[0069] Figure 3 This is a structural block diagram of a network card storage driver upgrade device provided in an embodiment of the present invention. Detailed Implementation

[0070] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0071] In existing traditional technologies, smart network interface cards (NICs) only provide one PCIe device to receive input / output requests sent by the host. Therefore, during the upgrade of the smart NIC storage driver, user storage services may be slowed down or even interrupted.

[0072] One of the core concepts of this invention is that the network card provides multiple PCIe devices to receive input / output requests sent by the host, and provides a storage driver switching function between network card PCIe devices. When the network card storage driver is upgraded, the lower version storage driver is run first. After the higher version storage driver runs normally and provides services, the lower version process automatically exits and the higher version storage driver is run. The whole process is imperceptible to the user and the storage service is uninterrupted.

[0073] Reference Figure 1 The diagram illustrates a flowchart of a network interface card (NIC) storage driver upgrade method according to an embodiment of the present invention. The NIC is configured with a first peripheral component interconnect (PCIe) device and a second PCIe device. The first PCIe device is equipped with a first storage driver. The first PCIe device and the second PCIe device are communicatively connected to the host. The method may specifically include the following steps:

[0074] Step 101: When the network card storage driver upgrade is not triggered, the input / output request sent by the host is received through the first PCIe device, and the input / output request sent by the host is processed through the first storage driver.

[0075] PCIe (Peripheral Component Interconnect) devices are devices that conform to the PCIe bus standard. PCIe devices can receive and send input / output requests.

[0076] A network card is typically configured with multiple PCIe devices. In this application, at least two of the PCIe devices are activated and used to receive input / output requests sent by the host. The two PCIe devices are the first PCIe device and the second PCIe device, respectively. In this application, there is no restriction on the order in which the PCIe devices on the network card are used.

[0077] When the network card storage driver upgrade is not triggered, the input / output requests sent by the host can be received through the first PCIe device, and the input / output requests sent by the host can be processed through the first storage driver.

[0078] In one embodiment, a third PCIe device is configured on the host, and the host receives input / output requests sent by the host through a first PCIe device, including: receiving input / output requests sent by the host through the third PCIe device; sending the input / output requests from the third PCIe device to the first PCIe device through a network interface card (NIC); and receiving the input / output requests through the first PCIe device.

[0079] The host computer is configured with multiple PCIe devices. These devices are used to receive input / output requests from the host and, via the network interface card (NIC), to send these requests to the corresponding PCIe devices on the NIC. In this invention, the third PCIe device can be any PCIe device on the host used for receiving and sending input / output requests. When the third PCIe device receives an input / output request from the host, it can send the request to the first PCIe device via the NIC, and the first PCIe device receives the request.

[0080] In one embodiment, the first storage driver stores a mapping relationship between a third PCIe device and backend storage. The mapping relationship indicates the correspondence between an input / output request sent by the third PCIe device and a backend device for receiving the input / output request. Processing the input / output request sent by the host through the first storage driver includes: obtaining the input / output request and third PCIe device information from the first PCIe device through the first storage driver. The third PCIe device information includes a third PCIe device number, which is generated by the network card when sending the input / output request from the third PCIe device to the first PCIe device; and finding the corresponding backend device for receiving the input / output request based on the third PCIe device information and the mapping relationship through the first storage driver, and sending the input / output request to the corresponding backend device.

[0081] After an input / output request sent by the host is forwarded to the PCIe device on the network interface card (NIC), a backend device is needed to receive and complete this input / output request. Therefore, a mapping relationship needs to be established between the third-party PCIe device and the backend storage, so that the backend device used to receive the input / output request sent by the third-party PCIe device can be found through the mapping relationship.

[0082] This mapping relationship is stored in the network card storage driver. Therefore, when the first storage driver obtains the input / output request and the third PCIe device information from the first PCIe device, it can find the corresponding back-end device for receiving the input / output request based on the third PCIe device information and the mapping relationship, and send the input / output request to the corresponding back-end device.

[0083] Step 102: When the network card storage driver upgrade is triggered, start the second storage driver and mount the second storage driver to the second PCIe device.

[0084] When a network card storage driver upgrade is triggered, a second storage driver can be started and mounted to a second PCIe device.

[0085] Attaching a second storage driver to a second PCIe device may include: activating the second PCIe device and accessing the second PCIe device through the second storage driver. A network card may be configured with multiple PCIe devices, but typically only one PCIe device is activated and used to receive input / output requests from the host. When a network card storage driver upgrade is triggered, the second PCIe device can be activated, enabling it to also receive input / output requests from the host, and allowing the second storage driver to access the second PCIe device and obtain input / output requests from it.

[0086] Step 103: In response to the completion of the network card storage driver upgrade, receive input / output requests sent by the host through the second PCIe device, process the input / output requests sent by the host through the second storage driver, and exit the first storage driver.

[0087] When the network card storage driver upgrade is complete, the second PCIe device can begin receiving input / output requests from the host, and the second storage driver can access the second PCIe device, retrieve input / output requests from the second PCIe device, and process the input / output requests. Simultaneously, when the network card storage driver upgrade is complete, the first storage driver exits.

