  • Moving data among disk slices located in different disk groups of at least one storage array
    Patent number: 11709595
    Abstract: A technique for storage management involves: determining multiple source disk slices from a storage array that provides redundant storage, a current disk group where each of the multiple source disk slices is located being different from a target disk group where the source disk slice is specified to be located; determining multiple destination disk slices from the target disk group based on the multiple source disk slices, the multiple destination disk slices being used to replace the multiple source disk slices; and causing data to be moved to the multiple destination disk slices from the multiple source disk slices. Accordingly, such a technique may improve the reliability of a storage system.
