  • Publication number: 20240143221
    Abstract: A computer implemented method includes executing a read-ahead operation by reading data from a tape according to a read plan and storing said data in a ring buffer, determining whether the ring buffer is full, receiving a command indicating an area to be read according to the read plan, and, responsive to receiving the command, reading data from an area of the list of areas to be read corresponding to the command from the ring buffer. The method may further include executing additional read-ahead operations until the ring buffer is full. A computer program product and computer system corresponding to the method are also disclosed.

  • Patent number: 11954353
    Abstract: In an approach to improve magnetic tape file systems through tape-to-tape copying between nodes on a Linear Tape File System using a cluster-wide named pipe. Embodiments transfer data between a first node and a second node. Additionally, both the first node and the second node implement a parallel shared-disk file system through a data path for node data reading and writing from a shared-disk and to the shared-disk. Further, to transfer data between the first node and the second node, embodiments, write, by the first node, the data for tape-to-tape copy from a first tape drive to the shared-disk, and write, by the second node, the data written from the shared-disk to a second tape drive.

  • Publication number: 20240094949
    Abstract: A computer implemented method includes receiving a list of areas on a subject tape to be read, wherein each area of the list of areas is indicated by a first record number and a last record number corresponding to the area, identifying parameters of a tape drive configured to read the subject tape, wherein the identified parameters of the tape drive contribute to a speed with which the tape drive can read the list of areas, creating a directed graph of the areas on the subject tape based on the identified parameters, wherein the directed graph indicates how long the tape drive will take to read the areas on the subject tape, and determining a fastest reading order of the areas on the subject tape, based, at least in part, on the directed graph and the identified parameters. A computer program product and computer system are also disclosed.

  • Patent number: 11934699
    Abstract: A computer-implemented method for unoptimized tape drive read detection is disclosed. The computer-implemented includes determining whether a read order of a trio of related files is consistent with an order in which the trio of related files are stored on a magnetic tape media. The computer-implemented method further includes generating an unoptimized tape drive read warning in response to determining that the read order of the trio of related files is inconsistent with the order in which the trio of related files are stored on the magnetic tape media.
