You can read some more at: http://ca.com/us/products/product.aspx?id=1599 http://ca.com/files/ProductBriefs/ca_vtape_virtual_tape_system_pb.pdf The Virtual Tape system intercepts requests for scratch mounts, buffers them on disk as Virtual Volumes then stacks the Virtual Volumes onto a physical tape, fully utilizing it.
It was regularly brought to our attention by CA, but we have good control over our production JCL and tape allocations and were able to redirect the production tape allocations to disk ourselves when needed. If your IT department does not have control over production JCL, then this product is valuable to redirect tape allocations to disk from a central, systems point of control. Kees.
