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.

摘要： A method for performing write calibrations on holographic storage media is disclosed. Initially, five identical and known calibration holograms are written on a holographic storage medium, in which three of the five calibration holograms are written with different laser power and three of the five calibration holograms are written with different time durations. A matched filter is then utilized to determine a cross-correlation between the five calibration holograms read from the holographic storage medium and their corresponding ideal calibration holograms previously stored within a memory device within the holographic storage drive. A least-squares fit of an ellipsoidal parabola to the cross-correlations is subsequently calculated to yield an optimal laser write power level and an optimal duration for a laser write pulse.

摘要： A test system is described for testing a media drive, such as a tape drive. The test system includes a host emulator, a storage library emulator, and a control system. The host emulator communicates with a first interface of the media drive and mimics a host system to the media drive. The storage library emulator communicates with a second interface of the media drive and mimics a storage library system to the media drive. When in operation, one of the host emulator and the storage library emulator transmits a test message to the media drive responsive to an instruction from the control system. Responsive to the test message, one of the emulators receives a test response from the media drive and transmits the test response to the control system. The control system processes the test message and the test response to evaluate the performance of the media drive.
