Multipath I/O (MPIO)

Multipath I/O (MPIO) is a technology that allows a computer or server to access storage devices through multiple communication paths simultaneously. This ensures reliable data transfer, as if one path fails, others can take over seamlessly. It improves fault tolerance and performance by distributing data loads across multiple routes. Think of it like multiple roads leading to the same destination—if one road is blocked, traffic automatically switches to an alternative, maintaining smooth, continuous access to stored data without interruption.
