[0032] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] The embodiment of the present application provides a firmware refresh method, and the method is described in detail below in conjunction with the execution process of the firmware refresh method. Figure 1 As shown, the firmware refresh method includes:

[0034] S101: Refresh the firmware of the first switch;

[0035] S102: Detect whether the firmware of the first switch is updated successfully;

[0040] For GPU boards with multiple switch chips, confirm the GPU board's topology information, topology ID, and firmware version, and save the switch chip configuration file in the format: Chip Number_GPU Topology_Topology ID_FW Version.

[0041] The correspondence between GPU topology, topology ID, and FW version can be found in Table 1:

[0042] Table 1

[0043]

[0044] Flash the new firmware to the first switch chip, i.e., the first switch. After the flash is complete, confirm the firmware version information and operating status of the first switch to determine whether the firmware of the first switch was successfully flashed. If the firmware version information and operating status are normal, the firmware flash is considered successful. If the firmware version information or configuration file is abnormal, the firmware flash is considered unsuccessful. If the flash fails, a restore command is issued to the first switch via the second switch chip, i.e., the second switch, and the old firmware of the second switch is used to restore the firmware of the first switch. If the firmware of the first switch is successfully flashed, the new firmware image file and corresponding configuration file are retained.

[0045] In some embodiments, sending a restore instruction to the first switch and restoring the firmware of the first switch using the firmware of the second switch includes:

[0046] If the topology of the image processor is a balanced topology, the first processor notifies the second processor of the failure to update the first switch firmware, and the second processor notifies the second switch of the failure to update the first switch firmware, so that the second switch issues a restore instruction to the first switch. The second switch transfers the firmware image file of the second switch to the first switch and restores the firmware of the first switch according to a corresponding configuration file. In the balanced topology, the first processor is connected to the first switch and the second processor, the second processor is connected to the second switch, and the first switch is connected to the second switch.

[0047] If the image processor topology is a universal topology, the first processor notifies the second switch that the firmware update of the first switch has failed, causing the second switch to issue a restore instruction to the first switch. The second switch then transfers the firmware image file of the second switch to the first switch and restores the firmware of the first switch according to the corresponding configuration file. In the universal topology, the first processor is connected to the first switch, the second switch, and the second processor, respectively, and the first switch is connected to the second switch.

[0048] If the image processor topology is a cascade topology, the first processor notifies the second switch via the first switch that the firmware update of the first switch has failed, causing the second switch to issue a restore instruction to the first switch. The second switch then transfers the firmware image file of the second switch to the first switch and restores the firmware of the first switch according to a corresponding configuration file. In the cascade topology, the first processor is connected to the first switch and the second processor, respectively, and the first switch is connected to the second switch.

[0049] refer to Figure 2 As shown, Figure 2 The figure shows a balanced topology. SW0 is the first switch, and SW1 is the second switch. CPU0 is the first processor, and CPU1 is the second processor. When the image processor topology is balanced, the first processor detects that the firmware update for the first switch has failed. The first processor notifies the second processor of the failure, which in turn notifies the second switch. The second switch then issues a restore command to the first switch, which transfers the old firmware image file to the first switch and restores the firmware based on the corresponding configuration file.

[0050] refer to Figure 3 As shown, Figure 3The figure shows a common topology. When the image processor uses the common topology, the first processor detects a firmware update failure on the first switch and notifies the second switch of the failure. The second switch then issues a restore command to the first switch. The second switch then transfers its old firmware image file to the first switch and restores the first switch's firmware according to the corresponding configuration file.

[0051] refer to Figure 4 As shown, Figure 4 This is a cascade topology. When the image processor topology is a cascade topology, the first processor detects a firmware refresh failure on the first switch. The first processor notifies the second switch of the firmware refresh failure via the first switch. The second switch issues a restore instruction to the first switch. The second switch transfers the second switch's firmware image file to the first switch and restores the first switch's firmware according to the corresponding configuration file.

[0052] This embodiment executes a corresponding firmware restoration process according to the topology of the image processor, which can better adapt to the topology of the image processor and meet the topology requirements of the image processor.

[0053] Flash the new firmware to the second switch chip (i.e., the second switch). After the flash is complete, determine whether the second switch's firmware was successfully flashed by checking the second switch's firmware version information, operating status, and other information. If the flash fails, a restore command is issued to the first switch through the first switch chip (i.e., the first switch), and the second switch's firmware is restored using the first switch's old firmware. If the second switch's firmware is successfully flashed, the new firmware image file and corresponding configuration file are retained.

