A system for managing data in a plurality of storage locations. In
response to a least recently used algorithm wanting to move data from a
cache to a storage location, an aging table is searched for an associated
entry for the data. In response to finding the associated entry for the
data in the aging table, an indicator is enabled on the data. In response
to determining that the indicator is enabled on the data, the data is
kept in the cache despite the least recently used algorithm wanting to
move the data to the storage location.
