Industry Findings and Trends

Power consumption is so significant that accommodating the increase in IT power consumption over the next five years will require the U.S. to construct 10 major power plants. If current trends continue, we will need another 20 between 2010 and 2015. Thats 30 power plants that need to be built just to accommodate the growth within IT power.

Source: Uptime Institute Forecasts indicate that unless energy efficiency is improved beyond

current trends, the federal governments electricity cost for servers and data centers could be nearly $740 million annually by 2011, with a peak load of approximately 1.2 GW.

Industry Findings and Trends People think that a $2,500 server is so cheap you dont have to worry

about it. But over three years, the cost of electricity nearly equals the cost of the server and thats without the Capital Expenditure for building the data center or the cost of running it.

Source: Uptime Institute All data centers should optimize air flow, but this step is especially

effective in legacy data centers where air flow management was not considered at build-out or where current implementation is conventional hot-aisle cold-aisle set-up. In these arrangements there is poor separation between the cold supply and hot return airstreams. Creating a physical barrier separating hot and cold airstreams to provide the highest degree of separation. Any of three approachescold aisle containment, hot aisle containment, and rack containment could provide the physical separation with each one offering its own advantages and limitations.

costs. Data Center Energy Consumption has reached the CEOs desk and will continue to become a strategic issue.

Industry Findings and Trends Data Center Facilities Reducing Data Center Power Consumption

Data Center Power Consumption is Getting More Important As a major concern power consumption/conservation increased from 48% to

55% The behavior concerning power consumption has begun to change

"When the power bill gets really significant, it ends up on the CEO's desk. "When he sees that the biggest user is IT, IT has to deal with it."

Still 28% of survey respondents don't know whether their power bill has increased or decreased though this is an improvement over the 36% who didn't know lastyear.

For the respondents who are paying attention, a majority see major increases in the power bill for their data centers. 44% have seen an increase, and 19% say the increase is greater than 10%.

Hot Aisle/Cold aisle Containment -- the practice of sealing hot aisles and cold aisles in a data center gained traction in 2009

Some data centers do hot-aisle and cold-aisle containment themselves, and some buy a system from a provider, such as Wright Line, APC and Liebert

Containment really wasn't on the radar until late last year, but already 30% of respondents have implemented it, and an additional 15% plan to next year

The cold-aisle containment strategy is slightly more popular with respondents than is hot-aisle or plenum containment

Industry Findings and Trends Increasing Computer Room Air Conditioner Performance

ASHRAE TC9.9 and Ambient Conditions Dry Bulb Temperature 68 to 77 Degree Fahrenheit

The trick is there is usually a range of temperatures, not one temperature 40 55% RH at Air Inlet

Its all about the Delta T (^T) 30 Ton Units are Not Really 30 Ton Units. Its 30 Tons at some operating

conditions Examples A 30 Ton nominal,downflow, chilled water CRAC unit may have a sensible

capacity of 27 Tons at 72 degrees, but only 23 Tons when operated at 68 degrees. 18% more capacity at the higher operating temperature!

Capturing return air at a higher temperature allows for a higher Delta T and increase performance.

88 degrees entering the CRAC will produce 30 Tons. A 30% improvement!

Industry Findings and Trends Increasing Chiller Temperature Yields Significant Savings

Normally, for centrifugal compressor-based chillers, an increase of one

degree in the chilled water supply temperature can increase the

operational efficiency of the chiller by 1 to 2 percent. If a chiller can

supply chilled water at 55F, it will be approximately 15 to 30 percent

more efficient than when it produces chilled water at 40F (cooler).

Problems In The Data Center Legacy Designs or Lack Thereof Conventional Designs that did not Anticipate Shifts in

Technology On-Going Changes That Effect The Dynamics Of The Data

Center 24X7X365 Uptime Lack Of Funding - On-Going Capital & Operational Expenses

Doing More With Less Perceived and Real Risks Usually Number One Problem from an Immediate Need:

Heat and Power ( I have enough cooling, but I still have heat problems and we are running out of power.)



Current State of Most Data Centers Regarding Air Flow Management Over Provisioned Air Cooling Adding To Cost

Yet Cooling Is Still A Problem 90% Of Data Center Have Enough or Too Much Cooling 60% Of The Cool Air Is Wasted Due To:

Air Mixing Air Stratification Bypass Air

Why Chaos Cooling in a Data Center? Legacy cooling designs employ an open supply and

return air methodology that drives mixing of both supply and return air streams

Cool air in a legacy data center is used for many purposes

Cool IT equipment Keep warm air away from IT inlets Move warm air toward the return system

Minor changes in any element of the data center create unpredictable behavior which decreases reliability



How Does Chaos Manifest Itself in the Data Center?

Recirculation of air from IT equipment exhaust finds its way to IT inlet and can reduce server performance and even cause servers to stop working

Air stratification is the layering of different temperature air masses and forces set points of precision cooling equipment to be lower than recommended

Bypass Air is the remixing of cool supply air that directly enters the return air stream and drives down precision cooling efficiencies

To prevent processing impact, data centers produce significantly more cold air than is required for IT

devices



Recirculation Hot air exhaust circulating

back into its own intake can cause device thermal overload.

