This IBM® Redbooks® publication introduces the IBM System Storage® TS7680 ProtecTIER® Deduplication Gateway for System z® (3958-DE2) hardware and the IBM System Storage ProtecTIER Deduplication Gateway for System z V1.1 software. These are designed to help address the tape processing needs of System z data centers by improving the data protection infrastructure and more cost effectively managing and protecting critical client data.

Managing this growth has become the primary source of pain for storage professionals, who are grappling with the following challenges:

- Growing storage acquisition and management costs

- Data processing administration

- Shrinking batch windows

-Demanding service levels

The TS7680 helps alleviate these challenges.
