[0056] The exemplary embodiments will be described in detail herein with reference to the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present description.

[0057] The present application provides a component upgrade method, applied to a management controller in a server, as shown in Figure 1 , comprising:

[0058] S100, in the server startup process, a virtual storage medium is created in the server, and an access channel to the virtual storage medium is established.

[0059] As shown in Figure 2 , the motherboard in the server can be provided with a processor, a management controller and a boot chip, the processor, the management controller and the boot chip are connected through a bridge chipset (not shown), such as a south bridge chipset and a north bridge chipset, the management controller can be connected to the components based on the I 2 C bus. The management controller can be connected to component 1 and component 2 through the PCIE bus. The management controller can be a BMC (Baseboard Management Controller). Based on the configuration, the management controller can create a virtual storage medium in the server, such as a USB (Universal Serial Bus) and an optical drive, etc. The boot chip can be a BIOS (Basic Input Output System), etc. Among them, an access channel is established for the virtual storage medium, such as if the created virtual storage medium is a USB, the access channel can be a USB access channel.

[0060] The creation process can be based on the preset function of the management controller. For example, the creation process can be based on the pre-configuration, the management controller creates a virtual USB, sets the state of the virtual USB through a state parameter, and sets the state of the virtual USB as connected. So that the boot chip in the server can scan the virtual USB in the self-checking process. Thereafter, a part of the storage space in the memory of the management controller is divided, and the connection between the management controller and the processor is established through the USB bus of the south bridge chipset, that is, the management controller and the processor are connected through the access channel.

[0061] In this way, in the process of starting the server, the boot chip can scan the virtual USB in the self-checking process as the USB of the server itself, and allocate a storage space for the USB in the memory corresponding to the processor, so that the storage space divided by the management controller itself can interact with the storage space of the memory corresponding to the processor.

[0062] S101, if a read request sent by the processor in the server to the virtual storage medium is received, the system image corresponding to the read request is obtained from the preset remote device.

[0063] In the process of starting the server, according to the setting of the management controller, the processor can be guided to load the operating system from the virtual storage medium, at this time, the processor will send a read request to the virtual storage medium. When the read request is sent to the management controller through the access channel, the management controller can determine that the read request accesses the virtual storage medium based on the analysis of the read request. Then, the management controller can determine that the processor needs to be started and needs to obtain the system image required for starting.

[0064] Thereafter, the management controller can access the remote device based on the pre-configuration. The specific access mode can be that a mapping relationship between an address in the virtual storage medium and a storage space of the remote device is established in the management controller. Through the mapping relationship, the management controller can request the system image from the remote device through the communication protocol adapted to the remote device. The communication protocol can be TCP / IP protocol (Transmission Control Protocol / Internet Protocol), etc., which is not limited, as long as the management controller can communicate with the remote device.

[0065] S102, the received system image is sent to the memory corresponding to the processor, so that the processor in the server starts based on the system image, and upgrades the components deployed in the server according to the upgrade file contained in the system image.

[0066] The system image can be a small operating system, which contains a boot program, a kernel program, and an upgrade file for implementing component upgrade, etc. The system image comes from a remote device for managing and controlling the server, such as a KVM (Keyboard Video Mouse) device, or other management devices connected to the server through a network.

[0067] The boot program is used for automatic detection and register setting during server restart, such as UEFI (Unified Extensible Firmware Interface), PXE (Preboot eXecution Environment), and BIOS programs. The kernel program can be a driver (such as a PCIE driver) and a management tool for connecting components. The upgrade file is a file for upgrading firmware in the component, which needs to be transmitted to the component to enable the component to load the upgrade file during server component upgrade.

[0068] The system image can also contain an upgrade script, which can be used to implement related execution steps and related configurations during server startup.

[0069] Of course, the system image can also contain other files, configurations, and drivers to enable the server to load and execute the system by loading the contents in the system image, and to perform component upgrade, etc.

[0070] After the management controller in the server receives the system image, the system image can be sent to the memory corresponding to the processor through the access channel. In this way, during server startup, the processor can load the system image from the memory to form a small operating system, identify the components deployed in the server through the upgrade script, find the corresponding upgrade file in the system image and issue it, so that the components can be upgraded based on the issued upgrade file.

[0071] Optionally, after the system image received in step S101 is mounted to the virtual storage medium, the method further includes:

[0072] S103, receiving the upgrade log generated by the processor, and sending the upgrade log to the remote device.

[0073] When the system image is sent to the server by the remote device, in order to enable the remote device to understand the upgrade situation of the components in the server, the upgrade situation of the server can also be recorded. For example, Figure 2As shown, when the two components 1 and 2 that need to be upgraded are set in the server, after the upgrade process is performed, whether the components have completed the upgrade or the upgrade has failed can be recorded, for example, component 1 has completed the upgrade, and component 2 has not completed the upgrade, and the processor of the server can record this through the upgrade log, that is, the upgrade log can record the correspondence between the component identifier, slot and upgrade result of the component.

[0074] After the server completes the upgrade process, the processor can feed back the upgrade log to the management controller for recording, and return the upgrade log to the remote device through the management controller. In this way, after the remote device receives the upgrade log, the upgrade log can be displayed to enable the remote staff to know the upgrade component situation, thereby performing the next operation, and the efficiency of remote server maintenance and upgrade is improved.

