Designing Generation 4.0 Data Centers: The Engineers’ Approach to Solving Business Challenges…continued

Part # 2

(A couple of years ago, when our Data Center Services’ Research & Engineering team within Microsoft’s Global Foundation Services (GFS) group kicked off the Generation 4.0 Data Center design project, we began with the question of: What are the primary business challenges facing data center deployments today? ) Here’s the rest of the story….

Question Everything

Often the application of technology involves as much innovation as the technology itself. Rather than reinvent the wheel we looked at our industry’s journey thus far. We started by questioning everything up to and including the roof and the very definition of a data center. With a lot of prior art in modularization, some of which has already been applied to the IT industry, we saw a good fit. The military has been deploying portable ground stations with IT servers and communications equipment for decades. And for some time now telecom companies have deployed pre-manufactured buildings which are then assembled on site as central offices.

As part of our design project we met to discuss the modular solution space with a group of folks from our Infrastructure Services team within GFS , including members of our hardware, data center operations, development, engineering, risk management, and security teams, as well as our internal product groups. (The original Gen 4.0 team from the two-day session is 100 percent intact and still working at Microsoft, by the way.) We knew we could modularize the server room, which we now call Server PACs. The challenge became how to modularize the entire facility. So we created other PACs: Generator PACS, Medium Voltage Switchgear PACs, UPS PACs, etc. Next, we developed the system electrical one-line diagrams and mechanical schematics for our four data center classes.

Then we had to take these single lines and schematics and break them into logical modules for the components to reside in. This may seem easy but represents a shift in thinking from a building where, for instance, we would have a UPS room and associated equipment and switchgear manufactured by multiple vendors and put it physically in sometimes separate modules. The challenge became how to shift from a traditional construction mindset to the new, modularized manufacturing mindset. Maintainability is a large part of reliability in a facility, and became a key differentiator between the four classes. Our A Class infrastructure, which is not concurrently maintainable and is on basically street power and unconditioned air, will require scheduled downtime for maintenance. The cost, efficiency, and time-to-market targets for A Class are very aggressive and a fraction of what the industry has come to see as normal today. We realized that standardization and reuse of components from one class to the next was a key to improving cost and efficiency. Our premise was that the same kit of parts (or modules) should be usable from class to class. These modules (in this new mindset) can be added to other modules to transition within the data center from one class to the next.

Standardize to Differentiate

With the standardization of a kit of modular parts it is possible to supply different types of facilities—large-scale, mega-data centers and edge or mini-data centers—from the same supply chain. A pre-manufactured set of solutions can thus reduce costs through economy of scale. Traditionally, because of network and site service costs it has been more cost effective to deploy 40 megawatts of capacity in a single location than to build 40 individual 1-megawatt facilities. In a pre-manufactured model that isn’t necessarily the case. The use of a production-line approach, while at the same time simplifying interconnections through the right modularization of the components, can drive costs down for mini- as well as mega-data center facilities. Of course the fixed costs of site development must be considered, but we are finding that the production-line approach is significantly narrowing the difference in cost per megawatt for mega- and mini-data centers.

We realize that innovation will come from many sources, and so we are partnering with technology leaders in the vendor community, as well as our customers, to help drive and deliver the benefits of this new approach. We believe it is crucially important to develop this technology now due to the many constraints on our environment and economy globally. However, we do not have unlimited resources to drive this alone. Through industry partnership and collaboration we will be able to accelerate the adoption of modular data centers and deliver the benefits of technology, software, and services to more people.

Imagine the possibilities of bringing affordable computing to corners of the world that have no power or IT grid to speak of today. This could be done using modular power plants such as fuel cells and modular data centers in partnership with wireless technology where there is a lack of existing infrastructure (for example). Applications could become virtual in the local modular data center, or the cloud, and the thousands of services and applications it holds could be provided via low-cost devices. Great opportunities like being able to provide a $100 or a lot less laptop (or new access devices not yet invented) per child could then be achieved sooner. A modular data center could quickly be deployed to support millions of virtual applications and at the same time access the power of the Internet and cloud services for a large population that does not have that opportunity today. Personally, I am very excited about these possibilities and believe I am fortunate to be working on this technology at this time.

