Switchable backup battery for layered datacenter components

摘要

Systems and methods for handling battery backup resources in a computer system differently in certain situations, such as catastrophic events, based upon an assigned layer of the datacenter components to which the battery backup resource provides backup power. The layer can be based, for example, on criticality of the resource to the system. Less critical layers can shed load or gracefully shut down to respond to the event, and the battery resources can be reallocated or reconfigured to provide battery power to the more critical layers.

1. A computer-implemented method for managing datacenter components in a datacenter, comprising:
under the control of one or more computer systems configured with executable instructions,
maintaining information about a plurality of datacenter components in a datacenter and a plurality of layers of the datacenter components, the information including, for each of the plurality of datacenter components, an assigned one of the plurality of layers for the datacenter component;receiving information about an event related to the datacenter, the information indicating that a backup battery resource supporting the datacenter is insufficient to support the plurality of layers of the datacenter components;identifying at least one layer of the plurality of layers to be maintained in the datacenter;determining a desired voltage level representing a total voltage sufficient for the at least one layer of the plurality of layers to be maintained based on power consumption requirements of each of the components included in the at least one layer; andin response to receiving the information about the event:
providing information for reducing power consumption of each of the plurality of datacenter components in accordance with the assigned layer for the datacenter component, such that power consumption is reduced for datacenter components assigned to layers other than the at least one layer; andproviding information for changing the configuration of the backup battery resource for said plurality of datacenter components in accordance with the reduced power consumption of said at least one of the plurality of datacenter components, the information for changing the configuration being configured to result in restoring the voltage level of the backup battery resource to the desired voltage level.
