Storage virtualization is a new field that has considerable interest forinformation 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 moreefficient. 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, fabricbasedvirtualization, virtualization appliances, virtualized file systems,virtualization engines, and virtualized tape back-up.
Tom Clark has held technical director positions at McDATA Corporation and other storage networking companies, conducts SAN seminars and tutorials worldwide, and serves as customer liaison. A noted storage industry author and advocate, he is a former board member of the Storage Networking Industry Association (SNIA) and has held chair positions for SNIA customer initiatives and the SNIA Interoperability Committee. His previous Addison-Wesley books include Designing Storage Area Networks, Second Edition (ISBN 0-321-13650-0) and IP SANs: A Guide to iSCSI, iFCP, and FCIP Protocols for Storage Area Networks (ISBN 0-201-75277-8). © Copyright Pearson Education.
