iSCSI overview

Internet SCSI (iSCSI) is defined in IETF RFC 3720. It allows SCSI block I/O
protocols (commands, sequences and attributes) to be sent over a network using
the TCP/IP protocol. This is similar to the way SCSI commands are already
mapped to Fibre Channel, parallel SCSI, and SSA media. Do not confuse this
with the SCSI cabling transport mechanism. We are talking about protocols.

This chapter provides a high level overview of iSCSI.
