Abstract:
An apparatus, system, and method are disclosed for managing storage capacity recovery. A monitor module determines a workload write bandwidth for a sequential log-based data storage device. The workload write bandwidth includes a rate at which workload write operations generate reclaimable storage capacity on the data storage device. A target module determines a target reclamation write bandwidth for the data storage device. A capacity reclaim rate is associated with the target reclamation write bandwidth. The capacity reclaim rate satisfies the workload write bandwidth for the data storage device. A reclaim rate module determines a prospective reclamation write bandwidth for the data storage device, based on the workload write bandwidth, to correspond to the capacity reclaim rate associated with the target reclamation write bandwidth.
