It's Time to Collaborate

In December of 2011 we hosted an exclusive Data Center Pulse collaboration session one day before we held the opening of the eBay Data Center, Project Mercury. The goal of this collaboration session was to bring 50 of our Data Center peers together to deep dive into the project, the lessons learned and discuss/debate the relevance of these concepts being applied to their data centers. We also did something new in this session - we allowed 5 vendors to participate. Wait, before you cry foul and question why we would go against our charter, I need to lay out some context. We invited the design and construction teams (EDI Ltd, AHA Consulting Engineers, Winterstreet Architects & DPR) to participate in the closed door session with members. These were the engineers that did the actual work, not sales, marketing, etc. They had very relevant insight and learnings into the challenges and lesson learned. That session went very well with lots of people discussing and debating the implementation and practicality to application in their environment. Once we finished that session, we had parallel deep dives with the Dell and HP technologists who were directly responsible for the Container, Server and Storage designs and implementations in Project Mercury. It was engineers talking to engineers.

This collaboration session turned out be one of the most productive we've had to date. Below is a video with footage from the event, a quick tour of the Project Mercury Data Center and Interviews with some of the attendees.


We are hosting our next DCP Summit on Monday, March 5, 2012 in San Jose. You can email to receive the password to register. View the summit details here. One of the topics at the summit will be the Project Mercury Case Study published by the Green Grid on February 27, 2012.

Three Years Later

DCP was formed on September 8, 2009. It seems like only yesterday when we started this! Quite a bit has happened since that date. We have over 2200 core members in 66 countries representing over 1000 companies in almost every industry. Our original charter has remained the same; Influence the industry through the insight of the consumer - the data center owner/operator. Join Mark Thiele and I as we reflect back on the three years and address how we plan to get back to basics with DCP in 2012.


Is Public Cloud Computing Green – Or at least Greener than Traditional IT?

Unfortunately, there isn't a simple answer to the "Is Public Cloud Greener" question as the only real answer is "it depends".  At the core of the question is that assumption that because you're theoretically using fewer physical machines more effectively, that you are thereby greener or more efficient.  However, even if we stay with that assumption, when you dig into the details of what being "greener" really means, you'll see that there's still no easy answer.

In order for cloud to be greener, it has to accomplish two things at a very high level:

  • Use less power, people, and resource than it's none cloud equivalent to do the same work
  • And, use power that is at least as clean, if not cleaner than the power you were using

While many of us make the assumption that the first bullet is true, we really have no way of knowing whether the second one is, unless the provider offers this information in some verifiable and transparent way.

The above discussion and the detail that supports it are covered very well in a recent blog/presentation done by a friend and fellow Data Center Pulse member Tom Raftery.  I highly recommend spending a few minutes with Tom's blog and presentation if you'd like to increase your understanding of the nuances of setting expectations with SPs, and creating or managing sustainable and green IT solutions.

Great job Tom, keep up the good work.


Why Enterprises Will Force Down the Cost of Virtualization

Force it's such a strong word, but it definitely applies if my reasoning has any basis in reality.

The point of this blog is to illustrate that regardless of the intrinsic value of any given tool in the IT tool chest, once it's implemented it becomes a cost. Now, please don't read this the wrong way, I'm not an advocate of the thinking that IT is merely a place that helps us cut the cost of IT. What I am saying is that once you've effectively implemented a new technology solution, managing the on-going costs becomes a factor in your survival.

In this case the target area is IT server infrastructure costs:



Power, Space, & Cooling


Management tools & Security




Historically virtualization has been assumed to be a great technology to be used to reduce your overhead costs in the following areas:


O/S (?)

Power, Space & Cooling



Notice that the following cost areas are specifically excluded


Management tools & Security

The above two items were left out of the "reduce your overhead costs" bullets because you didn't have virtualization and your management and security costs likely went up or at best stayed the same.  Now you probably asking, "so why is that important?"  It's important because, whether you actually reduced your total cost of ownership or have kept it the same (virtualization benefits), you now have a new cost basis.  Only now, a much larger percentage of your cost basis is the cost of the virtualization, where it used to be the servers.  Let's look at the issue another way using a simple example (Just a rough approximation):

Table 1: Infrastructure cost distribution as a percentage prior to virtualization


Management & Security

O/S & Tools


Power Space & Cooling







Table 2: Infrastructure cost distribution as a percentage after virtualization



Mgmt & Security

O/S & Tools


Power Space & Cooling








The above tables are only meant to be a means to show that the costs that make up your infrastructure have shifted. The shift in costs is important if for no other reason than the simple fact that the areas with the biggest percentage of cost are also the areas that get targeted the most for savings. As some might say "a target of opportunity". 

