DellDell PowerEdge M610x 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 Dell™ PowerEdge™M610x achieves higher power efficiency by implementing the following features:• User-configurable power options through the M1000e Chassis Management Controller (CMC)(see the M1000e documentation online at Support.Dell.com for further details)• Improved power budgeting• Voltage Regulator (VR) efficiency improvements• CPU VR dynamic phase shedding• Switching regulators instead of linear regulators• Closed loop thermal throttling• Use of DDR3 memory (lower voltage compared to DDR2)• Memory VR static phase shedding• BIOS Power/Performance options page• Active Power Controller (BIOS-based CPU P-state manager)• Ability to throttle memory• Ability to disable a CPU core• Ability to turn off embedded NICs or PCIe lanes when not being used• Energy Smart components at the M1000e chassis level to selectively enable more computingperformance with less power consumption.5.3 Thermal Operating and Storage SpecificationsThe M610x thermal solution includes: Optimized airflow impedance for individual blade and chassis level airflow balancing Custom air baffling directs airflow through the components to maintain proper cooling Custom designed heat sinks maintain CPU, DIMM, and board-level chip temperatures withinthermal design targets Separate airflow cooling path for the two full-length x16 PCIe Gen2 slots. Support for dual slot NVIDIA® GPU cards up to 250 W. Highly Optimized Fan Control Algorithmo Base fan speeds are a function of hardware configuration and ambient temperature tominimize airflow for a given environment.o Component algorithms: CPU PID, DIMMs, HW Configuration, IOH, GPU, and ExternalAmbient.o The highest fan speed request from the above algorithms is used to set theappropriate fan speed for the blade.o Ambient and HW Configuration sets the minimum; other algorithms increase fan speedto maintain proper cooling.
