Thank you for all the feedback. Even though we are all virtual tape, I am under the impression that not all the data residing on tape should be. Yes it's virtual and therefore disk, but many of the JCL used today is old and since there is no chargeback for tape, users continue to write their data to tape. I am looking into this to help determine where the data should reside. The best will probably be looking at smaller tapes and having those go to disk instead. I'm thinking starting with 50 MB.
