Data Center Design and Operations
Tier II adds redundant capacity components but still generally requires shutdowns for some maintenance and has distribution-path exposure. It is a step up from basic capacity but not concurrently maintainable.
Rear Door Heat Exchanger is a heat exchanger mounted on the exhaust side of a rack to remove heat before it enters the room. It can help densify air-cooled or hybrid deployments without fully converting to direct liquid cooling.
Read definition →Liquid cooling removes heat using liquid closer to the IT components than traditional room air cooling. It is increasingly important for AI workloads because rack power densities can exceed practical air-cooling limits.
