Abstract:
A method of disposing components on a system board mounted on a chassis of an information processor, said system board having main components including a plurality of processor elements mounted thereon and connected together by a processor bus, said method comprising the following steps:disposing said plurality of processor elements on said system board in one line that is in parallel with a first edge of said system board;disposing expansion board slots and a memory board connector in a region on said system board opposite to the first edge such that long sides thereof are in parallel with the first edge, wherein said expansion board slots are each arranged to receive therein an expansion board on which an I/O interface is mounted, said I/O interfaces are connected by an I/O bus, and said memory board connector is arranged to be connected to a memory board on which a memory is mounted; anddisposing a bridge LSI and memory controllers in regions which are located along the extension direction of the long sides of said expansion board slots and said memory board connector, wherein said bridge LSI executes protocol conversion between said processor bus and said I/O bus, said memory controllers control access to the memory on said memory board, and said regions are adjacent to both of the region in which said expansion board slots and said memory board connector are disposed and the region in which said plurality of processor elements are disposed.
