The book reviews the latest developments in facilities, server, storage, networking, and monitoring technologies and provides a roadmap of how each can be used to create next-generation data centers that combine efficiency with scalability ... Schulz's book provides an excellent primer for those wanting to understand how to create data centers for this new paradigm. -Kurt Marko, in Processor, March 2009, Vol. 31, No. 11 What I like about Schulz's approach is that he doesn't really pass judgment on whether or not you should re-adjust your IT initiatives around some greener-good agenda. He's focused more so on illustrating how some of the technologies you're already considering for the good of your business - virtualization, blade platforms, cloud computing power management - might otherwise be pretty cool for the environment, too. -Heather Clancy, Green Tech Pastures, in ZDNet, February 26, 2009 Greg Schulz has presented a concise and visionary perspective on the Green issues. He has cut through the hype and highlighted where to start and what the options are. A great place to start your green journey and a useful handbook to have as the journey continues. -Greg Brunton, EDS/An HP Company I must admit that I have been slightly skeptical at times, when it comes to what the true value is behind all of the discussions on 'green' technologies in the data center. As someone who has seen both the end user and vendor side of things, I think my skepticism gets heightened more than it normally would be. This book really helped dispel my skepticism. ...extremely well organized and easy to follow. Each chapter has a very good introduction and comprehensive summary. This book could easily serve as a blueprint for organizations to follow when they look for ideas on how to design new data centers. It's a great addition to an IT Bookshelf. -Dr. Steve Guendert, Global Solutions Architect, Brocade Communications


A green and virtual data center relies on the efficient usage of underlying physical resources to achieve energy savings. Green servers, storage, and networks deliver the performance, availability, and responsiveness for all types of application needs and requirements. This book provides strategies and blueprints for enabling and deploying environmentally friendly next-generation data centers. Addressing multiple technology domains and disciplines, it looks at design and implementation tradeoffs using various best practices and technologies to sustain application and business growth while maximizing resources, such as power, cooling, floor space, storage, server performance, and network capacity.The book shows how to make server and storage virtualization energy efficient and still be able to support a diversity of high-performance applications. It also explores performance and capacity planning in a virtual environment that supports resource-demanding applications, such as OLTP and streaming media.

5.0 von 5 Sternen Timely information for CIO's and IT Directors 16. Oktober 2009
Von Paul D. Collins - Veröffentlicht auf Amazon.com
Format:Gebundene Ausgabe
Greg Schulz has delivered with both a timely and informative book. With the economic meltdown occurring in 2008 every company has become focused on cost containment both for Cap Ex and Op Ex and the data center is in forefront. This is taking place at the same time as heighten awareness of our planets ecology and the impact of IT and data centers. As Schulz states in his summary chapter: "The objective is to lower cost, boost productivity, and improve service delivery to meet performance and availability objectives in a flexible or agile manner that also helps the environment."
In the first chapter Schulz coins the acronym PCFE for power, cooling, floor space and environmental to aggregate the IT infrastructure issues that are core to green initiatives. As I read through the book I substituted PC Fe for Politically Correct Iron because in my mind it reflects what Schulz calls the "green gap". This "green gap" is the separation of ecological and economic factors that are tied to the data center. On one hand we have the concerns about global warming, green-house gases, and carbon emissions while on the other we have data growth, power and cooling cost, stock holders looking for profits and the perceived cost to be green. The case is presented that this gap is more one of language and attitude as opposed to reality. If IT directors and facility managers implement best practices to design and run their data centers they will find in most cases they align with green objectives because it makes business sense.
The book is divided into four sections. In the first section there is a summary of the issues facing CIOs and IT directors around energy consumption, safety requirements for the disposal or equipment, and what green IT means. The second section looks at current trends in data center infrastructure and how they can be effectively monitored and managed. The third examines the technologies which are enabling virtualization and driving current trends like cloud computing. This is Mr. Schulz's area of core competency and has the most in depth coverage. In the final portion of the book there are practical applications of the concepts discussed in the other sections. I found the format to be a good organization that kept key areas together and the overall coverage of the topics to be of sufficient depth. I would recommend this book to anyone wants to understand the impact of "green IT" as well how the convergence of a number of technologies has created potential for virtual IT infrastructure.

5.0 von 5 Sternen Great book to understand green and virtualized next generation data centers 8. Mai 2009
Von Zen Kishimoto - Veröffentlicht auf Amazon.com
Format:Gebundene Ausgabe|Verifizierter Kauf
Overall this is a well-structured and organized book with comprehensive coverage of necessary technologies and practices, including virtualization to understand next-generation data centers. Some technical contents require an IT background, but the book will certainly give you a good understanding of current data-center problems and solutions and what next-generation data centers will require to mitigate their environmental impact.

Because of the wide variety of subjects, several shorter versions of the book will be a good addition. In addition, I would like to see new topics discussed in the next version of the book.

5.0 von 5 Sternen Practical Advice on Green Data Centers 11. Mai 2009
Von Thomas M. Coughlin - Veröffentlicht auf Amazon.com
Format:Gebundene Ausgabe
Operating expenses for a data center often exceed initial caital expenses. In today's economy reducing operating expenses is a major priority for IT professionals. Greg Shulz's book, The Green and Virtual Data Center is an excellent reference book for creating and running cost effective and environmentally sensitive data centers.

