Abstract: An HA system includes a first IOM having a first switch, a second IOM having a second switch, and a plurality of slot modules configured to be connected to a plurality of SSDs, respectively. Each of the slot modules has Port A? configured to be connected to the first IOM and Port B? configured to be connected to the second IOM. In response to detecting a connection of one of the SSDs to one of the slot modules, the first and second IOMs determine whether the SSD is a single-port type SSD. When it is determined that the SSD is a single-port type SSD, the first IOM controls the first switch to link up to said one of the slot modules and the second IOM controls the second switch to unlink said one of the slot modules.

Abstract: A method of data synchronization is to be implemented by a redundant server system including an active input/output module (IOM) and a passive IOM. The method includes: allocating a primary transfer buffer in the active IOM; allocating a secondary transfer buffer in the passive IOM; collecting pieces of secondary dedicated-sensor data, and storing the pieces of secondary dedicated-sensor data in the primary transfer buffer at once; collecting pieces of primary dedicated-sensor data; after the pieces of primary dedicated-sensor data have been collected, updating the primary state data based on the pieces of primary dedicated-sensor data thus collected and the pieces of secondary dedicated-sensor data stored in the primary transfer buffer at once, and storing the primary state data thus updated in the secondary transfer buffer; and updating the secondary state data based on the primary state data that have been updated and that are stored in the secondary transfer buffer.

Abstract: An integrated control management system includes an input output device. The input output device includes a database, a memory module, a first processing module, and a second processing module. The memory module receives and stores a plurality of integrated control commands, and one of the integrated control commands is generated based on a hardware control command for setting a hardware control transmitted by another input and output device. The first processing module reads the integrated control command from the memory module and obtains the hardware control data from the integrated control command. The first processing module updates the hardware control data to the database. The second processing module reads the database and updates the hardware control data stored in the database to another database in another input output device. The second processing module sets the hardware control based on the hardware control data stored in the database.

Abstract: A boot method for an embedded system is provided. The embedded system includes two mainboards each provided with a baseboard management controller (BMC), a non-volatile memory unit and a network adapter. When the embedded system is turned on, each of the BMCs performs a boot procedure, and then loads an operating system (OS) image file from a corresponding non-volatile memory unit to execute an operating system. When one BMC fails to load the OS image file or to execute the operating system, the BMC causes the corresponding network adapter to communicate with the other network adapter to acquire the OS image file from the non-volatile memory unit on the other mainboard, so as to replace the OS image file in the corresponding non-volatile memory unit, and directly loads the OS image thus acquired to execute the operating system.
