Abstract

The present invention takes advantage of unused storage space within the ESS cells to provide for the efficient and cost effective storage of downloadable content. Specifically, the system of the present invention generally includes a download grid manager that communicates with the ESS cells. Content to be replicated to the ESS cells, and characteristics corresponding thereto, are received on the download grid manager from a content owner (or the like). Based on the characteristics, a storage policy, and storage information previously received from the ESS cells, the download grid manager will replicate the downloadable content to unused storage space within the ESS cells.
