Data-aware cache state machine
Management of a Cache is provided by differentiating data base on attributes associated with the data and reducing storage bottlenecks. The Cache differentiates and manages data using a state machine with a plurality of states. The Cache may use data patterns and statistics to retain frequently used data in the cache longer. The Cache uses content or attributes to differentiate and retain data longer. Further, the Cache may provide status and statistics to a data flow manager that determines which data to cache and which data to pipe directly through, or to switch cache policies dynamically, thus avoiding some of the cache overhead. The Cache may also place clean and dirty data in separate states to enable more efficient Cache mirroring and flush.
