PathManager
PathManager enables multi-pathing for failover and load balancing. Up to 32 physical connections or logical data paths between a server and an array are utilized to provide higher reliability and performance. Clustered servers are also supported.

PathManager provides the following functions:
Path failover
If a data path is no longer accessible, an alternative path is used, enabling non-disruptive operations in the event of a failure.
Static load balancing
Assign a specific path to be used when accessing a particular LUN.
Dynamic load balancing
Dynamically select which path to use based on various criteria to increase performance.
Path health and configuration check
Monitors the paths for failures and misconnected FC cables. Checks failed paths for restoration.
