25.1.2.2.1 Power utilization metrics

Power capacity is the calibrated maximum power that a device can consume. Use this data to
determine how much power your facility is consuming and the resources that are consuming it.
The appliance reports Alerts for devices that exceed their power capacity.

Description

Metric

The average amount of power the resource is consuming

Average power

The peak amount of power consumed by the resource

Peak power

Most server hardware and enclosures support control of power consumption through a Dynamic
Power Cap. When reporting power utilization, the appliance includes both average and peak
power consumption as well as Dynamic Power Cap settings in its graphs. The appliance controls
power caps through iLO or enclosure OA.

Description

Resource

The power consumption or cooling limitation on the enclosure.

When you set the Dynamic Power Cap on an enclosure, it keeps
the power used by the enclosure under the cap by managing
the power consumption of server hardware.

To set power limits on an enclosure, select the Power
thermal

→Power management menu item on the enclosure OA.

The Dynamic Power Cap limits the enclosure power consumption
based on a cooling limit that might be lower than the Derated
circuit capacity.

The Average power cannot exceed the Power cap or the Derated
circuit capacity.

The Peak power cannot exceed the Rated circuit capacity.

Enclosures

The limitation on power consumption enforced by the
management processor, in watts.

25.1.2.2.2 Temperature utilization metrics

Temperature utilization graphs display the ambient/inlet air temperature of your data center. The
air temperature is detected by sensors embedded on the front of enclosures and other hardware
devices.

The operating threshold is 10°C to 35°C (50°F to 95°F). When the device reaches a threshold, it
generates temperature alerts. The appliance displays these alerts in the notification banner and in
the Activity sidebar.

NOTE:

The temperature is displayed in degrees Celsius or Fahrenheit, depending upon the locale

setting of your browser.
