Proposed herein are techniques that combine hot air containment methods and a Smart Cooling, Ventilation, and Air Conditioning (HVAC) control system in a manner that provides for improvements in facility cooling capabilities and acoustic noise reduction. The techniques presented herein also provide safety improvements for facility personnel, including but not limited to the eliminating and/or minimizing the exposure to hot equipment air and high acoustic noise, as well as the opportunity for significant energy and cost savings with Power Usage Effectiveness (PUE) improvement. The techniques presented herein include features for hot air containment, elimination of cooling of wasted heat air, and improvements to the air-cooling capability for NextGen platforms for line cards, FEP and BMP supplies, and ASICs, while reducing the rack cooling power requirements and raising the platform power efficiency.
