Abstract: A method for more efficiently utilizing data compression in block-level storage systems is disclosed. In one embodiment, such a method includes receiving, by a storage system, I/O operations from a host system. The storage system determines, at a selected interval, a compression rate of data associated with the I/O operations. Using the compression rate determined at the selected interval, the storage system updates an average compression rate. The storage system then determines whether the average compression rate is above a threshold. If the average compression rate is above the threshold, the storage system compresses data associated with I/O operations from the host system. If the average compression rate is not above the threshold, the storage system does not compress data associated with I/O operations from the host system. A corresponding system and computer program product are also disclosed.

Abstract: A method for recovering modified data lost from cache includes maintaining, in a cache of a primary storage system, a destage data structure indicating which modified data in the cache has been destaged. The method further maintains, in cache of a secondary storage system, a change recording data structure indicating which modified data has been replicated from the primary storage system to the secondary storage system. The method further merges the destage data structure with the change recording data structure to yield an updated change recording data structure. In the event modified data in the cache of the primary storage system is lost, the method utilizes the updated change recording data structure to determine which modified data in the secondary storage system is needed to restore the modified data lost from cache at the primary storage system. A corresponding system and computer program product are also disclosed.
