PowerEdge R660 Power-saving Features Details
Intelligent Cooling Technology
The server adopts a "multi - vector cooling technology" based on traditional air - cooling. Combined with a unique "T" - shaped motherboard layout, it can effectively direct the air flow to the part of the server with the highest temperature through a dedicated duct - type fan and automatic cooling function, reducing energy consumption. At the same time, it also provides liquid - cooling options, such as cold - plate liquid - cooling and immersion - type liquid - cooling, which can improve overall system efficiency and reduce power consumption.
Processor Power Management
The server supports the dynamic voltage and frequency scaling of the processor. According to the workload, the system can automatically adjust the voltage and frequency of the processor to achieve power saving while meeting the performance requirements. It also has the function of processor or core reduced power states. When the workload is low, the processor core can enter a low - power state to reduce power consumption. In addition, power capping can be set to limit the maximum power consumption of the processor, avoiding unnecessary power waste.
Power - saving BIOS Settings
Users can select CPU power management and energy - efficient policy settings in the system BIOS. For example, enabling the Dynamic Application Power Management (DAPC) function allows the BIOS to manage the processor power state to achieve the maximum performance per watt at all utilization levels.
Fan Speed Control
The server can adjust the fan speed according to power or thermal readings. When the server load is low and the temperature is low, the fan speed will decrease, reducing the power consumption of the fan.
Low - power States of Components
The memory and I/O devices of the Dell PowerEdge R660 can also enter low - power states. When these components are not in use or have a low workload, the system will automatically switch them to a low - power mode to save power.
Energy Monitoring and Management
With the built - in remote access controller iDRAC and the power management plug - in OME Power Manager, users can measure and control energy distribution anytime and anywhere. OME PMP can monitor and manage the power consumption and heat dissipation of individual servers and server groups, and generate CPU performance status and power consumption reports, helping users maintain the balance between performance and workload and achieve energy - saving purposes.
