Explanation

IP SAN Protocol: FCIP FC SAN provides a high-performance infrastructure for localized data movement. Organizations are now looking for ways to transport data over a long distance between their disparate SANs at multiple geographic locations. One of the best ways to achieve this goal is to interconnect geographically dispersed SANs through reliable, high-speed links. This approach involves transporting the FC block data over the IP infrastructure. FCIP is a tunneling protocol that enables distributed FC SAN islands to be interconnected over the existing IP-based networks. FCIP is a protocol in which FCIP entity such as FCIP gateway is used to tunnel FC fabrics through an IP network. In FCIP FC frames are encapsulated onto the IP payload. An FCIP implementation is capable to merge interconnected fabrics into a single fabric. Frequently, only a small subset of nodes at either end requires connectivity across fabrics. Thus, the majority of FCIP implementations today use switch-specific features such as IVR (Inter- VSAN Routing) or FCRS (Fibre Channel Routing Services) to create a tunnel. In this manner, traffic may be routed between specific nodes without actually merging the fabrics. The FCIP standard has rapidly gained acceptance as a manageable, cost-effective way to blend the best of the two worlds: FC SAN and the proven, widely deployed IP infrastructure. As a result, organizations now have a better way to store, protect, and move their data by leveraging investments in their existing IP infrastructure. FCIP is extensively used in disaster recovery implementations in which data is duplicated to the storage located at a remote site.
