A bare-metal server of a cloud storage management system comprises a system-on-chip (Soc) and a processor. The SoC receives a volume attaching request sent by a public cloud management component of the management system. The volume attaching request includes an identifier of a system volume storing a file for starting an operating system of a bare-metal server of the management system. The SoC stores the identifier of the system volume based on the volume attaching request. When the bare-metal server of the management system is started, the bare-metal server uses the identifier of the system volume to the system volume, and starts an operating system by means of the SoC accessing the system volume.

Request processing method, system on chip, and public cloud management component

A method is implemented by a system on chip and includes: receiving a volume attaching request sent by the public cloud management component, where the volume attaching request includes an identifier of a system volume; and storing the identifier of the system volume based on the volume attaching request, where when the bare-metal server is started, the bare-metal server uses the identifier of the system volume to determine the system volume, and starts an operating system of the bare-metal server based on the system volume, and the system volume stores a file used for starting the operating system of the bare-metal server.

A system for virtual machine live migration includes a management node, a source server, a destination server, a peripheral component interconnect express (PCIe) switch, and an single root input/output virtualization (SR-IOV) network adapter, where the source server includes a virtual machine (VM) before live migration; the destination server includes a VM after live migration; the management node is adapted to configure, using the PCIe switch, a connection relationship between a virtual function (VF) module used by the VM before live migration and the source server as a connection relationship between the VF module and the destination server; and the destination server, using the PCIe switch and according to the connection relationship with the VF module configured by the management node, uses the VF module to complete virtual machine live migration. By switching the connection relationships, the system ensures that a data packet receiving and sending service is not interrupted.
