The sliding door low profile aisle containment system shall create a structure including end of row doors and ceiling panels that enclose the cold aisle between rows of cabinets to segregate cold and hot air streams to and from equipment. This passive system shall contain no moving parts. Designed to ontain the cold air, the system shall be deployed on raised floors. The system shall leverage existing data center cooling and equipment fans to move the flow of exhaust air and cooling air. The system shall address heat loads up to 20kW per cabinet to enable dense server applications and eliminate data center hot spots versus conventional raised floor cooling systems that manage heat loads up to 7-8kW/cabinet. The modular system shall be capable of being added without disrupting existing in-cabinet equipment and cabling to enable a migration path.
