USING CACHE LISTS FOR MULTIPLE PROCESSORS TO CACHE AND DEMOTE TRACKS IN A STORAGE SYSTEM

摘要

Provided are a computer program product, system, and method for using cache lists for multiple processors to cache and demote tracks in a storage system. Tracks in the storage stored in the cache are indicated in lists, wherein there is one list for each of a plurality of processors. Each of the processors processes the list for that processor to process the tracks in the cache indicated on the list. A determination is made of one of the lists from which to select one of the tracks in the cache indicated in the determined list to demote. The selected track is demoted from the cache.
