Although it addresses the fundamentals of SCSI configuration, this book's primary value is as a no-kidding electrical engineering and programming text on the low-level characteristics of SCSI communication. This is the book you want if you're involved in designing physical SCSI devices or writing software drivers for SCSI devices. The book goes heavy on tables that list jumper settings, as well as state diagrams and signal references. Despite its commendable depth, it's easy to read and likely contains the answers to your SCSI questions, even if they don't have to do with low-level signaling. --David Wall
Topics covered: The Small Computer System Interface (SCSI) family of hardware interconnection standards, viewed mainly (but not entirely) in great detail. An overview of SCSI (with special focus on the SCSI-3 standard), along with coverage of cables and terminators, software device drivers, RAID implementations under SCSI, and troubleshooting hints. The Advanced SCSI Programming Interface (ASPI) tutorial and reference is great, as is the practical comparison of IDE and SCSI disks.

The book also has, by far, the finest explanation of RAID (Redundant Array of Independent Drives) that I have ever seen (and I have read many books on computer hardware). The only unfortunate aspect of a book of this nature is that with the time involved in publishing a book, the book is almost out dated by the time it hits the shelves. SCSI is currently in an explosive growth state with new standards coming out at least yearly. A companion website with information on the latest SCSI standards would be a very welcome addition to this book. Fortunately though, since SCSI is an evolutionary standard, having a firm grasp on SCSI fundamentals and early standards -- which this book will most certainly give you - it is relatively easy to learn the new standards.
In summary, "The Book of SCSI" is an outstanding technical book that is well written, easy to read, and full of detail and information. Whether you are a computer novice or seasoned professional, you will learn something from this book.
The book has the latest information on SCSI 3 (including Ultra2/LVD), RAID, SCSI test equipment, and device drivers.
The book also has a good mix of SCSI information on the different operating systems including DOS, Macintosh, NetWare, Unix, and four flavors of Windows. One thing missing from "The Book of SCSI", however, is any mention of Windows 2000 and ASPI for Win64. Is Mr. Field perhaps saving this information for "The Book of SCSI" - 3rd Edition?
This time around, a SCSI project landed on my desk. So how did this book stack up against the others? Here is my opinion.
This book is, hands down, the best written introductory book on SCSI available. The authors take pains to clearly describe the evolution of SCSI, why you should use it, how to connect SCSI devices, and troubleshooting. They even describe why a cable has to be terminated, in detail. Administrators and technicians studying for the A+ exam will simply love this book.
Programmers, on the other hand, will come up wanting. The actual protocol isn't discussed, only ASPI. Examples are given in assembly (for DOS), and Delphi. ASPI is discussed for DOS, Win 3.1, NT, and OS2.
If you are looking for an introductory book that explains SCSI in basic, high-level terms, this is your book. On the other hand, if you are seeking a book to help you jump start your application development, look elsewhere.
