Saving Money with Green IT: Time To Invest In Information Factories

There is a good and timely article titled Green IT Can Save Money, Too over at Business Week that has a familiar topic and theme for those who read this blog or other content, articles, reports, books, white papers, videos, podcasts or in-person speaking and keynote sessions that I have done..

I posted a short version of this over there, here is the full version that would not fit in their comment section.

Short of calling it Green IT 2.0 or the perfect storm, there is a resurgence and more importantly IMHO a growing awareness of the many facets of Green IT along with Green in general having an economic business sustainability aspect.

While the Green Gap and confusion still exists, that is, the difference between what people think or perceive and actual opportunities or issues; with growing awareness, it will close or at least narrow. For example, when I regularly talk with IT professionals from various sized, different focused industries across the globe in diverse geographies and ask them about having to go green, the response is in the 7-15% range (these are changing) with most believing that Green is only about carbon footprint.

On the other hand, when I ask them if they have power, cooling, floor space or other footprint constraints including frozen or reduced budgets, recycling along with ewaste disposition or RoHS requirements, not to mention sustaining business growth without negatively impacting quality of service or customer experience, the response jumps up to 65-75% (these are changing) if not higher.

That is the essence of the green gap or disconnect!

Granted carbon dioxide or CO2 reduction is important along with NO2, water vapors and other related issues, however there is also the need to do more with what is available, stretch resources and footprints do be more productive in a shrinking footprint. Keep in mind that there is no such thing as an information, data or processing recession with all indicators pointing towards the need to move, manage and store larger amounts of data on a go forward basis. Thus, the need to do more in a given footprint or constraint, maximizing resources, energy, productivity and available budgets.

Innovation is the ability to do more with less at a lower cost without compromise on quality of service or negatively impacting customer experience. Regardless of if you are a manufacturer, or a service provider including in IT, by innovating with a diverse Green IT focus to become more efficient and optimized, the result is that your customers become more enabled and competitive.

By shifting from an avoidance model where cost cutting or containment are the near-term tactical focus to an efficiency and productivity model via optimization, net unit costs should be lowered while overall service experience increase in a positive manner. This means treating IT as an information factory, one that needs investment in the people, processes and technologies (hardware, software, services) along with management metric indicator tools.

The net result is that environmental or perceived Green issues are addressed and self-funded via the investment in Green IT technology that boosts productivity (e.g. closing or narrowing the Green Gap). Thus, the environmental concerns that organizations have or need to address for different reasons yet that lack funding get addressed via funding to boost business productivity which have tangible ROI characteristics similar to other lean manufacturing approaches.

Here are some additional links to learn more about these and other related themes:

Should Everything Be Virtualized?

Storage I/O trends

Should everything, that is all servers, storage and I/O along with facilities, be virtualized?

The answer not surprisingly should be it depends!

Denny Cherry (aka Mrdenny) over at ITKE did a great recent post about applications not being virtualized, particularly databases. In general some of the points or themes we are on the same or similar page, while on others we slightly differ, not by very much.

Unfortunately consolidation is commonly misunderstood to be the sole function or value proposition of server virtualization given its first wave focus. I agree that not all applications or servers should be consolidated (note that I did not say virtualized).

From a consolidation standpoint, the emphasis is often on boosting resource use to cut physical hardware and management costs by boosting the number of virtual machines (VMs) per physical machine (PMs). Ironically, while VMs using VMware, Microsoft HyperV, Citrix/Xen among others can leverage a common gold image for cloning or rapid provisioning, there are still separate operating system instances and applications that need to be managed for each VM.

Sure, VM tools from the hypervisor along with 3rd party vendors help with these tasks as well as storage vendor tools including dedupe and thin provisioning help to cut the data footprint impact of these multiple images. However, there are still multiple images to manage providing a future opportunity for further cost and management reduction (more on that in a different post).

Getting back on track:

Some reasons that all servers or applications cannot be consolidated include among others:

Performance, response time, latency and Quality of Service (QoS)
Security requirements including keeping customers or applications separate
Vendor support of software on virtual or consolidated servers
Financial where different departments own hardware or software
Internal political or organizational barriers and turf wars

On the other hand, for those that see virtualization as enabling agility and flexibility, that is life beyond consolidation, there are many deployment opportunities for virtualization (note that I did not say consolidation). For some environments and applications, the emphasis can be on performance, quality of service (QoS) and other service characteristics where the ratio of VMs to PMs will be much lower, if not one to one. This is where Mrdenny and me are essentially on the same page, perhaps saying it different with plenty of caveats and clarification needed of course.

