Video explanation
A French explainer moves through the building, rack, cooling loop and electrical chain, connecting electricity, computation and heat removal.
Computation produces heat
Most electrical energy consumed by servers ultimately becomes heat that must be removed continuously.
Cooling moves heat
Coolant carries heat from components to exchangers and other loops or the environment. Flow needs depend on temperature rise and heat load.
Power continuity
UPS and backup power bridge interruptions. The power and water figures are article examples, not universal datacenter values.
