Patent number: 11954353Abstract: 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.Type: GrantFiled: September 24, 2021Date of Patent: April 9, 2024Assignee: International Business Machines CorporationInventors: Atsushi Abe, Tohru Hasegawa, Hiroshi Itagaki, Tsuyoshi Miyamura, Shinsuke Mitsuma, Noriko Yamamoto
