ABSTRACT:
A multi-computer system has many processors that share peripherals. The peripherals are virtualized by hardware without software drivers. Remote peripherals appear to the operating system to be located on the local processor's own peripheral bus. A processor, DRAM, and north bridge connect to a south bridge interconnect fabric chip that has a virtual Ethernet controller and a virtual generic peripheral that act as virtual endpoints for the local processor's peripheral bus. Requests received by the virtual endpoints are encapsulated in interconnect packets and sent over an interconnect fabric to a device manager that accesses remote peripherals on a shared remote peripheral bus so that data can be returned. Ethernet Network Interface Cards (NIC), hard disks, consoles, and BIOS are remote peripherals that can be virtualized. Processors can boot entirely from the remote BIOS without additional drivers or a local BIOS. Peripheral costs are reduced by sharing remote peripherals.
