Introduction to fiber channel: Comparison of FCIP and iSCSI

In addition to FCIP, another method is iSCSI, which converts user requests into SCSI code and encapsulates data into the IP package for transmission over Ethernet. To connect a geographically dispersed SAN, the FCIP Protocol can only be used for Fiber Channel Technology connections. In contrast, iSCSI can run on an existing Ethernet. SAN connections, such as FCIP and iSCSI protocols, can provide higher performance, validity, and fault tolerance based on point-to-point connections of traditional data storage systems. Many vendors, including Cisco, Nortel and Lucent, have introduced FCIP-based products such as switches and routers ). An Internet Fiber Channel Protocol (iFCP) hybrid technology is a variant of the FCIP protocol used to move data transmitted over an IP network using the iSCSI protocol.
