发明名称 Interrupt-driven link status feedback mechanism for embedded switches
摘要 A computer implemented method, a tangible computer readable medium, and a data processing system intelligently propagate link status information received by a blade server to the various ports of an embedded multi-port switch. The link status of a switch port in an external switch module can be communicated to the operating systems of individual blade servers that are affected by that link status. When an external switch module is unplugged from a server blade chassis, the bus controller broadcasts a link down event, such as a link down interrupt, to the individual server blades where it is received by the embedded multi-port switch for those server blades. The embedded multi-port switch translates the link down interrupt into a hardware link down event, and forwards the hardware link down event to the other elements connected to the embedded multi-port switch.
