[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] A dual-node server is a server architecture that integrates two independent computing nodes. This design is often used to increase computing power, improve redundancy, and reduce space usage. Each independent computing node is usually equipped with independent CPU, memory, and storage, which enables it to handle tasks such as high-performance computing (HPC) and big data analysis. The dual-node design usually enables redundant power supplies, cooling fans, and network interfaces, which enhances the reliability of the system. The dual-node machine integrates two independent computing nodes in one chassis, saving physical space in the computer room or data center. The dual-node machine provides many advantages in terms of high-performance computing, redundancy, space saving, and easy maintenance, and is widely used in various Internet Technology (IT) backgrounds. Choosing the right dual-node server can bring higher efficiency and reduce operating costs for enterprises.

[0025] Two independent computing nodes share a set of power firmware and a power supply card, which can save space and cost. Power firmware refers to the relevant software or firmware used for PSU, which is responsible for managing and monitoring the performance and function of the power supply.

[0026] The power supply firmware can provide the following functions: 1) Power management: monitoring power output, load balancing and efficiency optimization; 2) Fault monitoring: Detect abnormal conditions in power supply operation, such as overvoltage, overcurrent or overtemperature, and take corresponding measures; 3) Remote management: supports remote monitoring and control of power supply, which is convenient for users to manage; 4) Firmware update: allows users to update the power supply firmware via the network or locally to improve functions or fix problems.

[0027] When selecting or using power firmware, you generally need to ensure its compatibility with the device and whether it meets the specific power requirements.

[0028] Currently, the dual-node server can only upgrade the power supply firmware online through node 0. If a problem occurs in node 0, the power supply firmware cannot be upgraded, which does not conform to the reliability concept of the dual-node server.

[0029] Based on this, an embodiment of the present invention provides a method, device and electronic device for online upgrading of power supply firmware of a dual-node server, which are described in detail below.

[0030] Combine the following Figure 1-Figure 3 The present invention describes a method for online upgrading of power supply firmware of a dual-node server.

[0031] Please refer to Figure 1 , Figure 1 1 is a flow chart of a method for online upgrading of power supply firmware of a dual-node server provided by an embodiment of the present invention. The method is applied to a controller such as Figure 1 As shown, the method may include step 101 and step 102.

[0032] Step 101: If a power firmware upgrade request is received from the baseboard management controllers of the two nodes of the dual-node server, the power firmware upgrade request sent by the baseboard management controller of the first node is arbitrated and released so that the baseboard management controller of the first node obtains the control authority of the power firmware, and releases the control authority of the power firmware after the power firmware upgrade is completed.

[0033] Specifically, the controller may be implemented by a complex programmable logic device (CPLD), but the present embodiment is not limited thereto.

[0034] like Figure 2 As shown, the baseboard management controllers of the two nodes of the dual-node server send a power firmware upgrade request to the controller. That is, the baseboard management controllers of the two nodes of the dual-node server compete for the control authority of the power firmware. After receiving the power firmware upgrade request sent by the baseboard management controllers of the two nodes of the dual-node server, the controller selects one of the nodes through the arbitration mechanism, that is, arbitrates and releases the power firmware upgrade request sent by the baseboard management controller of the first node.

[0035] The baseboard management controller of the first node obtains the control authority of the power supply firmware and upgrades the power supply firmware through the following steps: ① Understand the model and version: Obtain the brand, model and current firmware version of the power supply firmware through the Inter-Integrated Circuit Bus (I2CBus) to ensure that the correct power supply firmware is updated; ② Back up the current configuration: Before upgrading, record or back up the current configuration parameters (if applicable) to prevent problems from occurring and restore them; ③ The PSU manufacturer provides the latest power supply firmware version and related release notes; ④ Connect to the PSU: Use the Universal Serial Bus (USB), serial port or network interface to connect to the PSU as needed to ensure a stable connection; ⑤ Firmware upgrade tool: The baseboard management controller of the first node integrates some special software tools provided by manufacturers to upgrade the power supply firmware; ⑥ Perform the upgrade: Upload the new firmware file through the network interface of the baseboard management controller of the first node and start the upgrade process. Do not disconnect the power supply or network connection during the process; ⑦ Verify the upgrade: After the upgrade is completed, check the version number of the power supply firmware to confirm whether the upgrade is successful and check whether the various functions of the power supply are working properly; ⑧ Restore the configuration. If the configuration parameters were recorded during the backup, the configuration parameters can be restored to the power supply firmware after the upgrade. At this time, the baseboard management controller of the first node has completed the upgrade of the power supply firmware. After the upgrade of the power supply firmware is completed, the baseboard management controller of the first node releases the control authority of the power supply firmware.