[0075] Correspondingly, the application provides a component upgrade method applied to a processor in a server, which comprises the steps of Figure 3 As shown, comprising:

[0076] S300, in the server starting process, a read request is sent to the virtual storage medium in the server through the established access channel.

[0077] When the server starts, the boot chip performs scanning to detect the current various devices on the server, such as USB, optical drive and hard disk, and divides a plurality of storage spaces in the memory corresponding to the processor to realize the mapping of the devices. The virtual storage medium created by the management controller can also be detected as a device, and is allocated a storage space in the memory.

[0078] In the boot chip, the priority of the storage medium used for system startup can also be configured, in order to enable the virtual storage medium to be started, the priority of the virtual storage medium can be set to be higher than that of other storage media.

[0079] Due to the creation of the management controller, the virtual storage medium will be considered as an entity device connected to the server by the boot chip and the processor, at this time, the processor can send a read request based on the access channel between the virtual storage medium.

[0080] S301, acquiring a system image corresponding to the read request, and upgrading the components deployed in the server through the upgrade file acquired from the system image.

[0081] When the management controller receives a read request to access the virtual storage medium, the management controller can obtain a system image from the remote device based on the pre-setting and send the system image to the memory corresponding to the processor, so that the processor loads the system image. The system image is similar to a small operating system, and after the small operating system is loaded, the components can be upgraded through the small operating system. Since the system image has been sent to the memory corresponding to the processor, the upgrade here can be an upgrade operation based on an in-band channel, without the need to connect the channel between the processor and the components through the management controller based on a management protocol (such as the MCTP protocol).

[0082] The specific upgrade process can be as follows: S301, upgrading the components deployed in the server through the upgrade file obtained in the system image, including:

[0083] S301A, obtaining the component identifier of the component deployed in the server.

[0084] After the processor loads the small operating system, the management controller can detect the components deployed in the server and determine the slot positions of the components and the component identifiers of the components. The component identifier can be pre-set according to the function of the component, such as component identifier 1 indicating that the component is a network card and component identifier 2 indicating that the component is a hard disk management card.

[0085] S301B, searching for a corresponding upgrade file in the system image according to the component identifier.

[0086] After obtaining the component identifier, the processor can search in the system image according to the component identifier, so as to find the upgrade file corresponding to the component identifier. For example, component identifier 1 corresponds to upgrade file 1, and component identifier 2 corresponds to upgrade file 2.

[0087] S301C, issuing the found upgrade file to the corresponding component for upgrade.

[0088] After the corresponding upgrade file is found, the processor can connect the processor and the component through the in-band channel by running the small operating system, and issue the upgrade file to the corresponding component through the in-band channel, so that the component receiving the upgrade file can perform firmware upgrade.

[0089] S302, after the upgrade is completed, disconnecting the access channel of the virtual storage medium and restarting the server.

[0090] After the component to be upgraded completes the upgrade execution and feeds back the notification of completion of the upgrade to the processor, the processor determines whether all the components have completed the upgrade operation.

[0091] After determining that all the components that need to be upgraded have fed back the notification of completion of upgrade, the processor can disconnect the access channel of the virtual storage medium. The way of disconnecting the access channel can be to eject the created virtual storage medium. In addition, the processor can also complete the above disconnection operation through the management controller.

[0092] After disconnection, the server is restarted again. Since the access channel of the virtual storage medium has been disconnected, the virtual storage medium will not be detected by the boot chip, at this time, the server is restarted based on the operating system in the server, so that the server returns to normal work.

[0093] The technical solutions provided by the embodiments of the present specification can include the following beneficial effects:

[0094] In the embodiments of the present specification, by creating a virtual storage medium in the server and establishing an access channel with the virtual storage medium, when receiving a read request of the virtual storage medium by the processor, the system image is obtained from the remote device, the processor is started according to the system image, and the components deployed in the server are upgraded based on the upgrade file contained in the system image, so that the server can issue the upgrade file to the components through the loaded system after loading the system in the system image, avoiding the need for the management controller to issue the upgrade file based on the management protocol, and improving the flexibility of upgrading the components in the server.

[0095] Optionally, the method further comprises:

[0096] S303, after the upgrade is completed, an upgrade log is generated and sent to the management controller.

[0097] In the upgrade log, the component identifier of the component that completes the upgrade is recorded.

[0098] After receiving the notification of completion of upgrade or the notification of failure of upgrade fed back by the component, the processor can record the correspondence between the component identifier, the slot and the upgrade result of the component based on the notification of completion of upgrade, that is, generate an upgrade log. Through recording, the processor can know which components complete the upgrade and which components have errors in the upgrade process.

[0099] After the processor generates the upgrade log, the upgrade log can be issued to the management controller for storage, so that the management controller can display based on the upgrade log to enable the staff to determine the upgrade status of each component. Moreover, if the system image comes from a remote device, the management controller can also return the upgrade log to the remote device, so that the staff operating the remote device remotely can know the upgrade result of the component, thereby improving the efficiency of remote upgrade of the server.
