High-availability router configurations
In high-availability configurations, use pairs of 8 Gb/s switches with integrated Fibre Channel
routing, 1606 Extension SAN Switches, routers, or IFL pairs to provide redundant paths between
fabrics. Figure 31 (page 56) and Figure 32 (page 57) show valid configurations.
• The first configuration shows servers and storage connected using a pair of redundant fabrics
in a level 4 NSPOF configuration. For information about high-availability levels, see “Data
availability” (page 38).
• The second configuration shows routers cross-wired to provide full fabric connectivity in case
a router fails.
• The third configuration shows multiple IFLs between the 1606 Extension SAN Switch or MP
Router and edge fabrics to provide redundancy in case an IFL or MP Router port fails.
The configurations show a small number of SAN fabrics connected to each router. The same
principles apply to configurations with a higher number of fabrics connected to a router, and a
higher number of routers in a Meta SAN. For scalability rules, such as the maximum number of
fabrics and MP Routers, see “B-series switches and fabric rules” (page 91).
