Designing storage area networks (2^nd Ed.) A Practical Reference for Implementing Fibre Channel and IP SANs

Written for network developers, IT consultants, administrators, and managers, this updated and greatly expanded edition of the best-selling Designing Storage Area Networks goes far beyond a straight description of technical specifications and standards. The text offers practical guidelines for using diverse SAN technologies to solve existing networking problems in large-scale corporate networks. With this book you will learn how the technologies work and how to organize their components into an effective, scalable design. In doing so, you will discover today's best methods for managing storage area networks, including new troubleshooting techniques. This new edition, also features detailed case studies that demonstrate how SANs can solve a number of commonly encountered business challenges, including LAN-free and server-free tape backup, server clustering, and disaster recovery. As an information-systems professional, you must keep pace with this powerful, evolving technology.
