  • Application-controlled sub-LUN level data migration
    Patent number: 10838929
    Abstract: An application programming interface (API), functioning as an interface between a storage controller and an owning application, is used to migrate, from a specified source LUN to a specified target LUN, at least one specified sub-LUN data chunk, the at least one specified sub-LUN data chunk having a predefined chunk size fixed by the storage controller. A specified total migration size is incrementally reduced by each completed migration of the at least one specified sub-LUN data chunk until the total migration size is zero and the migration is completed.