The author shows us the basic operations, hardware and expenses for a modern data center. He covers the infrastructure as well as direct expenses. Infrastructure expenses such as HVAC, UPS and power conditioning can account for more than half the total operating costs of a data center. By controlling hardware efficiency, extending the allowable temperature range and move efficient cooling suing external air and water as well as better server and storage placement, these infrastructure operating expenses can be significantly reduced.

Virtualization is a popular way to consolidate data center resources. This technology abstractes storage and servers to act as a common pool that can be centrally managed and dynamically allocated. Using the extensive suggestions in theis book, data center administrators can increase their use of these pooled resources to 80% or higher.

A shown in this book, deduplication and compression of data on storage systems reduces overall stoarge system growth. Combining these methods for reducing overall storage demand with appropriate implementation of storage hierarchies and usage of new storage technologies such as MAID and solid state storage can reduce hardware as well as operating expenses.

The book includes a useful glossary as well as helpful references and tips in the appendices. This book is a good investment and will remain a much used reference for data center administers and IT managers.
5.0 von 5 Sternen A good view into the green virtualized data center 11. Februar 2011
Von Andrew Sanchez - Veröffentlicht auf Amazon.com
Format:Gebundene Ausgabe|Verifizierter Kauf
The book The Green and Virtual Data Center by Greg Schulz includes a vast array of topics pertaining to data center elements and virtualization from fundamentals to practice. The author covered energy efficiency metric basics and continued with the application of PCFE to the current practices in IT operations. The material is relevant and practical yet not overly technical; however, it is also not intended for readers with no prior working knowledge of data center infrastructures or IT in general. The main theme of the book is to analyze current data center operations to find opportunities where energy consumption can be reduced by cutting waste or misallocation of energy, minimizing heat production, introduce a well-designed virtualization strategy to maximize computing output from existing resources, and to adopt technologies and techniques that facilitate efficiency and availability.

The value of The Green and Virtual Data Center lies primarily in its conceptual application, rather than technical application, to the issue of how to get more out of existing computing and storage capacity while at the same time reducing the energy utilization. He states that the intent is not to "green wash" the data center but rather to serve as a very real means of adding to the bottom line and have IT be an active player in the organization's added resource allocation rather than merely a consumer of resources.

Early in the book, Schulz dispels any notion of "green" as a political or PR maneuver but rather sees the implementation of an energy reduction strategy as a business decision while helping make operations more effective and productive. To serve that purpose, the book includes statistics and charts but not as a basis of the concept but rather as an aid to reinforce the main thesis if the book. Schulz also makes it very clear that going green should be all about business and the progress of the industry with the added benefit of being positive to the environment in the way of reduced carbon emissions and recycling. To this Schulz provides and well evolved lecture on the basics of power generation and the different types of fuels involved. He also mentions the electrical grid and the different distribution plants.

In the second section, the book covers virtualization almost exclusively. The topics are relevant but certainly not all of them will be around for long as he gets quite granular when discussing snapshots and data replication. While the current virtualization practices are a good foundation, Schulz perhaps should have covered them from a different angle such as the main underlying concepts only and leave out the details as those will most likely change and some already have such as the rapid advancement of cloud computing, distributed clouds and cloud infrastructure management. Of course, the cloud still has to exist in data centers but some may look be architected very differently than described by Schulz. The Green and Virtual Data Center only includes a few pages on cloud computing without any real new content.

Schulz also discusses virtual data center energy management but using the typical mechanized methods. He describes the types of power sources, energy consumers and devices but does not get into real detail relating to intelligent management mechanisms such as those promoted by The Green Grid or the intelligent management systems developed by IT software vendors. He also does not cover any real concepts relating to intelligent energy routing, provisioning or monitoring. Because of this omission, The Green and Virtual Data Center remained rather neutral and descriptive in nature but missed one of the potentially forthcoming revolutions in IT and perhaps business in general. Nevertheless, Schulz correctly describes cooling as the highest consumer of energy in the data center. He also provides good insight into rack cooling, backup systems, PDUs, and how to determine energy needs and usage.

The Green and Virtual Data Center covers several topics that are better suited for a different book such as physical security, networking, and hardware. Schulz does not particularly specialize or offer any innovative solutions or ideas on how to maximize resource utilization. The material he presents is not original but rather a compilation of what is out in the industry. What Schulz does quite well is put the material together and synthesize ideas from various disciplines into the area of data center operations.

Some topics that Schulz omits almost entirely are the data center management and structure as well as operations as they relate to personnel and processes. These areas would have offered potential practical applications to increasing efficiencies in the data center by way of improved practices, management, processes or structure. He offers some dialogue on outsourced data centers and some mentions of management but not much else.

Schulz's book is an adequate reference resource for individuals who work in data centers. It may also be a valuable source as an inside view to those who do not work in data centers. However, The Green and Virtual Data Center also includes material that is not entirely relevant to the topic of green and virtual data centers but valuable to know. The most value in the book lies in the definition of concepts and trends in virtualization, even if at times it gets overly granular but not to the extent of a VMWare manual. Data center practitioners will get value out of the book but IT and business readers in general may find some topics out of their scope yet a valuable resource that delivers an insider's view of the energy efficient and virtualized data center.
