摘要
A host bus adapter of a target device is associated with a Fiber Channel driver and is connected to a Fiber Channel switch fabric. The host bus adapter receives from the switch fabric an inbound frame having a header including a source identifier and a virtual machine (VM) tag, stores a mapping between the source identifier and the VM tag, and passes the inbound frame to the Fiber Channel driver. The host bus adapter receives from the Fiber Channel driver an outbound frame having a header including a destination identifier, and determines, based on the mapping, whether there is a match at least between the source identifier of the inbound frame and the destination identifier of the outbound frame. If there is a match, the host bus adapter tags the header of the outbound frame with the VM tag, and transmits the tagged outbound frame to the switch fabric.
