Software-defined fail-safe power draw control for rack power distribution units

One or more computer storage media storing computer executable instructions which when executed implement a method for providing software-defined fail-safe power draw control for a rack power distribution unit (PDU), the method comprising:

• identifying, at a PDU power manager, devices that are connected to sockets of a PDU;
• identifying, at the PDU power manager, a power rating for the PDU and power ratings for the sockets of the PDU;
• monitoring telemetry data from the devices;
• and
• based on the telemetry data, dynamically applying power caps to the devices where a sum of the power caps is a percentage of the power rating for the PDU.

A computing system comprising:

• one or more processors;
• and
• computer storage media storing computer executable instructions which when executed implement a method for providing software-defined fail-safe power draw control for a rack power distribution unit (PDU), the method comprising:
• based on a power rating for a PDU and power ratings for sockets of the PDU, applying power caps to devices connected to the sockets of the PDU;
• monitoring power draw of the devices while the power caps are applied to the devices;
• and
• based on the monitored power draw of the devices, causing one or more workloads to be migrated between the devices.
