How do FCIP and ISCSi differ?

A.
ISCSI is a mechanism for adding mid-level servers to a SAN, where FCIP is a means to
connect SAN to SAN.

B.
ISCSI encapsulates a SCSI I/O request in a TCP/IP packet and routes it across an IP network.
FCIP encapsulates native fibre channel into an IP
packet and tunnels it across an IP network.

C.
ISCSi encapsulates native fibre channel into an IP packet and tunnels it across an IP network.
FCIP encapsulates a SCSI I/O request in a TCP/IP
packet and routes it across an IP network.

D.
ISCSi is a fibre channel replacement protocol and FCIP bridges the gap created when a
customer migrates from pure fibre channel to ISCSi.
