  • Write efficiency management for tape cartridge writing
    Patent number: 11410687
    Abstract: One or more write efficiency metrics are determined. The one or more write efficiency metrics are associated with a tape storage drive while the tape storage drive is operating on one or more tape storage media cartridges to write data sets to the one or more tape storage media cartridges. It is predicted whether the tape storage drive would be able to write an entire set of data sets to a current tape storage media cartridge based on the one or more write efficiency metrics. It is determined whether a different tape storage drive is to be utilized to complete writing of the entire set of data sets to the current tape storage media cartridge based on the prediction.

  • Efficient data recovery for tape storage system
    Patent number: 11237736
    Abstract: An indication that a selected data set stored on a selected tape storage media is associated with a failure is received. An error correction data set group for the selected data set is identified, and wherein the error correction data set group includes a plurality of data sets and each data set included in the error correction data set group is stored on a different tape storage media. One or more data sets other than the selected data set that are included in the error correction data set group are selectively obtained from one or more corresponding tape storage media other than the selected tap storage media without reading entire contents of the one or more corresponding tape storage media. The obtained one or more data sets are utilized to recover at least a portion of the selected data set associated with the failure.
