2.7.2 System power settings
Power settings include basic power-related configuration options:
IBM Systems Director Active Energy Manager™ (Default: Capping Enabled)
The Active Energy Manager option enables the server to use the power capping feature of
Active Energy Manager, an extension of IBM Systems Director.
Active Energy Manager measures, monitors, and manages the energy and thermal
components of IBM systems, enabling a cross-platform management solution and
simplifying the energy management of IBM servers, storage, and networking equipment.
In addition, Active Energy Manager extends the scope of energy management to include
non-IBM systems, facility providers, facility management applications, protocol data units
(PDUs), and equipment supporting the IPv6 protocol. With Active Energy Manager, you
can accurately understand the effect of the power and cooling infrastructure on servers,
storage, and networking equipment. One of its features is to set caps for how much power
the server can draw.