My view is that in life beyond consolidation, many more servers or applications can be virtualized than might be otherwise hosted by VMs (note that I did not say consolidated). For example, instead of a high number or ratio of VMs to PMs, a lower number and for some workloads or applications, even one VM to PM can be leveraged with a focus beyond basic CPU use.

Yes you read that correctly, I said why not configure some VMs on a one to one PM basis!

Here’s the premise, todays current wave or focus is around maximizing the number of VMs and/or the reduction of physical machines to cut capital and operating costs for under-utilized applications and servers, thus the move to stuff as many VMs into/onto a PM as possible.

However, for those applications that cannot be consolidated as outlined above, there is still a benefit of having a VM dedicated to a PM. For example, by dedicating a PM (blade, server or perhaps core) allows performance and QoS aims to be meet while still providing the ability for operational and infrastructure resource management (IRM), DCIM or ITSM flexibility and agility.

Meanwhile during busy periods, the application such as a database server could have its own PM, yet during off-hours, some over VM could be moved onto that PM for backup or other IRM/DCIM/ITSM activities. Likewise, by having the VM under the database with a dedicated PM, the application could be moved proactively for maintenance or in a clustered HA scenario support BC/DR.

What can and should be done?
First and foremost, decide how VMs is the right number to divide per PM for your environment and different applications to meet your particular requirements and business needs.

Identify various VM to PM ratios to align with different application service requirements. For example, some applications may run on virtual environments with a higher number of VMs to PMs, others with a lower number of VMs to PMs and some with a one VM to PM allocation.

Certainly there will be for different reasons the need to keep some applications on a direct PM without introducing a hypervisors and VM, however many applications and servers can benefit from virtualization (again note, I did not say consolation) for agility, flexibility, BC/DR, HA and ease of IRM assuming the costs work in your favor.

Additional general to do or action items include among others:

Look beyond CPU use also factoring in memory and I/O performance
Keep response time or latency in perspective as part of performance
More and fast memory are important for VMs as well as for applications including databases
High utilization may not show high hit rates or effectiveness of resource usage
Fast servers need fast memory, fast I/O and fast storage systems
Establish tiers of virtual and physical servers to meet different service requirements
See efficiency and optimization as more than simply driving up utilization to cut costs
Productivity and improved QoS are also tenants of an efficient and optimized environment

These are themes among others that are covered in chapters 3 (What Defines a Next-Generation and Virtual Data Center?), 4 (IT Infrastructure Resource Management), 5 (Measurement, Metrics, and Management of IT Resources), as well as 7 (Servers—Physical, Virtual, and Software) in my book “The Green and Virtual Data Center (CRC) that you can learn more about here.

Welcome to life beyond consolidation, the next wave of desktop, server, storage and IO virtualization along with the many new and expanded opportunities!

Summer Book Update and Back to School Reading

August and thus Summer 2009 in the northern hemisphere are swiftly passing by and start of a new school year is just around the corner which means it is also time for final vacations, time at the beach, pool, golf course, amusement park or favorite fishing hole among other past times. In order to help get you ready for fall (or late summer) book shopping for those with IT interests, here are some Amazon lists (here, here and here) for ideas, after all, the 2009 holiday season is not that far away!

Here’s a link to my Amazon.com Authors page that includes coverage of both my books, "The Green and Virtual Data Center" (CRC) and "Resilient Storage Networks – Designing Scalable Flexible Data Infrastructures" (Elsevier).

Click here to look inside "The Green and Virtual Data Center" (CRC) and or inside "Resilient Storage Networks" (Elsevier).

Its been six months since the launch announcement of my new book "The Green and Virtual Data Center" (CRC) and general availability at Amazon.com and other global venues here and here. In celebration of the six month anniversary of the book launch (thank you very much to all who have bought a copy!), here is some coverage including what is being said, related articles, interviews, book reviews and more.

Article: New Green Data Center: shifting from avoidance to becoming more efficient IT-World August 2009

wsradio.com interview discussing themes and topics covered in the book including closing the green gap and shifting towards an IT efficiency and productivity for business sustainability.

