Abstract
A data processing system includes first and second data processing devices coupled to each other through a midplane. Each data processing device includes a data storage processor; a root complex coupled to the data storage processor; and a switch device coupled between the root complex and at least one end point device. The switch device includes a first transparent bridge coupled to the root complex and a second transparent bridge coupled between the first transparent bridge and the at least one end point device, a first data path connected between the first transparent bridge and the midplane and a second data path connected between the first transparent bridge and the midplane through a non-transparent bridge. The first data path of the first data processing device is connected to the second data path of the second data processing device through the midplane and the second data path of the first data processing device is connected to the first data path of the second data processing device through the midplane, such that data transmitted between the root complexes of each of the first and second data processing devices is transmitted through only one non-transparent bridge.
