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:

Base fan speeds are a function of hardware configuration and ambient temperature to

—

minimize airflow for a given environment

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

—

margin

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.

Power 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 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
