A data storage system includes an interface circuit configured to receive a read request for a chunk of data; a disk array including a plurality of main disks and a plurality of sub disks; an input/output control circuit configured to read a chunk from the main disks according to the read request; a data mapping circuit configured to store mapping relations between logical addresses and physical addresses of chunks; and a data relocation control circuit configured to control relocation of chunks stored in the disk array. The data relocation control circuit is configured to control movement of a first chunk stored in a main disk in an overloaded state to a main disk in an underloaded state, and to control movement of a second chunk stored in a sub disk to a main disk which can accommodate a required bandwidth of the second chunk.

Data storage system including a data relocation circuit and a plurality of data storage devices and operation method thereof

Disclosed is a method for assigning and scheduling a task for maximizing video quality of a transcoding server using heterogeneous processors. A method performed by a transcoding server configured with heterogeneous processors may include receiving a request for video transcoding for a video encoded based on a variable bitrate (VBR), predicting transcoding information for assigning a transcoding task in response to the received request for video transcoding, and determining information on a node to which a transcoding task is to be assigned and preset option information for the transcoding based on a result of the predicted transcoding information.
