Considerações de Design do Data Center

Which two statements concerning heating and cooling design are correct?

Choose two
  • A All devices in a rack should be installed so that the port panels are on the same regardless of the air flow direction.
  • B All devices in a rack should be installed so that the air flow is in the same direction regardless of the port panel location.
  • C In the hot-aisle/cold-aisle design, air enters through vents in the hot-aisle and exists through cold-aisle vents.
  • D The hot-aisle/cold-aisle design maximizes the cooling potential of the air conditioning system.
Explanation

Equipment should be installed so that its airflow is consistently directed from the cold aisle to the hot aisle, irrespective of port-panel location. Hot-aisle/cold-aisle layouts separate supply and exhaust air: cooled air enters equipment from the cold aisle and heated air is exhausted into the hot aisle. This separation reduces hot-and-cold air mixing and makes more effective use of the cooling system’s capacity.
