Abstract:
A method for swapping a system host board in a computer system, comprising the steps of:providing a first CompactPCI bus, the first CompactPCI bus being coupled to a first system processor board having a first system processor and a first system processor board system host, and the first CompactPCI bus being coupled to a first bridge board having a first bridge board system host, wherein the first CompactPCI bus allows the first system processor to control peripheral devices implemented on the first CompactPCI bus, and wherein the first system processor board system host controls the first CompactPCI bus functions;providing a second CompactPCI bus, the second CompactPCI bus being coupled to a second system processor board having a second system processor and a second system processor board system host, and the second CompactPCI bus being coupled to a second bridge board having a second bridge board system host, wherein the second CompactPCI bus allows the second system processor to control peripheral devices implemented on the second CompactPCI bus, and wherein the second system processor board system host controls the second CompactPCI bus functions;providing a first cross connection between the first system processor board and the second bridge board; andtransferring control of the first CompactPCI bus functions from the first system processor board system host to the first bridge board system host when a failure on the first system processor board is detected, thereby swapping the system host from the first system processor board system host to the first bridge board system host.
