Abstract
Embodiments for efficient garbage collection in a data storage environment. In a storage system comprising multiple storage devices having respective sets of storage regions, at least one respective storage fragmentation threshold used to trigger a garbage collection operation is identified. The garbage collection operation is performed to reclaim data space in the storage system according to each of a block perspective and an area perspective. The block perspective performs the garbage collection operation on individual blocks of data and the area perspective performs the garbage collection operation on a plurality of the blocks in a respective storage region. The block perspective and the area perspective portions of the garbage collection operation are executed independently of one another.
