The Internet Small Computer Systems Interface (iSCSI) is a SCSI mass storage transport that operates between the

Transport Control Protocol (TCP) and the SCSI Protocol Layers. The iSCSI protocol is defined in RFC 3720

[iSCSI], which was finalized by the Internet Engineering Task Force (IETF) in April 2004. A TCP/IP connection

ties the iSCSI initiator and target session components together. Network portals identified by their IP address and

TCP port numbers define the endpoints of a connection. iSCSI is, by nature, a lossless storage network because

inherent in the iSCSI design is recovery from dropped packets on over-subscribed, heavy network traffic patterns.

iSCSI relies on TCP/IP (or SCTP) for the retransmission of dropped Ethernet frames.
