Energy efficiency

The x3850 X5 offers the following energy-efficiency features to save energy, reduce operational costs,

increase energy availability, and contribute to the green environment:

Energy-efficient planar components help lower operational costs.

Support for one or two or four highly efficient 675 W ac power supplies allows for efficient use and

scalability to meet the power requirements of the installed components.

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

previous generation while fitting into the same thermal design power (TDP) limits.

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 compared to 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, which is a part of Calibrated Vectored Cooling™

technology. Hexagonal holes can be grouped more densely than round holes, providing more

efficient airflow through the system.

IBM Systems Director Active Energy Manager™ provides advanced data center power notification

and management to help achieve lower heat output and reduced cooling needs.
