Abstract
The present disclosure describes aspects of cache management of logical-physical translation metadata. In some aspects, a cache (260) for logical-physical translation entries of a storage media system (114) is divided into a plurality of segments (264). An indexer (364) is configured to efficiently balance a distribution of the logical-physical translation entries (252) between the segments (252). A search engine (362) associated with the cache is configured to search respective cache segments (264) and a cache manager (160) may leverage masked search functionality of the search engine (362) to reduce the overhead of cache flush operations.
