Enclosure Dynamic Power Cap commands
SET ENCLOSURE POWER_CAP
•
Command:
SET ENCLOSURE POWER_CAP { <cap> [<derated_circuit_capacity>
<rated_circuit_capacity>] | OFF }
•
Description:
Sets the Enclosure Dynamic Power Cap in watts AC. OFF disables the Enclosure Dynamic Power Cap.
Average power cannot exceed cap or derated_circuit_capacity. Peak power cannot exceed
rated_circuit_capacity. For example, suppose the PDU powering the enclosure has a rated capacity of
30 amps. In North America and Japan, the standard de-rating ratio is 80%, so the PDU has a derated
capacity of 24 amps (0.80 * 30). At 208 volts, the Rated Circuit Capacity would be entered as 6240
watts (30 * 208), and the Derated Circuit Capacity would be entered as 4992 watts (24 * 208). When
specifying only cap, the other values are calculated using the standard de-rating ratio for North
America. Therefore derated_circuit_capacity is equal to cap and rated_circuit_capacity is equal to
1.25 * cap. The Enclosure Dynamic Power Cap and Derated Circuit Capacity can be specified as any
value in the allowable range. The Derated Circuit Capacity must be at least as large as the Enclosure
Dynamic Power Cap and no larger than the Rated Circuit Capacity. The Enclosure Dynamic Power Cap
can be used to limit enclosure power consumption based on a cooling constraint that might be lower
than the Derated Circuit Capacity.
•
Access level/Bay level:
OA administrator, OA operator
•
Restrictions:
o
A redundant Onboard Administrator is required.
o
The Power Cap must be in the range displayed by the command SHOW ENCLOSURE POWER_CAP.
o
In scripts, if both SET POWER LIMIT and SET ENCLOSURE POWER_CAP are set to non-zero values,
whichever command is used last takes precedence.
SET ENCLOSURE
POWER_CAP_BAYS_TO_EXCLUDE
•
Command:
SET ENCLOSURE POWER_CAP_BAYS_TO_EXCLUDE [NONE | <bay number> {[ , | - ] <bay
number>}]
•
Description:
Specifies bays to omit from Enclosure Dynamic Power Cap. Blades in omitted bays are treated as
unmanaged components of the system: They receive a maximum power allocation even when the
power is not being consumed, raising the minimum Enclosure Dynamic Power Cap value that can be
applied to the enclosure. Any blades in bays not specified are managed.
