Managing and Monitoring Power
The PowerEdge VRTX chassis is the most power-ecient modular server enclosure. It is designed to include highly ecient power
supplies and fans, has an optimized layout for the air to ow 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-
ecient server environment.
The Power Management features of the PowerEdge VRTX help administrators congure the enclosure to reduce power
consumption and to adjust the power as required specic 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 up to 4800 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 VRTX enclosure can be congured for any of the two redundancy policies that aect 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 based on conguration and workload.
You can use the CMC web interface or RACADM to manage and congure power controls on CMC:
• View power allocations, consumption, and status for the chassis, servers, and PSUs.
• Congure power budget and redundancy policy for the chassis.
• Execute power control operations (turn on, turn o, system reset, power-cycle) for the chassis.
Redundancy Policies
Redundancy policy is a congurable set of properties that determine how CMC manages power to the chassis. The following
redundancy policies are congurable with or without dynamic PSU engagement:
• Grid redundancy
• Power supply redundancy
Grid Redundancy Policy
The purpose of the Grid 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.
