Publication number: 20130326135Abstract: An apparatus and associated methodology providing a data storage system including a memory having a first addressable storage space and a second differently addressable storage space. A controller selectively accesses stored instructions that when executed store a first amount of a user data set to the first addressable storage space and store a different second amount of the user data set to the second addressable storage space. The controller subsequently calculates an address increment between the stored first and second amounts, and then shifts one of the stored first and second amounts by the address increment.Type: ApplicationFiled: June 4, 2012Publication date: December 5, 2013Applicant: Spectra Logic CorporationInventors: Joshua Daniel Carter, Burkhard Eichberger, Matthew Thomas Starr

Patent number: 8457778Abstract: A robotic tape library which queues two or more move instructions is described. Generally, the robotic system receives a first move instruction which commands a first robot to move a first tape cartridge from a shelf to a first tape drive to be loaded therein. Though the first move has not actually taken place, the library replies to the host computer that the first tape drive has been loaded with the first tape cartridge, at least to an acceptable level of engagement, at which point, the first move instruction is queued. After receiving a second move instruction from the host to move a second tape cartridge from the shelf to a second tape drive, the library reorganizes and physically carries out the move instructions in a preferred order.Type: GrantFiled: August 15, 2008Date of Patent: June 4, 2013Assignee: Spectra Logic Corp.Inventors: Matthew Thomas Starr, Michael Gerard Goberis

Patent number: 8453010Abstract: A method for recovering data from a failed tape cartridge is presented. The reliability of a tape cartridge is assessed via the number of read errors encountered. If the number or read errors is excessive, the tape cartridge is deemed unreliable and the tape cartridge is restricted from storing anymore data. A search is performed to look for duplicate data and if found a copy of the duplicate data is stored to a replacement tape cartridge. The replacement tape cartridge assumes all identity of the original failed tape cartridge.Type: GrantFiled: July 11, 2012Date of Patent: May 28, 2013Assignee: Spectra Logic Corp.Inventors: Nathan Christopher Thompson, Matthew Thomas Starr, Walter Wong
