Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

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.
