Embodiment Construction

[0032] The embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , the embodiment of the present application provides a computer system, including a processor 1 (for example, CPU), a first endpoint device 2 and a second endpoint device 3, wherein the first endpoint device 2 is used to assist the processor 1 in managing The computer system can also be called a coprocessor. The first endpoint device 2 can be connected to the computer system in the form of a board. In addition to the coprocessor, the first endpoint device 2 can also be integrated with a memory. Wherein, the coprocessor may be an advanced reduced instruction set computing machine (advanced reduced instruction set computing machines, ARM) chip or other chips with processing capabilities, for example, a software defined infrastructure (software defined infrastructure, SDI). The board refers to that the processor is conne...

Abstract

The invention discloses an endpoint device management method, device and system, and the method comprises the steps that a first endpoint device sends a configuration reading message comprising an identification of a second endpoint device to a first PCIe switching device, and the first endpoint device, the second endpoint device and the first PCIe switching device are connected through PCIe; then, the first endpoint device receives a health state message which is sent by the first PCIe switching device and comprises health state information of a second endpoint device and an identifier of thefirst endpoint device, and the health state information is obtained by the second endpoint device according to a configuration reading message; and the first endpoint device identifies whether the second endpoint device fails or not according to the health state message and executes corresponding processing operation, so that the reliability of the computer system is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a management method, device and system for an endpoint device in a computer system. Background technique [0002] A traditional computer system includes a processor and multiple endpoints. Communication between different endpoints is based on the peripheral component interconnect express (PCIe) standard. A single-host can be used for specific implementation. Architecture, using address-based routing to implement peer-to-peer communication between different endpoint devices. Although point-to-point technology can transmit input / output (I / O) data between endpoint devices, management data such as routing configuration and device failure notification still need to be sent to a processor (for example, a central processing unit ( Central processing unit (CPU)) in the root complex (root complex, RC), the root complex realizes the transmission of management data and the management of ...
