[0002] With the generation and application of large-scale data, the demand for read and write services of storage array systems is increasing day by day. The applications of large-scale data centers are also gradually increasing to cope with the processing and application of big data. Usually, there are various types of computing devices, switching networks and storage devices in large-scale data centers. And devices communicate through the switching network. Different devices have some characteristics. The initiating device needs to identify different target devices to determine the characteristics of the target device in order to achieve targeted configuration management.

[0003] In the traditional device identification method, by setting a device identifier for the target device and then querying the device identifier through a standard protocol command to determine the target device, there may be problems of incorrect device identification, and sometimes there may be a problem that only one-way device identification is completed after the device is connected, resulting in the inability of the device to communicate bidirectionally.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0043] In the prior art, in the traditional device identification method, by setting a device identifier for the target device and then querying the device identifier through a standard protocol command to determine the target device, there may be problems of incorrect device identification, and sometimes after the device is connected, only one-way device identification is completed, resulting in the problem that the device cannot communicate bidirectionally. In this application, based on matching the port connection information, the characteristics of the device can be further identified to use the connection information of the initiating device to perform secondary confirmation on the target device, and the accuracy of device connection is improved by using the two-way connection method of the upper-layer service communication module.

[0044] An embodiment of the present invention discloses a method for connecting devices of a non-volatile memory, which is applied to an initiating device pre-connected to a target device. Refer to Figure 1 as described below, the method includes:

[0045] Step S11: Receive the first port connection information saved locally by the target device between the target device and the current initiating device sent by the target device.

[0046] It should be noted that in this embodiment, both the target device and the initiating device are non-volatile memories (i.e., NVM, Non-volatile memory).

[0047] In this embodiment, before receiving the first port connection information between the target device and the current initiating device locally saved by the target device, it may further include: receiving, through a preset first information receiving interface, characteristic attribute information composed of a random number and a serial number field; and saving the characteristic attribute information to a specific location preset locally.

[0048] It can be understood that in this embodiment, for each non-volatile memory, that is, for each initiating device and target device, characteristic attribute information is preset in advance, and the characteristic attribute information is composed of a random number and a serial number field. The random number is used to distinguish the characteristic attributes of the memory, and the serial number is used to distinguish a specified memory individual. It should be noted that when setting the random number, it is necessary to ensure that the random numbers of storage devices with the same characteristics are the same.

[0049] In this embodiment, the characteristic attribute information is saved to a specific location preset locally in the memory. This specific location can be set and changed according to different scenarios, but this specific location must be located in the important data storage space.

[0050] Step S12: Determine whether the first port connection information successfully matches the second port connection information locally.

[0051] In this embodiment, determining whether the first port connection information successfully matches the second port connection information locally may include: searching for the second port connection information locally; and determining whether the target device connection interface in the first port connection information is consistent with the initiating device connection interface in the second port connection information.

[0052] In this embodiment, the initiating device and the target device have been pre-connected. Both parties to the connection will send their local port connection information to each other. After each device receives the port connection information sent by the other party, it will compare it with the local port connection information and search for the connection information with the same remote port from the local port connection information.

[0053] Step S13: If the first port connection information and the second port connection information are successfully matched, the device identification information, node identification information, and characteristic attribute information of the target device obtained through a preset command are used as the first initiator connection information and sent to the upper-layer service communication module, so that the upper-layer service communication module uses the first initiator connection information and combines the second initiator connection information sent by the target device to determine the connection relationship between the initiator device and the target device.

[0054] In this embodiment, if the two-port connection information is the same, that is, the port pairs in the two connection information that are both the initiator and the target at this time are the same, it can be determined that the two parties are the same connection.

[0055] In this embodiment, the step of using the device identification information, node identification information, and characteristic attribute information of the target device obtained through a preset command as the first initiator connection information and sending it to the upper-layer service communication module may include: obtaining the device identification information of the target device through a preset standard protocol command; receiving a first custom command through a preset second information receiving interface, and obtaining the node identification information of the target device through the first custom command; receiving a second custom command through the preset second information receiving interface, and obtaining the characteristic attribute information stored at a specific location preset locally in the target device through the second custom command; using the device identification information, node identification information, and characteristic attribute information of the target device as the first initiator connection information and sending it to the upper-layer service communication module.

[0056] That is to say, in this embodiment, the device identification information, node identification information, and characteristic attribute information of the target device are determined successively. Specifically, the device identification information of the target device can be obtained through a standard protocol command, and the node identification information and characteristic attribute information of the target device are obtained through user-defined commands. In a specific implementation manner, the preset standard protocol command is a standard NVMe protocol command, and both the first custom command and the second custom command are NVMe protocol custom commands.

[0057] It should be noted that in this embodiment, the device identification is used to distinguish the device type, the node identification is used to determine which node device the device is, and the characteristic attribute information is used to determine what characteristic attributes the device has.

[0058] In this embodiment, after obtaining the characteristic attribute information stored at a specific location preset locally in the target device through the second custom command, it may further include: saving the device identification information, node identification information, and characteristic attribute information of the target device locally.

[0059] In this embodiment, after the two devices are connected, both device grids acting as the initiating device will send information requests to the other device acting as the target device to obtain the device identification information, node identification information, and characteristic attribute information of the other device acting as the target device. After obtaining this information, it will be saved locally for subsequent business applications.

