How to implement the node port virtualization in Fiber Channel, apparatus, and systems

摘要

The present invention relates to the field of communications technologies, and in particular, to a method, apparatus, and system for implementing node port virtualization on a fibre channel. Multiple different virtual N_port IDs are allocated to each of multiple N ports, of an NPV switch, corresponding to an N_port ID of a remote node. Because a virtual N_port ID is allocated, to each remote node, for more than one N_port of the NPV switch, regardless of which N_port of these N_ports a node connected to the NPV switch is registered for, the node can obtain the virtual N_port ID that is of each remote node and that is corresponding to the N_port. Therefore, any node connected to the NPV switch can communicate with any remote node, thereby improving communication efficiency.
