• Continuous rapid growth and adoption of data hungry IT equipment is escalating the need for greater amounts of energy to keep data centers running and highly available.

• Researchers estimate 50 billion new devices connected to the internet by 2020 and will surpass 100 billion devices by 2025.

• Data Center Industry consumes about 2% of our power usage today, however global IT is at 7%.

Improving Availability, Resiliency While Reducing Energy Demand

If the global IT industry were a country, only China and the United States would contribute more to climate change, according to a Greenpeace report investigating "the race to build a green internet,“ Data Centers are one of the top five energy consumers in the world, surpassing many countries and by 2040 will be responsible for 14% of global carbon emissions.

Things you will learn in this presentation:• New research findings and projections for data center energy

consumption; and where energy stands in Data Center owners priorities• Measuring PUE and introducing more meaningful metrics.• We can save energy while making our Data Centers more resilient.• Greener technology must be sustainable on its own and won’t be

successful long term if it doesn’t make us more resilient


Data Center Operations Best Practices

Where does green technology fit it?

Shutting down zombie servers and increasing

server utilization to save energy while improving

resiliency has been popular

• Only 28% consider environmental issues in the selection of data center technology


Is our most popular Data Center Efficiency metric PUE contradictory to some of our energy saving goals?

“In most cases, improving IT equipment power usage can result in the greatest overall improvement in power usage efficiency.” However, according to Henrique Cecci, research director at Gartner, although the PUE metric focuses on the data center energy efficiency of the facilities’ components, it does not provide insights into energy efficiency improvements at the IT equipment level.

(CADE) = Facility Efficiency (FE) x Asset Efficiency (AE)Facility Efficiency (FE) is equal to (Facility Energy Efficiency) x (Facility Utilization) Asset Efficiency (AE) is equal to (IT Energy Efficiency) x (IT utilization)

(DCcE) Data Center Compute Efficiency and its sub-metric, Server Compute Efficiency (ScE) = metrics enable data center operators to determine the efficiency of their compute resources

(pPUE) and (mPUE) measure the mechanical energy efficiency in comparison to the IT and facility energy usage

Enthalpy = thermodynamic quantity equivalent to the total heat content of a system equal to the internal energy of the system plus the product of pressure & volume

42% of Data Center Management knows what their PUE is


Renewables take the headlines in our $20B/year Data Center Construction Industry yet…

Driven by significant new capital investment by cloud computing companies and colocation operators, new data center capacity is rapidly being added across a number of U.S. metropolitan markets.

Markets such as Virginia and Chicago are served by utilities with extremely low amounts of renewable energy powering their respective generation mix.

Space required for a 1 MW of solar PV power plant = 4 acres

Space required for a 2 MW wind turbine = 1.5 acres

Solar & wind require natural gas plants, hydro-electric dams, batteries or some other form of reliable power be ready at a moment’s notice to start churning out electricity when the wind stops blowing and the sun stops shining.

Hot Spots of US Data Center Investment:


Some Greener Technologies may be Geographically and/or Resource influenced

The water risk to investors of California-based companies operating data centers will not affect them gradually, said Julie Gorte, senior vice president of sustainable investing at Pax World Management LLC. “It will probably come in one big splashy moment,” she said.

Do I need redundant systems that can operate year round?


Some Greener Technologies need specific Resources such as continuous natural gas & hydrogen

• Do you have the capacity and quality of natural gas required?

• Do you have the staff and tools for managing your Microgrid?

• Do you have the capital to build your own MicroGrid and will the utility still back you with power when needed?

Investment in the fuel cell industry has dipped in recent years, shrinking 85 percent between 2015 and 2016, according to data from Bloomberg New Energy Finance.“Essentially what we want to do is get out of R&D as soon as possible and actually use them to power the data center, we hope to do that as soon as possible,” Sean James of Microsoft.


Do you have to turn on/off and manage the economization?

• Active eco-mode approach pushes efficiency up above 97 percent in some cases. It keeps the inverter and rectifier in an active state, which means the inverter is providing output that matches the bypass and is ready to accept the load immediately.

• Due to technology limitations, some UPS systems have to turn off the inverter before turning on the bypass or turn off the bypass before turning on the inverter. This is commonly referred to as an interrupted transfer.


Uptime and Redundancy Continue to Be Critical Considerations2018 Data Center Knowledge survey respondents indicated they take power uptime very seriously:

• 80% of respondents indicated they’re at least at N+1 electrical • In next 12-36 months, about 30% will incorporate N+2 levels of redundancy.

We see similar levels when it comes to cooling redundancy: • 78% indicated that they have at least N+1 cooling redundancy:

• In next 12-36 months, 27% will be leveraging at least N+2 levels of redundancy.

Should we only consider efficiencies that also improve resiliency?

Some equipment can operate more efficiently with added redundancy - VFDs are 2 fans operating at 50% capacity more efficient than one at 100% capacity


Low hanging energy conservation measure with an effective ROI while improving resiliency has been airflow management• It is the separation of the cold air supply and hot

return air streams that allow us to increase the Delta T and maximize the capacity of the cooling

• A simple raised floor grommet to close a typical 9” x 6” grommet can save ~$500 in energy

• Once we optimize the environment by fully separating the air streams we can look to save 4% in energy costs for every degree the set point temperature is raised

• 67% are reporting increased rack densities but with an average density of 7.3KW there isn’t a need for direct liquid cooling yet


Next step could be taking containment down to the small room or micro level

There are efficiency gains and capacity is maximized in our small rooms and rack level as we have experienced in the Data Center


What are we losing in not conditioning all of our facility power?

Solutions exist today to regulate and balance voltage so we don’t draw more current and create a peak when there is a blip or sag in voltage all while putting KVAR back on our grid for 10-15% energy savings.


UPS systems reduce THD total harmonic distortion – should we look to reduce this elsewhere?

Technology is developing constantly, requiring more use of special electronic loads. The development of modern chip-driven equipment is based on non-linear loads causing distortion of the harmonics in the electric current.

All of the extra electricity consumed that is out of phase is either returned to the grid or grounded. Both cases result in a waste.


Can results of reducing Harmonic Distortion, blips, sags in voltage & use of KVAR be measured?

• With an oscilloscope on the panel or service we can see how harmonics filters clean up the sign wave

• Below voltage is regulated and balanced through a series of capacitors to reduce current draw and peak demand.


• Some EC fans are designed ‘ground up’ such that the aerodynamics, motor, and drive electronics are all designed to work as a system.

• It is only when a fan mfgdesigns and builds the complete air mover, that the entire system is optimized to its fullest.

• The result is in an ultra efficient EC system with the best reliability and maintenance free. As well documented product performance with true “plug and play” applications.

With moving air consuming 50%+ of the data center lost power, can fan power be reduced while improving reliability?


• With these optimized EC air movers installed along with improvements on applying the fan to the system - energy consumption can be reduced by more than 50%. Whitepapers can be shared to expand on this.

• Air Handling Units (AHUs), Exhaust Fans, CRACS, In-Row Coolers, Condensers, Cooling Towers, Powered/Active Floor Tiles and more all benefit from EC Technology.

Best EC systems have integrated ModBus, PID controller, 0-10V as well as range in performance from a few watts up to 13.8kW / 18HP … enabling all air moving applications for the Data Center to be efficient, controllable, and reliable.

Are there limitations to what applications can see fan power savings?


3 Key Things You Have Learned During this Session

1. Where saving energy stands in Data Center owners priorities

2. We can save energy while making our Data Centers more resilient.

3. Greener technology must be sustainable on its own and won’t be successful long term if it doesn’t make us more resilient.
