Most storage devices support multiple SAN connections for performance and reliability, but in many configurations servers use only a single storage connection. This creates a single point of failure and potential performance bottleneck for I/O. Multipath Input/Output (MPIO) is server software that extends redundancy to the entire I/O pathway in a SAN, delivering fault tolerance, high availability, and better performance.
