Abstract:
A SAS expander forms a first path coupling the SAS initiator and a first port of a SAS target together. The first SAS expander notifies the SAS initiator of a virtual expander address instead of a SAS address of the first SAS expander. The first SAS expander notifies the SAS initiator of a virtual target port address, at least instead of a SAS address of the first port of the SAS target. A second SAS expander forms a second path coupling the SAS initiator and a second port of the SAS target together. The second SAS expander notifies the SAS initiator of the virtual expander address instead of a SAS address of the second SAS expander. The second SAS expander notifies the SAS initiator of the virtual target port address, at least instead of a SAS address of the second port of the SAS target.
