Download the authoritative guide: Enterprise Data Storage 2018: Optimizing Your Storage Infrastructure
A short chapter on securing a SAN provides information on security from both a hardware and software perspective. This is perhaps the only chapter of the book where it seemed that more information could have been provided. There are also excellent chapters on SAN topologies, designing and building SANs, and problem isolation and management.
A chapter on iSCSI offers a comprehensive coverage of the topic - certainly enough for anyone interested in learning the fundamentals. As well as acknowledging that iSCSI has its place in the SAN environment, it goes on to explain why iSCSI is needed and, at a moderately technical level, how it works. There is also a detailed Design Considerations and Security Requirements table which provides a interesting insight into the 'why's' of iSCSI.
The book finishes off with a look at what the future holds for SANs, including overviews of technologies such as DWDM, SoIP and Infiniband. As with the rest of the book, the information is grounded in the here and now, and details the emerging technologies that are in the process of establishing themselves as opposed to being futureware.
The book is healthily populated with excellent and detailed diagrams. In addition to the diagrams there are a small number of black and white photographs that show (Cisco, of course) storage networking equipment. While it is nice to see what products actually look like, the photos are taken from sufficiently far away as to make it impossible to discern any detail on the devices. As such they are of limited value.
A limited glossary includes brief descriptions of commonly used storage terms. Although it would be nicer to have a more comprehensive glossary, it is nice to see that Cisco does not use the 'one glossary fits all' approach adopted by some other technical book publishers. The book has only one appendix, the oddly named Raid Technology and Fibre Channel Vendors. Quite how the two are related enough to be included in the same appendix is unclear, though it does not devalue the content of the information provided which in both cases is excellent.
The author's style throughout the book is factual and to the point, which is fine for this type of publication. There is little to cause you to question the knowledge or understanding of the topic displayed by the author or the technical reviewers.
While SAN Fundamentals is not cheap, people who use their reference material on a regular basis will appreciate the hard cover - an unusual feature for a book of this size. Those hoping for a discount off the cover price from an online bookseller will have to look long and hard however - none of the bookseller sites we checked were offering a discount.
Cisco Press books have always been about a no-nonsense 'just the facts' approach and SAN Fundamentals is no exception. In simple terms, it is what you would expect a SAN fundamentals book from Cisco to be - high quality, easy to read, up to date and laden with facts.