Closing the green gap: Discussion about expanding data centers with environmental benefits at SearchDataCenter.com

From Greg Brunton – EDS/An HP Company: “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.”

From Rick Bauer – Storage Networking Industry Association (SNIA) – Education and Technology Director”
“Greg is one of the smartest “good guys” in the storage industry.
He has been a voice of calm amid all the “green IT hype” over the past few years. So when he speaks of the possible improvements that Green Tech can bring, it’s a much more realistic approach…”

From CMG (Computer Measurement Group) MeasureIT
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.

The book is 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. – Reviewed by Stephen R. Guendert, PhD (Brocade and CMG MeasureIT). Click here to read the full review in CMG MeasureIT.

From Tom Becchetti – IT Architect: “This book is packed full of information. From ecological and energy efficiencies, to virtualization strategies and what the future may hold for many of the key enabling technologies. Greg’s writing style benefits both technologists and management levels.”

From MSP Business Journal: Greg Schulz named an Eco-Tech Warrior – April 2009

From David Marshall at VMblog.com: If you follow me on Linked in, you might have seen that I had been reading a new book that came out at the beginning of the year titled, “The Green and Virtual Data Center” by Greg Schulz. Rather than writing about a specific virtualization platform and how to get it up and running, Schulz takes an interesting approach at stepping back and looking at the big picture. After reading the book, I reached out to the author to ask him a few more questions and to share his thoughts with readers of VMBlog.com. I know I’m not Oprah’s Book Club, but I think everyone here will enjoy this book. Click here to read more what David Marshal has to say.

Green IT Confusion Continues, Opportunities Missed!

I continue to see those looking for fast silver bullets in the quest to be green, efficient, optimized or sustainable while addressing issues ranging from power/energy, cooling, floor-space/footprint, EH&S (environmental health & safety) not to mention recycling. Yet, I’m also continued to be amazed by the focus and emphasis around reduce as in reduce your capacity and your performance or processing capabilities in the form of consolidation or aggregation along with energy avoidance which for some is applicable.

However, there is also the other side of the tale which is shifting from avoidance to becoming more efficient, that is doing more with what you have or with less while boosting productivity. For example, having a server or processor that can do more work in the same or smaller physical footprint drawing the same or less energy and requiring less cooling is a form of reducing overall impact yet boosting productivity. The same can be done with data and I/O networks, storage and even software.

Similar to automobiles after the 1970s oil and energy crisis, the focus was on reduction, conservation and avoidance as the form of being efficient. Over time, this approach gave way to levering more efficient engines and vehicles that boosted the MPG city and highway, change in driving or usage habits, awareness of issues including applicable metrics and energy costs, as well as the continuing quest for alternative fuels.

This is no different than what is happening with the IT organizations or compute focused entities in that there has been an initial focus of avoidance to meet short term tactical requirements, not to mention all of the green hype of a few years ago. Today there is a shift taking place towards efficiency and awareness that optimization and efficiency is more than consolidation, that it also includes boosting productivity as part of achieving reduced energy and cooling demands.

How this can be done is to leverage multiple different techniques including new servers with processors that have intelligent power management (IPM) also known as adaptive voltage scaling (AVS) or other marketing terms enabling variable performance and energy consumption. For example, vary clock cycles and turn on cores when needed, then to turn off cores, slow clock speed down when there is less work to be done. Likewise there are improvements with cooling closer to the heat source ranging from leveraging inert liquid cooling inside the cabinet of computers to surface attached cooling to emerging micro cooling located inside silicon. There is a fascination with using virtualization to consolidate and reduce servers that are underutilized, which again is applicable for some environments and applications.

However not all servers including many that are underutilized lend themselves to being consolidated for various reasons including quality of service (QoS) or performance, security, vendor support or software compatibility, politics or finance among others. This however does not mean that they cannot be virtualized, it more than likely mean that they cannot be consolidated. There is a common myth that virtualization equals consolidation and vice versa, however virtualization can also be used for abstraction, transparency, emulation and enabling agility including support for load-balancing, scale-up and scale-out performance oriented clustering among other uses. Thus there is another side of virtualization and that is to achieve efficiency, life beyond consolidation.

