Detailed Description

Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.

In the related art, a BMC may be set on a motherboard of a server, fig. 1 is a schematic diagram of the BMC in the related art, and as shown in fig. 1, the BMC is used as a small system of the server independent of an operating system, and is used for remote state management and monitoring of all components of the server, and the server may control a firmware state of the server, execute a remote console instruction, power on/off operations, and the like through the BMC when the server is in a power-on/off state. The BMC operates independently without depending on a Basic Input Output System (BIOS) or an Operating System (OS) of the server, but may better interact with the BIOS and the OS to perform hardware management. The BMC can provide various interfaces for upper layer network management to inquire server information, such as interfaces of SNMP, IPMI, Restful and the like. With the continuous updating and perfection of hardware and chip technology, the BMC is also continuously following adjustment and adaptation, such as adapting a home-made chip and opening read-write interfaces of more components and more information. Meanwhile, the unification and standardization of the data interface collected by the upper network management system also promotes the continuous perfection of the BMC. After the server leaves a factory or is put into use, loading of the BMC controller is completed, if a new interface or technology of BMC is required, BMC upgrading is an essential stage, namely, the BMC upgrading technology also becomes a necessary link for accelerating the improvement of the BMC technology and realizing data collection standardization of a network manager.

In the related art, one way to upgrade the BMC is: a user connects a personal computer provided with a BMC upgrading tool to the hard tube switch on site, and the target server is controlled by the personal computer to upgrade the BMC. The defects of the BMC upgrading mode include: on one hand, the upper limit value of the number of servers which are sent by the computer for parallel upgrade at one time is about 30 servers, the upgrade time is about 10-15 minutes, and according to field investigation and verification, if the server BMC is calculated by 1500 large-scale hardware resource pools, 2 working days are needed for upgrading the server BMC in the whole pool; the number of upgrading the BMC by the server each time is limited by the network card bandwidth of the upgrading source equipment and the bottleneck of concurrent processing of tools; the preparation configuration operation before the large-scale resource pool is configured repeatedly each time, the workload is increased, and all server BMC firmware needing to be updated cannot be completed quickly and efficiently. On the other hand, the upgrading firmware and upgrading tool of the BMC are mainly issued in a centralized manner, in a serial manner or in a small-scale parallel manner, the whole resource pool cannot be completed in a parallel manner and upgraded at one time, manual operation consumes long time due to small-module upgrading, the maintenance period of the BMC is prolonged, and the effectiveness and timeliness of a network management system and service collection data are influenced. The other upgrading mode for the BMC is as follows: downloading an upgrading file and an upgrading tool required by BMC upgrading according to the parameters of the configuration file; determining upgrading command parameters through an upgrading file and an upgrading tool, and establishing a corresponding upgrading process according to the command parameters; and filtering and selecting a server node to be upgraded, and upgrading according to the server node and the upgrading process time BMC. The defects of the BMC upgrading mode include: the upgrading of the server BMC firmware depends on a third-party tool and configuration; an FTP server is required to be established firstly, a BMC upgrading tool and an upgrading file are uploaded to the FTP server, corresponding intercommunication parameters are configured on uplink network equipment, and then the BMC upgrading tool and upgrading firmware are distributed and downloaded to a server end required to be upgraded through the FTP server, so that the preparation workload before upgrading is increased, and the time consumption of the whole upgrading process is prolonged; and meanwhile, the BMC upgrading tool is issued to occupy bandwidth resources, so that the parallel upgrading speed in unit time is relatively reduced.

Based on this, in various embodiments of the invention, the BMC upgrade firmware is encapsulated in an image file; sending the image file to at least two target servers through a PXE process; the image file is used for each target server in the at least two target servers to upgrade the BMC.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

An embodiment of the present invention provides an upgrade method, which is applied to a control server, and as shown in fig. 2, the method includes:

step 201: packaging the BMC upgrading firmware in a mirror image file;

step 202: sending the image file to at least two target servers through a PXE process; the image file is used for each target server in the at least two target servers to upgrade the BMC.

