A neighborhood matrix denoting a distribution of neighboring physical storage portions across the N physical storage devices of the pool is created and initialized. A disk extent consumed array denoting a disk consumption metric is created and initialized. Disks in an extent pool are analyzed to identify a least consumed disk in the extent pool and a disk extent is allocated from the identified disk. The allocated disk extent is configured as a first disk extent for a first RAID extent. The neighborhood matrix and disk extent consumed array are updated appropriately. All the disks in the extent pool are analyzed to identify a valid disk extent that will result in the lowest variance value in the neighborhood matrix. The identified valid disk extent is allocated and the neighborhood matrix and disk extent consumed array are again updated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Managing mapped raid extents in data storage systems","description":"A technique for use in managing mapped RAID extents is disclosed.
