    Abstract: Aspects for handling destage requests during shutdown in a log-structured array storage subsystem are described. In a method aspect, the method includes receiving a shut-down command, and utilizing at least three data structures for tracking destage requests when the shut-down command is received, wherein closing of open segments before completion of the shut-down is ensured. A further method aspect includes maintaining an outstanding requests list and destage requests list, forming a missing requests list based on the contents of the outstanding requests list and destage requests list when a shut-down command occurs, and tracking destage request processing with the outstanding requests list, destage requests list and missing requests list until all destage requests have been successfully completed.

    Abstract: In a storage system comprising an array of storage devices, including a processor and memory, a plurality of logical tracks are organized on the storage devices in segments comprising columns striped across the storage devices. A system and method are provided for storing logical tracks in the storage devices. Sequentially logically related logical tracks are stored together in neighborhoods. Logical tracks of the same neighborhood destaged at the same time are assigned to a single open segment with other logical tracks of the same neighborhood type. The time at which open segments are designated as closed segments to be written to the storage devices is based on performance, disk utilization and memory utilization criteria. Logical tracks are never split between segment columns. Also, attempts are made not to split a neighborhood of logical tracks being destaged together between segment columns.

    Abstract: In a storage system comprising an array of storage devices including a processor and memory, a plurality of data blocks are organized on the storage devices in segments striped across the storage devices. A main directory, stored in memory, contains the location on the storage device of each of the data blocks. For each segment a segment directory having information on the data blocks in the segment is stored on the storage devices. When a damaged segment directory is detected, a checkpoint of the main directory is written to the storage devices. A list is maintained of damaged segment directories such that segments on the damaged segment directories list are not garbage collected. Following a main directory recovery procedure, the damaged segment directories are reconstructed using the main directory.
