Owner's Manual

• Average: The average value from the previous time point to the current time point.

• Maximum: The maximum value from the previous time point to the current time point.

• Minimum: The minimum value from the previous time point to the current time point.

For example, you view power details in the 1H (1 hour) window and the maximum value at 15:00 shows 500W and the

time interval is 6 minutes. This value would represent that the maximum power consumption from 14:54 to 15:00 is 500W.

NOTE: It is common to see some instantaneous values exceed the Power Cap value in the Maximum line. Power

Center monitors this value and controls it to the normal power range with this happens. You only need to pay

attention when the Average power value exceeds the Power Cap value.

NOTE: You can set the time interval (the period from a time point to the next time point) in the Settings page. For

information on configuring the interval, see Monitoring Settings.

Power Details for Racks

For racks, you can click Power Consumption to display PDU power consumption for all rack PDUs.

You can also click Power Policies to change a power policy.

NOTE: The Power Policies button is only enabled if you have configured a power policy in the Policies page.

You can view the following power details of PDU devices. For more information on supported PDU devices, see System

Requirements.

• PDU device information, including PDU name, model, and IP address.

• PDU outlet information, including outlet number, power (W), voltage (V), amps (A), and the time of the

information recorded, following the format <YYYY-MM-DD HH:MM:SS>. The table lists the information for each

outlet and the total power consumption for all outlets.

NOTE: For PDU outlet information, Power Center only supports the Dell Managed Rack PDU 6605.

Viewing Energy Consumption

Details of each device and device group power consumption are available on all tabs of the Devices screen.

• IT Equipment Energy — The total energy consumption and cost for all managed devices in the selected device/

group.

NOTE: Power Center can read the power consumption of a device when it as at S0 (On) state. For devices in S4/S5

state, Power Center uses a fixed value (30W) to calculate the power consumption.

• Cooling Energy — The estimated energy consumption and cost needed to cool the selected device/group.

Cooling Energy = IT Equipment Energy * Cooling Multiplier

You can configure the cooling multiplier on the Settings → General screen, in the Energy Consumption section.

• Energy Consumed (Total) — The combined energy consumption and costs for the IT equipment and cooling

energy. The formula is:

Cost = (IT Equipment Energy T1*Cooling Multiplier) *Flat Rate T1+(IT Equipment Energy T2*Cooling Multiplier)

*Flat Rate T2+°¦+(IT Equipment Energy Tn*Cooling Multiplier) *Flat Rate Tn

NOTE: T1/T2/.../Tn is the time period (in hours) at a certain flat rate.
