Power management technology
The HP DL585 G5 includes HP Power Regulator, an innovative OS-independent power management
tool. HP Power Regulator is a ROM-based utility that can be used to set the server to one of four
power modes:
• Static high power – Server runs continuously in the highest performance state.
• Static low power – Server runs continuously in the lowest power state.
• OS Control – Server uses AMD Opteron PowerNow!™ Technology that allows the operating system
or drivers to control processor power states.
• Dynamic power savings (new with the DL585 G5) – server processor power is automatically
adjusted according to application activity.
HP Power Regulator improves the energy efficiency of the DL585 G5 by allowing the Opteron
processors to run at full power when they need it and enabling power savings without performance
degradation when application activity is reduced. HP Power Regulator modes can be selected
through the ROM-based Setup Utility during POST, or through the iLO 2 remote management interface
anytime during runtime.
