Abstract: An invention is disclosed for intelligent load balancing in a mult-path computer system. Initially, an input/output (I/O) request to access the computer I/O device is intercepted. Then, to properly balance data path traffic, the number of I/O requests that have been sent along each data path of a plurality of data paths providing access to the computer I/O device is detected, and a failure probability is calculated for each data path paths based on the number of I/O requests that have been sent along each data path. A data path is then selected that has a failure probability lower than the failure probability of other data paths of the plurality of data paths and the computer I/O device is accessed using the selected data path.
