Partition power management

Available with Active Energy Manager 4.3.1 or later, and POWER7 systems with the 730 
firmware release or later, is the capability to set a power savings mode for partitions or the 
system processor pool. As in the system-level power savings modes, the per-partition 
power savings modes can be used to achieve a balance between the power consumption 
and the performance of a partition. Only partitions that have dedicated processing units 
can have a unique power savings setting. Partitions that run in shared processing mode 
have a common power savings setting, which is that of the system processor pool. The 
reason is because processing unit fractions cannot be power-managed.

In the case of system-level power savings, two Dynamic Power Saver options are offered: 

– Favor partition performance
– Favor partition power savings

The user must configure this setting from Active Energy Manager. When dynamic power 
saver is enabled in either mode, system firmware continuously monitors the performance 
and utilization of each of the computer’s POWER7 or  processor cores that 
belong to the partition. Based on this utilization and performance data, the firmware 
dynamically adjusts the processor frequency and voltage, reacting within milliseconds to 
adjust workload performance and also deliver power savings when the partition is 
underused.

In addition to the two dynamic power saver options, you can select to have no power 
savings on a given partition. This option keeps the processor cores assigned to the 
partition running at their nominal frequencies and voltages.

A power savings mode, referred to as 

inherit host setting

, is available and is applicable 

only to partitions. When configured to use this setting, a partition adopts the power 
savings mode of its hosting server. By default, all partitions with dedicated processing 
units, and the system processor pool, are set to the inherit host setting.

On POWER7 and processor-based systems, several EnergyScale 
technologies are embedded in the hardware and do not require an operating system or 
external management component. More advanced functionality requires Active Energy 
Manager (AEM) and IBM Systems Director.

Table 2-31 lists all features that are supported, showing all cases in which Active Energy 
Manager (AEM) is not required, and also details the features that can be activated by 
traditional user interfaces (for example, ASMI and HMC).
