Abstract: According to the computer device and the configuration and management method of a computer device that are provided in the embodiments of the present invention, an SMM and a CPU are controlled to connect to a PCIE Switch at different stages of system startup, so that management of a PCIE device does not rely on involvement of the CPU of the computer device. In this way, the PCIE device can be configured and managed without involvement of an operating system of the computer device, and CPU resources are saved. Manageability of the computer device is improved, meeting a requirement of a large data center for simplifying computing device management. In addition, the PCIE device is connected to the PCIE Switch by using a downstream port, with no need to configure a special interface to connect to the SMM, thereby simplifying system configuration.

Abstract: Embodiments of the present invention provide a system and a method for transmitting data based on Peripheral Component Interconnect Express 9PCIe). The system includes: a PCIe switching network, multiple switch terminal devices, a managing unit, multiple host processing units, multiple terminal processing units, multiple hosts, and multiple terminal devices. After a PCIe data packet sent by a host is processed by a host processing unit, a new PCIe data packet that can be transmitted in a PCIe switch is constructed, and is transferred, by using a switch terminal device and a terminal processing unit, to a terminal device. The embodiments can break through a limitation about a single root node of PCIe and implement sharing of a PCIe switching network by multiple hosts.

Abstract: In a packet transmission method and an apparatus for implementing the method, packets in different groups have different source port information, and a header carried in each packet carries a write address of the packet in a memory in a destination server. In this way, the to-be-sent packets are forwarded on different paths.
