Dell PowerEdge M710 Technical Guide 165 Power, Thermal, Acoustic5.1 Power SuppliesSee the PowerEdge M1000e Technical Guide for information on power supplies and power supplyspecifications.5.2 Power EfficiencyOne of the main features of blade servers is enhanced power efficiency. The PowerEdge™ M710achieves higher power efficiency by implementing the following features: User-configurable power options through the M1000e Chassis Management Controller (CMC)(see M1000e documentation on Support.Dell.com for further details) Improved power budgeting Voltage Regulator (VR) efficiency improvements Processor VR dynamic phase shedding Switching regulators instead of linear regulators Closed loop thermal throttling DDR3 and LV-DDR3 memory Memory VR static phase shedding BIOS Power/Performance options page Active Power Controller (BIOS-based processor P-state manager) Ability to power down or throttle memory Ability to disable a processor core Ability to turn off embedded NICs or PCIe lanes when not being used Option to run PCIe at Gen1 speeds instead of Gen2 Energy Smart components at the M1000e chassis level to selectively enable more computingperformance with less power consumption.5.3 Thermal Operating and Storage SpecificationsThermal specifications for the PowerEdge M710 are detailed in Table 3 along with other importantoperating and storage information.Table 3.
