  • Patent number: 10922268
    Abstract: A computer-implemented method according to one embodiment includes identifying a request to migrate data associated with a volume from a source storage pool that has a first rank extent size to a destination storage pool that has a second rank extent size greater than the first rank extent size. Additionally, the method includes creating a correspondence between logical volume extents of the volume and physical offset locations within rank extents of the destination storage pool. Further, the method includes migrating data from one or more ranks of the source storage pool to one or more ranks of the destination storage pool, according to the correspondence between the logical volume extents of the volume and the physical offset locations within the rank extents of the destination storage pool.

  • Publication number: 20210034271
    Abstract: A method and a system for data migration on a multi-tiered storage system are provided. The method can include receiving a migration task indicating a dataset to migrate. The method can further include building a plurality of buffers onto at least one high-performance storage tier. The high-performance storage tier can be based on the read speed of that tier. The method can also include referencing a shadow mapping to locate physical data from the dataset stored on a first buffer. The method can include migrating the physical data from the first buffer to a migration destination. The method can further include deallocating the first buffer. The deallocation can allow allocation of additional physical data onto the first buffer for migration.

  • Publication number: 20200264798
    Abstract: Provided are a method, system, and computer program product in which a storage controller receives a request from a host to migrate a source dataset comprising a plurality of tracks to a cloud storage. A plurality of readers are initiated to read the plurality of tracks of the source dataset in parallel, wherein each of the plurality of readers reads different tracks from the source dataset and transmits the tracks that are read from the source dataset to a migrator. For each track received by the migrator from the plurality of readers, the track is appended sequentially to a migrate dataset to be stored in the cloud storage. Metadata that indicates a mapping of tracks of the source dataset to tracks of the migrate dataset is generated.
