Abstract: In a storage system, a control device determines that at least one first storage device of X storage devices is out of service. Then, the control device selects a second storage device from the X storage device. A quantity of stripe members of a data stripe stored in the second storage device is less than a ratio of T divided by X. The control device further writes target data into the second storage device. The target data is a data unit or a check unit used to update at least one stripe member of the data stripe stored in the first storage device.

Abstract: This disclosure provides a communication method and apparatus. In the method, the first network device receives a first position from a second network device, where the first position is a position of one or more subframes occupied by first information; determines a first offset and configures a multicast-broadcast single-frequency network (MBSFN) subframe, where the first offset is for determining a second position, the second position is a position obtained by offsetting the first position by the first offset, the first range is a position that supports configuration of the MBSFN subframe, and a position of the MBSFN subframe includes the second position; and sends the first offset and first MBSFN configuration information to the second network device. According to the method, the second network device may send the first information on the MBSFN subframe, to avoid time-frequency resource conflicts between the first information and a cell reference signal (CRS).

Abstract: This application relates to an optical receiver. The optical receiver includes a photodetector and a trans-impedance amplifier that includes a first differential branch circuit, a second differential branch circuit, and a differential amplifier. The first differential branch circuit includes a first capacitor and a first trans-impedance amplifying unit, where an input end of the first capacitor receives an input signal from a power supply end of the photodetector, and an output end of the first capacitor is coupled to an input end of the first trans-impedance amplifying unit. The first differential branch circuit is configured to: amplify the input signal and output a reference signal. The second differential branch circuit is configured to amplify an electrical signal from the photodetector. Signal physical parameter values of the reference signal and an interference signal included in an amplified electrical signal are the same or similar.
