You can connect hosts to both controllers in an HA pair. This connection is achieved using host FCoE initiators (CNAs) through FCoE switches to FCoE and FC mixed target ports.
The FCoE target adapter is also called a unified target adapter or UTA. Like the CNA in a host, the UTA supports both FCoE and regular Ethernet traffic.
You can have multiple FCoE and FC switches in the path between the initiator and target, up to the maximum hop count limit. To connect FCoE switches to each other, the switches must run a firmware version that supports Ethernet ISLs.