How virtualization becoming a target will force the issue

In closure, I'm simply attempting to illustrate the fact that no one in the business cares what we in IT did yesterday to reduce costs. What the business only does care about is what we're doing today. If you reduced your server costs last year finance doesn't see a line item that says "IT Guy Mark Thiele saved us 100K last year by eliminating fifty servers, so this year we leave him alone". What the CIO & finance person do see is what it costs to run IT today.  Unfortunately, that puts virtualization square in the cross hairs as a target of opportunity.

If you believe any of what I've written here, then you're likely to see why I believe customers will become more and more likely to introduce new tools into their environment. New tools invariably means multiple hypervisors, which in turn will force the dominate vendors in the space to review their pricing practices. 

Authors note:  The above aside, there are other reasons to have more than one hypervisor in your environment, as certain functions and workloads have still proven to work more effectively with specific hypervisors.


A Bus To The Future


I'll get straight to the point. I have a simple request directed to the personal and professional contacts I have established over the last 23 years. I need your help to raise $25,000 to buy a school bus for Dalit children in Patna, India. You can make your tax deductible donation through this PayPal Link:


Huh? Why do you need to buy a school bus for an area literally on the other side of the planet? Don't you just build and operate data centers for eBay? Yes, my day job is to build and operate the foundation that enables 100 million people to buy and sell products all over the planet...but there is something else that is equally as important. Just like Data Centers are the foundation that allow on-line businesses like eBay to grow, compete, and thrive - Education is the foundation that allows CHILDREN to grow, compete, and thrive. If children do not have access to education, then they are always at a disadvantage.

Let me explain my connection here. Earlier this year, thieves in Northern India stole a bus from the Emmanuel School in Patna. I'm sure the first question coming to your mind is why couldn't they just use their insurance to get it replaced? Sure, that sounds logical, but that's not how it works in poverty stricken areas like Patna. It can take more than nine months to get a claim paid. The payment would also not pay for a new bus. The reason this theft is personal to me is that three years ago a group of my family, friends and business contacts bought the school bus that was stolen. That simple gift enabled hundreds of extremely poor kids from remote villages to go to school. My wonderfully giving group of friends helped those kids have a shot at the future. Hundreds of Dalit children used that bus to get to the only school that would take them. Sounds like an exaggerated story, but it is not. I met many of these kids personally when I visited Patna with my mom. I know it has made a big difference in their lives. You can see the original website we published here. (please do not use the links there to donate, just use PayPal button above)

Normally, I keep my personal and professional lives separate, but I believe this is story will resonate with many in my network. We're not just going to replace the stolen bus, we're going to buy a larger one to get even more kids to school!  If you want to be a part of this, just click the PayPal donate button and give what ever you can. You can also keep up to date on the progress through our new website, Just Let Me Learn.


It is tax deductible and I will be including your name (and your company if applicable) in the new plaque we will give to the school leaders when we purchase the bus (you can also opt out of the plaque if you wish). Remember, that most companies match charitable donations by employees, so keep that in mind if you are donating personally. For corporations, please contact me directly ( if you need a differnet payment method to donate. My sincerest thanks in advance!


For those who want more background first, read on...

In 2007, I took my mom with me on a business trip to India. Her name is Sandy and she lives in the mountains of Colorado. She had never traveled outside the US before, so India was going to be an eye-opener, a BIG eye-opener! Interestingly enough, before we left, she found a number of missionaries in India over the Internet. Yes, she found people she had never met before in another country and coordinated to come visit them in their homes while I was working! That's just how she is...a tough (and stubborn) mountain woman who takes care of herself (and I love her for it). Needless to say, I explained that flying around India isn't like flying around the US. First, a 67 year old grandmother, who knows zilch about the language, culture, customs, transportation, food or any other aspect of the country doesn't just travel around alone like she's taking a trip to Starbucks. Secondly, she's my mom! I would not let her travel alone. Thankfully, we worked out a l schedule that worked for us to travel everywhere together. 