We look forward to continued collaboration with our industry participants.

Microsoft's Generation 4 Data Center Vision - the Architects' Perspective

Microsoft's Generation 4 Data Center Vision - the Architects' Perspective

By David Gauthier, Data Center Infrastructure Architect and Christian Belady, Principal Power and Cooling Architect, Microsoft Corp.

On Tuesday, December 2, our Global Foundation Services team went public with our Generation 4 Modular Data Center Vision and over the past week a lot of great discussions and questions have been posed from our industry colleagues. Today, we wanted to address some of those questions and share more insight on our Gen 4 plan via a video interview we did with Adam Bomb, a Technical Evangelist at Microsoft's TechNet Edge.

Some people got the impression that this announcement was solely about a containerized server room rather than a re-thinking of the entire infrastructure. The goal of Gen 4 is to modularize not only the server and storage components, which a number of companies are already doing, but also to modularize the infrastructure, namely the electrical and mechanical systems. The real innovation is around the commonality, manufacturing, supply chain and integration of these modules to provide a plug-and-play infrastructure along with modularized server environments. In addition, it is focused on scaling the infrastructure with the business demands, smoothing capital investment, and driving costs down as shown by the following chart.

While we expect these modular innovations to reduce capital investments by 20%-40% or more depending on class, we also expect considerable reductions in operating expenses related to electricity and water consumption. Designing from the start for environmental sustainability has allowed us to focus on using less construction material up front, less energy and water during operation, and also allows us to recycle and reuse components at the end of their useful life. No longer will we be governed by the initial decisions made when constructing the facility. We will have almost unlimited use and re-use of the facility and site. We will also be able to use power in an ultra-fluid fashion moving load from critical to non-critical as use and capacity requirements dictate.

More importantly, any IT or infrastructure vendor's products that meet our specs can be used interchangeably, thus providing a means for global sourcing and a competitive and innovative supplier landscape. As our team has already discussed pretty thoroughly, Microsoft is already reaping some of the benefits of modularity with server containers and we are confident that further modularization will afford us additional benefits when applied to the 'back of house'.

Some people have questioned whether an open air facility is as safe against natural disasters as a traditional concrete and steel structure. We believe that it can be and we are currently taking these factors into account as part of our heat map criteria site selection activities. Of course, we also expect that our modular approach affords tremendous flexibility in addressing site specific conditions as needed. Another significant benefit modularity offers is a smaller system failure zone versus a traditional data center. For example, a fire in a data center could bring the whole facility down in traditional construction (or have the fire department activate the emergency power off). Alternatively, in a modularized data center the fire could actually be isolated to only a subset of modules and thus provide greater resiliency.

We recognize that these types of architectures may not work for every application or every data center provider out there. We're not saying this will be the right way or the wrong way, just our way - and it may not be for everyone. We are confident about this direction meeting the needs of our data center environment and we hope that it sets the stage for continued healthy and dynamic dialog and sharing in this industry.

Our Vision for Generation 4 Modular Data Centers – One way of Getting it just right . . .

msdcblog — Tue, 02 Dec 2008 05:13:00 GMT

The following posting originally appeared on Michael Manos' Loose Bolts blog.

Data Centers are a hot topic these days. No matter where you look, this once obscure aspect of infrastructure is getting a lot of attention. For years, there have been cost pressures on IT operations and this, when the need for modern capacity is greater than ever, has thrust data centers into the spotlight. Server and rack density continues to rise, placing DC professionals and businesses in tighter and tougher situations while they struggle to manage their IT environments. And now hyper-scale cloud infrastructure is taking traditional technologies to limits never explored before and focusing the imagination of the IT industry on new possibilities.