Needless to say there are many more technologies and techniques to address various issues now along with those that are emerging. The good news in all of this is the growing awareness that there are many different faces or facets of being green. That green wash and green hype may be on the endangered species list, that green means more than reducing carbon footprints or recycling or energy avoidance. That green is really about shifting and becoming more efficient, more optimized to support more processing, more work in a cost effective manner to sustain growth on a go forward basis. For high performance compute (HPC) or other large scale IT organizations, there is a notion that small improvements on a large broad scale have significant impact.

Some organizations are in pursuit of technologies of solutions that promise significant saving ratios over small sets or instances, solutions that provide smaller reduction or savings over a larger basis can prove to be more effective. For example, if power is a concern, powering down servers or storage that promises 85-100% savings might only be applicable to less than 5% of the devices. However, if 85-100% of the devices can be upgraded to newer models that boost productivity by 5-15% (or more) in the same or smaller footprint, using 5-15% (or more) less power, the results add up quickly. Think of it this way, a 1% saving for an environment using 1,000 kilo watt hour (kWh) or 1mWh of energy is a savings of 10kWh. The point being that for large environments, don’t forget to look at small savings that apply to a large installed base that then add up to big benefits.

The net result is that one can pursue being green or being perceived as being green which can have a high cost, or, can pursue various efficiency that help the overall organization by boosting productivity, helping the top and bottom line, doing more in a smaller footprint and guess what, the result is not only economic, it’s also environmental positive. Thus, the byproduct of shifting towards efficiency (and not just avoidance) is to become green!

Determining Computer or Server Energy Use

Recently I posted a response to a question over at IT Knowledge Exchange (e.g. ITKE) about how to determine power or energy use.

In a nutshell:

Depending on what you are looking for, or trying to accomplish, you may, or may not need a formula per say.

For example, if all you need to know is how many volts, amps, watts, kva, or btu’s are used by a particular computer or other IT device for that matter, first things first check the “tag” or “label” on the device as well as included documentation, or, on-line spec sheets and documentation.

There are also some measuring devices including among others Kill A Watt that you can plug a device into and see volts, amps, watts, and so forth.

Ok, that might have been the obvious and easy part, now on to the next step.

Often a name plate may give kva however not watts, or perhaps amps and volts however not kva or some other metric. This is where the various conversion formulas come into play.

For example, if you know volts and amps, you can get watts, if you know kva along with watts, amps or volts, you can derive the others, or, if you have btus, you can watts, or if you know watts you can get btus and so forth.

Btu/Hour = watts * 3.413
Watts = Btu/Hour * 0.293
Watts = Amps * Volts
Volts = Watts / Amps
Amps = Watts / Volts
VoltAmps (Va) = Volts * amps
KVA = (Volts * Amps) / 1000

Here’s a link to some additional conversions and formulas that along with many others are found in my new book “The Green and Virtual Data Center” (CRC).

www.thegreenandvirtualdatacenter.com/greenmetrics.html

In “The Green and Virtual Data Center” (CRC). book, there is an entire chapter on metrics, where and how to find them, formulas, conversions as well as other related items including determining energy costs, carbon footprints, cooling and more across servers, storage, networks, facilities along with associated management tools.

Storage Effiency and Optimizaiton – Balancing Time and Space

Storage I/O trends

Here’s a link to the presentation I recently delivered at the Spring 2009 Minneapolis/St. Paul area CMG (Computer Measurement Group – CMG) March 20th, 2009 hosted by Nexus Information Systems and organized by Tom Becchetti. The theme of the event was "Is your storage efficient? There are many ways to rate your storage, how does yours stack up?". Tom organized a great event as usual with a diverse set of speakers for the well attended event graciously hosted by Keith Norbie of Nexus at their Minnetonka facility. The title of my presentation was "Storage Efficiency: Mirror Mirror On The Wall, Who or What is The Most Efficient of Them All? Finding the Correct Balance" that looked at balancing the need to reduce (or maximize) space (utilization) with time (performance) to meet different requirements including maintaining quality of service, response time and availability.

Keeping in mind that there is no such thing as a data or I/O performance recession, there is a common myth that storage optimization or efficiency is all about driving up storage space capacity utilization which can be true for some environments, applications, data or storage types. However there is also the need to maintain or boost performance, reduce response time and latency, doing more work in a more productive and efficieny manner. Not all data or storage can be consolidated to boost utilization without concern for degrading or in any other way penalizing performance, response time or availability.

