iSCSI, FCIP and iFCP.
The Fibre Channel protocol is a gigabit networking technology specifically developed for interconnecting servers and storage devices. Fibre Channel is based on the SCSI protocol.
iSCSI, FCIP and iFCP are storage protocols designed to use existing IP technologies, features and infrastructure:
- iSCSI encapsulate SCSI commands into TCP/IP traffic.
- FCIP encapsulate FC for transport over TCP/IP sockets. It's a tunneling protocol and it extends the FC fabric. FC services are kept intact. It relies on gateway to perform the encapsulation.
- iFCP replace lower-layer Fibre Channel transport with TCP/IP. FC transport services are being mapped to TCP/IP. This operation is realized by iFCP gateways. Once on IP, TCP/IP routing and switching can be used
