Abstract: Techniques are disclosed relating to reclaiming data on recording media. In one embodiment, an apparatus has a solid-state memory array including a plurality of blocks. The solid-state memory array may implement a cache for one or more storage devices. Respective operational effects are determined relating to reclaiming ones of the plurality of blocks. One of the plurality of blocks is selected as a candidate for reclamation based on the determined operational effects, and the selected block is reclaimed. In some embodiments, the determined operational effects for a given block indicate a number of write operations to be performed to reclaim the given block. In some embodiments, operational effects are determined based on criteria relating to assigned quality-of-service levels. In some embodiments, operational effects are determined based on information relating to virtual storage units.

Abstract: A storage module may be configured to perform log storage operations on a storage log maintained on a non-volatile storage medium. An I/O client may utilize storage services of the storage module to maintain an upper-level log. The storage module may be configured to coordinate log storage and/or management operations between the storage log and the upper-level log. The coordination may include adapting a segment size of the logs to reduce write amplification. The coordination may further include coordinating validity information between log layers, adapting log grooming operations to reduce storage recovery overhead, defragmenting upper-level log data within the storage address space, preventing fragmentation of upper-level log data, and so on. The storage module may coordinate log operations by use of log coordination messages communicated between log layers.