[0054] In some embodiments, sending a restore instruction to the second switch and restoring the firmware of the second switch using the firmware of the first switch includes:

[0055] If the topology of the image processor is a balanced topology, the second processor notifies the first processor of a firmware update failure for the second switch, and the first processor notifies the first switch of the firmware update failure for the second switch, so that the first switch issues a restore instruction to the second switch. The first switch transfers the firmware image file of the first switch to the second switch and restores the firmware of the second switch according to a corresponding configuration file. In the balanced topology, the first processor is connected to the first switch and the second processor, the second processor is connected to the second switch, and the first switch is connected to the second switch.

[0056] If the image processor topology is a universal topology, the first processor notifies the first switch of a firmware update failure for the second switch, causing the first switch to issue a restore instruction to the second switch. The first switch transfers the firmware image file of the first switch to the second switch and restores the firmware of the second switch according to a corresponding configuration file. In the universal topology, the first processor is connected to the first switch, the second switch, and the second processor, respectively, and the first switch is connected to the second switch.

[0057] If the image processor topology is a cascade topology, the first processor notifies the first switch that the firmware update of the second switch has failed, causing the first switch to issue a restore instruction to the second switch. The first switch transfers the firmware image file of the first switch to the second switch and restores the firmware of the second switch according to a corresponding configuration file. In the cascade topology, the first processor is connected to the first switch and the second processor respectively, and the first switch is connected to the second switch.

[0058] refer to Figure 2 As shown, when the image processor topology is balanced, the second processor detects that the firmware update of the second switch has failed. The second processor notifies the first processor of the firmware update failure of the second switch. The first processor then notifies the first switch of the firmware update failure of the second switch. The first switch issues a restore instruction to the second switch. The first switch transfers the old firmware image file of the first switch to the second switch and restores the firmware of the second switch according to the corresponding configuration file.

[0059] refer to Figure 3 As shown, when the topology of the image processor is a universal topology, the first processor detects that the firmware refresh of the second switch has failed. The first processor notifies the first switch of the firmware refresh failure of the second switch. The first switch issues a restore instruction to the second switch. The first switch transfers the old firmware image file of the first switch to the second switch and restores the firmware of the second switch according to the corresponding configuration file.

[0060] refer to Figure 4 As shown, when the topology of the image processor is a cascade topology, the first processor detects that the firmware refresh of the second switch has failed. The first processor notifies the first switch of the firmware refresh failure of the second switch. The first switch issues a restore instruction to the second switch. The first switch transfers the firmware image file of the first switch to the second switch and restores the firmware of the second switch according to the corresponding configuration file.

[0061] This embodiment executes a corresponding firmware restoration process according to the topology of the image processor, which can better adapt to the topology of the image processor and meet the topology requirements of the image processor.

[0062] In some embodiments, it further includes:

[0063] detecting whether the firmware of the first switch is restored successfully;

[0064] If the firmware of the first switch is restored successfully, outputting restoration success and retaining the target indicator;

[0065] If the firmware restoration of the first switch fails, a restoration failure is output, a restoration instruction is sent to the first switch again, and the firmware of the second switch is used to restore the firmware of the first switch again; or, the firmware of the first switch is refreshed again; or, an alarm is issued to prompt manual intervention.

[0066] If the firmware restoration of the first switch is successful, a refresh success is output, and target metrics are retained for monitoring and evaluation. Target metrics may include automatic recovery time, success rate, and data integrity. Automatic recovery time can be the time from triggering the restore operation to successful restoration. If the firmware restoration of the first switch fails, a refresh failure is output, and the firmware restoration may be repeated; alternatively, the first switch may be reflashed with new firmware; or an alarm may be issued to prompt human intervention.

[0067] In some embodiments, it further includes:

[0068] If the firmware of the first switch is restored successfully, the firmware of the first switch is refreshed again.

[0069] If the firmware of the first switch is restored successfully, after confirming that the firmware version information and operating status of the first switch are normal, the new firmware is refreshed on the first switch to upgrade the firmware of the first switch.

