38 PowerEdge R730 and R730xd Technical Guide8 Power, thermal and acousticsLower overall system-level power draw is a result of Dell’s breakthrough system design. PowerEdgeservers aim to maximize performance-per-watt through a combination of energy efficienttechnologies, optimized thermal designs and intelligent fan control algorithms. The PowerEdgeR730/R730xd fan control algorithms use an extensive array of sensors that automatically monitorpower and thermal activity to minimize fan speeds based on system cooling requirements, reducingthe power required for cooling.Power consumption and energy efficiencyWith the rise in the cost of energy coupled with increasing data center density, Dell provides toolsand technologies to help you realize greater performance with less energy cost and waste. Moreefficient data center usage can reduce costs by slowing the need for additional data center space.Table 21 lists the tools and technologies Dell offers to help you achieve your data center goals bylowering power consumption and increasing energy efficiency.Table 21.
