Flex System x240 Compute Node (E5-2600 v2) 4

Energy efficiency

The x240 offers the following energy-efficiency features to save energy, reduce operational costs,

increase energy availability, and contribute to the green environment:

Component-sharing design of the Flex System chassis provides ultimate power and cooling savings.



The Intel Xeon processor E5-2600 v2 product family offers significantly better performance over the



E5-2600 family while fitting into the same thermal design power (TDP) limits.

Intel Intelligent Power Capability powers individual processor elements on and off as needed, to



reduce power draw.

Low-voltage Intel Xeon processors draw less energy to satisfy demands of power and thermally



constrained data centers and telecommunication environments.

Low-voltage 1.35 V DDR3 memory RDIMMs consume 15% less energy than 1.5 V DDR3 RDIMMs.



Solid state drives (SSDs) consume as much as 80% less power than traditional spinning 2.5-inch



HDDs.

The x240 uses hexagonal ventilation holes, a part of IBM Calibrated Vectored Cooling™ technology.



Hexagonal holes can be grouped more densely than round holes, providing more efficient airflow

through the system.
