IMM2 Power Capping and Power Monitoring

The 'Server Management Power' page in the IMM2 settings allows for power capping
(throttling) and power allocation and monitoring of the X6 hardware to help manage
the systems power usage and consumption. The following sections discusses both of
these features of the IMM2.

Enabling Power Capping

From the IMM2 'Server Power Management' page, under the 'Policies' tab, you can
set 'Power Limiting/Power Capping'. The below image is a screenshot of the power
capping policy page. Note that setting a power capacity limit works by throttling the
hardware's performance (such as the CPU) so it will produce less power.
Ensure you confirm your servers power consumption via the power monitoring tools
in the IMM2. The power monitoring and allocation tool is discussed in the next
section. You do not want to set the power capacity limit too low and risk exceeding the
power capacity limit. In the event you exceed the power capacity limit the server
and/or some of its components may not power on.