Here, in step 201, the BMC upgrade firmware may refer to software for upgrading a BMC in the target server. The image file may refer to a file in a certain format, such as an IMG format, which encapsulates data corresponding to software that upgrades the BMC of the target server.

Here, in step 202, the PXE process may refer to a process for data transmission between the control server and the target server. The control server and the target servers are respectively provided with corresponding PXE processes, and after the at least two target servers respectively start the PXE processes and establish communication with the PXE processes on the control server through the own PXE processes, the control server can determine that the at least two target servers are started, so that the control server can send the image file to the at least two target servers through the own PXE processes.

In actual application, in the process of upgrading the BMCs of a plurality of target servers, the control server may package the BMC upgrade firmware into an image file, and send the image file to the plurality of target servers through the PXE process; after each of the target servers receives the image file, the operating system of the BMC can be operated in the memory by taking the image file as a medium, and the BMC is upgraded by utilizing BMC upgrading firmware contained in the image file after the operating system of the BMC is operated. In addition, in order to improve the efficiency of upgrading the BMC of the plurality of target devices, the smaller the size of the image file sent by the control server to each target server in the plurality of target servers is, the better the image file is, so that the bandwidth resource of the control server can be saved, the transmission speed of the image file is increased, and the target server can be ensured to quickly receive the image file and realize quick upgrading of the BMC.

Based on this, in an embodiment, the encapsulating the BMC upgrade firmware in an image file includes:

acquiring BMC upgrading firmware and upgrading commands;

The BMC upgrade firmware may refer to a file for upgrading a BMC of a target server. The upgrade command may be a command capable of operating the BMC to upgrade firmware, such as a command to acquire, delete, run, copy, and the like.

The image file may further include a storage directory of the BMC upgrade firmware in the target server, so that after receiving the image file, the target server may store the corresponding BMC upgrade firmware in the storage directory specified by the image file, which is convenient for the target server to perform subsequent processing on the BMC upgrade firmware.

In one example, as shown in FIG. 3, a process is described for a control server sending an image file to at least two target servers, comprising:

step 301: and the control server encapsulates the BMC upgrade firmware in the image file.

Here, a control server may be deployed prior to step 301. The control server can also be called a PXE server, and after the PXE server is built, the PXE server can be used as a fixed source device for upgrading the BMC of the target server. If the BMC firmware of at least two target servers needs to be upgraded, the PXE server can be used for upgrading at any time. If the need for upgrading the BMC firmware of at least two target servers does not exist, the PXE server can be unloaded after the target servers finish one-time upgrading of the BMC, and other functions can be realized by using the PXE server.

Here, the image file may refer to an Initrd image file.

As shown in fig. 4, the process of the control server to package the BMC upgrade firmware in the image file includes:

step 1: acquiring BMC upgrading firmware and upgrading commands;

here, it is assumed that the BMC upgrade firmware may include 3 BMC upgrade firmware, a BMC upgrade firmware a, a BMC upgrade firmware b, and a BMC upgrade firmware c. The upgrade command may be a command capable of operating the BMC to upgrade firmware, such as a command to acquire, delete, run, copy, and the like.

Step 2: packaging the BMC upgrading firmware and the upgrading command in a mirror image file;

here, a correspondence between the BMC upgrade firmware and the upgrade command may be established, and the BMC upgrade firmware and the upgrade command may be encapsulated in an image file based on the established correspondence.

Table 1 shows the correspondence between the BMC upgrade firmware and the upgrade command, and as shown in table 1, the upgrade command corresponding to the BMC upgrade firmware a is copied and run; the upgrading command corresponding to the BMC upgrading firmware b is copying and running; and the upgrading command corresponding to the BMC upgrading firmware c is copying and running. The copying may refer to executing a copying operation on the corresponding BMC upgrade firmware after the target server runs the operating system of the BMC in the memory using the image file as a medium, and the running may refer to executing a running operation on the corresponding BMC upgrade firmware after the target server runs the operating system of the BMC in the memory using the image file as a medium.

		BMC upgrade firmware c	Copy, run

TABLE 1

Step 302: when at least two target servers start the PXE process and communicate with the PXE process of the control server, the control server sends the image file to the at least two target servers through the PXE process.

