Abstract
Systems and methods are provided for hosting block storage volumes in a hosted computing environment that are supported by multiple underlying elements and that are distributed among physical host devices in a manner that provides for resiliency of the volumes in instances of power failure. As disclosed herein, a block storage volume may be supported by a combination of underlying elements, such as replicas that store data of the volume and replicated authority nodes that designate authority of a replica to accept writes to the volume. To ensure resiliency to power failure, both replicas and authority nodes can be distributed among physical host devices that are supplied by independent power supplies, such that failure of one independent power supply does not render the volume non-operational.
