Abstract:
A storage tier management application indicates a heat index for each extent of a plurality of extents, wherein a higher heat index indicates a greater frequency of usage of tracks of an extent than a lower heat index. A least recently used (LRU) list for cache management is configured to perform demotion of tracks of a lower heat index prior to demotion of tracks of a higher heat index.

Claim (Index 27):
A computer program product, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations, the operations comprising:\n maintaining a list comprising a plurality of partitions, wherein each partition of the plurality of partitions is comprised of a plurality of tracks, and wherein each partition of the plurality of partitions represents a heat index range; adding, by a cache management application, a new track to the list by:\n determining a heat index of the new track as indicated by a storage tier management application; and \n including the new track in a partition of the plurality of partitions whose heat index range encompasses the heat index of the new track; and \n demoting, by the cache management application, a track from the list by:\n determining which partition of the plurality of partitions has a heat index range that encompasses lowest heat indexes; \n determining whether the determined partition has one or more tracks; \n in response to determining that the determined partition has one or more tracks, demoting a least recently used (LRU) track of the determined partition; and \n in response to determining that the determined partition does not have one or more tracks, determining a new partition of the plurality of partitions that has a heat index range that encompasses next lowest heat indexes for demoting one or more additional tracks from the list.