Here, after at least two target servers start the PXE process and communicate with the PXE process of the control server, the control server may discover the at least two target servers and send the image file to the at least two target servers through the PXE process.

Here, after receiving the Initrd image file sent by the control server, the target server may load the Initrd image file in a small memory system of the target server, and store the BMC upgrade firmware encapsulated in the image file in a storage directory specified by the Initrd image file, such as a folder a of a c-disk.

Here, deploying one control server, the control server sends the image file to at least two target servers through the PXE process, has the following advantages:

(1) by utilizing a distributed and parallel upgrading mode, a control server is deployed for a large-scale resource pool formed by at least two target servers, the control server can directly transmit the image file to the at least two target servers through the PXE process after the PXE process is started by the at least two target servers and the control server is communicated with the control server, and compared with the mode that the upgrading time is long and the large-scale parallel upgrading cannot be realized due to the fact that a user carries out BMC upgrading on the target servers through a personal computer on the spot in the related technology, the large-scale resource pool can be upgraded in a batch and parallel mode through the deployed control server, so that labor and time cost are saved, the upgrading time of the BMC by the at least two target servers can be greatly shortened, and the upgrading efficiency is improved.

(2) Because the image file consists of the BMC upgrading firmware and the upgrading command, the bandwidth resource of the control server can be saved in the process that the control server sends the image file to the at least two target servers, so that the transmission speed of the image file is increased, and the upgrading speed of the at least two target servers to the BMC is increased.

(3) The method comprises the steps that a local upgrading mode is adopted, namely, after at least two target servers respectively start PXE processes and communicate with a control server through the respective PXE processes, the control server can find that the at least two target servers are started in batches, and parallelly distribute image files to the at least two target servers, and compared with a mode that corresponding intercommunication parameters need to be configured on uplink network equipment due to the fact that BMC upgrading firmware and upgrading tools are downloaded through extra-deployed TFTP servers in the related technology, the target servers can ask for the image files to the control server by starting the local PXE processes, and do not need to configure extra intercommunication parameters related to the TFTP servers on the uplink network equipment, so that the upgrading process is simplified, and simplification and optimization are carried out on the aspects of equipment and configuration; and an additional remote pulling and upgrading tool is not needed, so that excessive resources of the server are not occupied.

In practical application, the control server can realize batch upgrading for a plurality of target servers, and the models or manufacturers of the plurality of target servers can be the same or different. If the models or manufacturers of the target servers are the same, determining the same BMC upgrading firmware for the target servers, and generating an image file based on the determined BMC upgrading firmware; if the models or manufacturers of the target servers are different, determining a BMC upgrading firmware for each of the target servers to obtain a plurality of BMC upgrading firmware, and generating an image file based on the determined BMC upgrading firmware; after receiving the image files, the target servers can search the BMC upgrading firmware matched with the models of the target servers from the image files.

Based on this, in an embodiment, the obtaining the BMC upgrade firmware and the upgrade command includes:

Here, for at least two target servers of the same model, the searched upgrade command may be a unified upgrade command; aiming at least two target servers with different models, the searched upgrading command can be a uniform upgrading command or different upgrading commands.

In an embodiment, the encapsulating the BMC upgrade firmware and the upgrade command in an image file includes: and packaging the BMC upgrading firmware and the upgrading command corresponding to the determined model in an image file.

For example, for three target servers, namely, a target server a, a target server b and a target server c, assuming that the models of the target server a, the target server b and the target server c are different, the searched BMC upgrade firmware corresponding to the target server a is BMC upgrade firmware a, the searched BMC upgrade firmware corresponding to the target server b is BMC upgrade firmware b, the searched BMC upgrade firmware corresponding to the target server c is BMC upgrade firmware c, and the searched upgrade command is a uniform upgrade command.

In one example, as shown in fig. 5, a process is described for a control server to encapsulate BMC upgrade firmware in an image file, including:

step 501: the control server determines the models respectively corresponding to the at least two target servers;

here, before step 501, a control server, which may also be referred to as a PXE server, may be deployed, and after the PXE server is built, the PXE server may be used as a fixed source device for upgrading the BMC of the target server. If the BMC firmware of at least two target servers needs to be upgraded, the PXE server can be used for upgrading at any time. If the need for upgrading the BMC firmware of at least two target servers does not exist, the PXE server can be unloaded after the target servers finish one-time upgrading of the BMC, and other functions can be realized by using the PXE server.

