Highly parallel PCI bus architecture in the ProLiant ML530 Figure 3. Triple-peer PCI bus architecture in the ProLiant 8000 PCI bridges are not limited to the computer system; controllers can include them also. Hardware manufactures such as Compaq include PCI bridges on controllers to help with signal integrity, enabling more devices to be added per system. Data transfers from the host bus, through the primary PCI bus, through the PCI-to-PCI bridge on the controller, and finally to the PCI device. For example, an intelligent device such as a Smart Array 4250ES Controller contains a PCI bridge. 13UK-1200A-WWEN
