Distributed uninterruptible power supply

摘要

A distributed uninterruptible power supply provides power to a system including a plurality of electronic computing devices. Each electronic computing device may include an on-board battery to provide power when a power outage occurs. The electronic computing devices that are executing processes that may be temporarily suspended without adversely impacting the processing of a majority of the plurality electronic computing devices may be identified as sacrificial devices. The motherboard of each sacrificial device may be deactivated to suspend any executing processes. The DC power provided by the on-board battery of each sacrificial device may be converted to AC power and then supplied to the non-sacrificial devices.

主权项

1. A method comprising:
receiving, using one or more computing devices, an indication that a power outage occurred; identifying, using the one or more computing devices, which of a plurality of electronic devices is a sacrificial device, wherein processing in the sacrificial device may be suspended; deactivating, using the one or more computing devices, the processing of the sacrificial device; supplying, using the one or more computing devices, alternating current (AC) power from the sacrificial device to one or more non-sacrificial devices; and identifying, using the one or more computing devices, the sacrificial device as a new non-sacrificial device when one or more processes associated with the one or more non-sacrificial devices are awaiting a result of a suspended process of the sacrificial device; activating, using the one or more computing devices, the new non-sacrificial device.
