  • Disk preservation and failure prevention in a raid array
    Patent number: 10360116
    Abstract: Methods, computer systems, and computer program products for configuring a redundant array of independent disks (RAID) array by a processor device, include, within a RAID array, configuring spare failover disks to run as cold spares, such that the cold spare disks stay in a powered-down standby mode, wherein each cold spare disk is powered on individually at predetermined intervals, tested, and powered back down to standby mode.
    Type: Grant

  • Magnetic tape rewind overwrite data protection
    Patent number: 9520145
    Abstract: A computer-implemented method for preventing overwriting of data, e.g., on a magnetic medium, includes receiving a write command to write to a magnetic tape. The current location of the magnetic tape is determined. A determination is also made as to whether data corresponding to the write command is at least one of: a size and type specified for a block at the current location. Execution of the write command is disallowed in response to determining that the data corresponding to the write command is not of the specified size and/or type.

  • Magnetic tape rewind overwrite data protection
    Patent number: 9153246
    Abstract: A method for preventing overwriting of data, e.g., on a magnetic medium, includes receiving a write command to write to a magnetic tape. A determination is made as to whether a current location of the magnetic tape is at a block at a beginning of tape. A determination is also made as to whether data corresponding to the write command is at least one of: a size and type specified for the block. Execution of the write command is disallowed when the data corresponding to the write command is not of the specified size and/or type.
