GFS/Stack eliminates resource waste in z/OS tape libraries by promoting real savings with surprising simplicity and results. It allows full usage of any volume capacity in execution time, quickly releasing thousands of tapes.

Besides enabling the use of multi-file/multi-volume features, GFS/Stack provides significant reduction in the number of tape mounts, thus optimizing the production performance and considerably reducing the elapsed time for jobs that use tapes.
