Abstract
A data storage system is disclosed that utilizes a high performance caching architecture. In one embodiment, the caching architecture utilizes a cache table, such as a lookup table, for referencing or storing host data units that are cached or are candidates for being cached in the solid-state memory. Further, the caching architecture maintains a segment control list that specifies associations between particular cache table entries and particular data segments. Such separation of activities related to the implementation of a caching policy from activities related to storing cached data and candidate data provides robustness and scalability while improving performance.
