Power Monitoring and Power
Management
Dell PowerEdge systems incorporate many new and enhanced power
management features. The entire platform, from hardware to firmware to
systems management software, has been designed with a focus on power
efficiency, power monitoring, and power management.
NOTE: iDRAC6 power management logic utilizes a Complex Programmable Logic
Device (CPLD) present in the blade server. A few platforms also support an
extended CPLD. Updates to CPLD devices are available at the Dell Support website
at support.dell.com under the System Firmware or System Board sections. It is
recommended that you update your blade server with the latest CPLD firmware
version. The current CPLD and the extended CPLD firmware versions (for applicable
platforms) is displayed in iDRAC6 Web GUI.
Dell PowerEdge systems provide many features for monitoring and managing
power:
• Power Monitoring: iDRAC6 collects a history of power measurements
and calculates running averages, peaks, and so on. Using iDRAC6 Web
interface, you can view the information on the
Power Monitoring screen.
You can also view the information in graph form by clicking
Show Graph at
the bottom of the
Power Monitoring screen. See "Power Monitoring" on
page 306 for more information.
•
Power Budgeting: At boot, a system inventory enables a system power
budget of the current configuration to be calculated. See "Power
Budgeting" on page 309 for more information.
•
Power Control: iDRAC6 enables you to remotely perform several
power management actions on the managed system
. See "Power Control"
on page 314 for more information.
