will not exceed Rated Circuit Capacity.
When configuring these parameters, the Derated Circuit
Capacity must be at least as large as the Dynamic Power
Cap and no larger than the Rated Circuit Capacity.
The Dynamic Power Cap is used to limit the enclosure power
consumption based on a cooling constraint that might be
lower than the Derated Circuit Capacity. The Derated Circuit
Capacity is used to limit the enclosure average power
consumption on a circuit. The Rated Circuit Capacity is used
to limit the enclosure peak power consumption on a circuit.
If you need to restrict an enclosure electrical load and
thermal output, an Enclosure Dynamic Power Cap is better
than a Static Power Limit. Enclosure Dynamic Power Cap
enables more blades to power on than a Static Power Limit.
For a complete list of BladeSystem server blades supported
by Enclosure Dynamic Power Capping, see the HP website
(http://www.hp.com/go/dpc).
Static Power Limit Power Limit An optional setting to limit power. Whenever you attempt to
power on a device, the total power demands of the new
device and of the devices already on are compared against
this Static Power Limit. If the total power demands exceed the
limit, the new device is prevented from powering on.
A Static Power Limit is better when:
• You do not want caps dynamically adjusted on your
blades.
• You prefer to not power on a server blade if it cannot be
allocated full power (even if it typically consumes less).
• More than 1/4 of the blades in the enclosure do not meet
hardware or firmware requirements for the Enclosure
Dynamic Power Cap.
None None The enclosure power usage is not managed or capped.
