Abstract
A method for optimizing locations of physical data accessed by one or more client applications interacting with a storage system, with the storage system comprising at least two redundancy groups having physical memory spaces and data bands. Each of the data bands corresponds to physical data stored on several of the physical memory spaces. A virtualized logical address space includes client data addresses utilizable by the one or more client applications. A storage controller is configured to map the client data addresses onto the data bands, such that a mapping is obtained, wherein the one or more client applications can access physical data corresponding to the data bands.
