SEQUENTIAL POWER UP OF DEVICES IN A COMPUTING CLUSTER BASED ON RELATIVE COMMONALITY

摘要

A method of powering on a plurality of devices includes identifying a plurality of power distribution units (PDUs) disposed in a rack, wherein each PDU receives power from a main power source and includes a circuit breaker. A plurality of devices disposed in the rack are identified, wherein each device receives power from one of the PDUs, and wherein the plurality of devices are server nodes, network switches or external data storage devices. Vital product data (VPD) is obtained from a service processor in each device, wherein the VPD identifies the device by a model identification code. For each PDU, the plurality of devices connected to the PDU are powered on in a sequence to prevent an inrush current from tripping the circuit breaker within the PDU, wherein the sequence powers on devices in order of ascending commonality of the model identification code.

1. A method, comprising:
identifying a plurality of power distribution units disposed in a rack, wherein each power distribution units is connected to received power from a main power source, and wherein each power distribution unit includes a circuit breaker; identifying a plurality of devices disposed in the rack, wherein each device is connected to receive power from one of the power distribution units, and wherein the plurality of devices are selected from server nodes, network switches and external data storage devices; obtaining vital product data from a service processor in each device, wherein the vital product data identifies the device by a model identification code; and for each of the power distribution units, powering on the plurality of devices that are connected to the power distribution unit in a sequence to prevent an inrush current from tripping the circuit breaker within the power distribution unit, wherein the sequence powers on devices in order of ascending commonality of the model identification code.
