Energy efficiency

The x222 offers the following energy-efficiency features to save energy, reduce operational costs,

increase energy availability, and contribute to a green environment:

The x222 is Energy Star 2.0 compliant. Energy Star is the trusted, US government-backed symbol for



energy efficiency, with the goal of helping customers save money and protect the environment

through energy efficient products and practices. For the Power and Performance Data Sheet, see

The component-sharing design of the Flex System chassis provides ultimate power and cooling



savings.

The Intel Xeon processor E5-2400 product family offers better performance over the previous



generation while fitting in to the same 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 the 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 server 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.
