Abstract

摘要

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.

Internet小型计算机系统接口(iSCSI)是一种SCSI传输协议,它将SCSI系列协议映射到TCP/IP。本文档定义了一种附加的iSCSI节点名称类型格式,以便能够使用由国际信息技术标准委员会(INCITS)T11-光纤通道(FC)协议定义并由串行连接SCSI(SAS)使用的“网络地址管理机构”(NAA)全球命名格式。本文档更新了RFC 3720。

1. Introduction
1. 介绍

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.

本文档讨论了添加NAA类型格式作为iSCSI节点命名格式的动机,并根据iSCSI命名约定定义了此格式[RFC3720]。定义此格式将使同时包含iSCSI端口和SAS端口的SCSI存储设备能够使用相同的基于NAA的SCSI设备名称。

2. Background
2. 出身背景

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.

许多网络传输目前为SCSI协议提供端口抽象。这些传输都包含某种形式的全球唯一名称构造格式。下表总结了当前协议及其命名格式。

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 the most commonly used identifier format for SCSI transports.

INCITS T11帧和信令规范[FC-FS]定义了一种称为网络地址授权(NAA)格式的格式,用于构造使用各种标识符注册授权的全球唯一标识符。此标识符格式由光纤通道和SAS SCSI传输协议使用。由于目前大多数现有的网络SCSI端口是FC或SAS,NAA格式是SCSI传输最常用的标识符格式。

3. Motivation
3. 动机

If iSCSI included a naming format that allowed direct representation of an NAA-format name, it would facilitate construction of a target device name that translates easily across multiple namespaces for a SCSI storage device containing ports served by different transports.

如果iSCSI包含一种允许直接表示NAA格式名称的命名格式,那么它将有助于构建目标设备名称,该名称可以轻松地跨多个名称空间转换为包含由不同传输服务的端口的SCSI存储设备的名称。

This document defines an NAA type iSCSI naming format so that one NAA identifier can be assigned as the basis for the SCSI device name for a SCSI target with both SAS ports and iSCSI ports.

本文档定义了NAA类型的iSCSI命名格式,以便可以为同时具有SAS端口和iSCSI端口的SCSI目标分配一个NAA标识符作为SCSI设备名称的基础。

INCITS T10 SCSI has defined a string format SCSI target device name in [SPC3] that is reported in the VPD page 83 device identifier page. [SAM3] specifies that a SCSI device shall have no more than one (i.e., zero or one) SCSI device name in the SCSI name string format regardless of the number of SCSI transport protocols supported by the SCSI device. Adding the INCITS T11-defined NAA format as a defined type for iSCSI device names would make the iSCSI device naming format more consistent across all current SCSI networked transports that define an NAA format SCSI device name. This would facilitate the creation of SCSI device names that are transport-independent. It would also contribute to the creation of SCSI Logical Unit (LU) names based on this SCSI device name.

INCITS T10 SCSI在[SPC3]中定义了字符串格式的SCSI目标设备名称,该名称在VPD第83页设备标识符页中报告。[SAM3]指定一个SCSI设备的SCSI名称字符串格式不得超过一个(即零个或一个)SCSI设备名称,无论SCSI设备支持的SCSI传输协议的数量如何。将INCITS T11定义的NAA格式添加为iSCSI设备名称的定义类型将使iSCSI设备命名格式在定义NAA格式SCSI设备名称的所有当前SCSI网络传输中更加一致。这将有助于创建独立于传输的SCSI设备名称。它还将有助于基于此SCSI设备名称创建SCSI逻辑单元(LU)名称。

4. iSCSI NAA Name Structure
4. iSCSI NAA名称结构

This document defines an additional iSCSI name type:

本文档定义了另一种iSCSI名称类型:

type "naa." - the remainder of the string is an INCITS T11 defined Network Address Authority identifier in ASCII-encoded hexadecimal.

键入“naa”-字符串的其余部分是INCITS T11定义的网络地址授权标识符,采用ASCII编码的十六进制。

4.1. Type "naa." - Network Address Authority
4.1. 键入“naa”-网络地址授权

[FC-FS] defines a format for constructing globally unique identifiers, referred to as the Network Address Authority (NAA) format.

[FC-FS]定义了一种用于构造全局唯一标识符的格式,称为网络地址授权(NAA)格式。

The iSCSI NAA naming format is "naa.", followed by an NAA identifier represented in ASCII-encoded hexadecimal digits.

iSCSI NAA命名格式为“NAA”,后跟以ASCII编码的十六进制数字表示的NAA标识符。

An example of an iSCSI name with a 64-bit NAA value follows:

具有64位NAA值的iSCSI名称示例如下:

         Type  NAA identifier (ASCII-encoded hexadecimal)
         +--++--------------+
         |  ||              |
        
         Type  NAA identifier (ASCII-encoded hexadecimal)
         +--++--------------+
         |  ||              |
        

naa.52004567BA64678D

naa.52004567BA64678D

An example of an iSCSI name with a 128-bit NAA value follows:

具有128位NAA值的iSCSI名称示例如下:

         Type  NAA identifier (ASCII-encoded hexadecimal)
         +--++------------------------------+
         |  ||                              |
        
         Type  NAA identifier (ASCII-encoded hexadecimal)
         +--++------------------------------+
         |  ||                              |
        
         naa.62004567BA64678D0123456789ABCDEF
        
         naa.62004567BA64678D0123456789ABCDEF
        

The iSCSI NAA naming format might be used in an implementation when the infrastructure for generating NAA worldwide unique names is already in place because the device contains both SAS and iSCSI SCSI ports.

当用于生成NAA全球唯一名称的基础结构已经就绪时,可以在实现中使用iSCSI NAA命名格式,因为该设备同时包含SAS和iSCSI SCSI端口。

The NAA identifier formatted in an ASCII-hexadecimal representation has a maximum size of 32 characters (128 bit NAA format). As a result, there is no issue with this naming format exceeding the maximum size for iSCSI node names.

以ASCII十六进制表示形式格式化的NAA标识符的最大大小为32个字符(128位NAA格式)。因此,此命名格式不会超过iSCSI节点名称的最大大小。
