Abstract: The present disclosure describes example service takeover methods, storage devices, and service takeover apparatuses. In one example, when a communication fault occurs between two storage devices in a storage system, the two storage devices respectively obtain running statuses of the two storage devices. A running status can reflect current usage of one or more system resources of a particular storage device. Then, a delay duration is determined according to the running statuses, where the delay duration is a duration for which the storage device waits before sending an arbitration request to a quorum server. The two storage devices respectively send, after the delay duration, arbitration requests to the quorum server to request to take over a service. The quorum server then can select a storage device in a relatively better running status to take over a host service.

Abstract: Embodiments of the present invention provide a receiver and a wireless communications apparatus. The receiver includes: an attenuation circuit, configured to receive an input signal, and obtain a first signal according to the input signal; a low-noise amplification circuit, configured to receive the first signal, and obtain a second signal according to the first signal; an orthogonal down-frequency conversion circuit, configured to receive the second signal, and process the second signal to obtain an output signal; and a control circuit, configured to separately control the attenuation circuit and the low-noise amplification circuit according to power of an interference signal included in the output signal, so as to determine whether the attenuation circuit attenuates the input signal and whether the low-noise amplification circuit amplifies the first signal.
