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 the Oracle I/O blade
servers are not managed by an SP, the I/O blade server 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
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 rackmounted chassis
or blade chassis are hot-pluggable, refer to the Oracle server or
CMM hardware 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. |
