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 authorabout the technology in general, how it works, what it does, and what it can't do.
Storage virtualization is a new field that has considerable interest for information technology managers. There is currently no single work that provides an objective, technical explanation of virtualization technologies. This book examines new storage virtualization technologies that automate data storage processes, including data placement, replication, and back-up. Storage virtualization is designed to ease storage management by presenting your storage network's physical assets in a logical form. Making storage networks easier to manage can save a company money and make a storage network more efficient. Storage Virtualization provides a technical overview of how virtualization applications work and also includes practical case examples from the real world. Topics covered include: virtualizing at the host level, fabricbased virtualization, virtualization appliances, virtualized file systems, virtualization engines, and virtualized tape back-up.

Backcover
Tom Clark gives us a clear, readable guide to this emerging technology. He explains how it works, what problems it solves, and where it fits in an evolving IT infrastructure.
-Milan Merhar
Tom Clark gives us a strong overview of contemporary storage technology with storage virtualization as the central theme-a valuable work for all those seeking a broad understanding of storage in an IT infrastructure.
-David Thiel, HP Fellow and Chair of the SNIA Technical Council
Storage virtualization technology holds immense promise for streamlining data storage operations and making the unmanageable manageable. In this work, Tom Clark provides a comprehensive overview of virtualization concepts and the practical benefits customers can realize. Storage Virtualization is recommended reading for anyone wanting to understand this next wave of innovative networked storage technology.

Evaluating, Planning, and Implementing High-Value Storage Virtualization Solutions
Storage virtualization has come of age, offering IT professionals powerful new ways to simplify infrastructure, streamline management, improve utilization, and reduce costs. Now, the author of the best-selling storage books IP SANs and Designing Storage Area Networks presents an up-to-the-minute, vendor-neutral overview of storage virtualization in all its forms.
Writing for IT managers, administrators, architects, analysts, consultants, and vendors, Tom Clark explains everything from the basics to the latest emerging standards. Storage Virtualization uses realistic examples and diagrams to explain each key concept, concluding with case studies that demonstrate real-world implementation and help you assess the technology's business value. Coverage includes
The current state of both storage virtualization technologies and the marketplace
Relationships among files, records, data on disk, and storage interconnections
Virtualization standards, including the Fabric Application Interface Standard
How multiple storage systems are abstracted into virtual storage pools
Host-based virtualization, array-based virtualization, and virtualization appliances
Virtualization services for high availability and heterogeneous storage applications
Virtualized SAN file systems that simplify file management and support distributed computing
Virtualized tape backup, including Redundant Array of Independent Tape (RAIT) devices
Policy-based storage management, application-sensitive virtualization intelligence, and other high-level automation and virtualization services
The future of storage virtualization and storage utilities
Extensive resource listings: vendors, industry organizations, and standards initiatives
