FCIP mechanisms

FCIP gateways encapsulate Fibre Channel frames into IP packets and transmit them through a tunnel
in an existing IP network infrastructure. The IP tunnel is a dedicated link that transmits the Fibre Channel
data stream over the IP network. On the receiving end, the FCIP gateway extracts the original Fibre
Channel frames from the received IP packets and then retransmits them to the destination Fibre Channel
node. The gateways also handle IP-level error recovery.
NOTE:
You must use the same gateway model at both ends to ensure interoperability.
To connect to FCIP gateways, B-series and M-series switches connect through an E_Port, while C-series
switches use plug-in modules.

FCIP link configurations

Using FCIP, you can configure the SAN ISL through a single link, dual links, or shared links.

FCIP single-link configuration

The simplest FCIP configuration comprises one link

FCIP dual-link configuration

A dual-link configuration provides redundancy
handles all data replication. For enhanced fault tolerance, you can use two IP providers.
