Managing power pooled from multiple shelves of a rack

摘要

A method of managing power to electrical systems in a rack includes pooling power from power supply mechanisms in two or more slots of a rack. Power is supplied from the pooled power to electrical systems in one or more slots in the rack. Power supply mechanisms are activated or deactivated from the pooled power based on conditions of the power supply mechanisms or the electrical systems receiving power from the pooled power supply system.

主权项

1. A system, comprising:
a rack comprising a plurality of shelves configured to hold electrical systems; and a plurality of shelf-mountable electrical systems, wherein each of at least two of the shelf-mountable electrical systems is coupled in one of the shelves, wherein each of at least two of the shelf-mountable electrical systems comprises:
a power supply mechanism comprising a power supply unit configured to receive electrical power from a power distribution system and, while receiving electrical power from the power distribution system, supply DC electrical power to a DC power output of the power supply mechanism; andone or more computing devices; wherein the DC power outputs of the power supply mechanisms in at least two of the shelves are coupled to one another to form a pooled power supply system comprising a pooled power output, wherein the pooled power supply system is configured to supply power from the power supply mechanisms to computing devices on one or more of the shelf-mountable electrical systems, wherein the pooled power supply system is configured to activate or deactivate one or more of the power supply mechanisms of the pooled power supply system based on one or more conditions of the power supply mechanisms or the computing devices receiving power from the pooled power supply system.
