Linux-IO Multipathing (LIO)

Linux-IO Multipathing (LIO) is a technology used in Linux systems to manage multiple data paths between a server and storage devices. It ensures data availability and reliability by automatically rerouting data through alternate paths if one connection fails, reducing downtime. LIO consolidates multiple physical connections into a single logical path, optimizing performance and simplifying management. Essentially, it acts as a smart traffic controller that keeps data flowing smoothly, even if some connections encounter issues, enhancing system resilience and efficiency in storage networking.
