Unified Resource Manager: Energy Management - IBM z13s Technical Manual

IBM Systems Director Active Energy Manager provides customers with the intelligence
necessary to effectively manage power consumption in the data center. Active Energy
Manager, which is an extension to IBM Director Systems Management software, enables you
meter
to
systems. Active Energy Manager uses monitoring circuitry, which was developed by IBM, to
help identify how much actual power is being used, and the temperature of the system.

10.4.5 Unified Resource Manager: Energy management

The energy management capabilities for z Unified Resource Manager can be used in an
ensemble depending on which suite is installed in the ensemble:
Manage Suite (feature code 0019)
Automate Suite (feature code 0020)
Manage Suite
For energy management, the Manage Suite focuses on the monitoring capabilities. Energy
monitoring can help you better understand the power and cooling demand of the z Systems
servers. It provides complete monitoring and trending capabilities for z13s servers and the
zBX by using one or more of the following options:
Monitors dashboard
Environmental Efficiency Statistics

Automate Suite
The z Unified Resource Manager offers multiple energy management tasks as part of the
automate suite. These tasks enable you to change system behaviors for optimized energy
usage and energy saving:
Power cap
Group power cap
Various options are presented, depending on the scope that is selected in the z Unified
Resource Manager graphical user interface (GUI).
Set Power Cap
The power cap function can be used to limit the maximum amount of energy that is used by
the ensemble. If enabled, it enforces power caps for the hardware by throttling the processors
in the system.
The z Unified Resource Manager shows all of the components of an ensemble in the Set
Power Cap window. Because not all components that are used in a specific environment can
support power capping, only those components that are marked as Enabled can perform
power capping functions.
z13s servers support power capping, which gives you the ability to limit the maximum power
consumption and reduce cooling requirements. To use power capping, Automate Firmware
Suite (FC 0020) must be ordered. This feature is used to enable the Automate suite of
functions associated with the IBM z Unified Resource Manager. The Automate suite includes
representation of resources in a workload context, goal-oriented monitoring and management
of resources, and energy management. The Automate suite is included in the base z Systems
CPC at no charge for CPs and zIIPs.
