Abstract
Methods, system and computer products for user-managed multi-path performance in balanced or unbalanced fabric configurations. Exemplary embodiments include a path priority selection method, including selecting a first I/O data path to be a highest priority path in a storage area network system, selecting a second I/O data path to be a low priority path, selecting an I/O threshold value, the I/O threshold value indicating that I/O data load is excessive, directing the load balance of I/O traffic to the first I/O data path, thereby placing the second I/O data path in a standby state, monitoring the first I/O data path, determining if the first I/O data path has reached the threshold value and performing a controlled failover of the first I/O data path to the second I/O data path when an I/O data load on the first data path has reached the threshold value.
