Apparatus, System, And Method For Storage Space Recovery After Reaching A Read Count Limit
US Patent:
8074011, Dec 6, 2011
Filed:
Nov 18, 2008

International Classification:
G06F 13/00
US Classification:
711103, 711153, 711165, 711202
Abstract:
An apparatus, system, and method are disclosed for storage space recovery after reaching a read count limit. A read module reads data in a storage division of solid-state storage. A read counter module then increments a read counter corresponding to the storage division. A read counter limit module determines if the read count exceeds a maximum read threshold, and if so, a storage division selection module selects the corresponding storage division for recovery. A data recovery module reads valid data packets from the selected storage division, stores the valid data packets in another storage division of the solid-state storage, and updates a logical index with a new physical address of the valid data.

International Classification:
G06F 12/16
US Classification:
711103, 711E12103
Abstract:
An apparatus, system, and method are disclosed for storage space recovery in solid-state storage. A sequential storage module sequentially writes data packets in a storage division. The storage division includes a portion of a solid-state storage. The data packets are derived from an object. The data packets are sequentially stored by order of processing. A storage division selection module selects a storage division for recovery. A data recovery module 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 marks the storage division selected for recovery as available for sequentially writing data packets in response to completing copying valid data from the storage division.

International Classification:
G06F 12/00
US Classification:
711103, 711E12009, 711E12008
Abstract:
An apparatus, system, and method are disclosed for storage space recovery. A storage division selection module selects a first storage division for recovery. The first storage division comprises a portion of solid-state storage in a solid-state storage device. A data recovery module reads valid data from the first storage division in response to selecting the first storage division for recovery. The data recovery module stores the valid data in a second storage division of the solid-state storage device. The data recovery module passes the valid data through at least a portion of a write data pipeline for the solid-state storage device without passing the valid data to a host device and/or without routing the valid data outside of a solid-state storage controller for the solid-state storage device.
