Abstract: A method for performing destination power management with aid of source data statistics in a storage system and associated apparatus are provided. The method includes: monitoring an accumulated data size of source data in at least one target object of a file system of a main storage server that have not been replicated and transmitted to a destination storage sub-system, where the destination storage sub-system is positioned in the storage system and positioned outside the main storage server, and the destination storage sub-system is utilized for storing a replication version of the source data; and according to the accumulated data size, dynamically determining whether to turn on or turn off the destination storage sub-system, where generation of the replication version is performed after turning on the destination storage sub-system, and turning off the destination storage sub-system is performed after the generation of the replication version.

Abstract: A storage system has a plurality of physical blocks, a buffer and a controller. In response to an unmap command received from an operating machine, the controller moves a mapping between a physical block and a logical block of the storage system to a buffer to prepare a deallocation procedure. Then, the controller transmits a completion response to the operating machine. The unmap command is used to cancel the mapping, the completion response is used to notify the operating machine that execution of the unmap command has been finished, and the deallocation procedure is used to deallocate the physical block according to the mapping in the buffer. After the completion response has been transmitted to the operating machine, the controller deallocates the physical block according to workload of the storage system.

Abstract: An interface device coupled between a computer system and a display system. The interface device includes a control module. The control module receives data from the computer system, and determines whether to display the data on the display system in a projection mode or in a media rendering mode according to operation signals inputted by a user. In the projection mode, the data includes static pictures. The control module projects the static pictures onto the display system in sequence. In the media rendering mode, the data includes a video stream. The control module controls the video stream to be transmitted from the computer system to the display system and controls the playback of the video stream on the display device. When in the projection mode and when the operation signal indicates that switching to the media rendering mode is required, the media rendering mode is activated in the projection mode.