[0088] In one embodiment, the host is configured with a third PCIe device, and the second PCIe device is used to receive input / output requests sent by the host, including: receiving the input / output requests sent by the host through the third PCIe device; sending the input / output requests from the third PCIe device to the second PCIe device through the network interface card; and receiving the input / output requests through the second PCIe device.

[0089] In one embodiment, the second storage driver stores a mapping relationship between a third PCIe device and backend storage. The mapping relationship indicates the correspondence between input / output requests sent by the third PCIe device and the backend device used to receive the input / output requests. Processing the input / output requests sent by the host through the second storage driver includes: obtaining the input / output requests and third PCIe device information from the second PCIe device through the second storage driver. The third PCIe device information includes a third PCIe device number, which is generated by the network card when sending the input / output requests from the third PCIe device to the second PCIe device; and using the second storage driver, finding the corresponding backend device used to receive the input / output requests based on the third PCIe device information and the mapping relationship, and sending the input / output requests to the corresponding backend device.

[0090] In one embodiment, step 103 may include the following sub-steps:

[0091] Sub-step S11: Obtain the mapping relationship between the third PCIe device and the back-end storage. The mapping relationship is used to indicate the correspondence between the input / output requests sent by the third PCIe device and the back-end device used to receive the input / output requests.

[0092] Sub-step S12: After mounting the second storage driver to the second PCIe device, the mapping relationship is loaded into the second storage driver;

[0093] Sub-step S13: After the second storage driver is loaded, the input / output request sent by the host is received through the second PCIe device, and the input / output request sent by the host is processed through the second storage driver, and the first storage driver is exited.

[0094] After obtaining the mapping relationship between the third PCIe device and the back-end storage, the mapping relationship can be loaded into the second storage driver, which can be obtained from the first storage driver. Once the second storage driver has loaded the mapping relationship, the second PCIe device can begin receiving input / output requests sent by the host, processing these requests through the second storage driver, and exiting the first storage driver.

[0095] In one embodiment, exiting the first storage driver in response to the completion of the network interface card (NIC) storage driver upgrade may include: stopping sending input / output requests to the first PCIe device in response to the completion of the NIC storage driver upgrade; and exiting the first storage driver in response to the completion of processing the input / output requests.

[0096] When the network card storage driver upgrade is complete, it can stop sending input / output requests to the first PCIe device. Also, when the first storage driver finishes processing the remaining input / output requests, it can exit. The first storage driver can finish processing the remaining input / output requests in two ways: the first storage driver sends the unsent input / output requests to the corresponding backend device, or the first storage driver sends the unsent input / output requests to the corresponding backend device and receives an indication from the backend device that the input / output requests have been completed.

[0097] In one embodiment, in response to the completion of the network card storage driver upgrade and the completion of the input / output request sent by the first storage driver by the backend device, the second PCIe device receives the input / output request sent by the host, processes the input / output request sent by the host by the second storage driver, and exits the first storage driver.

[0098] When the network card storage driver upgrade is complete, the first storage driver can send any unprocessed input / output requests to the corresponding backend device. After the corresponding backend device receives and completes the input / output request, it can send a response message containing an indication that the input / output request has been completed. In response to this indication, the second PCIe device receives the input / output request sent by the host, processes the input / output request sent by the host through the second storage driver, and exits the first storage driver.

[0099] In one embodiment, after the network interface card (NIC) storage driver upgrade is complete, if another upgrade of the NIC storage driver is required, i.e., the second storage driver needs to be exited and a third storage driver used, the third storage driver can be started and attached to the first PCIe device. In response to the completion of the NIC storage driver upgrade, the first PCIe device receives input / output requests sent by the host, and the third storage driver processes these requests, while the second storage driver exits. Alternatively, the third storage driver can be attached to a fourth PCIe device on the NIC. In response to the completion of the NIC storage driver upgrade, the fourth PCIe device receives input / output requests sent by the host, and the third storage driver processes these requests, while the second storage driver exits.

[0100] Reference Figure 2 This diagram illustrates a network interface card (NIC) storage driver upgrade method according to an embodiment of the present invention. Before and during the NIC storage driver upgrade, the host sends input / output requests to the host PCIe device. The host PCIe device then forwards the input / output requests via the NIC to NIC PCIe device 1. The old storage driver obtains the input / output requests from NIC PCIe device 1 and sends them to the corresponding backend storage device according to the mapping relationship. After the upgrade is complete, the host PCIe device stops sending input / output requests to NIC PCIe device 1 and instead sends them to NIC PCIe device 2. The new storage driver obtains the input / output requests from NIC PCIe device 2 and sends them to the corresponding backend storage device according to the mapping relationship.

[0101] When the network interface card (NIC) storage driver upgrade is not triggered, input / output requests sent by the host are received through the first PCIe device on the NIC, and processed by the first storage driver. When the NIC storage driver upgrade is triggered, the second storage driver is started and mounted to the second PCIe device. In response to the completion of the NIC storage driver upgrade, input / output requests sent by the host are received through the second PCIe device, processed by the second storage driver, and the first storage driver is exited. This method allows the NIC to continuously process input / output requests sent by the host during the NIC storage driver upgrade, thereby avoiding storage service lag or even interruption.

[0102] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.

[0103] Reference Figure 3 This diagram illustrates a structural block diagram of a network interface card (NIC) storage driver upgrade device according to an embodiment of the present invention.
