Abstract

A method for balancing workloads in media library access systems that provide multiple accessors disposed within a library. Each of the accessors is assigned a given zone of primary access wherein each of the zones of primary access has at least one boundary. Accessor usage is calculated by adding a score for each access to total accesses for each accessor. The totals are evaluated to determine that one or more of the boundaries requires adjustment and the boundaries are adjusted in accordance with the evaluation. By changing the average span of each accessor dynamically, the method can equalize the use of each accessor, minimizing library latency.
