ABSTRACT:
A cache management system and method monitors and controls the contents of cache memory. A time indication provider provides a time indication signal to a cache indexer, for maintaining a cache index which are stored in cache as well as an indication that a data element must be written to a longer term data storage device. A cache manager is responsible for placing data elements into and removing data elements from the cache memory. The cache manager is responsive to at least one data element stored in cache which must be written to a longer term data storage device, and to the associated time indication, for determining the amount of time that the data element has been stored in cache as well as the average period of time that elapses between a data element being inserted in cache and being removed from cache. Based on a comparison of the average period of time that elapses between a data element being entered into and removed from cache and the amount of time that the data element which is written to a longer term data storage device has been stored in cache, the cache manager determines whether to place the data element in the top of the cache, to allow the data element to remain in cache a longer period of time, or at the bottom of the cache which will cause the date element to be removed from cache more quickly.
