Introduction - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

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.
