Configuring power supply options using iDRAC settings
utility
To configure the power supply options:
1. In iDRAC Settings utility, go to Power Configuration.
NOTE: The Power Configuration link is available only if the server power supply unit supports power monitoring.
The iDRAC Settings Power Configuration page is displayed.
2. Under Power Supply Options:
• Enable or disable power supply redundancy.
• Enable or disable hot spare.
• Set the primary power supply unit.
• Enable or disable power factor correction. For more information about the options, see the iDRAC Settings Utility Online Help.
3. Click Back, click Finish, and then click Yes.
The power supply options are configured.
Enabling or disabling power button
To enable or disable the power button on the managed system:
1. In iDRAC Settings utility, go to Front Panel Security.
The iDRAC Settings Front Panel Security page is displayed.
2. Select Enabled to enable the power button or Disabled to disable it.
3. Click Back, click Finish, and then click Yes.
The settings are saved.
Multi-Vector Cooling
Multi-Vector Cooling implements multi-prong approach to Thermal Controls in Dell EMC Server Platforms. You can configure multi-vector
cooling options through iDRAC web interface by navigating to Configuration > System Settings > Hardware Settings > Fan
Configuration. It includes (but not limited to):
• Large set of sensors (thermal, power, inventory etc.) that allows accurate interpretation of real-time system thermal state at various
locations within the server. It displays only a small subset of sensors that are relevant to users need based on the configuration.
• Intelligent and adaptive closed loop control algorithm optimizes fan response to maintain component temperatures. It also conserves
fan power, airflow consumption, and acoustics.
• Using fan zone mapping, cooling can be initiated for the components when it requires. Thus, it results maximum performance without
compromising the efficiency of power utilization.
• Accurate representation of slot by slot PCIe airflow in terms of LFM metric (Linear Feet per Minute - an accepted industry standard
on how PCIe card airflow requirement is specified). Display of this metric in various iDRAC interfaces allows user to:
1. know the maximum LFM capability of each slot within the server.
2. know what approach is being taken for PCIe cooling for each slot (airflow controlled, temperature controlled).
3. know the minimum LFM being delivered to a slot, if the card is a 3rd Party Card (user defined custom card).
4. dial in custom minimum LFM value for the 3rd Party Card allowing more accurate definition of the card cooling needs for which the
user is better aware of through their custom card specification.
• Displays real-time system airflow metric (CFM, cubic feet per minute) in various iDRAC interfaces to the user to enable datacenter
airflow balancing based on aggregation of per server CFM consumption.
• Allows custom thermal settings like Thermal Profiles (Maximum Performance vs. Maximum Performance per Watt, Sound Cap),
custom fan speed options (minimum fan speed, fan speed offsets) and custom Exhaust Temperature settings.
1. Most of these settings allow additional cooling over the baseline cooling generated by thermal algorithms and do not allow fan
speeds to go below system cooling requirements.
NOTE:
One exception to above statement is for fan speeds that are added for 3rd Party PCIe cards. The thermal
algorithm provision airflow for 3rd party cards may be more or less than the actual card cooling needs and
customer may fine tune the response for the card by entering the LFM corresponding to the 3rd Party Card.
2. Custom Exhaust Temperature option limits exhaust temperature to customer desired settings.
