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 buildso Improved Efficiency of the Cooling Systemo Flexibility to keep data center cool.

Cold Aisle Containment – Retrofit for existing data center o Flexibility to adapt to existing room cooling systemso 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

Product Trade-Offs - Uniflair

UniFlair

Benefitso Flexibility to handle racked and non-racked IT equipmento Easily Deploy in existing raised floor environmentso Integrated redundancy on the electrical sections with double power

supplyo Possibility to optimize the airflow based on the operating conditions

(AFPS)o Low first costo Complete integration with the Uniflair chillers with dynamic optimization

of the operating parameterso Cooling equipment is located on perimeter of the room or in corridors

outside of the data centero Build to order units – configurable to specific customer requirements

Considerations to Implementationo Typically installed with raised floor o Supplemental air distribution and fans systems may be required to

address high densityo Requires space and provisions to connect to heat rejection system

(Chiller, condenser, cooling tower, fluid cooler, ect..) located in mechanical room or outdoors.


Product Trade-Offs - InRow

InRow

Benefitso Predictable airflow patterns as a result of close coupling easily enables

higher densitieso Rack inlet temperature control ensures temperatures to servers are

maintained 7x24x365o Redundancy and capacity sharing between units using Active Response

Controlso Integrated redundancy on the electrical sections with double power

supplyo Integrated cooling module as part of ISX for modular, scalable, and

manageable data centero Independent of a raised flooro Flexibility for floor mount or overhead installation to address facility

constraintso Standardized units typically available in stock for quick delivery

Considerations to Implementationo Cooling equipment adjacent to IT equipment - water or refrigerant in the

rowo Typically requires more cooling units increasing connection points & costo Requires space and provisions to connect to heat rejection system

(Chiller, condenser, cooling tower, fluid cooler, ect.) located in mechanical room or outdoors.


Product Trade-Offs - Chillers

Chillers

Benefitso Complete package solution with integrated free-cooling system and

onboard hydronic moduleo Integrated redundancy on the refrigerant, hydraulic and electrical

sections (integrated ATS, double pump/s…)o Complete integration with the Uniflair units with dynamic optimization

of the operating parameterso Self optimization of all the installed chillerso Build to order units – configurable to specific customer requirementso Containerized cooling module: completely integrated free-cooling

solution in a fully equipped (hydraulical&electrical) container

Considerations to Implementationo Requires clearances around the unit for maintenanceo Low temperatures installations operate with glycol mixtureso Installation and sizing of interconnecting piping, valves, and other

hydronic systems is required.


Product Trade-Offs - EcoBreeze

EcoBreeze

Benefitso Highest efficiency – maximizes free cooling hours in most climateso No additional heat rejection systems required o Located outside of the data center freeing up white spaceo Built in modularity allows scalability of cooling capacity with demand.

Considerations to Implementationo requires space outdoors next to the building or on a roof in close

proximity to the data centero Must accommodate space for supply and return duct systems within

the building to and from the data center


Summary

Schneider-Electric has a complete offer of cooling solutions to address any IT environment from the Network Closet to the Data Center