[0070] In some embodiments, it further includes:

[0071] detecting whether the firmware of the second switch is restored successfully;

[0072] If the firmware of the second switch is restored successfully, outputting restoration success and retaining the target indicator;

[0073] If the firmware restoration of the second switch fails, a restoration failure is output, a restoration instruction is sent to the second switch again, and the firmware of the second switch is restored again using the firmware of the first switch; or, the firmware of the second switch is refreshed again; or, an alarm is issued to prompt manual intervention.

[0074] If the firmware restoration of the second switch is successful, a refresh success is output, and target metrics are retained for monitoring and evaluation. Target metrics may include automatic recovery time, success rate, and data integrity. Automatic recovery time can be the time from triggering the restore operation to successful restoration. If the firmware restoration of the second switch fails, a refresh failure is output, and the firmware restoration may be repeated; alternatively, the second switch may be reflashed with new firmware; or an alarm may be issued to prompt human intervention.

[0075] In some embodiments, it further includes:

[0076] If the firmware of the second switch is restored successfully, the firmware of the second switch is refreshed again.

[0077] If the firmware of the second switch is restored successfully, after confirming that the firmware version information and operating status of the second switch are normal, the new firmware is refreshed on the second switch to upgrade the firmware of the second switch.

[0078] In some embodiments, it further includes:

[0079] Simulate multiple scenarios in which firmware refresh fails, and detect whether the first switch and the second switch can successfully restore the firmware in each scenario.

[0080] To verify the effectiveness of firmware updates and address various issues during operation and maintenance, various scenarios of firmware update failure or firmware abnormalities during operation and maintenance are preset, such as hardware failure, firmware file corruption, and configuration errors. This verifies whether the Switch chip can be successfully restored. This ensures that the Switch chip can quickly and stably return to normal working status, avoiding any impact on business.

[0081] For example, multiple scenarios in which the firmware update of the first switch fails are simulated to verify whether the second switch can successfully restore the first switch.

[0082] Combine Figure 5 As shown, a specific implementation is described below:

[0083] After powering on the server, check the firmware version information and operating status of the two switch chips (Switch chip 1 and Switch chip 2). Confirm that they are operating normally and retain the firmware image files (F1_A and F2_A) and related configuration files (S1_A and S2_A). F1_A is the firmware image file for Switch chip 1, F2_A is the firmware image file for Switch chip 2, S1_A is the configuration file for Switch chip 1, and S2_A is the configuration file for Switch chip 2.

[0084] Use a tool in the operating system (OS) to flash the firmware of Switch chip 1. After the flash is complete, check the firmware version information and operating status of Switch chip 1. If the firmware version information and operating status are normal, the flash is successful and the new firmware image file F1_B and related configuration file S1_B are retained. If the firmware version information and configuration file are abnormal, the flash is failed and a restore operation is initiated: 1. Switch chip 2 issues a restore command to trigger the firmware restore operation. Switch chip 2 transfers the stored correct firmware image file to Switch chip 1. The firmware is restored according to configuration file S1_A, and the transfer progress and configuration status are monitored in real time to confirm the integrity and accuracy of the entire restore process. After the restore is complete, if the firmware version information and operating status are abnormal, the flash is failed and the restore operation is initiated again. After the restore is complete, if the firmware version information and operating status are normal, the flash is successful. Metrics such as the automatic recovery time, success rate, and data integrity are retained for monitoring and evaluation.

[0085] Use a tool in the OS to update the firmware of Switch chip 2. After the update is complete, check the firmware version information and operating status of Switch chip 2. If the firmware version information and operating status are normal, the update is successful and the new firmware image file F2_B and related configuration file S2_B are retained. If the firmware version information and configuration file are abnormal, the update fails and the restore operation is initiated.

[0086] Simulate chip refresh failure scenarios, such as network failure, FW file corruption, configuration errors, and high-temperature damage, to verify whether Switch chip 2 can be successfully restored. This ensures that all Switch chips can quickly and stably return to normal working conditions.

[0087] Among them, reference Figure 6 As shown in the figure, a PCIE (Peripheral Component Interconnect Express) link can be used between the CPU and the Switch chip.

[0088] This application allows for firmware updates for GPUs with dual switch chips. If one switch chip fails to update, the firmware of the other switch chip can be restored without powering off, restoring the firmware of the switch chip that failed to update. This ensures that the switch chip can function effectively even if problems arise with the switch chip's firmware update. This application also reduces costs by eliminating the need for additional hardware. It enables centralized monitoring and management of switch chips in servers such as clusters or large data centers, providing convenience, speed, and efficiency.

[0089] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.
