Abstract: Systems and methods for improving caching mechanisms in a storage system are disclosed. The method includes storing data associated with a write input/output (I/O) request at a cache; determining an amount of dirty data stored in the cache, where the dirty data is data in the cache that has not yet been written to a persistent storage location managed by a storage system; determining if the amount of dirty data exceeds a threshold value; determining a cache flush rate based on the amount of dirty data stored at the cache, when the amount of dirty data exceeds the threshold value; and writing data from the cache at the determined cache flush rate to the persistent storage location.
