End to End FCoE using FC ISLs

DRAFT: BROCADE CONFIDENTIAL
The following diagram shows a deployment scenario where FCoE initiators are connected to FCoE
and FC targets across multiple hops of FC ISLs.
FIGURE 3 Deploying FCoE across multiple hops of FC ISLs
FCoE Logical Port Numbering
A total of 24 FCoE logical ports on FCOE10-24 belong to 6 FCoE port groups. The port number
range is 0 through 23 and these belong to 6 FCoE port groups ranging from 0 through 3, 4 through
7, 8 through 11, 12 through 15, 16 through 19, and 20 through 23. For example, the FCoE ports on
a 24 port blade in the 4th slot is 4/0 through 4/23.
NOTE
This grouping is relevant only for bridging bandwidth considerations. A group of four ports that is
arranged in a bank has 10Gb of bridging bandwidth.
FCoE port-to-front end TenGigabit port mapping
Each of the FCoE logical ports in VF port mode is mapped to a corresponding front end TenGigabit
port such that the FCoE FLOGI received through the TenGigabit port is mapped and handled at the
corresponding FCoE logical port.
