A look at developments giving new life to traditional perimeter cooling systems

Despite inroads made by newer approaches to data-center cooling, such as close-coupled systems, in recent years, changes to industry standards, improved components, and the industry adoption of energy-efficient air management have allowed perimeter cooling (commonly referred to as computer-room air conditioners [CRACs] or computer-room air handlers [CRAHs]) to maintain its position as the most widely accepted choice for cooling in mission-critical information-technology (IT) environments.
