Abstract: The present disclosure relates to systems and methods for power outage protection. The system may obtain a read/write signal of each of a plurality of storage devices. For each of the plurality of storage devices, the system may identify a state of the storage device based on the read/write signal of the storage device. The state of the storage device may include a read/write state or an idle state of the storage device. In response to an interruption of power supply to the plurality of storage devices, the system may selectively provide electric power to the plurality of storage devices using a power source based at least partially on the states of the plurality of storage devices.

Abstract: Systems and methods for data storage are provided. The systems may include one or more storage modules and one or more computing modules. The systems may obtain data to be processed. The systems may determine a required storage bandwidth based on the data to be processed. The systems may determine a distribution mode of a current computing bandwidth of the one or more computing modules based on a current storage bandwidth of the one or more storage modules and the required storage bandwidth.

Abstract: Dual-controller storage systems and methods for controlling the dual-controller storage systems are provided. The dual-controller storage system may include a first controller, a second controller, at least one expander, a first storage array, and a second storage array. The at least one expander may be connected with the first controller, the second controller, the first storage array, and the second storage array. The first controller and the second controller may be communicatively connected via a network. When the first controller and the second controller both work in a normal state, the first controller may be configured to control the first storage array, and the second controller may be configured to control the second storage array. The first controller and the second controller may work in synchronization.
