Abstract: A data management apparatus, a data management method, and a data storage device are provided. The data management apparatus includes a management unit and a data migration unit. The management unit manages data transmission channels between two types of storage media with different transmission performance. Then, the data migration unit migrates data between the two types of storage media through the managed data transmission channels. In this way, the data management apparatus can directly migrate data between storage media with different transmission performance, and a CPU in a system does not need to perform processing such as instruction conversion and protocol conversion, so that a delay of performing the foregoing processing by the CPU can be shortened. In addition, because the CPU does not need to perform data migration, resource overheads of the CPU can be reduced.

Abstract: A method for setting a working mode of a multi-processor system includes: detecting, after a current board is inserted into a slot of the backplane, whether an associated board exists on the backplane; detecting, if the associated board exists, whether the associated board is in an independent working state; powering on the current board according to a slave working mode if the associated board is not in an independent working state, so as to work coordinately with the associated board; detecting, within a predetermined detection time if the associated board does not exist, whether a board is inserted into another slot of the backplane except the slot of the master board; and powering on the current board according to a master working mode if it is detected that the board is inserted, so as to work coordinately with the board in the other slot.
