Abstract:
1. A computer-implemented method in a storage area network that includes a switched-fabric for securing access to storage node ports, said computer-implemented method comprising: specifying authorized combinations of fabric port identifiers and node port identifiers in an association table, wherein the authorized combinations are the only combinations that are permitted to access a particular storage node port; receiving, from a device, a request to access said particular storage node port; determining a particular node port identifier, from said request, that identifies a particular node port that is included in said device that is attempting to access said particular storage node port; determining a particular fabric port identifier that identifies a particular fabric port that is included in a switch through which said device transmitted said request; and determining, using the association table, whether a particular combination of said particular fabric port identifier and said particular node port identifier forms an authorized combination by determining whether said particular combination is stored in said association table, and wherein said particular combination is an authorized combination only if said particular combination is stored in said association table.
