Scenario 9: Multi-Hop FCoE using Multi-FCoE networks and
ports with HP 5900 Series switch in NPV mode connected to a
Nexus 5xxx Series switches (using a FCoE Port Channel)
In this Multi-hop FCoE scenario, two Converged Shared Uplink Sets using a single or multiple uplink ports and carrying a
single FCoE network and multiple standard Ethernet networks are created between Virtual Connect modules and HP
5900 switches. The FCoE traffic is then extended farther to Nexus 5xxx Series switches that are connected to a FC/FCoE-
based storage target.

Benefits
This Multi-Hop FCoE scenario extends convergence beyond the Top of Rack switches up to a Nexus infrastructure
without requiring any Fibre Channel SAN switch investments.
With this scenario having HP 5900AF switches with no Fibre Channel port is not anymore a limitation as it uses Ethernet
to transport the Fibre Channel data.
