Managing And Monitoring Power; Redundancy Policies - Dell PowerEdge FX2 User Manual

Managing and monitoring power

The PowerEdge FX2/FX2s chassis is the most power-efficient server enclosure. It is designed to include highly efficient power
supplies and fans, has an optimized layout for the air to flow more easily through the system, and contains power-optimized
components throughout the enclosure. The optimized hardware design is coupled with sophisticated power management
capabilities that are built into the Chassis Management Controller (CMC), power supplies, and iDRAC to allow you to further
enhance power-efficient server environment.
Power management in PowerEdge FX2/FX2s is relatively different from PowerEdge VRTX. One major change in the power
management technique is the use of a Closed Loop System Throttle (CLST) to maintain the desired chassis power cap. The
purpose of using this technique is that, it has a better control, also allows the chassis to make full use of the available PSU.
The Power Management features of PowerEdge FX2/FX2s help administrators configure the enclosure to reduce power
consumption and to adjust the power as required specific to the environment.
The PowerEdge FX2/FX2s enclosure consumes AC power and distributes the load across the active power supply unit (PSU). The
system can deliver up to 3371 Watts of AC power that is allocated to server modules and the associated enclosure infrastructure.
However, this capacity varies based on the power redundancy policy that you select.
The PowerEdge FX2/FX2s enclosure can be configured for any of the three redundancy policies that affect PSU behavior and
determine how chassis Redundancy state is reported to administrators.
You can also control Power management through OpenManage Power Center (OMPC). When OMPC controls power externally,
CMC continues to maintain:
• Redundancy policy
• Remote power logging
OMPC then manages:
• Server power
• System Input Power Capacity
NOTE: Actual power delivery is based on the configuration and workload.
You can use the CMC web interface or RACADM to manage and configure power controls on CMC:
• View the status for the chassis, servers, and PSUs.
• Configure power budget and redundancy policy for the chassis.
• Execute power control operations (turn on, turn off, system reset, power-cycle) for the chassis.

Redundancy policies

Redundancy policy is a configurable set of properties that determine how CMC manages power to the chassis. The following
redundancy policies are configurable:
• Grid Redundancy
• No Redundancy
• Redundancy Alerting Only
