System and method for reorganizing data on a disk drive to improve spatial locality

摘要

A computer-implemented method for clustering related data pages in close physical proximity to each other on a magnetic disk drive or other storage device. The method includes identifying relationships between the pages, with the relationships being established not simply by time of page access, but rather by user access patterns. The pages are clustered based on the relationships. To undertake the clustering, the pages and references can be represented and analyzed as respective vertices and edges in edge graphs.
