Internet Small Computer Systems Interface
RFC 3720, “Internet Small Computer Systems Interface”, is a Proposed Standard document published in April 2004 by J. Satran, K. Meth, C. Sapuntzakis, M. Chadalapaka, E. Zeidner. It has since been updated by RFC 3980, RFC 4850, RFC 5048, RFC 7146. It has been obsoleted by RFC 7143 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes a transport protocol for Internet Small Computer Systems Interface (iSCSI) that works on top of TCP. The iSCSI protocol aims to be fully compliant with the standardized SCSI architecture model. SCSI is a popular family of protocols that enable systems to communicate with I/O devices, especially storage devices. SCSI protocols are request/response application protocols with a common standardized architecture model and basic command set, as well as standardized command sets for different device classes (disks, tapes, media-changers etc.). As system interconnects move from the classical bus structure to a network structure, SCSI has to be mapped to network transport protocols. IP networks now meet the performance requirements of fast system interconnects and as such are good candidates to "carry" SCSI. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
