Containment Recommendations
 Always use containment for optimal TCO
o Payback is immediate with close coupled cooling
o 3 year ROI for Room Based Cooling improves with density
 Hot Aisle Containment preferred approach for new data center builds
o Improved Efficiency of the Cooling System
o Flexibility to keep data center cool.
 Cold Aisle Containment – Retrofit for existing data center
o Flexibility to adapt to existing room cooling systems
o Active floor to assist with cold air distribution from raised floor to ensure
sufficient air flow is available in contained aisle.
o Efficiency Gains Require elevating room temperature

Built in modularity allows scalability of cooling capacity with demand.
 Considerations to Implementation
EcoBreeze
o requires space outdoors next to the building or on a roof in close
proximity to the data center
o Must accommodate space for supply and return duct systems within
the building to and from the data center