At Microsoft, we have focused a lot of thought and research around how to best operate and maintain our global infrastructure and we want to share those learnings. While obviously there are some aspects that we keep to ourselves, we have shared how we operate facilities daily, our technologies and methodologies, and, most importantly, how we monitor and manage our facilities. Whether it’s speaking at industry events, inviting customers to our “Microsoft data center conferences” held in our data centers, or through other media like blogging and white papers, we believe sharing best practices is paramount and will drive the industry forward. So in that vein, we have some interesting news to share.

Today we are sharing our Generation 4 Modular Data Center plan. This is our vision and will be the foundation of our cloud data center infrastructure in the next five years. We believe it is one of the most revolutionary changes to happen to data centers in the last 30 years. Joining me, in writing this blog are Daniel Costello, my director of Data Center Research and Engineering and Christian Belady, principal power and cooling architect. I feel their voices will add significant value to driving understanding around the many benefits included in this new design paradigm.

Our “Gen 4” modular data centers will take the flexibility of containerized servers—like those in our Chicago data center—and apply it across the entire facility. So what do we mean by modular? Think of it like “building blocks”, where the data center will be composed of modular units of prefabricated mechanical, electrical, security components, etc., in addition to containerized servers.

Was there a key driver for the Generation 4 Data Center?

If we were to summarize the promise of our Gen 4 design into a single sentence it would be something like this: “A highly modular, scalable, efficient, just-in-time data center capacity program that can be delivered anywhere in the world very quickly and cheaply, while allowing for continued growth as required.” Sounds too good to be true, doesn’t it? Well, keep in mind that these concepts have been in initial development and prototyping for over a year and are based on cumulative knowledge of previous facility generations and the advances we have made since we began our investments in earnest on this new design.

One of the biggest challenges we’ve had at Microsoft is something Mike likes to call the ‘Goldilock’s Problem’. In a nutshell, the problem can be stated as:

The worst thing we can do in delivering facilities for the business is not have enough capacity online, thus limiting the growth of our products and services.

The second worst thing we can do in delivering facilities for the business is to have too much capacity online.

This has led to a focus on smart, intelligent growth for the business — refining our overall demand picture. It can’t be too hot. It can’t be too cold. It has to be ‘Just Right!’ The capital dollars of investment are too large to make without long term planning. As we struggled to master these interesting challenges, we had to ensure that our technological plan also included solutions for the business and operational challenges we faced as well.

So let’s take a high level look at our Generation 4 design

Are you ready for some great visuals? Click here for the Microsoft 4th Gen Video. It’s a concept video that came out of my Data Center Research and Engineering team, under Daniel Costello, that will give you a view into what we think is the future.

From a configuration, construct-ability and time to market perspective, our primary goals and objectives are to modularize the whole data center. Not just the server side (like the Chicago facility), but the mechanical and electrical space as well. This means using the same kind of parts in pre-manufactured modules, the ability to use containers, skids, or rack-based deployments and the ability to tailor the Redundancy and Reliability requirements to the application at a very specific level.

Our goals from a cost perspective were simple in concept but tough to deliver. First and foremost, we had to reduce the capital cost per critical Mega Watt by the class of use. Some applications can run with N-level redundancy in the infrastructure, others require a little more infrastructure for support. These different classes of infrastructure requirements meant that optimizing for all cost classes was paramount. At Microsoft, we are not a one trick pony and have many Online products and services (240+) that require different levels of operational support. We understand that and ensured that we addressed it in our design which will allow us to reduce capital costs by 20%-40% or greater depending upon class.

For example, non-critical or geo redundant applications have low hardware reliability requirements on a location basis. As a result, Gen 4 can be configured to provide stripped down, low-cost infrastructure with little or no redundancy and/or temperature control. Let’s say an Online service team decides that due to the dramatically lower cost, they will simply use uncontrolled outside air with temperatures ranging 10-35 C and 20-80% RH. The reality is we are already spec-ing this for all of our servers today and working with server vendors to broaden that range even further as Gen 4 becomes a reality. For this class of infrastructure, we eliminate generators, chillers, UPSs, and possibly lower costs relative to traditional infrastructure.

