Summary:PURPOSE: A data processing system offering a hot-plug addition/removal function, and a system and a method for hot-plug are provided to offer a hot-plug component with a hot-add/removal function without disturbing a current operation of entire processing system. CONSTITUTION: An MP(Multiprocessor)(200) includes a processor-1(201), a processor-2(202), a memory(504A), and an I/O(Input/Output) channel(506A), and an interconnection fabric(208) interconnecting each component. The MP includes additional connector ports on the interconnection fabric. The connector port includes a hot-plug memory expansion port(521), a hot-plug I/O expansion port(522), and a hot-plug processor expansion port(523). Each expansion port has corresponding configuration logics(509A-509C) and controls a hot-plug operation for respective component. An additional memory(504B) is plugged to the memory expansion port of the interconnection port.
