Abstract
The subject disclosure is generally directed towards load balancing between storage processors based upon dynamic redirection statistics, in which load balancing includes changing a preferred path/a mounted file system from one storage processor to another. In one example, load balancing technology compares a current delta of directed and redirected I/O counts to a previous delta. If the result turns from negative to positive, that is, redirection is becoming prevalent, a load balancing threshold may be changed based upon the current delta value. Load balancing is thus based on the latest trend of I/O redirection.