Applications that demand higher level of redundancy or temperature control will use configurations of Gen 4 to meet those needs, however, they will also cost more (but still less than traditional data centers). We see this cost difference driving engineering behavioral change in that we predict more applications will drive towards Geo redundancy to lower costs.

Another cool thing about Gen 4 is that it allows us to deploy capacity when our demand dictates it. Once finalized, we will no longer need to make large upfront investments. Imagine driving capital costs more closely in-line with actual demand, thus greatly reducing time-to-market and adding the capacity Online inherent in the design. Also reduced is the amount of construction labor required to put these “building blocks” together. Since the entire platform requires pre-manufacture of its core components, on-site construction costs are lowered. This allows us to maximize our return on invested capital.

In our design process, we questioned everything. You may notice there is no roof and some might be uncomfortable with this. We explored the need of one and throughout our research we got some surprising (positive) results that showed one wasn’t needed.

In short, we are striving to bring Henry Ford’s Model T factory to the data center. http://en.wikipedia.org/wiki/Henry_Ford#Model_T. Gen 4 will move data centers from a custom design and build model to a commoditized manufacturing approach. We intend to have our components built in factories and then assemble them in one location (the data center site) very quickly. Think about how a computer, car or plane is built today. Components are manufactured by different companies all over the world to a predefined spec and then integrated in one location based on demands and feature requirements. And just like Henry Ford’s assembly line drove the cost of building and the time-to-market down dramatically for the automobile industry, we expect Gen 4 to do the same for data centers. Everything will be pre-manufactured and assembled on the pad.

And did we mention that this platform will be, overall, incredibly energy efficient? From a total energy perspective not only will we have remarkable PUE values, but the total cost of energy going into the facility will be greatly reduced as well. How much energy goes into making concrete? Will we need as much of it? How much energy goes into the fuel of the construction vehicles? This will also be greatly reduced! A key driver is our goal to achieve an average PUE at or below 1.125 by 2012 across our data centers. More than that, we are on a mission to reduce the overall amount of copper and water used in these facilities. We believe these will be the next areas of industry attention when and if the energy problem is solved. So we are asking today…“how can we build a data center with less building”?

We have talked openly and publicly about building chiller-less data centers and running our facilities using aggressive outside economization. Our sincerest hope is that Gen 4 will completely eliminate the use of water. Today’s data centers use massive amounts of water and we see water as the next scarce resource and have decided to take a proactive stance on making water conservation part of our plan.

By sharing this with the industry, we believe everyone can benefit from our methodology. While this concept and approach may be intimidating (or downright frightening) to some in the industry, disclosure ultimately is better for all of us.

Gen 4 design (even more than just containers), could reduce the ‘religious’ debates in our industry. With the central spine infrastructure in place, containers or pre-manufactured server halls can be either AC or DC, air-side economized or water-side economized, or not economized at all (though the sanity of that might be questioned). Gen 4 will allow us to decommission, repair and upgrade quickly because everything is modular. No longer will we be governed by the initial decisions made when constructing the facility. We will have almost unlimited use and re-use of the facility and site. We will also be able to use power in an ultra-fluid fashion moving load from critical to non-critical as use and capacity requirements dictate.

Finally, we believe this is a big game changer. Gen 4 will provide a standard platform that our industry can innovate around. For example, all modules in our Gen 4 will have common interfaces clearly defined by our specs and any vendor that meets these specifications will be able to plug into our infrastructure. Whether you are a computer vendor, UPS vendor, generator vendor, etc., you will be able to plug and play into our infrastructure. This means we can also source anyone, anywhere on the globe to minimize costs and maximize performance. We want to help motivate the industry to further innovate—with innovations from which everyone can reap the benefits.

