Oracle rackmounted servers

Power allocated to an Oracle rackmounted server is the maximum power the rackmount chassis components are capable of consuming. This value represents the maximum power wattage consumed by the processors, memory, I/O, fans, as well as the power loss across the power supplies. If the rackmount chassis contains slots for hot-pluggable components, the Power Allocated property value shown represents the maximum power wattage required for the most power-consuming component that can be installed in the hot-pluggable slot.

Oracle blade servers

Power to an Oracle blade server is allocated by the CMM when a request for power is made by the blade server. The blade server requests power whenever it is powered on, and releases power to the CMM whenever it is powered off. The CMM allocates power to the blade server if the grantable power is sufficient to meet the blade server's request. In addition, the CMM will verify whether a Grant Limit is set for the corresponding blade slot. If a Grant Limit is set for the corresponding blade slot, the CMM will allocate power to the blade server only when the power wattage request is less than or equal to the Grant Limit property set for the blade slot.

Oracle auto-powered I/O blades

Since Oracle I/O blade servers are not managed by an SP, I/O blade servers will not seek permission to power-on from the CMM. When an I/O blade server is installed in an Oracle blade chassis, the I/O blade server will automatically power on.

Hot-pluggable chassis components

Oracle ILOM automatically displays a pre-allocated maximum power value for any known hot-pluggable component that is installed in a hot-plug designated chassis slot location.For example:

• For rackmount hot-pluggable slots, Oracle ILOM displays the known maximum power wattage value required for a hot-pluggable component.

• For blade hot-pluggable slots, Oracle ILOM displays the maximum power value required for any Oracle I/O blade server that could be installed in the blade chassis slot. However, if the Oracle blade chassis does not support I/O blade servers, Oracle ILOM displays the maximum power wattage value required for a CPU blade server.

To determine which components or slots in a rackmount chassis or blade chassis are hot-pluggable, refer to the Oracle server or blade chassis documentation.

Chassis component categories

For chassis component categories that include multiple instances of the same component, Oracle ILOM presents the total sum of power allocated for a component category (fans), as well as the total sum of power allocated to an individual component (fan0).

Power supply unit (PSU)

Oracle ILOM automatically allocates power to the power supply to account for power losses between the wall outlet and the managed device.
