Energy efficiency
The x3690 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, 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 IBM 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.
