Faster, more powerful and dense computing hardware generates significant heat and
imposes considerable data center cooling requirements. Traditional computer room air
conditioning (CRAC) cooling methods are proving increasingly cost-ineffective and inefficient.
Studies show that using the volume of room air as a heat exchange medium is
wasteful and allows for substantial mixing of hot and cold air. Further, it limits cabinet/
frame/rack density because it cannot effectively cool high heat density equipment that
is spaced closely together.
