Abstract

   Internet Small Computer Systems Interface (iSCSI) is a SCSI transport
   protocol that maps the SCSI family of protocols onto TCP/IP.  This
   document defines an additional iSCSI node name type format to enable
   use of the "Network Address Authority" (NAA) worldwide naming format
   defined by the InterNational Committee for Information Technology
   Standards (INCITS) T11 - Fibre Channel (FC) protocols and used by
   Serial Attached SCSI (SAS).  This document updates RFC 3720.

1.  Introduction

   This document discusses the motivation for adding an NAA type format
   as an iSCSI node naming format and defines this format in accordance
   with the iSCSI naming conventions [RFC3720].  Defining this format
   will enable SCSI storage devices containing both iSCSI ports and SAS
   ports to use the same NAA-based SCSI device name.

2.  Background

   A number of networked transports currently provide port abstractions
   to the SCSI protocol.  These transports all incorporate some form of
   world-wide unique name construction format.  The following table
   summarizes the current protocols and their naming formats.

   The INCITS T11 Framing and Signaling Specification [FC-FS] defines a
   format called the Network Address Authority (NAA) format for
   constructing worldwide unique identifiers that use various identifier
   registration authorities.  This identifier format is used by the
   Fibre Channel and SAS SCSI transport protocols.  As most existing
   networked SCSI ports today are either FC or SAS, the NAA format is