[0036] Optionally, if the baseboard management controller of the first node does not obtain the brand, model and current firmware version of the power supply firmware, the power supply firmware is a key component and the baseboard management controller of the first node is not allowed to upgrade the power supply firmware, thereby avoiding power supply firmware upgrade failure.

[0037] Step 102: If the baseboard management controller of the first node does not release the control authority of the power firmware after a preset time, an interrupt signal is sent to the baseboard management controller of the second node to switch the baseboard management controller of the second node to upgrade the power firmware.

[0038] Specifically, the controller starts timing after receiving a power firmware upgrade request sent by the baseboard management controller of the first node. If the baseboard management controller of the first node has not released the control authority of the power firmware within a preset time (for example, 30 minutes), it is considered that the baseboard management controller of the first node has an abnormal occupancy problem, and the control authority of the power firmware is released, and an interrupt signal is sent to the baseboard management controller of the second node. Figure 2 The switch shown switches the baseboard management controller of the second node to upgrade the power supply firmware, so that the second node can be switched to upgrade the power supply firmware after a problem occurs in the first node.

[0039] Furthermore, when the baseboard management controller of the first node has an abnormal occupancy problem, it is prompted that the baseboard management controller of the first node fails in attempting to upgrade the power firmware, and it is recommended to check the error and handle it.

[0040] The method for online upgrading of power supply firmware of a dual-node server provided by an embodiment of the present invention, first, if a power supply firmware upgrade request sent by the baseboard management controllers of the two nodes of the dual-node server is received, that is, the two nodes jointly compete for the control authority of the power supply firmware, then the power supply firmware upgrade request sent by the baseboard management controller of the first node is arbitrated and released, that is, one of the nodes is selected through the arbitration mechanism, so that the baseboard management controller of the first node obtains the control authority of the power supply firmware, and releases the control authority of the power supply firmware after the power supply firmware is upgraded; then, if the baseboard management controller of the first node does not release the control authority of the power supply firmware after a preset time, that is, the first node has an abnormal occupancy problem, then an interrupt signal is sent to the baseboard management controller of the second node to switch the baseboard management controller of the second node to upgrade the power supply firmware; that is, after a problem occurs in the first node, the second node can be switched to upgrade the power supply firmware. Therefore, the embodiment of the present invention increases redundancy to prevent the problem that the power supply firmware cannot be upgraded after a problem occurs in the first node, thereby improving the reliability of the dual-node server.

[0041] In one embodiment, the controller maintains two identical status registers, one corresponding to each of the baseboard management controller of the first node and the baseboard management controller of the second node; the status register is used to store the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node.

[0042] In this embodiment, since the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node are stored in the same two status registers, the status register of one node no longer only stores the status of the baseboard management controller of the node. The status of the baseboard management controllers of the two nodes are no longer isolated from each other, which can greatly reduce maintenance work, thereby further improving the operation and maintenance efficiency of the data security center and reducing operation and maintenance costs.

[0043] In one embodiment, the arbitration and release of the power firmware upgrade request sent by the baseboard management controller of the first node in step 101 includes: querying the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node; if the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node are both in a non-occupied state, then arbitrating and releasing the power firmware upgrade request sent by the baseboard management controller of the first node according to the priority; the method also includes: sending an interrupt signal to the baseboard management controller of the second node, so that the baseboard management controller of the second node determines that the status of the baseboard management controller of the first node is an occupied state through the corresponding status register, and prohibits sending a power firmware upgrade request to the controller; wherein, the occupied state is used to characterize that the node is occupying the power firmware to upgrade the power firmware, and the non-occupied state is used to characterize that the baseboard management controller of the node has not sent a power firmware upgrade request or has released the control authority of the power firmware.

