[0003] Select the appropriate PCIe bandwidth according to actual business needs. In order to ensure high-performance transmission of PCIe signals, a PCIe Repeater adapter card is installed on the expansion port of the CPU server to realize interface conversion from PCIe connectors or OCP connectors to MiniSAS connectors. The long-distance transmission of signals provides a relay function; it is common to use Cable to interconnect the CPU server and GPU server externally; since the Cable is located outside the chassis, there is a possibility that the Cable may be pulled out. Unplugged by human error, normal business is interrupted, and non-standard hot swap may cause CPU server downtime

The invention discloses a method, a system and a device for preventing a cable from being pulled out mistakenly and a storage medium. The method comprises the following steps of judging whether buckleconnection between a buckle of a cable plug and a connector buckle is normal or not; in response to abnormal connection between the buckle of the cable plug and the buckle of the connector, sending alow-level interrupt signal to the PCH; triggering interruption of the PCH in response to the interruption signal, and starting hot plug of a PCIE link corresponding to the plug to disconnect the PCIElink; and judging whether the PCIE link is disconnected or not, and pulling out the cable in response to the disconnection of the PCIE link. According to the scheme provided by the invention, connection is established between the buckle of the cable plug and the pin of the golden finger, when the connection is abnormal, standard hot plug of a risk PCIE link is started, data transmission of a problem link is terminated, and server downtime possibly caused by violent hot plug is avoided.
Description
technical field [0001] The present invention relates to the field of servers, and more specifically, to a method, system, computer equipment and readable medium for preventing cables from being unplugged by mistake. Background technique [0002] GPU servers provide fast, stable, and flexible computing services for various scenarios such as deep learning, scientific computing, and graphics processing, and provide computing power support for the rapid development of artificial intelligence technology and the implementation of solutions; traditional rack-mounted servers can reduce the occupied space , but also limited by space, it is difficult to simultaneously plug a high-performance CPU and a high-performance GPU in a limited space and meet the heat dissipation requirements at the same time. Using Cable (cable) to connect the CPU server and GPU server externally realizes the function expansion of the traditional RACK (rack) server, which can meet the needs of some specific sc...
