AI Technical Summary
Technical Problem
Existing technologies cannot effectively monitor and handle faults in RDMA network protocol network cards, leading to data delays, inconsistencies, and link failures, which affect business operations.
Method used
By polling and monitoring the asynchronous events and completion queue events of the target network card, analyzing the event type information, determining the network card's fault status, and sending fault messages, performing hot-swapping operations, or switching to redundant links when a fault occurs, automatic fault handling is achieved.
Benefits of technology
It enables automatic monitoring and handling of network card failures in the RDMA network protocol, improving the stability of the network card link and ensuring the normal operation of services.

Abstract
This invention provides a method and apparatus for determining network interface card (NIC) faults. The method includes: polling and monitoring asynchronous events and completion queue events of the target NIC; determining the event type information of the asynchronous events and the event type information of the completion queue events; and determining the fault state of the target NIC based on the event type information of the asynchronous events and / or the event type information of the completion queue events. The NIC fault determination method and apparatus provided by this invention, by polling and monitoring asynchronous events and completion queue events of the target NIC, and determining the fault state of the target NIC based on the event type information of the asynchronous events and / or the event type information of the completion queue events, achieves automatic determination of whether the target NIC is in a fault state based on the monitoring of target NIC events. This provides a foundation for subsequent targeted fault handling of the target NIC based on its fault state, improving the stability of the target NIC link.
