摘要
A storage controller receives a request from a host to generate a source dataset by downloading a cloud object corresponding to the source dataset from a cloud storage. A plurality of writers that execute in parallel determines from metadata that indicates a mapping of tracks of the source dataset to tracks of the cloud object, which track of the cloud object corresponds to which track of the source dataset, to generate the source dataset from the cloud object for storing in a storage drive coupled to the storage controller.
