Abstract: A system and method for global data de-duplication in a cloud storage environment utilizing a plurality of data centers is provided. Each cloud storage gateway appliance divides a data stream into a plurality of data objects and generates a content-based hash value as a key for each data object. An IMMUTABLE PUT operation is utilized to store the data object at the associated key within the cloud.

Abstract: Technology is described for a profile-based lifecycle management for data storage servers. The technology can receive a profile, monitor events emitted by devices of the data storage system, determine based on the monitored events that a device of the storage system matches the indicated condition, and perform the action corresponding to the indicated condition, wherein the action includes managing data stored by the data storage system. The received profile can indicate a condition and an action corresponding to the condition.

Abstract: Systems and methods which provide for improved prefetching schemes for caching data in a storage network are described. In one embodiment, a dynamically adaptive prefetching mechanism based on block access history information and prior effectiveness of prefetching is provided. Embodiments may take into account prefetch efficiency; a dynamic value indicating the usefulness of past prefetches, prefetch wastage, in conjunction with prefetch resources available at any point in time, to determine the number of blocks to read-ahead during a prefetch. Such embodiments provide improvements over file-based prefetching and previous block schemes, as they provide a finer grain of control over both prefetch block selection, and the number of blocks to prefetch based on block (or block range) access history.
