Support for 1.35 V low-voltage DDR3 memory DIMMs that consume 20% less energy.



Energy-efficient components, including low-voltage transistors and voltage regulator modules, and



power supplies that are up to 90% efficient.

Available 675 W high-efficiency power supply with 90%+ efficiency.



The server uses hexagonal ventilation holes in the chassis. Hexagonal holes can be grouped more



densely than round holes, providing more efficient airflow through the system chassis. This ultimately

results in reduced operational costs.

An altimeter works in conjunction with the IMM to govern fan rotation based on the readings that it



delivers. This saves money under normal conditions because the fans do not have to spin at high

speed.
