Summary: Good introduction
Review: Hi,This books serves as good introduction to SAN and NAS. It covers backup and recovery for SANs very nicely and at appropriate level. As far as NAS is concerned, it skims the topic. Its a good introduction to various technologies. The details will have to found elsewhere. Overall review - worth reading it.

Summary: A balanced book on NAS and SAN
Review: I found this to be an excellent introductory book on SAN and NAS. The book is divided equally between the two technologies. I certainly recommend it for any one who wants to get into network storage technology.

Summary: Very Good treatment of the subject
Review: If you are looking for a very concise examination of SAN and NAS technologies, this is the right book. While it is a fraction of the size of some other books on the topic, it is a to-the-point treatment of the major architectural components of each.
There is a lot of foundation info that is somewhat assumed and reviewed briefly, but the killer chapters are on backup and restore methodologies around these technologies.
This is not a disk array or fibre-channel switch product guide nor does it explain every last detail of SCSI commands. But if the need is to understand these technologies and their place in your infrastructure, this is a good work.
Well worth the purchase price.

Summary: For IT Architects and Storage Administrators
Review: If you are looking for an overview of SAN and NAS that is both technically informative and equitable, this is the book for you. I bought it to better understand NAS-SAN convergence trends and it was invaluable for that purpose. As with most O'Reilly books, it doesn't underestimate the reader, yet still manages to cover all the bases from basic to bread-and-butter, and beyond. The prose style is casual but very precise and always clear. I want to stress what an earlier reviewer pointed out: it is especially strong on real world backup and restore issues...which is MUCH more important and complex than is initially apparent. If you are tasked with building a real-world storage infrastructure: read this book first. BTW, because my local B&N was out-of-stock, I paid extra to have [Amazon.com] expedite this slim volume, (grumbling all the way), and ended up happy as a clam about it. Best IT book investment I ever made.

Summary: Good Overview
Review: This book has a good 10K foot overview and basic groundings for beginners. Also is good at comparing and contrasting SAN vs NAS. But, very light on detail especially in the area of NAS. If you don't know anything about SAN/NAS give it a read. If you've much experience it'll be mostly review.

Summary: Good introduction
Review: This book is really good at bringing together a lot of different details together having it make sense. It has been a couple of years since I worked on SANs and reading this book really refreshed the concepts for me. W. Curtis Preston's writing style is very easy to follow as he usually adds in insightful side items to break up the book a bit. I was expecting a very well written book as I also read his backup & recovery book which I really enjoyed too. I reccomend this book to anyone who is starting to investigate san or nas solutions or wants to get a good solid starting point with those technologies.

Summary: Lacks organization, not authoritative
Review: This book provides a high-level overview of SANs and NAS, with occasional and innapropriate plunges into technical detail. It is not suitable as a technical reference; it is somewhat useful as an introduction to these two topics. Sadly, the title is below the quality level of most O'Rreilly books: * Many important topics are covered in multiple chapters, making the book hard to use as a reference, e.g., LUN Masking and zoning.
* The quality of the writing is poor. It is also overly colloquial, e.g., when introducing his own term, client-free backups, Preston writes, "That's my story and I'm sticking to it."
* There is no glossary; the index is very poorly done.

Summary: Good terminology book
Review: This book very well covers its objective of orienting one with SAN and NAS market and its major differences. It's incorporating most key terminology in Storage network and related issues in concise manner. Though more detail is not expected from this small size book, it would be good to have more technical information then abstract one. This book is good for quick introduction to NAS and SAN market but can't be used as bible of either field.