[0060] In this embodiment, sending the device identification information, node identification information, and characteristic attribute information of the target device obtained through a preset command to the upper-layer service communication module as the first initiating device connection information, so that the upper-layer service communication module uses the first initiating device connection information and combines the second initiating device connection information sent by the target device to determine the connection relationship between the initiating device and the target device, may include: sending the device identification information, node identification information, and characteristic attribute information of the target device obtained through a preset command to the upper-layer service communication module as the first initiating device connection information, so that the upper-layer service communication module uses the first node identification in the first initiating device connection information and the second node identification in the second initiating device connection information sent by the target device to determine the connection relationship between the initiating device and the target device.

[0061] In this embodiment, for each device, itself is the initiating device, and the other device connected to itself is the target device. After checking the port connection information, the initiating device connection information generated by each will be sent to the upper-layer service communication module. When the upper-layer service communication module receives the initiating device connection information sent by each device, it will determine which two devices are in a connected state based on the node identification information in each initiating device connection information, thereby performing a secondary check on the connection relationship between the two devices, and then ensuring the two-way communication between the two devices.

[0062] In this embodiment, the initiating device that is pre-connected to the target device first receives the first port connection information saved locally on the target device and between the current initiating device sent by the target device, and then determines whether the first port connection information successfully matches the second port connection information locally. If the first port connection information successfully matches the second port connection information, the device identification information, node identification information, and characteristic attribute information of the target device obtained through a preset command are sent as the first initiating device connection information to the upper-layer service communication module, so that the upper-layer service communication module can use the first initiating device connection information and combine the second initiating device connection information sent by the target device to determine the connection relationship between the initiating device and the target device. In this way, the present invention can first perform connection matching based on the port connection information, and then report the detailed information such as the device identification information, node identification information, and characteristic attribute information to the upper-layer service communication module for secondary matching. The unique target device can be determined through two matches, ensuring the accuracy of the connection of the target device. In addition, the upper-layer service communication module can use the two types of initiating device connection information sent by the initiating device and the target device to perform two-way verification on the initiating device and the target device, so as to ensure the two-way connection relationship between the initiating device and the target device, and ensure that the initiating device and the target device can communicate bidirectionally.

[0063] Figure 2 It is a flowchart of a device connection method for a specific non-volatile memory provided by an embodiment of the present application. Refer to Figure 2 As shown, the method includes:

[0064] Step S21: Receive the first port connection information saved locally on the target device and between the current initiating device sent by the target device.

[0065] Among them, for a more specific processing process of step S21, reference can be made to the corresponding content disclosed in the foregoing embodiment, and details will not be elaborated here.

[0066] Step S22: Determine whether the first port connection information successfully matches the second port connection information locally.

[0067] Among them, for a more specific processing process of step S21, reference can be made to the corresponding content disclosed in the foregoing embodiment, and details will not be elaborated here.

[0068] Step S23: If the first port connection information and the second port connection information are successfully matched, the device identification information, node identification information, and characteristic attribute information of the target device obtained through a preset command are sent as the first initiator connection information to the upper-layer service communication module, so that the upper-layer service communication module can use the first initiator connection information and combine it with the second initiator connection information sent by the target device to determine the connection relationship between the initiator device and the target device.

[0069] Step S24: Obtain the service data request for the target device generated by the upper-layer service communication module based on the first initiator connection information and the second initiator connection information.

[0070] In this embodiment, after the upper-layer service communication module determines the connection relationship between the initiator device and the target device according to the first initiator connection information and the second initiator connection information, it can then know what characteristic attributes each of the two devices in the connected state has based on the characteristic attribute information in each initiator connection information. And since both of these two devices have the characteristic attribute information of the other party, flexible applications can be made based on the connection relationship between these two devices and the information stored therein during subsequent service applications. For example, in some specific implementation manners, if the upper-layer service communication module needs to request service data located in a pair of initiator devices and target devices at the same time, since the initiator device and the target device both store some service data of the other party, the upper-layer service communication module does not need to send data requests to both devices at the same time. It only needs to select one of the devices to send a data request to request the service data originally located in the two devices.

[0071] In this step, after the upper-layer service communication module determines the connection state between the initiator device and the target device, it may send a service data request to any device. This service data request may be for this device itself or for the target device connected to this device.

[0072] Step S25: Determine the service data corresponding to the service data request based on the device identification information, node identification information, and characteristic attribute information of the target device saved locally, and return the service data to the upper-layer service communication module.

[0073] In this step, when the initiator device receives the service data request for the target device sent by the upper-layer service communication module, it can determine the service data corresponding to the service data request according to the device identification information, node identification information, and characteristic attribute information of the target device saved locally, and finally return the service data to the upper-layer service communication module for the upper-layer service communication module to perform service applications.

[0074] In this way, the present invention can first perform connection matching based on port connection information, and then report detailed information such as device identification information, node identification information, and characteristic attribute information to the upper-layer service communication module for secondary matching. The two matches can determine the unique target device, ensuring the accuracy of the connection of the target device. In addition, the upper-layer service communication module can use two types of initiating device connection information sent by the initiating device and the target device to perform two-way verification on the initiating device and the target device, so as to ensure the two-way connection relationship between the initiating device and the target device. While ensuring that the initiating device and the target device can communicate bidirectionally, subsequent flexible service applications can also be carried out based on the connection relationship and stored content of the two devices.
