Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification.

It will be appreciated that since there is no operating system within the bare metal server, the bare metal server is typically managed through a data center, including out-of-band management, dedicated control card management, and the like.

The out-of-band management is to provide management capability to the outside by utilizing a baseboard management controller (Baseboard Management Controller, BMC) of the bare metal server, firstly obtain the BMC address, the user name and the password of the bare metal server, and then call an intelligent platform management interface (Intelligent Platform Management Interface, IPMI) to perform configuration management on the bare metal server;

the special control card management is to customize the special control card for the bare metal server, insert the special control card into the bare metal server, and manage the bare metal server through the special control card.

The management method has the following problems:

1. out-of-band management mainly depends on functions provided by BMCs of bare metal servers, interfaces and capabilities provided by various bare metal server manufacturers are different, unified management operation and maintenance are inconvenient, and BMCs are limited in processable scenes and have no universality.

2. The special control card management needs to customize the server, cannot be used for a general server and has high cost.

Based on the above-mentioned problems, the embodiments of the present application provide a bare metal server management method, in which a DPU is inserted into a bare metal server to implement connection between the DPU and the bare metal server, and a mapping between an Operating System (OS) image file and the bare metal server is established through the DPU, so that the bare metal server can load the Operating System in the Operating System image file, and then a management instruction is sent to the loaded Operating System through a data transmission channel between the DPU and the bare metal server, so that the loaded Operating System manages the bare metal server according to the management instruction.

First, a schematic diagram of a bare metal server management system suitable for the bare metal server management method provided in the present application is described.

Referring to fig. 1, fig. 1 is a schematic diagram of a bare metal server management system provided in an embodiment of the present application, where the bare metal server management system includes a bare metal server and a DPU, and in fig. 1, the DPU is inserted into the bare metal server to implement connection between the DPU and the bare metal server.

After the DPU is connected with the bare metal server, the DPU establishes a mapping between the operating system image file and the bare metal server, and the bare metal server can load the operating system in the operating system image file by restarting the bare metal server; and then the DPU sends a management instruction to the bare metal server through a data transmission channel between the DPU and the bare metal server, and the bare metal server is managed according to the management instruction after an operating system loaded by the bare metal server receives the management instruction.

Alternatively, the management object of the operating system loaded by the bare metal server may be a resource in the bare metal server that is not unloaded by the DPU, such as heterogeneous acceleration hardware (graphics processor (graphics processing unit, GPU) and the like), memory, local disk, network card and the like.

Referring to fig. 2, fig. 2 is a flow chart of a bare metal server management method according to an embodiment of the present application, and the DPU shown in fig. 1 is taken as an example to illustrate that fig. 2 is applied to the bare metal server management method in fig. 2 includes: S201-S202.

S201, mapping the operating system image file and the bare metal server so that the bare metal server loads the operating system in the operating system image file.

The DPU establishes a mapping between the operating system image file and the bare metal server, so that the bare metal server loads the operating system in the operating system image file, and then can manage the bare metal server through the loaded operating system, such as server baseline configuration, local disk erasure, special hardware configuration, and the like.

Optionally, the DPU may establish a mapping of the operating system image file to the bare metal server after receiving the management command for the bare metal server. For example, when a configuration instruction of a user is received and standardized configuration needs to be performed on the bare metal server, a mapping between an operating system image file and the bare metal server may be first established, so that the bare metal server loads an operating system in the operating system image file.

Optionally, the DPU establishes a mapping between the operating system image file and the bare metal server by establishing the implementation manner so that the bare metal server loads the operating system image file, and the DPU may establish a mapping between the operating system image file and the bare metal server by: if the format of the operating system image file is in a raw material (raw) format, the operating system image file can be created into an Asynchronous I/O block device (AIO bdev) through a storage performance development kit (Storage Performance Development Kit, SPDK), and then the created AIO bdev is mounted on the bare metal server to realize that the operating system image file and the bare metal server are mapped so that the bare metal server can load the operating system image file.

