactive instruction in an instruction mode and returns a corresponding result.

In the invention, the visualization tool forms various interactive interfaces and instructions according to the design, development and maintenance stages and aiming at related information (such as expander model information, register address information, register function types and the like) acquired by different types of expanders, so that the user side can utilize a communication port to interact with the expander to automatically convert the operation of the user on the visualization tool into the query instruction or the control instruction of each PHY_ID, thereby saving the batch instruction execution of the user, greatly displaying and greatly improving the data processing efficiency aiming at the development, debugging and product maintenance stages.

In the invention, a user side forms a table display interface of a two-dimensional array table through a visualization tool. In an embodiment, if the interactive function is a query function, that is, the PHY port number to be queried at this time in the table display interface is checked on the visualization tool at the user side, after the expander returns the query information, a corresponding query task is obtained and displayed on the table display interface, where the transverse direction in the table display interface is various PHY information, and the ID of each PHY port is longitudinally corresponding. In another embodiment, if the interactive function is a control function, PHY port numbers to be queried at this time in the table display interface are checked on the visualization tool at the user side, and meanwhile, the visualization tool also provides control function options corresponding to each PHY port number on the table display interface according to register control functions of different types of expanders, so that after any option is checked, an instruction identifiable by the expanders can be automatically cleared, and corresponding control functions are further realized through register data corresponding to the PHY ports. Specifically, the interactive function options include PHY port initialization status information interactive options, register address information interactive options, input/output information interactive options, physical control function interactive information and chassis management information interactive options, which can be set correspondingly on the form display interface according to the query and control requirements.

In the invention, the visual tool provides a convenient operation mode for a user, only information on the interface is needed to be clicked, the tool is used for escaping into batch instructions interacted with the expander, a plurality of instructions can be sent simultaneously, the number of the instructions is equal to the number of PHYs, the result can be displayed according to the PHY port structure, and the user experience is improved while the data processing efficiency is improved.

Step 102, responding to the first input information, obtaining corresponding target register address information according to the target physical port information, and generating data interaction instruction information according to the target register address information and the target interaction function information.

In an embodiment, a "read" button is selected on a table display interface through a visualization tool at the user side, and each "read" button corresponds to one PHY port ID, that is, register data of a PHY port to be currently queried can be selected through the user side, and then the read operation is converted into a query instruction sent to the expander; when a plurality of ports are inquired, the instructions which are referred to as each PHY port ID are sent one by one through a batch sending instruction so as to inquire the register information corresponding to each PHY port ID. In the invention, corresponding options can be set on the table display interface according to the data type information of the data to be queried, for example, the options are set as query register instruction information options, and after the options are checked, the expander feeds back the corresponding register instruction query result according to the received query instruction.

In another embodiment, a "write" button is selected on the form display interface by a visualization tool at the user side; meanwhile, a plurality of control information options (generated based on functions which can be realized by different types of expanders) are transversely displayed on the table display interface, and then each control information option on the table display interface is checked according to different control requirements. In this embodiment, each control information option corresponds to a Command Prompt (CMD) of a different class, so that a user can conveniently select a corresponding control manner, for example, initialization configuration of each PHY port, reading and writing of a physical layer register, reading and writing of a link layer register, reading and writing of chassis management information, and the like, so as to escape currently-selected option information into a control instruction sent to the expander. Table 1 is a table content of a table display interface for controlling the enabling and signal flipping of PHY ports, and reference may be made to table 1 as follows:

TABLE 1

In table 1, if R/W is checked, it indicates that the corresponding PHY port needs to perform a corresponding read/write operation, after determining that PHY ports 1 to 4 are checked, further determining, according to checked control information options, that the corresponding control function that the expander is required to implement at this time, for example, "PHY Enable" and "RX Swap" options of PHY ports 1 to 3 are checked, the expander receives a corresponding control instruction, further sets PHY ports 1 to 3, enables the first 3 PHYs, and meanwhile performs RX (receive) signal inversion on the 3 PHYs; accordingly, the "PHY Enable" and "TX Swap" options of the PHY port 4 are checked, and the expander receives the corresponding control instruction, so as to set the PHY port 4, enable the PHY port 4, and simultaneously perform TX (output) signal flipping on the PHY port 4.

In this embodiment, according to the interactive function information, corresponding register data is first queried, the queried register data is displayed on the table display interface, and a modification function is provided on the table display interface, so that parameter modification is performed on the register data corresponding to different PHY ports. Preferably, in this embodiment, for the register control function of different PHY ports, corresponding parameter function options may be directly displayed on the table display interface, that is, corresponding parameter setting values are directly filled in the options, without the need for the user to reset the whole register instruction, for example, in oscilloscope measurement, bit ranges of different registers correspond to different functions, and on the table display interface, parameter setting values of each function option correspond to bit ranges, so that when parameter modification is performed, only parameters of corresponding bit ranges are modified, and signal quality under a large number of parameters can be obtained in a short time. Table 2 is a table content of a table display interface for output signal debugging, and can be referred to as table 2:

TABLE 2

In table 2, according to the checked read-write options, it is determined that the parameter values corresponding to PHY1 to PHY4 need to be modified (specific values may be actually filled in), and then according to the filled parameter modification values, after the expander receives the corresponding parameter modification instruction, the writing of the parameters is quickly completed. Preferably, in this embodiment, for parameter modification of the interactive function scene, the current parameter value is obtained through a read operation, and displayed through a visual interface, so that a user can refer to the displayed current parameter value, and then parameter setting values of function options corresponding to a table display interface are modified, so as to improve stability of the device.

In the invention, each option in the table display interface has constructed the mapping relation of PHY port information and register address information in the early stage, at the same time, the register addresses of different PHY port IDs correspond to different control functions, thus establishing the function option of the table display interface, when a certain function option is checked, the user terminal generates data interaction instruction information according to the PHY port information and the corresponding register address information and the function type to be realized by the function option, and then sends the data interaction instruction information to the expander, so that the expander carries out corresponding processing according to the register data of the corresponding PHY port, and returns the query result or the control result to the user terminal.

In an embodiment, when a register instruction needs to be queried, a user clicks a read instruction and checks a register instruction query option (the option can set multiple sub-items according to actual needs), further, based on the check option information, the user end parses PHY port information and register address information of the register instruction currently needing to be queried in batches, and sends the parsed query instruction to an expander, after all queries are completed, the user end displays query results in a two-dimensional table manner through a visualization tool, and specifically can be referred to as table 3:

TABLE 3 Table 3

In the form of table 3, the register instruction of each PHY port is obtained by fast polling, so that possible fault types can be conveniently and rapidly located.

Specifically, when the visualization tool is started, firstly, according to the transmitted port, a corresponding debugging terminal such as a serial port tool, a network security Shell protocol (SSH for short) and the like is used; then, the visualization tool enters an initialization stage, automatically initiates an expander model query instruction, analyzes the configuration file of the model pair according to the queried expander model, and analyzes the obtained configuration file information to contain: the PHY number of the expander, the register address, the correspondence of each PHY port ID and SLOT slot_id, the chassis management information configuration, the register instruction type, and the like. The mapping relation between each PHY port and the register address is established by analyzing the configuration file corresponding to the current expander, and further register instruction type information of different types of registers (such as a control register, a status register, an error count register and the like) is determined, so that the visualization tool generates a corresponding table display interface according to the previously established mapping relation and the like of the expanders of various types, and a user can conveniently operate corresponding interactive functions on the user side.