Thus it is about time and space, that is, balancing data movement and processing rates with storage space capacity utilization and that sometimes, more is not better for performance when it comes to ratios or the number of components in a solution.

Likewise there is the need to balance energy avoidance with energy efficient, balancing the need to store more data in a smaller footprint using less energy and the need to process more data in less time efficiently for productivity.

These and other related themes are expanded on in more detail in my book "The Green and Virtual Data Center" (CRC). These and other related themes will covered in one of my upcoming presentations (The Other Green — Storage Efficiency and Optimization) at StorageDecisions in Chicago the week of June 1st, 2009, as well as in various seminars and events that I will be involved in the coming weeks and months.

Thanks to all those who helped organize, support, sponsored, presented and attended the recent CMG event, look forward to seeing or hearing from you all again soon.

March and Mileage Mania Wrap-up

Today’s flight to Santa Ana (SNA) Orange County California for an 18 hour visit marks my 3rd trip to the left coast in the past four weeks that started out with a trip to Los Angeles. The purpose of today’s trip is to deliver a talk around Business Continuance (BC) and Disaster recovery (DR) topics for virtual server and storage environments along with related data transformation topics themes, part of a series of on-going events.

Planned flight path from MSP to SNA courtesy of Northwest Airlines, now part of Delta

This is a short trip to southern California in that I have to be back in Minneapolis for a Wednesday afternoon meeting followed by keynoting at an IT Infrastructure Optimization Seminar downtown Minneapolis Thursday morning. Right after Thursday morning session, its off to the other coast for some Friday morning and early afternoon sessions in the Boston area, the results of which I hope to be able to share with you in a not so distant future posting.

Where has March gone? Its been a busy and fun month out on the road with in-person seminars, vendor and user group events in Minneapolis, Los Angles, Las Vegas, Milwaukee, Atlanta, St. Louis, Birmingham, Minneapolis for CMG user group, Cincinnati and Orange County not to mention some other meetings and consulting engagements elsewhere including participating in a couple of webcast and virtual conference/seminars while on the road. Coverage and discussion around my new book "The Green and Virtual Data Center" (CRC) continues expand, read here to see what’s being said.

What has made the month fun in addition to traveling around the country is the interaction with the hundreds of IT professionals from organizations of all size hearing what they are encountering, what their challenges are, what they are thinking, and in general what’s on their mind.

Some of the common themes include:

There’s no such thing as a data recession, however the result is doing more with less, or, with what you have

Confusion abounds around green hype including carbon footprints vs. core IT and business issues

There is life beyond consolidation for server and storage virtualization to enable business agility

Security and encryption remain popular topic as does heterogeneous and affordable key management

End to end IT resource management for virtual environments is needed that is scalable and affordable

Performance and quality of service can not be sacrificed in the quest to drive up storage utilization

Clouds, SSD (FLASH), Dedupe, FCoE and Thin Provisioning among others are on the watch list

Tape continues to be used complimenting disks in tiered storage environments along with VTLs

Dedupe continues to be deployed and we are just seeing the very tip of the ice-berg of opportunity

Software licensing cost savings or reallocation should be a next step focus for virtual environments

Now, for a bit of irony and humor, overheard was a server sales person talking to a storage sales person comparing notes on how they are missing their forecasts as their customers are buying fewer servers and storage now that they are consolidating with virtualization, or using disk dedupe to eliminate disk drives. Doh!!!

Now if those sales people can get their marketing folks to get them the play book for virtualization for business agility, improving performance and enabling business growth in an optimized, transformed environment, they might be able to talk a different story with their customers for new opportunities…

What’s on deck for April? More of the same, however also watch and listen for some additional web based content including interviews quotes and perspectives on industry happenings, articles, tips and columns, reports, blogs, videos, podcasts, webcasts and twitter activity as well as appearances at events in Boston, Chicago, New Jersey and Providence among other venues.

To all of those who came out to the various events in March, thank you very much and look forward to future follow-up conversations as well as seeing you at some of the upcoming future events.

Plenty of Industry Firsts at VMworld Europe

Warning: Ok, I’m tiered and ready for a short vacation, so be advised, there is some industry and other tongue and check humor in this post, if you get it great, if not, don’t worry about it, ask around and someone can fill you in… ;).

