Using the FC-FC routing service
FC-FC Routing is supported on the following platforms:
400 MP Router
4/256 SAN Director or DC SAN Backbone Director (short name, DC Director) when it is configured
with an FR4- 1 8i blade and uses chassis configuration option 5
The DC Director only supports chassis configuration option 5.
In an edge fabric that contains a mix of administrative domain (AD)-capable switches and switches that
are not aware of AD, the FC router must be connected directly to the AD-capable switch. For more
You can use SANtegrity to configure M-Series switches connecting to a B-Series router. For more
information, refer to
The supported configurations are:
FC router connected to an HP nonsecured fabric.
FC router connected to an HP secured fabric.
FC router connected to a McDATA fabric configured for Open Mode 1.
FC router connected to a McDATA fabric configured for McDATA fabric mode.
FC router connected to HP secured and nonsecured fabrics with EX_Port trunking enabled.
FC router interoperating with older FC routers (XPath OS 7.4.x and Fabric OS 5.1, 5.2, and 5.3).
Fibre Channel routing concepts
Fibre Channel routing introduces the following concepts:
A backbone (BB) fabric is an intermediate network that connects one or more edge fabrics. In a SAN,
the backbone fabric consists of at least one FC router and possibly a number of Fabric OS-based Fibre
Channel switches (see
While the 400 MP Router and 4/256 SAN Director or DC Director with an FR4- 1 8i blade facilitate
communication between devices in edge fabrics with those in a backbone fabric, this is not true of the
An edge fabric is a Fibre Channel fabric with targets and initiators connected through the supported
platforms by using an EX_Port or VEX_Port.
Special types of ports, called an EX_Port and a VEX_Port, function similarly to an E_Port and VE_Port
respectively, but terminate at the switch and do not propagate fabric services or routing topology
information from one edge fabric to another. The link between an E_Port and EX_Port, or VE_Port and
VEX_Port, is called an interfabric link (IFL). You can configure multiple IFLs from a 400 MP Router, an
FR4- 1 8i operating in a 4/256 SAN Director or DC Director using chassis configuration option 5, from
additional HP routers, or from all three. These are referred to as "an FC router" throughout this chapter
and unless specified, any FC router can be used.
FC-FC Routing Services support EX_Ports and VEX_Ports connected to the same edge fabrics (see
