Latest Patents
Among his latest patents is a system and method for cache replacement using an access-ordering lookahead approach. This invention addresses the challenges of accessing files stored in a storage system by retrieving data objects associated with the file from a storage device. The data objects are then cached in a cache memory. Qian's method determines an access sequence of the cached data objects based on the file's metadata, which represents the order in which the cached data objects are accessed over time. When a request for cache space reclamation arises, the system identifies cached data objects whose next access is the farthest in time from the currently accessed data object. This allows for efficient eviction of data objects from the cache memory, optimizing storage performance.
