Storage path optimization for SANs

Embodiments of a system and method for rule-based proactive storage path optimization for SANs. Embodiments may evaluate paths between an application and its storage on a SAN based on current and/or historical path quality of service. Performance of alternative paths may be monitored to determine if a better path than a path currently in use is available. If a better path is determined, then the path may be switched to the better path. In one embodiment, one or more zones may be reconfigured to migrate to a different path. Path migration may be performed automatically without user intervention. Alternatively, a user may be given the option to manually migrate to a new path. Embodiments may proactively change paths between an application and its storage before path performance becomes a problem. Embodiments may be integrated with a SAN management system or, alternatively, may be standalone mechanisms.
