More Information
Summary:Methods and apparatus are provided for improving communication between processors in separate computer systems. Components and peripherals in individual computer systems communicate using input/output (I/O) buses such as PCI Express buses. The I/O buses are extended to allow interconnection between computer systems without having to introduce network infrastructure. A transfer controller supporting Direct Memory Access (DMA) is provided to allow even more efficient communication between computer systems.
