APPARATUS, SYSTEM, AND METHOD FOR STORAGE SPACE RECOVERY IN SOLID-STATE STORAGE
摘要
An apparatus, system and method are disclosed for storage space recovery in solid-state storage 110. A sequential storage module 802 sequentially writes data packets in a storage division. The storage division includes a portion of a solid-state storage 110. The data packets are derived from an object. The data packets are sequentially stored by order of processing. A storage division.selection module 804 selects a storage division for recovery. A data recovery module 806 reads valid data packets from the storage division selected for recovery, queues the valid data packets with other data packets to be written sequentially, and updates an index with a new physical address of the valid data. The index includes a mapping of physical addresses of data packets to object identifiers. A storage division recovery module 808 marks the storage division selected for recovery as available for sequentially written data packets in response to completing copying valid data from the storage division.