Typical manufacturer inlet temperature threshold for device operations is 95F.

Exceeding manufacturersoperating device threshold can lead to unplanned computing system outages and data loss.



Temperature Stratification Significant gradient of air

temperatures beyond ASHRAE TC9.9 places devices at risk of thermal overload

Maintaining inlet temperature gradients within the ASHRAE recommended range significantly saves energy

ASHRAE TC9.9Manufacturer Specification

Device Inlet Temperature Range (64.4 - 80.6)F (50 - 95)F



Re-Mixing Air Streams Bypass Airflow Jet stream of high-velocity

air has enough momentum to completely bypass the front of the IT rack which creates bypass airflow

Significant efficiencies and cost savings can be realized by eliminating bypass airflow.



Converting Chaos into Order Four Types of Solutions Can Be Employed

Rack-based Heat Containment Cold Aisle Containment Hot Aisle Containment Independent Containment

Two phases exist for each type Partial Containment Total Containment

Two methods for implementation exist Integrated to the Rack Independent to the Rack

A variety of site-based constraints and consumer preferences can drive the best selection

What is Rack-based Heat Containment Stage 1- A Chimney structure that

mounts directly to a top rear of IT Rack Allows hot air to rise directly to high stratification layers

Stage 2 - Connects the exhaust air directly back to the Return Air path of typical air conditioning systems

Can be passive or may be an activeconfiguration with implementation of fans in the chimney

Active control of fans based on temperature or pressure

Overhead Flexibility



Heat Containment - Wright Line and 3rd Party Enclosures Addressing Flexibility and Investment Protection

- Maximize Existing Infrastructure Investments

- Minimize Disruptions- As your applications grow or you

consolidate servers, cooling capacity can be increased simply by modifying the doors, side panels and tops of your enclosure system. The base enclosure remains the same, lowering your Total Cost of Ownership (TCO).



Paramount Tower of Cool

For applications where a full HCS deployment is unnecessary, the patented Tower of Cool, which utilizes High Delta Temperature Cooling (HDTC), can be a perfect alternative. The Tower of Cool efficiently cools 10kW of equipment within 44U, by incorporating the building air conditioning system and the enclosure into one closed-loop cooling system. The Tower of Cool is also the perfect solution for providing supplemental spot cooling in legacy data centers.

By preventing stratified air from entering the top of the enclosure, the Tower of Cool distributes cold air which allows equipment to run at lower temperatures, resulting in increased hardware reliability.

The Tower of Cool, using specialized doors and fans, captures cold air from the raised floor plenum and distributes it throughout the rack.



Airflow Manager for Switches and Routers

Features- Helps eliminate overheating of network racks and other nearby equipment by allowing front to rear airflow through the switch or router

- Improves efficiency by preventing hot exhaust air from mixing with cold intake air.

- Allows the switch or router assembly to be mounted facing the front or rear of the enclosure.

- Resolves the difficult issue of how to mount a switch or Router with unique airflow requirements


Cold and Hot Aisle ContainmentCold and Hot Aisle Containment



What is Cold Aisle Containment? Stage I Partial Containment:

Typically configured with a set of End of Row Doors and the installation of Blanking Panels in all open IT U space

Stage 2 Total Containment: Incorporates the Aisle Ceiling structure which spans the aisle

from the front of one row of racks to the front of the opposing row of racks

Why Implement Cold Aisle Containment? Save Energy Reduce your cold air supply in an open

environment with reduction or elimination of hot and cold air mixing

Provide Predictability By reducing or eliminating re-mixing of hot and cold air in a dynamic data center environment



Cold Aisle Containment Challenges The temperature in the remainder of the data center may

become too hot for optimal employee productivity The local Authority Having Jurisdiction (AHJ) may interpret

total containment as a room within a room which may present additional challenges:

Fire Detection and Fire Suppression Systems

Reduction in thermal inertia for outage ride-through The clear ceilings that are utilized in the contained row may

present some cleaning issues



Why Implement Hot Aisle Containment? All energy used to move/produce cool air is used to cool IT equipment Air conditioner set points can be tuned to deliver ideal inlet air temp to IT

equipment and eliminate the energy from overcooling Warm air is sent directly back to conditioning systems increasing overall

cooling performance Predictable air management is obtained

Stage 1 Partial Containment: Configured with a set of End of Row Doors driving heat upwards

to the preferred stratification layer Stage 2 Total Containment

Incorporates the Aisle Ceiling structure which spans the aisle and allows for return chimney installation

What is Independent Hot Aisle Containment?



Hot Aisle Containment Challenges The temperature in the hot aisle could become too hot for

optimal employee productivity The local Authority Having Jurisdiction (AHJ) may interpret

total containment as a room within a room which may present additional challenges:

Fire Detection and Fire Suppression Systems With ceiling space consumed with exhaust chimneys,

lighting in the rows can become an issue.
