A complete revision of Clark's best-seller - Designing Storage Area Networks.
Provides guidelines for implementing SANs to solve existing networking problems in large-scale corporate networks.
Substantial additional material added since the best-selling first edition.
Tom Clark is Board Member Storage Networking Industry Association (SNIA) and Co-Chair of SNIA Interoperability Committee.
This is a fully updated revision of Designing Storage Area Networks. It collapses or removes dated material from the original edition and adds new content, particularly in the area of Fibre Channel fabrics, IP SANs and storage virtualization. Storage area networks are now recognized as the preferred solution for fulfilling a wide range of critical data storage needs for institutions and enterprises. The success of SANs in establishing real end-user value is affirmed by the adoption of the technology by all major solution providers as their flagship server and storage offerings. IBM, Hewlett-Packard, Sun, Dell and others now provide certified SAN configurations for performance, high availability and backup of storage data, while storage vendors such as EMC, Hitachi Data Systems, XIOtech and others offer SAN interfaces on their premier products. While the current market penetration of SAN-based solutions is only 20% of the total storage market, SANs are expected to capture the majority of the market within a few years. Tom Clark is Director of Technical Marketing at Nishan Systems, Inc. He is also a board member of the Storage Networking Industry Association (SNIA) and Co-Chair of the SNIA Interoperability Committee. Tom is extremely well known in storage circles and speaks regularly at conferences; as well as being involved with standard setting within the industry. Product Description

Backcover
Designing Storage Area Networks, Second Edition, succinctly captures the key technologies that are driving the storage networking industry. Tom Clark's works are helping to educate the IT community to the benefits and challenges of shared storage and are recommended reading for anyone wishing to understand this exciting new technology.
-Sheila Childs, VP Product Management, Legato Systems Chairperson, SNIA
Fibre Channel SANs have become a mainstay at the backend of the biggest corporations on the planet. The second edition of Designing Storage Area Networks brings the next wave of connection (IP) points and management into context, helping the user to quickly understand all the benefits before them.
-Steve Duplessie, Founder and Senior Analyst, Enterprise Storage Group
Designing Storage Area Networks, Second Edition, provides a practical roadmap through the ever-changing landscape of SAN technology. The new Fibre Channel, IP, and virtualization initiatives covered in this work will enable customers to implement comprehensive shared storage solutions that reduce management overhead and cost.
-John Webster, Founder and SeniorAnalyst, Data Mobility Group
Storage Area Networks (SANs) are now recognized as the preferred solution for fulfilling institutions' and enterprises' critical data-storage needs. Whether powered by Fibre Channel or TCP/IP and Gigabit Ethernet technology, SANs far exceed the capabilities of traditional storage access methods. SANs are quickly becoming the solution of choice for organizations that require high-volume data-handling capacity.
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.
Designing Storage Area Networks, Second 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.