S202, a management instruction is sent to the bare metal server through a data transmission channel, so that an operating system loaded in the bare metal server manages the bare metal server according to the management instruction.

Alternatively, since the DPU is inserted into the bare metal server, connection between the DPU and the bare metal server is achieved through a peripheral component interconnect standard (Peripheral Component Interconnect, PCI) interface, and a data transmission channel between the DPU and the bare metal server is achieved based on the PCI interface.

Optionally, the DPU has a management plane (e.g., a management plane Agent (Agent)), where the management plane Agent may receive a management instruction sent by the bare metal management plane, and after receiving the management instruction, the management plane Agent sends the management instruction to the bare metal server through the data transmission channel.

Alternatively, the data transmission channel may be established when the DPU is plugged into the bare metal server, or when there is a data transmission requirement between the DPU and the bare metal server (e.g., when the DPU transmits management instructions to the bare metal server).

Therefore, the DPU inserted into the bare metal server loads the operating system image file through the bare metal server so as to provide the operating system with the management function for the bare metal server by establishing the mapping between the operating system image file and the bare metal server, then the DPU establishes a data transmission channel between the bare metal server and the DPU and sends a management instruction to the bare metal server through the data transmission channel, so that the operating system loaded by the bare metal server can manage the bare metal server according to the management instruction.

Further, the management method is applicable to various configuration scenes, such as management of devices which cannot be unloaded in the DPU in the bare metal server, is applicable to various bare metal servers, and has good applicability.

In an alternative implementation manner, please refer to fig. 3, fig. 3 is a schematic diagram of a bare metal server management system provided in an embodiment of the present application, where the bare metal server management system includes a DPU and a bare metal server, an operating system image file OS is stored in the DPU, the operating system image file OS includes an operating system, and the DPU establishes a mapping between the OS and a preset device (for example, a physical hard disk sda) in the bare metal server, so that the bare metal server can load the operating system in the operating system image file, and then the operating system loaded by the bare metal server is OS'.

In this way, a mapping is established between the operating system image file locally stored by the DPU and the bare metal server, so that the bare metal server loads the operating system in the operating system image file and can manage the bare metal server through the loaded operating system.

Optionally, referring to fig. 3, the dpu has a management plane Agent, where the management plane Agent receives a management instruction sent by the bare metal management plane through a private network or a public network, and after receiving the management instruction, the management plane Agent establishes a mapping between an operating system image file and the bare metal server, so that the bare metal server can load the operating system in the operating system image file.

The bare metal management surface can be deployed in a data center or a cloud computing data center, can receive a user operation request or an operation and maintenance operation request, and can manage the life cycle of a bare metal server in the data center or in an edge scene;

the management surface Agent receives the operation request of the bare metal management surface, and carries out the hanging/unloading storage, the hanging/unloading elastic network card and the server configuration management on the bare metal server through the operation request.

Referring to fig. 4, fig. 4 is a schematic diagram of a bare metal server management system provided in an embodiment of the present application, in fig. 4, the bare metal server management system includes a DPU and a bare metal server, the bare metal server management system further includes a remote storage pool, the remote storage pool is connected to the DPU, and an operating system image file is stored in the DPU, the remote storage pool provides the DPU with the operating system image file, the DPU maps the operating system image file provided by the remote storage pool with the bare metal server, so that the bare metal server can load an operating system in the operating system image file, and because the operating system image file is provided by the remote storage pool, when a user demand changes or a new demand exists for management of the bare metal server, an updated operating system image file can be obtained in real time, and then the operating system image file is shared with the DPU, so that updating of the operating system image file is realized, the DPU does not need to be changed, and updating of the operating system loaded by the bare metal server is facilitated.

