摘要
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.
