A. Row-oriented architecture allows cooling capacity to be matched to the heat load within each zone. B. Row-oriented architecture cools all rows of the data center while generating additional conditioned air for the adjacent office areas. C. Row-oriented architecture requires two cooling units per enclosure, creating a desirable oversizing scenario. D. Row-oriented architecture requires large volume of air mixing to reduce the return air temperature, driving up cooling system capacity.
