Rating is subjective

Have you wander why one person rates the same book with five while another person with one star. The rating system is subjective, that's why. When you buy the book at brick and mortar store you can return pages and make your purchasing decision. At Amazon.com you have only few pages you can view. It would be great if Amazon gives its readers a better opportunity. Please do read comments and person's background then compare with your needs.
As far as this book concerns I gave 5 stars for a beginner reader's use. But this book is not a design manual for Data Centers and it is a very task to write a manual. It involves Electrical Engineering, Information System, Mechanical Engineering, Fire Suppression, and Local and National Codes knowledge to create a manual.
