Active Energy Manager Console
Active Energy Manager Console provides the GUI to AEM in IBM Director
Console. AEM Console displays rack-mounted servers and BladeCenter chassis
at the same level in the navigation tree. Rack-mounted servers are represented
by leaf nodes (lowest point in the tree), while BladeCenter chassis have
sub-nodes representing the power domains and modules within the chassis.
When you install AEM Server, AEM Console is installed automatically. You can
also install AEM Console on all management consoles from which a system
administrator remotely accesses the management server and performs AEM
tasks.
Active Energy Manager Database
The Active Energy Manager Database stores information collected by AEM
Server. AEM saves configuration information and historical power and
temperature data for managed systems in a Derby database. The AEM Database
is created in the Data subdirectory of the IBM Director installation directory.
When you uninstall IBM Director Server, it does not remove the AEM Database
unless you request that customizations be deleted during the uninstallation of
IBM Director Server. The size of the AEM Database directly correlates to the
short-term data-collection interval, the long-term data-collection interval, and the
number of days that short-term and long-term trend data is kept. All of these
values are configurable. You can control them and the size of the AEM Database
by using the Manage Trend Data window.
Managed systems
Active Energy Manager can monitor power consumption for selected rack
servers, BladeCenter chassis and blade servers, and intelligent PDUs.
You can implement each rack server, or modular system, which enables power
capping features to provide the power measurement information to the AEM.
Older server or expansion units, that do not have this feature can be
implemented by using iPDUs. See 6.8, "Power Distribution Units (PDU)" on
page 357. The iPDUs monitor the power usage on their outlets and provide the
captured information by the integrated SNMP out-of-band support.
The power capping feature in the BIOS of your x3850 M2 and x3950 M2, as
shown in Figure 6-24 on page 338, is enabled by default. This feature is available
for single node x3950 M2 systems. For details see section 3.1.3, "Processor
(CPU) configuration options" on page 99.
