Abstract
In one embodiment, a method for managing information related to dirty data stored in an intermediate cache coupled to one or more clients and to an external memory includes receiving a dirty data notification related to dirty data residing in the intermediate cache, the dirty data notification including a memory address indicating a location in the external memory where the dirty data should be stored and a data type associated with the dirty data, and extracting a bank page number from the memory address that identifies a bank page within the external memory where the dirty data should be stored. The embodiment also includes incrementing a first count associated with a first entry in a notification sorter that is affirmatively associated with the bank page, determining that the dirty data has a first data type, and incrementing a second count associated with the first entry.
