22 PowerEdge VRTX Technical GuideFeature DescriptionActive power managementIntel Node Manager is an embedded technology that provides individualserver-level power reporting and power limiting functionality. Dell offers acomplete power management solution comprised of Intel Node Manageraccessed through Dell iDRAC7 Enterprise and OpenManage Power Centerthat allows policy-based management of power and thermals at theindividual server, rack and data center level.Hot spare reduces power consumption of redundant power supplies.Thermal control of fan speed optimizes the thermal settings for yourenvironment to reduce fan consumption and lower system powerconsumption.Idle power enables Dell servers to run as efficiently when idle as when at fullworkload.Dell Fresh Air coolingWith the thermal design and reliability of Dell products, certainconfigurations have the capability to operate at excursion-basedtemperatures beyond the industry standard of 35°C (95°F) up to 45°C (113°F)for excursionary periods of time and up to a 26°C dew point at 90% relativehumidity without impacting your availability model.

VRTX uses these PSUs to support both low-line(115 VAC) and high-line (220 VAC) power sources. Dell 1100W PSUs support a maximum of fourPSUs with the current sharing circuitry. The low-line and high-line power capabilities are roughlyequivalent, with only slightly more power available in high-line power sources.VRTX PSUs support three power supply redundant options (1+1, 2+1, or 3+1) or one AC redundancymode (2+2).Due to the strict acoustic requirements for VRTX, it is preferred to always run four PSUs in thesystem for best distribution of the power loading and lowest fan speed for the PSU fans. PSU fansexhibit an exponential increase in noise based upon fan speed.1100W PSU specificationsTable 7.Attribute Value80 Plus Platinum PlusPower factor correction ActiveFCC classification Class A
