A PCIE device hot-plug identification method, system and related components

Abstract

The application discloses a method, system, electronic device and computer-readable storage medium for identifying hot plugging of PCIE devices, including: dividing the gold finger corresponding to the hot plugging signal on the PCIE device into a plurality of regions, and each region corresponds to Independent voltage; obtain the current voltage of the hot-swap circuit, the hot-swap circuit is composed of the hot-swap signal on the PCIE device and the hot-swap signal connection on the motherboard; determine the status of the PCIE device according to the current voltage, so that the PCIE controller can The device status performs corresponding operations, and the PCIE device status includes a fully in-position state, an incompletely in-position state, and a unplugged state. This application can realize the replacement of PCIE equipment under the condition that the server is working normally without power interruption, without the need for cumbersome button operations, saving operation and maintenance time and cost, and improving the reliability, ease of maintenance, redundancy and disaster recovery of the equipment ability.

Description

technical field [0001] The present application relates to the field of servers, in particular to a PCIE device hot-plug identification method, system and related components. Background technique [0002] With the gradual maturity of services such as cloud computing, AI, unmanned driving, edge computing, and assisted accelerated computing, various external cards in servers such as smart network cards and FPGAs (Field Programmable Gate Array, Field Programmable Logic Gate Array) accelerate There are more and more applications of PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) expansion devices such as graphics card, GPU (Graphics Processing Unit, graphics processing unit) accelerator card. [0003] Due to the needs of application business scenarios, when the server is running, the demand for thermal maintenance of these PCIE devices is becoming more and more common. This requires that the server cannot be shut down when the P...