So with VMworld Europe taking place in Cannes (that’s in the south of France and a nice place if you have not been there yet), rest assured, there will be a flurry of product, service and other announcements, some of which will use the usual industry first, industry only only, truly unique and the other usual claims. Unfortunately I wont be in Cannes as I will be in Florida next week doing a couple of keynote and sessions on IT optimization with some IT professionals in the Tampa and Miami areas.

What’s fun about being pre-briefed under NDA and/or embargo (are they the same) is hearing what the different vendors are or will be announcing and what can be even more fun, is hearing their claims of being 1st or thinking or believing they are 1st when in reality one may have just gotten off of the phone with someone else who is announcing something similar.

Rest assured, there will be some good and useful and with the right qualifiers, new, unique, 1st and so forth announcements next week especially for those who take the time to dig in to the details. So do that, look at the announcements, better yet, if you are at VMworld Europe, stop by and see the various vendors, their new solutions and ask the questions and dig into the details to learn more.

Now having said all of that, with the applicable qualifiers, I will say, that to my knowledge, from what I’m aware of based on briefings and other information that I can disclose, the industry first European appearance in the south of France in Cannes at a VMworld conference will see the first appearance and giveaway promotion by a vendor of my new book "The Green and Virtual Data Center" (CRC) which will be taking place at the StorMagic booth (or stand) in the Innovators area of the expo hall. (did I get enough qualifiers in to make it an industry 1st? – That was some humor BTW ;) ).

I think in their category and for what they are doing (VM and storage infrastructure, data protection and management) the StorMagic SvSAN is rather interesting and deserves a closer look. While on the surface it looks like what others are doing, that is simply moving a storage software stack that might otherwise run in a tin wrapped software appliance (that’s a server or controller) vs. repackaging and stuffing into a silicon wrapped (e.g. software and memory enabled) virtual machine (VM) as many others have done. On closer inspection, SvSAN is actually enabling management of internal RAID adapter cards with integration into VMware control/management interfaces to simplify and streamline hardware, software and storage resources. (yes yes yes, I know, everybody else is already doing that – BTW – That was another attempt at some humor! ;) )

However don’t take my word, check it out yourself and let me know. Stop by the StorMagic both or stand, say hello, tell them that Greg from StorageIO sent you, signup for a giveaway of my new book, ask them to show you why they have something new and different with their new version of SvSAN VM and Storage Infrastructure management tool. You then can be the judge as to how unique and enabling their new announced capabilities are for broad market VMware environments.

Disclosure, StorMagic is not nor have they ever been a client or sponsor directly or indirectly via 3rd or 4th parities. that is, unless you consider them buying some books from my publisher or one of my publishers distributors in some way shape or form an in-direct means. (Now for some, that was an industry inside joke, for others, well, lets leave it at that for now, nuff said ;) ).

Ok, time to get packed and head out for a long weekend and get ready for next weeks busy schedule. For those heading to VMworld, enjoy and hope to see or talk with you soon. For those in Tampa and Miami, hope to see you next week, for everyone else, check out my events page as there are many events coming to cities and venues near you soon. Enjoy and try to have some fun, and to quote Wolf Gang Puck, "Live Love and Eat" :) .

Cheers – gs

Do you have your copy of “The Green and Virtual Data Center” yet?

For those not familar with my new book, "The Green and Virtual Data Center" (Auerbach), or, for those who have already ordered your copy (Thank You and look for them to arrive soon) as today marks the offical publication date, or, I guess you could say the birthday for "The Green and Virtual Data Center".

Thus, I am pleased to share with you the news about the formal launch and publication (read the press release) of my new book, “The Green and Virtual Data Center”, which is released today by Auerbach/CRC-Press and is available at Amazon, Barnes & Noble, Borders, CRC-Press and other venues around the world.

The book focuses on the idea that IT infrastructure resources configured and deployed in a highly virtualized manner can be combined with other techniques and technologies to achieve a simplified and cost-effective delivery of IT services in a clean, green, and profitable manner. ?The Green and Virtual Data Center? covers these technologies and techniques that todays data centers should be considering while trying to maximize resources, such as power, cooling, floor space, storage, server performance, and network capacity.

Some of the topics include:
• Energy and data footprint reductions
• Cloud-based storage and computing
• Intelligent and adaptive power management
• Server, storage, and networking virtualization
• Tiered servers for storage, network, and data centers
• Energy avoidance and energy efficiency
