No you can’t iSCSI over Ethernet and Fibre Channel are completely different network protocols. It is possible to bridge the two together so servers with iSCSI initiators can access disk arrays or tape libraries with fibre channel connections but that’s not a simple, or seamless, task.

    While FC and iSCSI can't be on the same network since they are different protocols and work on different media, the most in-thing thesedays is convergence of SAN & NW traffic in Datacenters using Fibre Channel over Ethernet (FCoE). This is an emerging technology. With FCoE, network (IP) and storage (SAN) data traffic can be consolidated using a single network switch. This consolidation can: 1. reduce the number of network interface cards required to connect to disparate storage and IP networks on hosts (particularly useful in Blade servers and virtualized servers). 2. reduce the number of cables and switches in Datacenter 3. reduce power and cooling costs (the buzzword thesedays). While it's a costly technology at present with very few commercial implementations, it is all set to revolutionize the Datacenters in couple of years!
