Figure 47 Example: Fibre Channel to IP port/target translation
.
The iSCSI Initiator discovers the targets presented out of the mpx100/100b GE ports by discovering
the GE port's IP addresses and logging in to the target (see
Figure 48 ).
Figure 48 Example: Single mpx100 iSCSI port IP addressing
.
Each iSCSI GbE port has duplicate paths to the LUN because each GE port is presenting two unique
targets with the same LUN information. Each unique target should be considered an iSCSI path to
the LUN.
iSCSI Initiator perspective
Because of the mpx100's/100b's ability to present multiple Fibre Channel targets through one physical
iSCSI GbE connection, it is possible for the iSCSI Initiator to connect—and use—more virtual paths
than are physically available on the FC/IP networks.
NOTE:
Using the iSCSI target discovery process, it is up to the iSCSI Initiator to determine how many targets
to log in to, bearing in mind that one target equals one path.
For the preceding examples, Table 16 shows all the paths available to an iSCSI Initiator connected
to both iSCSI GbE Ports of the mpx100/100b.
