Select Monitors → Fuel Gauge to view the power information, based on projected power consumption, for each power domain of the BladeCenter® unit.
Click the Power management policy settings link to go to the section of the Blade Tasks → Configuration page where you configure power management for the BladeCenter unit (see Configuration for information).
There are two power domains in the BladeCenter unit. Click Power Domain 1 details or Power Domain 2 details for the list of BladeCenter components in each power domain (see detailed power status for information). The power-management policy settings determine how the BladeCenter unit reacts in each power domain to a power-source failure or power-module failure. The combination of the BladeCenter configuration, power-management policy settings, and available power might cause blade servers to reduce their power levels (throttle) or not turn on.
The following power status information is displayed in the BladeCenter Power Summary and BladeCenter Power Planning sections:
- Status: This field contains a color-coded icon that indicates status of the power domains and a short status description that lists any outstanding issues that are related to power consumption or redundancy in each power domain.
- Power Modules: This field lists the power modules that are installed in each power domain and their rated capacity, in watts.
- Power-Management Policy: This field displays the power-management policy that is set for each power domain, defining how the power domain will react to conditions that might result in a loss of redundancy. This setting is configured on the Blade Tasks → Configuration page (see Configuration for information).
- Power in Use: This field displays the current power that is being used in each power domain, in watts.
- Total Power: This field displays the amount of power that is available in each power domain, in watts. Total power is calculated by the management module according to the rated capacities of the power modules that are installed in a power domain and the power-management policy that has been set for the power domain.
- Allocated Power (Max): This field displays the total amount of power, in watts, that is reserved for use by the components that are installed in a power domain. This value might include power for components that are not currently installed in the BladeCenter unit, such as the I/O modules. Power is reserved for these components because the management module preallocates power for some components that are normally required for BladeCenter unit operation. The reserved-power total might also include power for components that are installed in the BladeCenter unit, are in a standby state, and are not turned on. These components are included in the total so that the amount of spare (unallocated) power in the power domain can be accurately calculated.
- Remaining Power: This field displays the amount of unallocated (spare) power in a power domain, in watts. This value is used by the management module when it determines whether a newly installed module should turn on. The remaining power value is calculated according to the total power and the amount of reserved power for each power domain.