Further, providing operating system image files to the DPU via the remote storage pool may take the following two ways:

mode one: the remote storage pool stores an operating system image file OS, and the remote storage pool shares the operating system to the DPU so that the DPU can establish a mapping between the operating system image file and the bare metal server, and the bare metal server can load the operating system in the operating system image system.

Optionally, the operating system is created into an operating system image file in a remote storage pool, and then the operating system image file is set to be shared through the remote storage pool, so that the DPU can access the operating system image file, and a mapping is established between the operating system image file and the bare metal server, so that the bare metal server can load the operating system in the operating system image system, and then the operating system image file is stored in the remote storage pool, and the operating system image file is the remote disk image.

Mode two: uploading the operating system image file to a preset image management service, and obtaining the operating system image file by a remote storage pool through calling a block storage interface, and mounting the operating system image file to a DPU (digital processing Unit), so that the DPU establishes a mapping between the operating system image file and a bare metal server, and the bare metal server can load an operating system in the operating system image system.

In an alternative implementation manner, after the operating system loaded in the bare metal server manages the bare metal server according to the received management instruction, the bare metal server may further send a management response to the DPU through the data transmission channel, so as to feed back a management result of the bare metal server to the DPU. And the success rate of the management of the bare metal server is improved by feeding back the management result.

In an alternative implementation, the management instructions are used to control the operating system to collect server information of the bare metal server, and then the management response carries the bare metal server information, where the bare metal server information may include a Central Processing Unit (CPU) model, a disk type size, a memory type size, a disk array (RAID) card model, GPU/neural network processor (Neural network Processing Unit, NPU) information, and other special hardware information.

In an optional implementation manner, the management instruction is used for performing standardized configuration on the bare metal server, and if the management instruction includes standardized configuration information, the bare metal server may further send a management response to the DPU through the data transmission channel, where the management response carries a standardized configuration result.

In an alternative implementation, the management instruction is used to perform hardware personalized configuration on the bare metal server, for example, a user configures a disk array (RAID) according to personal needs, and an operating system loaded by the bare metal server performs management on the bare metal server according to the management instruction.

In an alternative implementation, the management instructions are used for controlling an operating system loaded in the bare metal server to erase the local disk of the bare metal server after the local disk in the bare metal server is unsubscribed by a user in a cloud scenario. Further, after the local disk is erased, it is also used to restore the local disk to a standardized configuration.

In an alternative implementation manner, the management instruction is further used for recovering the loaded original operating system through the management instruction when the bare metal server fails, for example, when the operating system of the bare metal server fails, unloading the image file after recovery, and restarting the bare metal server to complete the restoration of the loaded operating system.

In an alternative implementation, after the DPU receives the management response sent by the bare metal server, an uninstall instruction may also be sent to the bare metal server to implement uninstallation of the operating system loaded in the bare metal server. Further, after the operating system loaded by the bare metal server is unloaded, the bare metal server can be controlled to restart, so that the bare metal server is restored to the state before the operating system is loaded.

It is easy to understand that, in order to implement data transfer between the DPU and the bare metal server, a data transmission channel may be established between the DPU and the bare metal server, and since the DPU is inserted into the bare metal server, the data transmission channel is implemented based on PCI and the implementation includes:

further, the bare metal server can write the management response into the transmission image file in the form of writing the storage disk, and the DPU can read the management response written by the bare metal server in the transmission image file, so that the transmission image file can be read.

The second implementation mode is that; referring to fig. 6, fig. 6 is a schematic diagram of a bare metal server management system provided in an embodiment of the present application, where in fig. 6, the bare metal server management system includes a DPU and a bare metal server, the bare metal server has a direct access memory (Direct Memory Access, DMA), the DMA is a memory space provided by the memory of the bare metal server based on a DMA technology, the DPU can write management instructions into the DMA, and the bare metal server can read the management instructions in the DMA to implement sending the management instructions to the bare metal server; the bare metal server may write a management response to the DMA and the DPU may read the management response in the DMA to enable the DPU to receive the management response from the bare metal server.
