Abstract: A backup power supply method is provided. After detecting a host is powered off, a power-on/off management device in the host powers off elements in the host except a processor, a memory, a backup power hard disk, and a BIOS memory; sets a power-off flag in the power-on/off management device, and sends a reboot instruction to the processor. after receiving the reboot instruction, the processor runs a BIOS program stored in the BIOS memory to initialize the elements in the host except the memory when the power-off flag is detected; store to-be-stored data of the memory into the backup power hard disk; and power off all the elements in the host.

Abstract: The technology of this application relates to a network interface card. The network interface card includes a parser and at least one shared connector. The parser receives a first SEND message that is from a host client and that corresponds to a first QP connection, and distributes the first SEND message to a first shared connector in the at least one shared connector. The first SEND message includes an RDMA operation command. The first shared connector obtains NVME information that is sent to a first controller and that corresponds to the first QP connection. The first shared connector interacts with a second controller when a disconnection event of a link between the first shared connector and the first controller is detected. The first shared connector obtains a WQE from the second controller. The first shared connector sends a first RDMA message corresponding to the first QP connection to the host client based on the WQE.
