摘要:
Managing resource reclamation in data storage systems is provided. A volume deletion metadata recorder records metadata for one or more deleted volumes. A policy engine, responsive to a predetermined policy rule, applies the policy rule to the metadata. The policy engine initiates policy-controlled data storage space reclamation for the one or more deleted volumes. A volume reclaimer, responsive to the policy engine, reclaims data storage space from the one or more deleted volumes. A resource allocator allocates the data storage space to satisfy a minimum requirement for available zeroed extents that comprise a minimum requirement to satisfy needs of late allocated storage volumes.
