Abstract: Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes.

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.

Abstract: Aspects of the present disclosure disclose systems and methods for recognizing multiple and distinct references within a cache that identify or otherwise provide access to empty blocks of data. Multiple references identifying empty blocks of data are associated with a single block of empty data permanently stored in the cache. Subsequently, each time an empty block of data is added to the cache, a reference corresponding to the empty block is mapped to a generic empty block of data stored in the cache. When a reference is removed or deleted from the cache, only the reference is deleted; the single generic block of empty data continues to reside in the cache.
