Important addition to any network library

Like any book on availability this one addresses a number of interrelated topics - service level management, capacity and performance management, and specific techniques for achieving high availability.I like this book because it introduces proven engineering techniques in the first five chapters, beginning with a discussion of availability and building upon this foundation with necessary math, a discussion of network topologies, factors that affect availability, and end-to-end availability management. This part of the book will not only provide valuable information to network professionals at all levels of experience and knowledge, but is also applicable to IT operations managers and infrastructure support professionals who are involved in service level management.The remaining chapters are realistic case studies that are based on Cisco products that give excellent insights into attaining and managing availability in various environments - a small ISP, a large enterprise and an enterprise VoIP network.In addition to a wealth of information, this book comes with a CD ROM that contains a generic hardware availability and reliability calculator (in Microsoft Excel format - I was able to use it with an older version of Excel 97, which is a nice touch), and a terse PDF of instructions. It also contains worked examples of this spreadsheet for various Cisco products, the most valuable of which in my opinion are the Cisco 12000 processing engine and system level calculation spreadsheets that accompany Chapter 9 "A Large VoIP Network: An Availability Analysis".This book is essential reading, and is nicely augmented by "High Availability Networking with Cisco" by Vincent C. Jones (ISBN 0201704552) because that book takes the fundamentals and expands them into complex scenarios. If you're new to networking get this book before getting Jones' book, but if you're experienced, get both.

Unbelievable what this book has in it.

Sometime when I pick a book to review I have no idea what information is contained within the pages. So much to my surprise I was extremely pleased to find this 240 page book so chock full of useful information. What I found after reading this book is that the author must be very experienced in the High Availability networking and the information was detailed, but also written at the level for the beginner or intermediate technician. Taking the reader from the topologies and hardware, to environment and design, the author gives you 10 scenarios from real world situations. Finally there was a cd included with a System High Availability Calculator (SHARC) to calculate reliability and availability. Overall I have most certainly learned something new from a well organized and well documented book - great job!
