Workspace IBM TS7700 Virtual Tape Library

RELATED IDEAS

Increase logical tape drives per cluster to more than 496

TS7700s get more robust with each generation released allowing for more systems to share the high-bandwidth I/O and storage capacity but the logical tape drives have not increased, making it difficult to assign sufficient tape units to each sharing z/OS sysplex. I believe the limitation exists with a total number assigned to a composite library but it shouldn't be assumed each of 8 clusters would be online to a specific host. Customers many need many more logical tape drives assigned from one or more clusters but not from other clusters, never exceeding the total for the composite library by z/OS system. Maybe 2048 per cluster should be permitted.

    This will need to be investigated with zOS team due to host implications
