5.3 Thermal

The M910 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, IOH, and Intel 7500 chip temperatures within thermal design targets

∙Highly Optimized Fan Control Algorithm such as the following:

o Base fan speeds are a function of hardware configuration and ambient temperature to minimize airflow for a given environment

o PID control algorithms are used for both CPU and DIMMs to maintain appropriate thermal margin

o Double refresh switching allows for DIMM temperature excursions up to 95°C while maintaining performance and thermal design targets as follows:

The M910 thermal algorithm monitors the thermal sensor on each DIMM to maintain DIMM temperatures below the typical 85°C specification in normal operating conditions.

Under extreme operating conditions, the thermal algorithm can switch the DIMMs into Double Refresh mode allowing an additional 10°C of thermal headroom. In Double Refresh mode, DIMMs are allowed to operate as high as 95°C.

5.4Power Efficiency

One of the main features of blade servers is enhanced power efficiency. The PowerEdge M910 achieves higher power efficiency by implementing the following features:

•User-configurable power options via the M1000e Chassis Management Controller (CMC)

•Improved power budgeting

•Voltage Regulator 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 computing performance with less power consumption