Step 502: searching the BMC upgrading firmware corresponding to the determined model from the corresponding relation between the server model and the BMC upgrading firmware; and searching the upgrading command corresponding to the determined model from the corresponding relation between the server model and the upgrading command.

Here, table 2 shows the correspondence between the server model, the BMC upgrade firmware, and the upgrade command, and as shown in table 2, assuming that the models of the target servers are the same, that is, the target servers all belong to the vendor a, the BMC upgrade firmware b, the BMC upgrade firmware c, and the corresponding upgrade command are obtained. Assuming that the types of the target servers are different, that is, a part of the target servers belongs to a manufacturer a and a part of the target servers belongs to a manufacturer B, obtaining a BMC upgrade firmware a, a BMC upgrade firmware B, a BMC upgrade firmware c, a BMC upgrade firmware e, a BMC upgrade firmware f, and corresponding upgrade commands.

Model of Server	BMC upgrade firmware	Upgrade order
			Manufacturer A	BMC upgrade firmware a, b, c	Copy, run, delete
Manufacturer B	BMC upgrade firmware e, f	Copy, run, delete
			Manufacturer C	BMC upgrade firmware g, p, r	Copy, run, delete

TABLE 2

Step 503: and packaging the BMC upgrading firmware and the upgrading command corresponding to the determined model in an image file.

Here, assuming that the models of the plurality of target servers are the same, that is, the plurality of target servers all belong to the manufacturer a, the BMC upgrade firmware b, the BMC upgrade firmware c, and the corresponding upgrade commands are acquired, and the acquired BMC upgrade firmware and the upgrade commands are packaged in one image file.

Here, assuming that the models of the plurality of target servers are different, that is, a part of the plurality of target servers belongs to a manufacturer a and a part of the plurality of target servers belongs to a manufacturer B, obtaining a BMC upgrade firmware a, a BMC upgrade firmware B, a BMC upgrade firmware c and a corresponding upgrade command, and packaging the BMC upgrade firmware and the upgrade command corresponding to the manufacturer a in a mirror image file; and acquiring the BMC upgrading firmware e, the BMC upgrading firmware f and a corresponding upgrading command, and packaging the BMC upgrading firmware and the upgrading command of a corresponding manufacturer B into another image file. After the control server sends the two image files to the plurality of target servers, each server in the plurality of target servers can select an image file matched with the model of the server from the received two image files.

Here, the control server encapsulates the BMC upgrade firmware in an image file according to the model of the target server, which has the following advantages:

the BMC upgrading method and the system have the advantages that the corresponding BMC upgrading firmware can be matched and packaged into the image file aiming at the target servers of different models to support BMC upgrading of the target servers, namely, the control server can package the BMC upgrading firmware according to the models of the target servers to obtain the corresponding image file, the target servers can select the BMC upgrading firmware matched with the models of the target servers from the received image files according to the models of the target servers, BMC upgrading of the target servers of different manufacturers is achieved, the application range is wider, and higher usability and reliability are achieved.

In practical application, in the process that the control server upgrades the BMCs of the target servers, if the BMCs of the target servers are upgraded frequently, the control server may send a preset program to the target servers to avoid the occurrence of the situation that the target servers still upgrade the BMCs by using the image files under the condition that the version of the BMC upgrade of the target servers is the latest version, where the preset program may determine whether the version of the BMC upgrade firmware delivered to the target servers is the same as the preset version in the current target servers, and if so, the BMCs are not upgraded; otherwise, upgrading the BMC by using the received image file.

Based on this, in an embodiment, the sending the image file to at least two target servers through the PXE process includes:

Here, the preset version information may refer to version information of the current BMC upgrade firmware in the target server.

In one example, as shown in fig. 6, a process is described for a control server to send an image file to at least two target servers, including:

step 601: and the control server encapsulates the BMC upgrade firmware in the image file.

