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.

There is a product from CA, also called VTAPE, which runs on z/OS. It
emulates tape on z/OS DASD. We got rid of it due to high CPU
utilization. We never tried to determine if it was the product or the
way we customized it.
