Abstract: A computer program product is provided for efficiently managing storage in a multi-tiered storage system. The computer program product comprises a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a processor to cause the processor to receive a command from an application, where the command is directed to at least one object. The program instructions are further executable by the processor to cause the processor to determine storage for the at least one object in a multi-tiered storage system based on the command, and store the at least one object in accordance with the determined storage.

Abstract: The invention relates to a storage system comprising one or more storage controllers, two or more storage devices and two or more storage clients, the storage controllers, the storage devices and the storage clients being coupled via a network in order to exchange information between the storage controllers, said storage devices and said storage clients, wherein each storage client is adapted to provide data-path-storage commands to the storage devices via the network bypassing the storage controllers, wherein the storage system is adapted to provide data redundancy using a data redundancy scheme higher than RAID 1.

Abstract: An object-based data storage system includes a memory and a processor for executing machine executable instructions configured for implementing logical containers for data objects each having a global identifier. The containers are configured for storing metadata including a first parameterization value descriptive of a number of storage nodes and a second parameterization value descriptive of a classification of the data objects. The machine executable instructions are further configured for implementing a first object storage ring for addressing storage locations across the multiple storage nodes using a surjective function.

Abstract: A system according to one embodiment includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to store hierarchically-organized global configuration information for each node and each tape library resource in a storage cluster to at least one memory accessible by each node of the storage cluster. The storage cluster includes at least one tape library. Also, the logic is configured to cause the processor to migrate data to and/or recall data from a tape cartridge pool within a tape library, using the hierarchically-organized global configuration information and via a node which has access to the tape cartridge pool, in response to receiving a migration and/or recall request at any node of the storage cluster. Other systems, methods, and computer program products for management of data and resources in a tiered data storage system are described in more embodiments.

Abstract: A method, a secure device and a computer program product for securely managing files. The method includes providing a secure device, where the secure device is protected by design against malicious software or malware and adapted to establish a connection to a server via a host, the host connected to the server through a telecommunication network, upon receiving a request for using a file stored on the secure device, processing the request at the secure device according to an updated use permission associated to the file, where the updated use permission is obtained by instructing at the secure device to establish a connection between the secure device and the server via the host and updating at the device the use permission associated to the file, according to permission data sent from the server through the established connection.

Abstract: In a general embodiment, a method includes storing hierarchically-organized global configuration information for each node and each tape library resource in a storage cluster to at least one memory accessible by each node of the storage cluster, the storage cluster comprising at least one tape library. The method further includes migrating and/or recalling, using the hierarchically-organized global configuration information, data to and/or from a tape cartridge pool within a tape library. The migration or recall is performed by an appropriate node of the storage cluster and in response to receiving a migration or recall request at an arbitrary node of the storage cluster.

Abstract: A method for managing a memory is disclosed, the memory including a set of units and a unit comprising a set of pages, wherein a unit of the set of units is erasable as a whole by a unit reclaiming process resulting in a free unit available for writing data to. The method includes maintaining a first pool of units available for reclamation by the unit reclaiming process; maintaining a second pool of units not available for reclamation by the unit reclaiming process; moving a first unit from the first pool to the second pool in response to invalidating a first one of the pages contained in the first unit; returning the first unit from the second pool to the first pool after a defined number of units of the set have been written; and selecting a unit out of the first pool for reclamation by the unit reclaiming process.
