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.

摘要： 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.
摘要翻译：存储模块可以被配置为对保存在非易失性存储介质上的存储日志执行日志存储操作。 I / O客户端可以利用存储模块的存储服务来维护上级日志。存储模块可以被配置为协调存储日志和上级日志之间的日志存储和/或管理操作。协调可能包括调整日志的段大小以减少写入放大。协调可以进一步包括协调日志层之间的有效性信息，适应日志修饰操作以减少存储恢复开销，对存储地址空间内的上层日志数据进行碎片整理，防止上级日志数据的分段等。存储模块可以通过使用在日志层之间传送的日志协调消息来协调日志操作。
