SmartAire®
Efficiently Manage Diverse & Variable Loads
|
Tate’s SmartAire® electronically controlled variable air volume damper used in conjunction with DirectAire® adjusts the amount of air to meet the specific needs of the rack it services. Both the SmartAire® S & M use sensors mounted to the front of the rack to control the VAV damper ensuring the proper inlet air temperature is maintained on a rack-by-rack basis. The SmartAire® C uses information collected from the existing client sensor network to control the damper. This flexibility can help effectively cool facilities implementing virtualization, cloud computing and idle server shutdown strategies while saving energy.

Understanding & Managing Diverse & Variable Loads
Each rack in the data center is a constantly changing due to the processing demands of the IT hardware at a given time. This load variability has been driven by IT hardware that has become more efficient over time, increasing the difference between idle power consumption and 100% utilization. This fact, coupled with the increasing use of cloud computing, will only serve to drive increased load variability in the rack on a minute by minute basis, making manual tuning of the airflow at the panel level impossible.
SmartAire® Effectively Solves the Problem
The solution has been to provide sufficient air to accommodate the peak energy demands of the rack, resulting in wasted bypass air and over-cooling during all less than peak conditions. SmartAire® measures the incoming air temperatures at the face of the rack and adjusts the VAV damper to control the air flow and ensure that the temperature at the face of the rack is never above the maximum allowable set point provided by the user. When deployed using best practices, the system is able to virtually eliminate bypass air, and account for any local temperature fluctuations.
The chart above shows how SmartAire® saves energy by directly matching cooling to the variability in the energy consumed for the IT load at the rack level for a cloud cluster.
