Abstract:
1. A method comprising: at a failover device that connects redundant first and second virtualized input/output controller devices each comprising multiple virtual network interfaces that are in an active or standby state at any given time, to a computing device that hosts one or more processes, broadcasting transactions in accordance with a computer expansion card standard initiated from the computing device to the first and second virtualized input/output controller devices, wherein the failover device is separate and independent from the first and second virtualized input/output controller devices and the computing device; receiving, at the failover device, signals associated with upstream transaction completions in accordance with the computer expansion card standard for both active and standby virtual network interfaces on the first and second virtualized input/output controller devices; and forwarding, by the failover device, signals associated with upstream transaction completions for active virtual network interfaces on the first and second virtualized input/output controller devices to the computing device.
