摘要： Storage system(s) for storing data in physical storage in a recurring manner, method(s) of operating thereof, and corresponding computer program product(s). For example, a possible method can include: upon start of a storage recurrence, destaging dirty data which had been accommodated in the cache memory prior to the start of said storage recurrence thus giving rise to destaged data group, wherein destaging is provided with no overwriting of at least superseded data destaged before starting said storage recurrence while enabling retaining metadata indicative of location of said superseded data in the physical storage space; accommodating data obtained in said cache memory subsequent to the start of said storage recurrence while preventing said data from being destaged during said storage recurrence, thus giving rise to accommodated data group; and registering a point-in-time indicative of successful destaging of the destaged data group, thereby providing an order-preservation consistency indication corresponding to said recurrence.

摘要： There are provided a mass storage system comprising a control layer operatively coupled to a physical storage space and operable to interface with one or more clients and to present to said clients a plurality of logical volumes. The method of operating the storage system comprises: dividing one or more logical volumes into a plurality of statistical segments with predefined size; assigning to each given statistical segment a corresponding activity level characterizing statistics of I/O activity with regard to data portions within the given statistical segment, said statistics collected over a plurality of cycles of fixed counting length; and managing one or more data storage processes in the storage system (e.g. a background defragmentation process, a background garbage collection process, a destage management process, etc.) using said activity level.

摘要： A control layer of a data storage system is configured to identify one or more physical data units in the physical storage, which are associated only with corresponding logical snapshot data units, and to reallocate such physical snapshot data units to a dedicated storage space. The dedicated storage space can be a low-power storage space, which includes one or more disks designated as low power disks. The reallocation of snapshot data units to low power disks can be carried out according to an energy-aware migration policy, directed for minimizing the activation of the low power disks, and maintaining the disks in an inactive state for longer periods of time.

摘要： A method for hot backward compatible upgrade of a storage system includes: a) configuring each virtual partition (VP) to be controlled by a primary data server and a secondary data server b) configuring each data server to have primary responsibility over all logical block addresses (LBAs) corresponding to at least two virtual partitions and to have secondary responsibility over all LBAs corresponding to at least two other virtual partitions; c) responsive to a shut-down of a data server, i) re-configuring primary responsibility over each VP previously primary controlled by the shut-down server such that it becomes primary controlled by a server previously configured as a secondary server with respect to this VP; ii) re-allocating secondary responsibility over each VP previously secondary controlled by the shut-down server in a manner that each such VP becomes secondary controlled by a server other than the newly assigned server with primary responsibility.
