Figure 39: FCIP fully redundant configuration
Note: For multiple paths between SANs, multiple pairs of systems deployed for FCIP
need to be connected to the FC hosts or FC devices. However, multiple SR2122-2
Storage Routers deployed for FCIP cannot be configured in an HA cluster. It is assumed
that the multipath management is being done by an entity outside the SR2122-2 (for
example, by management applications on the FC host or storage devices).
Figure 40 shows an alternative network structure for FCIP in which FCIP tunnels
are established from two SANs aggregated to a central site. The SR2122-2 at the
central site has one FCIP instance set up for SAN 1 and the other FCIP instance
set up for SAN 2.
