Abstract
A controller shareable by a plurality of operating system domains (OSDs) for communication on a network is disclosed. The controller includes a port for coupling to the network. The port transceives packets with the network for each of the plurality of OSDs. The controller also includes a plurality of replicated programming interfaces that each receive from a respective one of the plurality of OSDs a request to obtain a port ID for the port from the network. The controller obtains from the network a distinct port ID for each of the plurality of OSDs in response to the respective request. The request comprises one or more load-store transactions. In one embodiment, the controller is a shared Fiber Channel controller.
