Power capping 48
After a zone mapping has been completed, they can be saved to the SL-APM onboard EEPROM with the
SAVE ZONES command. This action makes the zone definitions persistent across SL-APM resets. It will be
automatically reloaded on reboot. If SAVE ZONES is not used, the zone data will be lost if the SL-APM is reset.
If a zone needs to be deleted, the REMOVE ZONE ALL command can be used. This causes
all ports to be removed from the zone definition and then delete the zone itself. As with all zone mapping
modifications, to make it persistent across SL-APM resets, enter SAVE ZONES.
Power capping with zones
If zones are defined as described above (and assuming a power baseline has been established for the rack),
then the SET POWER CAP command can accept a zone name as a parameter after the wattage value (or
NONE if a power cap is being removed).
For example:
> show zones
Zone BLUE:
Power Manager port 1:
Dist. Module port 2
Dist. Module port 3
Zone GREEN:
Power Manager port 2:
all Dist. Module ports included
Zone YELLOW:
Power Manager port 3:
Dist. Module port 1
> show power baseline

New cap represents 84 percent of the max cap of eligible entities.
Apply cap (Y/N) ->
The above output sets a power cap only to those chassis that are in the zone defined as BLUE. If all the caps
must be removed from a zone, then SET POWER CAP NONE can be used.
> set power cap none blue
Remove power cap(s)? (Y/N) ->
The above command removes all power cap settings from the SL-APM chassis that is resident in on the
SL-APM port 1 and distribution module ports 2 and 3, or zone blue. Since there is only a single chassis that
matches that description, the operation only affects that one chassis.
If a cap is set using a zone, then the zone is removed, the cap is unaffected. A new zone may be created that
includes some or all of the ports of the former zone and caps set against the new zone as well. Zones are
strictly a defined set of SL enclosures that can be used to specify which machines are being considered for a
cap. They are a vehicle for enabling multiple caps and/or “exclusion” areas to be created within a single
SL-APM domain of enclosures with respect to power capping.