Here, before step 601, a control server, which may also be referred to as a PXE server, may be deployed, and after the PXE server is built, the PXE server may be used as a fixed source device for upgrading the BMC of the target server. If the BMC firmware of at least two target servers needs to be upgraded, the PXE server can be used for upgrading at any time. If the need for upgrading the BMC firmware of at least two target servers does not exist, the PXE server can be unloaded after the target servers finish one-time upgrading of the BMC, and other functions can be realized by using the PXE server.

Step 602: carrying a preset program in a mirror image file;

the preset program is used for comparing the version information of the BMC upgrading firmware contained in the image file with preset version information to obtain a comparison result; and when the comparison result represents that the version information of the BMC upgrading firmware is different from the preset version information, upgrading the BMC by using the image file.

Here, the preset program needs to be set to start up automatically, that is, after the target server is started up, if an image file carrying the preset program and sent by the control server is received, the preset program can be automatically executed without user involvement.

Step 603: and sending the image file to at least two target servers through the PXE process.

Here, the control server carries the preset program in the image file and sends the preset program to the at least two target servers, and the method has the following advantages:

after the control server carries the preset program in the image file and sends the image file to at least two target servers, the target servers can execute the preset program to judge whether the version of the BMC upgrading firmware sent to the target servers by the control server is the same as the preset version in the current target servers, and if the version of the BMC upgrading firmware is the same as the preset version in the current target servers, the BMC is not upgraded; otherwise, upgrading the BMC can avoid the situation that the resource consumption is overlarge because the target server still executes the image file when the BMC upgrading version of the target server is the latest version.

By adopting the technical scheme of the embodiment of the invention, one control server is deployed, and the control server directly sends the image file to at least two target servers through a PXE process; the image file is used for each target server of the at least two target servers to upgrade the BMC, and compared with a mode that in the related technology, when a user upgrades the BMC of the target servers through one personal computer on the spot, the upgrading time is longer, and the small-batch upgrading is realized, the batch parallel upgrading aiming at a large-scale target server can be realized, the upgrading time can be shortened, and the upgrading efficiency is improved.

Correspondingly, an embodiment of the present invention provides an upgrade method, which is applied to a target server, and as shown in fig. 7, the method includes:

step 701: receiving a mirror image file sent by a control server through a PXE process; the mirror image file is packaged with BMC upgrading firmware;

step 702: and upgrading the BMC by using the mirror image file.

Here, in step 701, the target server is used as a device to be upgraded, and after a large-scale resource pool, that is, a plurality of target servers are started in batch and start the PXE process, the control server can establish communication with the plurality of target servers through its own PXE process, and send an image file encapsulating the BMC upgrade firmware to the plurality of target servers in parallel.

In practical application, in order to avoid the situation that the target server still utilizes the image file to upgrade the BMC when the upgrading version of the BMC of the target server is the latest version, the control server can send a preset program to the target server, the preset program can judge whether the version of the BMC upgrading firmware sent to the target server is the same as the preset version in the current target server, and if the version of the BMC upgrading firmware sent to the target server is the same as the preset version in the current target server, the BMC is not upgraded; otherwise, upgrading the BMC by using the received image file.

Based on this, in one embodiment, the image file includes a preset program; before the BMC is upgraded by using the image file, the method further comprises:

executing the preset program to realize that:

In practical application, when the version of the BMC upgrading firmware issued to the target server is judged to be different from the preset version in the current target server through the preset program, the BMC is upgraded by using the received image file.

Based on this, in an embodiment, the image file includes a BMC upgrade firmware and an upgrade command; the upgrading of the BMC by using the image file comprises the following steps:

Here, the Redfish interface may be a standard interface of the BMC of the target server.

Here, the BMC of the target server may send a post request to the modem of the target server through a Redfish interface to request to acquire the image file, and upgrade the BMC using the BMC upgrade firmware and the upgrade command encapsulated by the image file. The main content of the post request can be mainly 'https:// device _ ip/redfish/', and the header and the message body of the post request are not added.

In an example, as shown in fig. 8, a process of upgrading a BMC by a target server using the image file is described, including:
