Systems management iDRAC9 Enterprise provides system-level management thatmonitors, reports, and controls power consumption at theprocessor, memory and system level. OpenManage Power Centerdelivers group power management at the rack, row, and data centerlevel for servers, power distribution units, and uninterruptible powersupplies.Active power management Intel Node Manager is an embedded technology that providesindividual system-level power reporting and power limitingfunctionality. Dell EMC offers a complete power managementsolution comprised of Intel Node Manager accessed through DellEMC iDRAC9 Enterprise and OpenManage Power Center thatallows policy-based management of power and thermals at theindividual system, rack, and data center level.Hot spare reduces power consumption of redundant powersupplies.Thermal control of fan speed optimizes the thermal settings foryour environment to reduce fan consumption and lower systempower consumption.Idle power enables Dell EMC servers to run as efficiently when idleas when at full workload.Thermal and AcousticsThe system's thermal management delivers high performance through optimized cooling of components at the lowest fan speeds across awide range of ambient temperatures from 10°C to 35°C (50°F to 95°F) and to extended ambient temperature ranges. Theseoptimizations result in lower fan power consumption for lower total system power and data center power consumption.Power supply unitsEnergy Smart power supplies have intelligent features, such as the ability to dynamically optimize efficiency while maintaining availability andredundancy. Also featured are enhanced power-consumption reduction technologies, such as high-efficiency power conversion andadvanced thermal-management techniques, and embedded power-management features including high-accuracy power monitoring.The system supports two hot-swappable AC power supplies with 1 + 1 redundancy, auto-sensing and auto-switching capability.Acoustical designDell EMC focuses on sound quality in addition to sound power level and sound pressure level. Sound quality describes how disturbing orpleasing a sound is interpreted, and Dell EMC references a number of psychacoustical metrics and thresholds in delivering to it. Toneprominence is one such metric. Sound power and sound pressure levels increase with greater populations or higher utilization, while soundquality remains good even as the frequency content changes. A reference for comparison to sound pressure levels for familiar noise sourcesis given in the following table. An extensive description of Dell EMC Enterprise acoustical design and metrics is available in the DellEnterprise Acoustics white paper.Table 16.
