1 1 Using the FC-FC routing service
The FC-FC (Fibre Channel) Routing Service provides Fibre Channel routing between two or more fabrics
without merging those fabrics. The FC-FC Routing Service can be simultaneously used as a Fibre Channel
router and for SAN extension over wide area networks (WANs) using FCIP.
The Fibre Channel Routing also supports interoperability with McDATA E/OS v7.x and 8.x. For more
information about McDATA interoperability support, see
on page 228.

Supported platforms

FC-FC Routing is supported on the following platforms:
• HP StorageWorks B-Series MP Router blade
• HP StorageWorks 400 MP Router
• 4/256 SAN Director when it is configured with a B-Series MP Router blade and uses chassis
configuration option 5

Fibre Channel routing concepts

Fibre Channel routing introduces the following concepts:
• Logical Storage Area Networks (LSANs)
An LSAN is defined by zones in two or more edge or backbone fabrics that contain the same device(s).
You can create LSANs that can span fabrics. These LSANs enable Fibre Channel zones to cross
physical SAN boundaries without merging the fabrics while maintaining the access controls of zones
(refer to Figure

Figure 8 shows a metaSAN with a backbone consisting of one 400 MP Router connecting hosts in Edge
Fabric 1 and 3 with storage in Edge Fabric 2 and the backbone through the use of LSANs. There are
devices shared between the backbone and Edge Fabric 1, between Edge Fabric 1 and Edge Fabric 2, and
between Edge Fabric 1 and Edge Fabric 2.
