In one embodiment, the RamDisk protocol is used to define a RamDisk registration interface, and the virtual hard disk can be obtained by configuring basic attribute information in the RamDisk registration interface. As for the specific content of the basic attribute information, it can be set according to the actual situation.

In one embodiment, the basic attribute information may be: the base address, memory size and memory type of the virtual memory space. Based on this, the base address of the virtual memory space may be the initial address of an unused storage space in the memory, and the memory The size and memory type can be preset, and the unused memory space of the set size can be determined through the base address and memory size, and the memory type is used as the type of the virtual hard disk. For example: the type of the virtual memory space may be: at least one of optical drive, hard disk, network and removable disk.

The management channel can be established in advance, or the management channel can be established when the server needs to send a mirroring notification to the BMC. In one embodiment, the management channel is a channel from the server to the baseboard management controller HOST2BMC. In this application, the above HOST2BMC channel is added by improving the structure of the server and BMC itself.

In one embodiment, the image notification is used to notify the BMC to transmit the image data. Based on this, after the BMC receives the mirroring notification, it acquires the mirroring data. In another embodiment, the address corresponding to the virtual storage space formed by the virtual storage medium is carried in the image notification, so as to inform the BMC of the address used to store the image data, and after the BMC receives the image notification, the BMC will communicate with the server The data channel between sends the image data to the virtual storage medium.

As for how the BMC obtains the image data, the image data can be pre-stored in the BMC, and the BMC can also be obtained from other devices. In one embodiment, the BMC obtains the image data from the client after the BMC receives the image notification.

The medium is displayed on the installation interface in the form of boot options. When receiving the user selecting a storage medium as the boot option of the BIOS on the installation interface, the BIOS will identify the storage medium corresponding to the boot option and use the image in the storage medium to Data starts and installs.

As can be seen from the above technical solutions, after the image data is written into the virtual memory space, the installation interface is displayed, so that the user selects the storage medium on the installation interface, thereby starting and installing the image data in the storage medium, so that The image data transmission is completed before the BIOS enters the installation interface, which can reduce the time taken by the image data transmission, make the image data transmission efficient, and thereby improve the installation speed of the server system.
