HP StorageWorks 4000/6000/8000 - Enterprise Virtual Arrays - High-Availability Router Configurations; High-Availability 1606 Extension SAN Switch Configurations

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 33 and Figure 34 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” on page 53.)
• 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” on page 93.
