Energy efficiency
The x3650 M4 HD offers the following energy-efficiency features to save energy, reduce operational
costs, increase energy availability, and contribute to a green environment:
Energy-efficient system board components help lower operational costs.
There are highly efficient 550 W, 750 W, and 900 W AC power supplies with 80 PLUS Platinum
certification. A 750W DC power option is available.
The Intel Xeon processor E5-2600 v2 product family offers better performance over the previous
generation 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 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.
SSDs use as much as 80% less power than traditional 2.5-inch HDDs.
The server uses hexagonal ventilation holes, which are 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.
