Writing a technical book is very much like building a house. It springs from inspiration, necessity, aesthetics, multiple talents, and hard work. Nothing would get published if the myriad of small tasks were not completed to meet deadlines from a project plan. My appreciation goes to all of those talented people who worked and contributed to this book.

If there is any dedication of this book it is to Donn Thornton for his inspiration. Donn was instrumental in teaching me the value of understanding, listening, and more importantly thinking, not only outside the box, but outside the universe. This book moved forward with the help of Kevin Ansell, whose experiences and discussions helped me through many difficult times. My thanks and appreciation goes out to Kevin for his sense of humor and encouragement.

Franny Kelly, acquisition editor at McGraw-Hill/Osborne, championed keeping this project alive and on schedule. My thanks to Franny for trusting me with the completion of this large project. Regarding the tremendous task of assembling all the writing into a real-live book, Id like to convey my sincere thanks to my project editor, Jody McKenzie. Jody (along with her talented copyeditors) was critical to my technical dissertations becoming a coherent set of text and artwork and, subsequently, a completed manuscript.

I admit it; technically, I had help. Patty Then, storage consultant extraordinaire proved a much-needed sounding board in the review and validation of a wide set of technical concepts and specifications that make up this book. Pattys knowledge of systems, storage infrastructures, and data centers was a key resource in illustrating the technical aspects of the SAN. She is one of those rare individuals versed in performance, capacity planning, and operational experiences that span both mainframe and open systems. I also need to thank Himanshu Dwivedi for his work in Chapter 25 on the increasing interests and concerns regarding security in storage infrastructures .

My thanks and appreciation also go to Ian Spalding, technical and creative writer, for his last-minute assistance in writing some of the key chapters from my encrypted notes. In addition, Ian was enlisted again to assist in proofing the book before final publication. We all wish you the best of success on your first novel .

Finally, all of this work would not have been possible without the support, assistance, inspiration, and help from my partner and wife, Artie. Her help in moving this book toward completion was more than anyone could ask. Thank you.