To make a long story short, it was life changing for my mom...and for me. The people of India, specifically the Dalit children and those helping them, profoundly touched us. You can see more on that in the original website I put up here. When we returned, I felt compelled to help with one immediate need. That need was to raise funds to buy a bus to get kids to the school in Patna. These kids lived in extreme poverty and had no way to get to school because they lived so far away and their parents couldn't afford to get them there. The bus we purchased gave them that opportunity. I was really pleased with the outpouring of support I received from my friends and business connections. We raised the money in less that 8 weeks. We bought the school bus and helped hundreds of kids in multiple grades get to school for more than three years. I was so thankful to all those who donated to make this happen!

But as you read earlier, the bus was stolen. It was a crushing blow to a school struggling to make ends meet. The school had to scrape up money to rent a bus to keep giving these kids the chance. A chance to raise themselves out of poverty through the gift of knowledge, the gift of an education. An education is something that many of us take for granted every day.

I look at my family, and how blessed we are. I remember back to the faces of the kids we met and the smiles they had being at that school! I want to make sure they, along with every future class, continues to have that opportunity.

Below is the PayPal donation link through the non-profit organization my mom and I setup for our work in India.


I sincerely appreciate any help you can provide! Please forward this blog to others you think would be interested in participating.

Happy Holidays,



Quicksilver Winner Announced

Today I am pleased to announced that the team of AHA Consulting Engineers & Winterstreet Architects have been selected to design Phase II of the eBay Data Center in Utah - Project Quicksilver.This was by far the toughest choice to date in this public RFP process. The five finalist teams that presented to us all had strong credentials, competent project teams and very creative designs. We took our time internally scrutinizing all of the elements of our score sheet to make our decision. As we have said in the past, we selected the team that best fit our needs at this moment in time. I am very confident that my peers will receive great benefits from seeing all five design approaches at the DCP readout session in Q1 of 2012 (stay tuned for updates). In my personal opinion, the public RFP design process has been extremely successful in driving creativity and innovation from a gamut of talented companies and individuals in the industry. The big ideas and design stretching requirements have given birth to entirely new ways to approach data center design in alignment with IT workload efficiencies. The industry is being influenced by companies like this gaining access to the challenges customers like eBay are facing in delivering value for their business. It is not just a data center facility that needs a low PUE. It is an engine connecting a 100 million users to do more than 60 billion dollars of transactions a year. IT is our business and the engine that powers it must be agile and tuned for performance and efficiency at every layer of the stack.

Below is a video introducing the project leaders and more on the process and high level design approach.

Why in Spite of the Numbers Private Cloud Will be Prominent for Years to Come


Why in Spite of the Numbers Private Cloud Will be Prominent for Years to Come

Public cloud is the way forward, it's cheaper, has better scale, probably better security than most in house IT solutions and it allows your IT team to focus on business benefit higher up the stack. So, why am I saying Private Cloud will be here for some time to come?


1.      Inappropriate Business Risk Evaluation:

a.      When it comes to protecting the company jewels, risks are to be avoided at all costs. Unfortunately, few organizations (biz or IT) have the maturity to effectively measure actual risk value. Considering the business has a very low appetite for risk to their IT systems, IT will be able to play on that risk for years to come, thereby avoiding any changes that involve moving critical IT systems/applications to Public Cloud. Lastly, there will be further missteps with the Public Cloud providers that will give internal IT all the ammunition they need to justify staying in-house.

2.      Market opportunity:

a.      Gartner predicts that the Cloud Market will be nearly $150 billion by 2014. While there are many groups making predictions (UBS, Gartner, Forrester, IDC, etc), generally speaking the prognosis is bullish to say the least. Why is the size of the market important? It's important because it drives behavior by the companies trying to maintain or grow their slice of the cloud revenue pie. Does anyone really believe that IBM, HP, Dell, NetApp, Cisco, EMC, VMware, Citrix & others are just going to lie down and let 4-5 "Amazons" be the world's clouds? They can't afford to ignore this change any more than a firefighter can ignore wind direction when fighting a forest fire. The vendors who have traditionally supported enterprise IT will do everything in their power to demonstrate the viability of private cloud. They will make it easier to setup and more efficient to own, all while heavily marketing the risks of going Public.

3.      IT isn't anywhere near being commodity yet:

a.      There has been much discussion about the "commoditization" of IT as a result of cloud. Specifically, that there won't be any need for internally built infrastructure anymore. That the future of IT will be to buy platform services from external providers and that those providers will be the ones worried about how to manage the physical assets. To some degree, this prediction is real, but I strongly believe it misses two things:

                                                    i.     The human equation: As humans still run IT, decisions about the future of IT organizations and IT roles, will be driven by "base" human needs and concerns, not purely by what might appear logical. As a leader, I learned very early that to ignore the human equation is to fail.