To summarize, the key characteristics of our Generation 4 data centers are:

Scalable
Plug-and-play spine infrastructure
Factory pre-assembled: Pre-Assembled Containers (PACs) & Pre-Manufactured Buildings (PMBs)
Rapid deployment
De-mountable
Reduce TTM
Reduced construction
Sustainable measures
Map applications to DC Class

We hope you join us on this incredible journey of change and innovation!

Long hours of research and engineering time are invested into this process. There are still some long days and nights ahead, but the vision is clear. Rest assured however, that we as refine Generation 4, the team will soon be looking to Generation 5 (even if it is a bit farther out). There is always room to get better.

So if you happen to come across Goldilocks in the forest, and you are curious as to why she is smiling you will know that she feels very good about getting very close to ‘JUST RIGHT’.

Generations of Evolution – some background on our data center designs

We thought you might be interested in understanding what happened in the first three generations of our data center designs. When Ray Ozzie wrote his Software plus Services memo it posed a very interesting challenge to us. The winds of change were at ‘tornado’ proportions. That “plus Services” tag had some significant (and unstated) challenges inherent to it. The first was that Microsoft was going to evolve even further into an operations company. While we had been running large scale Internet services since 1995, this development lead us to an entirely new level. Additionally, these “services” would span across both Internet and Enterprise businesses. To those of you who have to operate “stuff”, you know that these are two very different worlds in operational models and challenges. It also meant that, to achieve the same level of reliability and performance required our infrastructure was going to have to scale globally and in a significant way.

It was that intense atmosphere of change that we first started re-evaluating data center technology and processes in general and our ideas began to reach farther than what was accepted by the industry at large. This was the era of Generation 1. As we look at where most of the world’s data centers are today (and where our facilities were), it represented all the known learning and design requirements that had been in place since IBM built the first purpose-built computer room. These facilities focused more around uptime, reliability and redundancy. Big infrastructure was held accountable to solve all potential environmental shortfalls. This is where the majority of infrastructure in the industry still is today.

We soon realized that traditional data centers were quickly becoming outdated. They were not keeping up with the demands of what was happening technologically and environmentally. That’s when we kicked off our Generation 2 design. Gen 2 facilities started taking into account sustainability, energy efficiency, and really looking at the total cost of energy and operations. No longer did we view data centers just for the upfront capital costs, but we took a hard look at the facility over the course of its life. Our Quincy, Washington and San Antonio, Texas facilities are examples of our Gen 2 data centers where we explored and implemented new ways to lessen the impact on the environment. These facilities are considered two leading industry examples, based on their energy efficiency and ability to run and operate at new levels of scale and performance by leveraging clean hydro power (Quincy) and recycled waste water (San Antonio) to cool the facility during peak cooling months.

As we were delivering our Gen 2 facilities into steel and concrete, our Generation 3 facilities were rapidly driving the evolution of the program. The key concepts for our Gen 3 design are increased modularity and greater concentration around energy efficiency and scale. The Gen 3 facility will be best represented by the Chicago, Illinois facility currently under construction. This facility will seem very foreign compared to the traditional data center concepts most of the industry is comfortable with. In fact, if you ever sit around in our container hanger in Chicago it will look incredibly different from a traditional raised-floor data center. We anticipate this modularization will drive huge efficiencies in terms of cost and operations for our business. We will also introduce significant changes in the environmental systems used to run our facilities. These concepts and processes (where applicable) will help us gain even greater efficiencies in our existing footprint, allowing us to further maximize infrastructure investments.

This is definitely a journey, not a destination industry. In fact, our Generation 4 design has been under heavy engineering for viability and cost for over a year. While the demand of our commercial growth required us to make investments as we grew, we treated each step in the learning as a process for further innovation in data centers. The design for our future Gen 4 facilities enabled us to make visionary advances that addressed the challenges of building, running, and operating facilities all in one concerted effort.
