  • 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.