                                                   ii.     IT at all levels still has considerable development left in it. Even today we don't have everyone using white box servers, why is that? It's because the vendors are still offering differentiation that appeals to the buyer. I've said this before, but it bears repeating, "IT is like a painter's pallet. The painter may have the same brush, and the same colors, but will still create a new and unique painting every time".

4.      IT Organizations will respond:

a.      As IT organizations come to grips with the change Cloud brings to IT infrastructure, application ownership and organization design, they will start their own internal efforts to protect what they do. What's the best way to protect your job, innovate and improve, demonstrate how being internal and close to the business can still provide "perceived" value, regardless of what Amazon, HP, or Terramark are selling in the Cloud?

5.      10 Years to get 50% of IT into the public cloud:

a.      Over time IT organizations will change their job descriptions and ability to contribute at new levels. These role changes combined with public cloud providers becoming institutionalized will allow that move.  There will also be a slow retirement of traditional IT infrastructure specialists over the next 10 years and the majority of IT talent coming out of college will want to focus on other aspects of IT (I.e., application development, delivery and business representation). The above mentioned changes will naturally increase the percentage of IT work being done in public clouds.

6.      Within the next 10 years several large cloud providers of today will be gone or dying:

a.      This may seem like an obvious prediction, but it's not. My prediction is more related to cloud providers being caught in technology "change" traps that cost them their margins, as opposed to just being unable to execute an effective cloud offering.

I fully realize that there is controversy around this topic, but also believe that discussion and debate are the best ways to learn. Through sharing our concerns in an open forum more of us are likely to accept and internalize new ideas. In a similar vein to a blog I wrote a while back about Amazon I referenced the fact that yelling at us about what the right solution or option is isn't likely to make us change our behavior.  I look forward to your comments and tweets on this subject.


Decoding Data Center Modularity

The word du jour at least in the data center space is "Modularity". The only word used more often and loosely in the IT space is "Cloud". Even though the two words "Modularity" and "Cloud" are hyped, it doesn't mean there aren't real opportunities in both areas of technology. The trick is in understanding how the terms should be used, and where and how they should be applied. Come join me on Brightalk December 8th at 9:00 AM Pacific time A BrightTALK Channel

Quicksilver Finalists Selected

In technology, competition truly is the mother of innovation.

The first round of the Project Quicksilver competition is complete! Through the months of August and September we received 68 requests to participate in eBay's second public Data Center RFP codenamed Project Quicksilver. 61 companies qualified, and 20 submitted design proposals by the October 7th deadline. Today we have selected the 5 finalists based on a comprehensive and balanced scoring system that rated each companies submission based on the design concept, team capabilities, overall operational efficiency, sustainability and cost.



Our congratulations to the finalists (listed in alphabetical order):

  1. Advanced Design Consultants, Inc
  2. Team: Deerns & Gensler
  3. KlingStubbins
  4. M+W Group
  5. Team: Winterstreet Architects & AHA Consulting Engineers

Each of the finalists will be receiving a design fee for their efforts in reaching the finalists round. They will also have the opportunity to present their designs to the Data Center Pulse end user community in early 2012. DCP members, stay tuned for details on that upcoming event.

Once again, I am very impressed with the excitement, creativity, and thoroughness of the proposals we received. I want to personally thank all 61 of companies that embraced this challenge. Similar to Project Mercury, we received many comments from the participants expressing their apprecition on being able to participate without the constraints and traditional boundaries that are normally placed upon a Data Center design project. We also received a deluge of emails from others who are observing or would like to be incldued in all levels of the project. Throughout the process, participants were able to gain insight into how eBay, the worlds largest on-line marketplace, is addressing their uprecedneted growth and uber-efficiency requirements. The hundreds of design charrettes that have resulted from Project Mercury learnings coupled with the public RFP process through Data Center Pulse is truly breaking the mold on how the industry approaches Data Center design, consutruction, and operation. We want to thank everyone who has contributed their passion and sweat into making this possible.

In the video below, Mike Lewis, Director of Mission Critical Engineering, James Monahan, Partner at CDCDG and I discuss the Public RFP process, scoring and selection of the finalists for Project Quicksilver.

We will be selecting the winner of the Project Quicksilver design in November. Stay tuned to Project Quicksilver updates through the project page. For more information on Quicksilver and Mercury, please email
