ABSTRACT:
Embodiments of the present invention provide techniques for distributing the reconstruction process of a failed storage device in an array of storage devices to storage systems in a storage system cluster (cluster). The inventive technique includes a storage system securing the array, decomposing the reconstruction process into a number of tasks, distributing each task to other storage system in the cluster, and reconstructing data using results of the tasks performed by the other storage systems.
