1 Introduction Welcome to virtual tape libraries. This guide describes the HP StorageWorks VLS and D2D systems and their concepts, including automigration, deduplication, and replication, to help you define and implement your virtual tape library system. It includes best practices for working with specific backup applications. Although every user environment and every user's goals are different, there are basic considerations that can help you use the VLS or D2D effectively in your environment. The VLS and D2D are two powerful and flexible families of devices. Because they can be productively used in so many ways, there is no "best" configuration. But by asking yourself the questions and following the parameters outlined in this guide, you can define and implement a system that is best for your particular environment and applications. Before proceeding, make sure you are familiar with the items below. • Tape backup technologies, tape libraries, and backup software. • SAN environments. • Fibre Channel technology. See the Glossary for the definition of acronyms and specific terms. NOTE: This guide replaces the HP StorageWorks Virtual Library System Solutions Guide, the HP StorageWorks Deduplication and replication solutions guide, and the HP StorageWorks Deduplication solutions guide.
