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

Managing and Monitoring Power

The Dell PowerEdge VRTX chassis is the most power-efficient modular 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.
The Power Management features of the PowerEdge VRTX help administrators configure the enclosure to reduce power
consumption and to adjust the power as required specific to the environment.
The PowerEdge VRTX modular enclosure consumes AC power and distributes the load across all active internal power
supply units (PSUs). The system can deliver upto 5000 Watts of AC power that is allocated to server modules and the
associated enclosure infrastructure. However, this capacity varies on the basis of power redundancy policy you select.
The PowerEdge VRTX enclosure can be configured for any of the two 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
• Dynamic power supply engagement (DPSE)
OMPC then manages:
• Server power
• Server priority
• System Input Power Capacity
• Maximum Power Conservation Mode
NOTE: Actual power delivery is on the basis of configuration and workload.
You can use the CMC web interface or RACADM to manage and configure power controls on CMC:
• View power allocations, consumption, and 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 with or without dynamic PSU engagement:
• AC redundancy
• Power supply redundancy
