Abstract
Systems and methods for reducing input/output operations in a computing system that uses a cache. Input/output operations associated with cache index lookups are reduced by tracking the location of the requested data such that the data can be invalidated without having to access the cache index. Input/output operations can be reduced by invalidating the entry in the cache index when reading the corresponding data.
