Energy efficiency
The x3300 M4 server offers the following energy-efficiency features to save energy, reduce operational
costs, increase energy availability, and contribute to the green environment:
Energy-efficient system board components to help lower operational costs.

High-efficient 550 W and 750 W redundant power supplies, with 80 PLUS Platinum certification, and

an efficient 460 W fixed power supply with 80 PLUS Bronze certification.
The Intel Xeon processor E5-2400 product family, which offers better performance over the previous

generation and fits into the same TDP limits.
Intel Intelligent Power Capability, which powers individual processor elements on and off, as needed,

to reduce power draw.
Low-voltage Intel Xeon processors that draw less energy to satisfy demands of power and thermally

constrained data centers and telecommunication environments.
Low-voltage 1.35 V DDR3 memory RDIMMs that use 15% less energy than 1.5 V DDR3 RDIMMs.

Use of hexagonal ventilation holes, which are part of the IBM Calibrated Vectored Cooling™

technology. Hexagonal holes can be grouped more densely than round holes and provide more
efficient airflow through the system.
IBM Systems Director Active Energy Manager™, which provides advanced data center power

notification and management to help achieve lower heat output and reduced cooling needs.
