HP ProLiant 300-series AMD-based G6 server technology

Power and thermal technologies

HP engineers have developed a robust set of power and thermal technologies and components to

manage power within ProLiant 300-series G6 servers. The following technologies improve power

efficiency throughout the power delivery chain:

• Efficient power delivery

• Thermal sensors and fan control

• Dynamic Power Capping

• Processor Management technologies

Administrators can disable certain components and capabilities within ProLiant 300-series G6 servers

or reduce capabilities to bring the components to a lower power state.

Efficient power delivery

Oversized and lightly loaded power supplies do not run as efficiently as those that are heavily

loaded. ProLiant G6 servers use common-slot, ”right-size” power supplies and highly efficient DC

power regulators to deliver significantly higher power efficiencies than previous ProLiant servers.

Common-slot power supplies

The HP G6

common slot power strategy provides power supply commonality across ProLiant G6

server lines. HP reduced the number of power supply designs, which reduces the number of spares

that customers must keep in the data center.

By using “right-sized” power supplies, customers can closely meet power needs and avoid

oversubscribing power requirements.

HP “right-sized” power supplies have achieved efficiency ratings

of up to 92%. With the exception of the 1200W power supplies, they meet Climate Savers Gold

requirements. The 1200W and 1200W 48VDC power supplies meet Climate Savers Silver

requirements.

• 460W AC up to 92% efficiency

• 750W AC up to 92% efficiency

• 1200W AC up to 90% efficiency

• 48Vdc 1200W up to 90% efficiency

The power loading efficiency curve for the 750 W power supply shown in Figure 4 illustrates the high

levels of power efficiency achieved by power supplies used in ProLiant G6 servers.
