ABSTRACT:
A cache management system and method monitors and controls the contents of cache memory coupled to at least one longer term data storage device. Cache memory is organized into at least first and second sections, the first section for storing data waiting to be written to a longer term data storage device and the second section for storing data elements which have been written to the longer term data storage device. The cache management system and method monitors data elements awaiting writing to the longer term data storage device. Once the elements have been actually written to the longer term data storage device, the cache management system and method utilizes an indication of the amount of time the data element was in cache as well as an indication of the number of times the data element was accessed, in order to determine how long to maintain the data record in the short term cache
