摘要： A storage system is provided comprising a controller and a memory comprising a plurality of tiles of memory organized in a plurality of tile groups, wherein a given tile group is busy when any tile in the given tile group is busy. The controller is configured to: inform the host of the busy status of the plurality of tile groups; receive a plurality of commands from the host, wherein each command is provided with a different tile group identifier of a tile group that is not busy; and execute the plurality of commands, wherein because each command comprises a different tile group identifier of a tile group that is not busy, the plurality of commands are executed in parallel.
