ThermalProf ile

•Allows to specify the Thermal Base Algorithm.

•Allows to set the system profile as required for thermal behavior associated to the profile.

Values:

•0 — Auto

•1 — Maximum performance

•2 — Minimum Power

To view the existing thermal profile setting:

racadm get system.thermalsettings.Ther malProfile

To set the thermal profile to Maximum Performance:

racadm set system.thermalsettings.Ther malProfile 1

Modifying Thermal Settings Using iDRAC Settings Utility

To modify the thermal settings:

1.In the iDRAC Settings utility, go to Thermal. The iDRAC Settings Thermal page is displayed.

2.Specify the following:

•Thermal Profile

•Maximum Exhaust Temperature Limit

•Fan Speed Offset

•Minimum Fan Speed

For information about the fields, see the Modifying Thermal Settings Using Web Interface.

The settings are persistent, which means that once they are set and applied, they do not automatically change to the default setting during system reboot, power cycling, iDRAC, or BIOS updates. A few Dell servers may or may not support some or all of these custom user cooling options. If the options are not supported, they are not displayed or you cannot provide a custom value.

3.Click Back, click Finish, and then click Yes.
