Configuring A Power Cap - HPE Apollo 2000 User Manual

This is the default power capping mode. This mode allows the maximum number of nodes to run by
engaging power-capping if the power draw from the chassis attempts to exceed the load supported
by the active power supplies. In this mode, the system is expected to survive an unexpected power
loss to one of the power supplies.
•
Mode 2: Full AC/DC Redundancy Mode
Power-capping is enforced such that system has N+1 power redundancy. In this mode, the system
should see no performance degradation because of a power supply loss.
•
Mode 3: User Configurable Mode
The user can specify a valid power cap value from a pre-defined range. A cap cannot be set below a
minimum or above a maximum. The cap includes all server nodes, fans, and drives. User
configurable mode requires an iLO Scale Out or iLO Advanced license.
NOTE: Mode 3 is only supported through APM.

Configuring a power cap

To configure power capping, you can use the following utilities:
•
HPE ProLiant Power Interface Control Utility
PPIC is a standalone utility that runs on a single server within the enclosure. For more information,
see the ProLiant Power Interface Control (PPIC) Utility User Guide on the Hewlett Packard
Enterprise website (http://www.hpe.com/support/PPIC_UG_en).
•
Advanced Power Manager
APM is a rack level device that can control power caps for all enclosures in the rack. For more
information, see the Advanced Power Manager User Guide on the Hewlett Packard Enterprise
website (http://www.hpe.com/support/APM_UG_en).
Setting the chassis power cap mode with the PPIC utility
Download and install the ProLiant Power Interface Control Utility from the Hewlett Packard
1.
Enterprise website (http://www.hpe.com/info/hpesc).
Log in to the node, and then run the PPIC utility.
2.
To set the power capacity mode, perform one of the following steps:
3.
To set mode 0, 1, and 2, enter the following command at the prompt:
o
-s -mmode
The following example sets the power capacity to mode 0:
-s -m0
To set mode 3, enter the following command at the prompt:
o
-s -mmode -lpower
The following example sets the power capacity to mode 3 with a 1500W maximum power limit:
-s -m3 -l1500
Power capping modes show the valid values for mode. Power is required when setting Power Control
Configuration to User Configurable.
