    摘要: A method to store data is disclosed. The method provides a plurality of data storage media, an automated data library comprising one or more data storage devices, a first plurality of storage cells, and a robotic accessor. The method further provides a storage vault comprising a second plurality of storage cells but no data storage devices. The method selects the (i)th data storage medium and sets the (i)th data state, where that (i)th data state is selected from the group consisting of online, offline, and vault. If the method sets the (i)th data state is set to online, then the method mounts that (i)th data storage medium in one of the data storage devices. If the method sets the (i)th data state to offline, then the method removeably places the (i)th data storage medium in one of the first plurality of storage cells. If the method sets the (i)th data state is set to vault, then the method places the (i)th data storage medium in one of the second plurality of storage cells.

    摘要: The invention relates virtual tape systems. A method of controlling a cache controller is disclosed comprising the steps: a) when writing current application data to a logical volume resident in said random-access cache; b) maintaining surrounding cache storage location meta information—in most cases block addresses—about application data which was also written to the cache within a predetermined time surrounding of the current data, which is understood as adaptive read caching; c) when reading (recalling) the current data from tape into the cache in response to an application request; d) also reading respective surrounding application data according to the current data time surrounding from tape to cache in order to anticipate further reads to be performed later by the application.

    摘要: A system, method and computer program product for managing command ordering and command execution for a host-Disk-to-intermediate-Disk-to-Holographic (D2D2H) data storage system. Specifically, a command ordering and execution (COE) utility selects the command group from a command queue. A determination is made whether the command group includes a write command for writing an entire hologram segment. Responsive to a determination that the command group does not include the write command for writing the entire hologram segment, the entire hologram segment is read to an intermediate system disk. Conflicting commands are then sorted from non-conflicting commands. Specifically, all conflicting write commands are executed before all conflicting read commands. After execution, the entire hologram segment of the intermediate system disk is closed and written in holographic medium.

    摘要: A system, method and computer program product for managing command ordering for a host-Disk-to-intermediate-Disk-to-Holographic (D2D2H) data storage system. Specifically, a command ordering detects a command from a host system. A hologram segment associated with the detected command is identified and a determination is made whether the hologram segment is an open hologram segment or a closed hologram segment. A determination is made whether the detected command is to be prioritized. If the detected command is prioritized, the detected command is added to a prioritized command queue. Moreover, if the detected command is not prioritized, the detected command is added to a normal command queue. The detected commands addressing the same hologram segment are then grouped. The execution of one or more grouped commands (prioritized or normal) is deferred for a predetermined period to allow for additional commands to be received for a same command group.

    摘要: A method of adaptively selecting an optimum data deduplication chunking method receives a request to deduplicate a file, wherein the file has a file type. The method searches a table of file types, wherein the table includes, for each file type, a chunking method, a deduplication ratio, and a depulication ratio threshold. The method selects a chunking method for the file according to the table. The method chunks the file using the selected chunking method. The method deduplicates the chunked file according to prior art deduplication methods. The method calculates a deduplication ratio for the file type and updates the table with the calculated deduplication ratio for the file type. If the calculated deduplication ratio for the file type is less than the deduplication ratio threshold for the file type, the method selects a new chunking method for the file type and updates the table of file types with the new chunking method for the file type.