[0044] Specifically, Figure 3 As shown, the baseboard management controllers of the two nodes of the dual-node server send a power firmware upgrade request to the controller. The controller has an internal register (not a status register) that can record the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node. The controller queries the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node through the internal register. If the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node are both in a non-occupied state (the baseboard management controller of the node has not sent a power firmware upgrade request or has released the control authority of the power firmware), the power firmware upgrade request sent by the baseboard management controller of the first node is arbitrated and released according to the priority (the priority of the first node is greater than the priority of the second node by default), and the baseboard management controller of the first node upgrades the power firmware. An interrupt signal is sent to the baseboard management controller of the second node, and the baseboard management controller of the second node queries the status of the baseboard management controller of the first node in the corresponding status register. If the status of the baseboard management controller of the first node is in an occupied state, it means that the first node is occupying the power firmware to upgrade the power firmware, and the baseboard management controller of the second node is prohibited from sending a power firmware upgrade request to the controller, and the baseboard management controller of the second node will not try to occupy the power firmware.

[0045] In this embodiment, the baseboard management controller of one node upgrades the power firmware through a priority arbitration mechanism, and the power firmware upgrade request function of another node is disabled through an interrupt mechanism.

[0046] In one embodiment, the method also includes: if the baseboard management controller of the first node releases the control authority of the power firmware, an interrupt signal is sent to the baseboard management controller of the second node, so that the baseboard management controller of the second node determines that the state of the baseboard management controller of the first node is a non-occupied state through the corresponding status register, allowing a power firmware upgrade request to be sent to the controller; wherein the non-occupied state is used to characterize that the baseboard management controller of the node has released the control authority of the power firmware.

[0047] Specifically, if the baseboard management controller of the first node releases the control authority of the power firmware normally, an interrupt signal is sent to the baseboard management controller of the second node. The baseboard management controller of the second node queries the state of the baseboard management controller of the first node in the corresponding status register. If the state of the baseboard management controller of the first node is a non-occupied state, it means that the baseboard management controller of the first node has released the control authority of the power firmware, allowing the baseboard management controller of the second node to send a power firmware upgrade request to the controller, and the baseboard management controller of the second node can try to occupy the power firmware.

[0048] In this embodiment, when the baseboard management controller of one node has released the control authority of the power firmware, the power firmware upgrade request function of another node is enabled through an interrupt mechanism.

[0049] In one embodiment, the method further includes: if a power firmware upgrade request sent by a baseboard management controller of a second node is received, querying the status of the baseboard management controller of the first node; if the status of the baseboard management controller of the first node is an occupied state, arbitrating and intercepting the power firmware upgrade request sent by the baseboard management controller of the second node, and returning an error code to the baseboard management controller of the second node; wherein the occupied state is used to characterize that the node is occupying the power firmware to upgrade the power firmware.

[0050] Specifically, the controller has an internal register (not a status register) that can record the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node. If the controller only receives a power firmware upgrade request sent by the baseboard management controller of the second node at this time, the controller queries the status of the baseboard management controller of the first node through the internal register. If the status of the baseboard management controller of the first node is occupied, it means that the first node is occupying the power firmware to upgrade the power firmware. The controller arbitrates and intercepts the power firmware upgrade request sent by the baseboard management controller of the second node, and returns an error code to the baseboard management controller of the second node, which means that the baseboard management controller request of the second node failed.

[0051] In this embodiment, when a node is occupying the power firmware to upgrade the power firmware, the power firmware upgrade request sent by the baseboard management controller of another node is intercepted through the arbitration mechanism, and the baseboard management controller of the other node is prompted that the request fails.

[0052] In one embodiment, the method also includes: if a power firmware upgrade request sent by the baseboard management controller of the second node is received, querying the status of the baseboard management controller of the first node; if the status of the baseboard management controller of the first node is a non-occupied state, arbitrating and releasing the power firmware upgrade request sent by the baseboard management controller of the second node, and returning a correct code to the baseboard management controller of the second node, so that the baseboard management controller of the second node obtains the control authority of the power firmware, and releases the control authority of the power firmware after the power firmware upgrade is completed; sending an interrupt signal to the baseboard management controller of the first node, so that the baseboard management controller of the first node determines that the status of the baseboard management controller of the second node is an occupied state through the corresponding status register, and prohibits sending a power firmware upgrade request to the controller; wherein, the occupied state is used to characterize that the node is occupying the power firmware to upgrade the power firmware, and the non-occupied state is used to characterize that the baseboard management controller of the node has not sent a power firmware upgrade request or has released the control authority of the power firmware.

