Power Management
Overview
The Dell PowerEdge M1000e server enclosure is the most power-efficient
modular server in the market. It is designed to include highly-efficient power
supplies and fans, has an optimized layout so that air flows more easily
through the system, and contains power-optimized components throughout
the enclosure. The optimized hardware design is coupled with sophisticated
power management capabilities built into the Chassis Management
Controller (CMC), power supplies, and iDRAC to allow you to further
enhance power efficiency and to have full control over your power
environment.
The PowerEdge M1000e modular enclosure takes in AC power and
distributes the load across all active internal power supply units (PSUs).
The system can deliver up to 11637 Watts of AC power that is allocated to
server modules and the associated enclosure infrastructure.
NOTE: Actual power delivery is based on configuration and workload.
The Power Management features of the M1000e help administrators
configure the enclosure to reduce power consumption and to tailor power
management to their unique requirements and environments.
The PowerEdge M1000e enclosure can be configured for any of three
redundancy policies that affect PSU behavior and determine how chassis
Redundancy state is reported to administrators.
AC Redundancy Mode
The purpose of the AC redundancy policy is to enable a modular enclosure
system to operate in a mode in which it can tolerate AC power failures.
These failures may originate in the AC power grid, the cabling and delivery,
or a PSU itself.
