Routing through an IP network
When connecting fabrics through IP, 1606 Extension SAN Switches or DC Dir Switch MP Extension
Blades, MP Routers or Blades serve as FCIP gateways with Fibre Channel routing. Routers that
communicate with the FCIP protocol must be installed in pairs (Figure 28 and Figure 29).
HP supports FCIP configurations in which 1606 Extension SAN Switches or DC Dir Switch MP
Extension Blades, 400 MP Router or MP Router Blade serve as an FCIP gateway and a Fibre
Channel switch. Servers and storage systems that support Continuous Access with FCIP can be
directly connected to the Fibre Channel ports on the 1606 Extension SAN Switches or DC Dir
Switch MP Extension Blades (Figure 28), 400 MP Router or MP Router Blade (Figure 37).