[0053] Specifically, the controller has an internal register (not a status register) that can record the status of the baseboard management controller of the first node and the status of the baseboard management controller of the second node. If the controller only receives the power firmware upgrade request sent by the baseboard management controller of the second node at this time, the controller queries the status of the baseboard management controller of the first node through the internal register. If the status of the baseboard management controller of the first node is a non-occupied state, it means that the baseboard management controller of the first node has not sent a power firmware upgrade request or has released the control authority of the power firmware. Since the baseboard management controller of the first node has not sent a power firmware upgrade request at this time, the controller arbitrates and releases the power firmware upgrade request sent by the baseboard management controller of the second node, and returns a correct code to the baseboard management controller of the second node. The baseboard management controller of the second node obtains the control authority of the power firmware, upgrades the power firmware, and releases the control authority of the power firmware after the power firmware upgrade is completed. While returning the correct code to the baseboard management controller of the second node, an interrupt signal is sent to the baseboard management controller of the first node. The baseboard management controller of the first node queries the status of the baseboard management controller of the second node in the corresponding status register. If the baseboard management controller of the second node is in the occupied state, it means that the baseboard management controller of the second node is occupying the power firmware to upgrade the power firmware, and the baseboard management controller of the first node is prohibited from sending a power firmware upgrade request to the controller, and the baseboard management controller of the first node will not try to occupy the power firmware.

[0054] In this embodiment, when a node sends a power firmware upgrade request, the baseboard management controller of the node upgrades the power firmware through an arbitration mechanism, and the power firmware upgrade request function of another node is disabled through an interrupt mechanism.

[0055] In one embodiment, the occupied state includes an applied occupied state, an upgrading state and an upgraded completed state; and further includes: when a power supply firmware upgrade request sent by the baseboard management controller of the node is arbitrated and released, the state of the baseboard management controller of the node in two identical status registers is updated to an applied occupied state, so that after the baseboard management controller of the node is restarted, when the state of the baseboard management controller of the node is determined to be an applied occupied state through the corresponding status register, the power supply firmware is upgraded; when the baseboard management controller of the node is upgrading the power supply firmware, the state of the baseboard management controller of the node in two identical status registers is updated to an upgraded state, so that after the baseboard management controller of the node is restarted, when the state of the baseboard management controller of the node is determined to be an upgraded state through the corresponding status register, the control authority of the power supply firmware is released or the user is reminded to upgrade again; when the baseboard management controller of the node has completed the power supply firmware upgrade, the state of the baseboard management controller of the node in two identical status registers is updated to an upgraded completed state, so that after the baseboard management controller of the node is restarted, when the state of the baseboard management controller of the node is determined to be an upgraded completed state through the corresponding status register, the control authority of the power supply firmware is released.

[0056] Specifically, since the baseboard management controller of the node may be restarted quickly due to other reasons, the baseboard management controller of the node can know the status of the baseboard management controller of the node before the restart through the corresponding status register. If it is in the application occupation state, it means that the power supply firmware has not been upgraded, so the power supply firmware is upgraded. If it is in the upgrading state, it means that the power supply firmware was being upgraded before the restart, and the last upgrade failed after the restart, then the control authority of the power supply firmware is actively released or the user is reminded to upgrade again, without waiting for more than the preset time (for example, 30 minutes). If it is in the upgrade completion state, it means that the power supply firmware has been upgraded before the restart, then the control authority of the power supply firmware is released immediately.

[0057] In this embodiment, after the baseboard management controller of the node suddenly and quickly restarts, different power supply firmware upgrade measures can be taken according to different states recorded in the status register, thereby further improving the reliability of the dual-node server.

[0058] The following is a description of an apparatus for online upgrading of power supply firmware of a dual-node server provided by the present invention. The apparatus for online upgrading of power supply firmware of a dual-node server described below and the method for online upgrading of power supply firmware of a dual-node server described above can refer to each other.
