VERTIV™ SMARTAISLE™
Reduce energy consumption while supporting higher density for IT and networking equipment - without compromising your requirement for availability.
Data Center Efficiency Management Platform
Raised floor data center with perimeter cooling (Liebert PDX/PCW)
Slab floor data center with Liebert CRVrow-based cooling
Vertiv™ SmartAisle™ is a platform of technologies designed to optimize the efficiency, design and operation of your data center infrastructure.
The Vertiv SmartAisle principle is based on the separation of cold and warm zones, and incorporates special cooling capacity and airflow management, raised floor sealing, cable entry sealing and cabinet sealing with blanking panels.
But it is not just physical separation and sealing of the cold and warm zones that makes this system the most efficient. Knürr CoolFlex® solution together with Liebert® PDX/PCW or Liebert CRV units with sophisticated software developed for cold aisle containment is the best way how to enhance the flexibility, reliability and efficiency of your data center.
The control strategy is based on the main task: to provide such cooling capacity that is actually required by IT equipment.
Therefore Vertiv precision cooling units for SmartAisle maintain the Temperature, Humidity and Airflow within the cold aisle containment.
Vertiv SmartAisle™ Is Ideally Suited For:yy Hot/cold aisle architecture
yy Raised floor data centers with perimeter cooling
yy Non-raised floor data centers using row-based precision cooling systems such as Liebert® CRV+ Knürr CoolLoop
yy Retrofit to existing racks.

VERTIV™ SMARTAISLE™
Vertiv™ SmartAisle™ Application Scenarios: Examples Of Data Center Rooms
The traditional approach considers open aisle architecture with the return air temperature to cooling units between 24-26ºC having a supply air temperature between 10-14ºC from the CRAC units. The heat load per rack is in the range of 3 to 5kW/rack.
Row-based cooling units can also satisfy higher heat load density but for large
data centers the space taken for the cooling units placed in the row of racks make this solution questionable. To cope with such issues, Liebert® has in fact developed Liebert® XD which has a zero floor space occupancy in combination with the perimeter cooling. For small and medium data center the in the row cooling is a preferable choice; the cooling units can be direct expansion or chilled
water if the building is designed to handle water pipes, chiller and water containment systems. Usually the best choice is to use direct expansion cooling units in the small and medium capacity data centers while using Chilled water in the large ones.
Chilled water systems deliver high energy efficiency when the chillers are equipped with Freecoolingand are integrated with cooling units.

Using Vertiv SmartAisle solution most of the Traditional Approach limitations can be significantly improved.
Vertiv SmartAisle solution increases space efficiency with heat load limit up to 12 kW/rack with Liebert® PDX/PCW units and up to 20 kW/rack with Liebert CRV cooling units. Vertiv SmartAisle provides
always uniform and predictable temperature to all IT equipment controlling directly Cold Aisle temperature and humidity.
Optimized cooling system efficiency is achieved by optimising the return air temperature without compromising reliability.
In combination with free cooling chilled water system it can provide up to 50%+ efficiency increase and consequently fast return of investment (ROI). Vertiv SmartAisle allows easy retrofit and low initial investment as it fits existing Knürr racks.
