Abstract
Destage grouping of tracks is restricted to a bottom portion of a least recently used (LRU) list without grouping the tracks at a most recently used end of the LRU list to avoid the destaging conflicts. The destage grouping of tracks is destaged from the bottom portion of the LRU list.
Claims21
A method for minimizing destaging conflicts by a processor device in a computing environment, the method comprising:
- restricting destage grouping of tracks to a bottom portion of a least recently used (LRU) list without grouping the tracks at a most recently used end of the LRU list to avoid the destaging conflicts;
- and
- destaging the destage grouping of tracks from the bottom portion of the LRU list.
A system for minimizing destaging conflicts in a computing environment, the system comprising:
- at least one processor device operable in the computing environment, wherein processor device:
- restricts destage grouping of tracks to a bottom portion of a least recently used (LRU) list without grouping the tracks at a most recently used end of the LRU list to avoid the destaging conflicts, and
- destages the destage grouping of tracks from the bottom portion of the LRU list.
A computer program product for minimizing destaging conflicts in a computing environment by at least one processor device, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
- a first executable portion that restricts destage grouping of tracks to a bottom portion of a least recently used (LRU) list without grouping the tracks at a most recently used end of the LRU list to avoid the destaging conflicts;
- and
- a second executable portion that destages the destage grouping of tracks from the bottom portion of the LRU list.
