In order to further reduce the energy consumption of the IT system, consideration must be given to the usual construction guidelines for server rooms (warm/cold aisle encasing and optimised air flow) and if possible, reliance must be placed on open air cooling with fresh air supply (instead of a fully air-conditioned system). | In order to further reduce the energy consumption of the IT system, consideration must be given to the usual construction guidelines for server rooms (warm/cold aisle encasing and optimised air flow) and if possible, reliance must be placed on open air cooling with fresh air supply (instead of a fully air-conditioned system). | ||
