FCoE operates on top of the data link layer in the OSI model which contrasts with most other well-known protocols that may use Ethernet, such as (for a storage-related example) iSCSI, which runs on top of TCP over IP. As a consequence, FCoE is not routable at the IP layer and will not work across routed IP networks such as the Internet.
As noted above, one of the drivers behind enhancing Ethernet is to support storage traffic. While iSCSI was available, it depends on TCP/IP and there was a desire to support storage traffic at layer 2. This gave rise to the development of the FCoE protocol, which needed reliable Ethernet transport.

The Linux-IO Target (LIO) is an open-source Small Computer System Interface (SCSI) target implementation included with the Linux kernel. [1]Unlike initiators, which begin sessions, LIO functions as a target, presenting one or more Logical Unit Numbers (LUNs) to a SCSI initiator, receiving SCSI commands, and managing the input/output data transfers.
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
An Ethernet fabric is promoted for Fibre Channel over Ethernet (FCoE) and iSCSI storage traffic. Ethernet fabrics have the following characteristics: [2] Flatter: Ethernet fabrics are self-aggregating, enabling a flatter network. Intelligent: Switches in the fabric know about each other and all connected devices.
In this regard it is more comparable to Fibre Channel over Ethernet than iSCSI. With fewer protocol layers, this approach makes AoE fast and lightweight. It also makes the protocol relatively easy to implement and offers linear scalability with high performance. The AoE specification is 12 pages [1] compared with iSCSI's 257 pages. [2] AoE ...
Fibre Channel over Ethernet (FCoE): A software target implementation supports NICs with DCB/DCBX capabilities, or build time options exist for supporting Emulex OneConnect FCoE CNAs (requires the Emulex OCS SDK) and Chelsio Uwire FCoE CNAs. [12] iSCSI: Will work over any IP communication method supported by ESOS (Ethernet, IPoIB).
