Abstract
Aspects of the present disclosure disclose systems and methods for managing a level-two persistent cache. In various aspects, a solid-state drive is employed as a level-two cache to expand the capacity of existing caches. In particular, any data that is scheduled to be evicted or otherwise removed from a level-one cache is stored in the level-two cache with corresponding metadata in a manner that is quickly retrievable. The data contained within the level-two cache is managing using a cache list that manages and/or maintains data chunk entries added to the level-two cache based on a temporal access of the data chunk.
