Computing system and operating method thereof

A computing system and an operating method thereof are provided. A computing system includes a first storage device, a second storage device, a memory device, and a computing fast link (CXL) switch. The memory device stores first mapping data of the first storage device and second mapping data of the second storage device. The CXL switch is connected to the first storage device, the second storage device, and an external host through a first interface, and arbitrates communication between the first storage device, the second storage device, and the external host. The first storage device is connected with the memory device through the second interface. The second storage device is connected with the memory device through the third interface. The first interface, the second interface, and the third interface are physically separated from each other. 提供一种计算系统及其操作方法。计算系统包括第一存储装置、第二存储装置、存储器装置和计算快速链路(CXL)交换机。存储器装置存储第一存储装置的第一映射数据和第二存储装置的第二映射数据。CXL交换机通过第一接口与第一存储装置、第二存储装置和外部主机连接，并且仲裁第一存储装置、第二存储装置和外部主机之间的通信。第一存储装置通过第二
