HP SIM for NonStop Manageability

4 Monitoring the Power Regulator with HP SIM
You can set up or disable Power Regulator on NonStop BladeSystem NB54000c, NB54000c-cg,
NB56000c, and NB56000c-cg to provide centralized control of server power consumption. First
use the OSM Service Connection to enable Power Regulator as described in “Enable Power
Regulator” (page 28), and then immediately use Insight Control Power Management to set the
Power Regulator as described in “Alter Power Regulator Setting” (page 29). To disable Power
Regulator, use the the OSM Service Connection as described in “Disable Power Regulator”
(page 31).
NOTE: You must have a NonStop BladeSystem NB54000c, NB54000c-cg, NB56000c, or
NB56000c-cg.
About Power Regulator
The Power Regulator feature is available for NonStop BladeSystem NB54000c, and NB54000c-cg
running RVU J06.14 or later and OSM server SPR T0682ACZ or later.
The Power Regulator feature is available for NonStop BladeSystem NB56000c and NB56000c-cg
running RVU J06.16 or later and OSM server SPR T0682ADF or later.
The Power Regulator settings supported for NonStop BladeSystem NB54000c, NB54000c-cg,
NB56000c, and NB56000c-cg are described below. See the Insight Control Power Management
7.1 User Guide for more information about Power Regulator.
DescriptionHP Power Regulator Setting
In Static High Performance Mode, the CPU
1
runs at the maximum performance/power
consumption that is supported by your NonStop configuration. This mode ensures
maximum performance, but does not provide any power savings. This is the default
mode for all systems, including shipped systems.
HP Static High Performance Mode
(default)
In Dynamic Power Savings Mode, IPUs
2
run at maximum power/performance until
an IPU idles. Once the IPU idles (and as long as it does not need to off-load work
from other IPUs) it moves to the Itanium power saving state until a task needs to run
on it, whereupon the IPU executes instructions at maximum power/performance
again.
HP Dynamic Power Savings Mode
In Static Low Power Mode, the CPU is set to a lower power state. This state saves
power by having the CPU operate at a lower frequency, with resulting lower
performance capacity. The performance impact is workload-dependent.
HP Static Low Power Mode
1
CPU is a Logical Processor that consists of a set of one or more IPUs.
2
IPU (Instruction Processing Unit) is a microprocessor core.
NOTE: The OS Control Mode is not supported on NonStop systems. If OS Control Mode is
selected, the command will fail, and the Power Regulator setting is left unchanged.
The first time Power Regulator is enabled for a CPU, Dynamic Power Savings Mode becomes the
default Power Regulator setting, unless a different Power Regulator setting is stored in the iLO flash
memory. When a command is issued to alter the Power Regulator setting, iLO stores the new Power
Regulator setting in iLO flash memory, and that new Power Regulator setting becomes the default.
The OSM Service Connection provides the action Enable/Disable Blade Power Regulator
Management on the System object to control the participation of a NonStop BladeSystem in Power
Regulator.
