Energy efficiency
The HS23E offers the following energy-efficiency features to save energy, reduce operational costs,
increase energy availability, and contribute to the green environment:
The component-sharing design of the BladeCenter chassis provides ultimate power and cooling

savings.
Energy-efficient planar components help lower operational costs.

The Intel Xeon processor E5-2400 product family offers better performance over the previous

generation, while fitting into 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 demands of power and thermally

constrained data centers and telecommunication environments.
Low-voltage 1.35 V DDR3 memory RDIMMs consume 19% less energy than 1.5 V DDR3 RDIMMs.

Solid-state drives (SSDs) consume as much as 80% less power than traditional 2.5-inch HDDs.

The HS23E 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.
IBM Systems Director Active Energy Manager™ provides advanced power management features with

actual real-time energy monitoring, reporting, and capping features.
