Data Center Design and Operations
Fault tolerant means the facility can continue operating through an individual equipment failure or distribution-path interruption. It is associated with Tier IV, but real fault tolerance depends on detailed topology, controls, and isolation.
Municipal utility is owned by a city or local government. It may offer local responsiveness and different governance, but large-load service can still depend on wholesale power supply, transmission access, and regional grid constraints.
Read definition →Economization uses favorable outdoor conditions to reduce mechanical cooling energy. The practical value depends on climate, air quality, humidity, water strategy, controls, and whether the system uses air-side, water-side, or refrigerant methods.
Read definition →Direct-to-chip cooling uses cold plates attached to processors or accelerators, with coolant loops carrying heat away from the chips. It can support high-density racks but adds facility-water, leak-management, redundancy, and serviceability considerations.
