11G Servers will be the most energy smart
servers that Dell will ship. In addition to P,C
and T states, BIOS will expose the Power
Profiles to the OS. Each Power profile will have
a specific settings and it will fine tune
processor, MCH, IOH and South Bridge. For

Table 16. Power Profiles that R210 BIOS will Expose in BIOS Setup
DBPM Disabled ( BIOS will set P-State to MAX)
Memory frequency = Maximum Performance
Fan algorithm = Maximum Performance
Enable OS DBPM Control (BIOS will expose
all possible P states to OS)
Memory frequency = Maximum Performance
Fan algorithm = Minimum Power
Enable DellSystem DBPM (BIOS will not make all P states
available to OS)
Memory frequency = Maximum Performance
Fan algorithm = Minimum Power
