Abstract
A system analyzes access patterns in a storage system. Logic circuitry in the system identifies different address regions of contiguously accessed memory locations. A statistical record identifies a number of storage accesses to the different address regions and a historical record identifies previous address regions accessed prior to the address regions currently being accessed. The logic circuitry is then used to prefetch data from the different address regions according to the statistical record and the historical record.
