A closer look at this 1.1MW data center layout shows the new compressorized Liebert ® DSE™ with
EconoPhase™ pumped refrigerant economizer along with other key enhancements to bring about a highly efficiency facility. Here the designer chose a perimeter gallery to house the cooling and PDU systems
(though 2 or 3-sided are options). We maintained the 36” raised floor for simplified comparison. The 90 racks are hot aisle - cold aisle with partial containment. The ceiling plenum serves to improve airflow as a return-air pathway.

The SmartDesign approach helps data centers save money while still ensuring mission-critical availability. Using the innovative equipment and industry-best practices that this approach offers, you can avoid the costly expenses associated with system failures and down times.
Did you know?
Average data centers experience 5.12 power outages every two years
Outage duration averages 106 minutes
System recovery is estimated at 3 times the duration of the outage (318 on average)
This means that on average, each unplanned outage costs $507,000*.
*Read the Ponemon white paper on costs of downtime at www.EmersonNetworkPower.com
Reduce or eliminate downtime costs of $507,000/event.
With Emerson Network Power and the SmartDesign approach, there’s virtually no limit to what you can solve and how you can design the optimal data center.
For more examples of the high-efficiency and highcapacity data centers that the SmartDesign approach can create, maintain and grow, visit our website.
