摘要
A computer-implemented method for thin provisioning using cloud based ranks comprises determining a total amount of unused physical storage space for all of a plurality of local ranks associated with a storage controller; comparing the total amount of unused physical storage space to a first threshold; in response to determining that the total amount of unused physical storage space is less than the first threshold, creating one or more cloud based ranks. Creating each of the one or more cloud based ranks comprises allocating storage space on one or more corresponding cloud storage devices via a cloud interface; mapping the allocated storage space to corresponding virtual local addresses; and grouping the virtual local addresses as a virtual local rank associated with the storage controller.
