Mr. Poniatowski covers all the hot topics of "Green IT" which is relevant to the times we live in today - The book looks at what every IT professional is dealing with, and that's power or lack of it due to the ever increasing demand, e-waste and it's plague on our planet, going paperless, TCO (Total Cost of Ownership), ROI (Return on Investment) and other related topics, all centered around the "Green" movement. This book is well thought out and addresses the key issues in a manner which provides a clear understanding of various choices that can be made to help make the environment better. Information Technology (IT) is the lifeblood of every aspect of our civilization. By considering the importance of Green IT as one of the parameters to be addressed during their decision making and making some green IT choices, Executives can help minimize the impact of Information Technology installations on the environment. I found this book very informative.
I doubt that there are any computer centers or IT departments today that aren’t having budget problems. Yet if you look at the ordinary site, you’ll find that some application gets defined, they guy a server to handle it, over time everything begins to grow so that there are more servers, more storage, more everything. This procedure seems to happen with each new application. So you soon have a room full of servers using power, using cooling, taking up space. And since the old servers never seem to die, you will find that there is a collection of one and two processor, one and two core servers still being used.
I found the most useful part of his book is an analysis of what these servers are costing and the savings that are available by converting them to newer more efficient hardware. I know, that makes me sound like the HP/Dell/IBM salesman. But it turns out to be true. The book gives some simple ways to calculate the overall cost of using a batch of older servers or consolidating the power you need in fewer more powerful units. The analysis includes how much memory do you really need, from the smaller servers that probably only have two to four gig of memory, and memory has gotten cheap. I haven’t looked, but I doubt that you can buy servers that small any more. Some of his other comments make a lot of sense. For instance buying printers that have automatic duplex (both sides of the sheet) printing save lots of paper.
Most of the authors analysis concentrates on what’s available on the latest equipment. It may be that you do not need the latest and greatest. Look a little at used equipment, sometimes organizations are selling surprisingly late date hardware at very low prices. I recently saw an HP DL 585 quad CPU with quad cores and 32 GB of memory for sale at something like $129. Basically this book will help you to analyze what you really need.
Foundations of Green IT comes at a very important time in the IT industry and I think Mr Poniatowski does a great job of bringing the most pressing issues forward. Cost savings are paramount to organizations looking for an edge in today's marketplace and this book highlights such cost saving solutions as virtualization and consolidation. I think it's also very telling that the book looks forward to cloud computing and the future of consolidation as the pace of change is ever increasing. It's a very helpful resource for both IT professionals and those looking to learn more about making your infrastructure more "green".
I found Mr. Poiniatowski's book to be informative and well-written. The chapters were well organized with just the right amount of illustrations to bring the information together. Green IT is a very hot topic these days. Mr. Poiniatowski expounds on this topic in a way that is insightful, thoughtful and to the point.
I have read many technical books over the years but this is one of the first that I actually found entertaining. I would recommend it to anyone in IT who wants to help save the planet while saving money at the same time!
Foundations of Green IT: Consolidation, Virtualization, Efficiency and ROI in the Data Center is a pick for any college-level computer collection strong in networking issues. It comes from a team of leading Green IT consultants and provides technical information and case studies for consolidation, better design, and reducing PC waste. Technical specifics make this a powerful recommendation.
This is a well planned, informative and well written book on how to truly leverage the power of today's technology to "do more with less". I know I learned a lot from both, contributing and reading this book.
As a contributor and technical reviewer of this book, I received one of the first copies off the press. I'm very impressed with the final product and can strongly recommend it as a valuable resource for any CIO/CTO, IT Director, or Data Center Manager looking for ideas on how to retool for the future.
The book presents an organized review of several key areas of IT infrastructure, detailing where and how current products can be leveraged to save power, cooling, space, and money.
Real life examples and case studies are combined with ROI reports to show how the concepts can be applied and what they can mean to the bottom line.
this is a great reference book for those IT professionals that are looking for ideas on server and storage consolidation and overall improvement of datacenter efficiencies. this is a must have for any CIO's bookshelf. It provides a good general reference on a variety of existing and emerging technologies as they relate to adopting ways to save power, cooling, and space in the datacenter.
Receiving a copy off the press I got the opportunity to be one of the first to read the finished product. The book breaks down all aspects of network environments as it pertains to storage, backup, and security. This book is a great addition to any Data Center Admin's library as it contains tons of useful info for any environment.
