Availability Predictable cooling Placing the unit in the row of racks moves the source of cooling closer to the heat load. This eliminates air mixing and provides a predictable cooling architecture. Rack Inlet Temperature Control Reduces the risk of hot spots at the rack level Active response controls Monitors and actively adjusts cooling capacity to ensure proper server inlet temperatures. Through the microprocessor controller, visibility into the operation and health of the unit is provided. Total Cost of Ownership Variable speed fans Variable speed fans reduce energy consumption during off-peak cooling periods. In-Row architecture Captures hot exhaust air directly from the IT equipment, thereby increasing the unit's sensible cooling capacity over traditional cooling architectures.
