Storage Virtualization: Technologies for Simplifying Data Storage and Management

Storage virtualization is a new field that has considerable interest for information technology managers. There is currently no single work thatprovides an objective, technical explanation of virtualization technologies.This book examines new storage virtualization technologies that automate datastorage processes, including data placement, replication and back-up. Storagevirtualization is designed to ease storage management by presenting yourstorage network's physical assets in a logical form. Making storage networkseasier to manage can save a company money and make a storage network more efficient. Storage Virtualization provides a technical overview of howvirtualization applications work and also includes practical case examples fromthe real world. Topics covered include: virtualizing at the host level, fabric basedvirtualization, virtualization appliances, virtualized file systems,virtualization engines and virtualized tape back-up.Features First Look: New storage virtualization technologies making storage devices easier and more cost-efficient to manage.° Standards are just emerging in this area and so, readers are looking for a book which will guide their implementation decisions.° All major storage vendors are embracing virtualization: EMC, Veritas, IBM, Sun, HP, Cisco.° A vendor-neutral, technology-neutral book by a brand name storage author--about the technology in general, how it works, what it does and what it can't do.Table of Contents Preface.Acknowledgments.1.
