Abstract
Write caching for sequential tracks is performed by a processor device in a computing storage environment for destaging data from nonvolatile storage (NVS) to a storage unit. If a first track is determined to be sequential, and an earlier track is also determined to be sequential, a temporal bit associated with the earlier track is cleared to allow for destage of data of the earlier track. If a temporal bit for one of a plurality of additional tracks in one of a plurality of strides in a modified cache is determined to be not set, a stride associated with the one of the plurality of additional tracks is selected for a destage operation. If the NVS exceeds a predetermined storage threshold, a predetermined one of the plurality of strides is selected for the destage operation.
