简介

本文提供一个示例配置，关于MDS基本的TCP/IP光纤信道 (FCIP)多层导向交换机(MDS)。

此配置示例与 SAN-OS 的 1.2 和 1.3 版本有关。SAN-OS 2.0 版本中的一些参数发生了变化。请参考 2.0 SAN-OS 配置指南和版本说明。

FCIP描述了在基于IP的光纤信道(FC)存储区域网络（SAN）岛实现互连的机制，以便在单个FC光组织中组成统一的SAN。FCIP依靠基于IP的网络服务，在通过局域网、城域网或广域网的SAN岛之间提供连连通性。

由 FCIP 连接的光纤通道 SAN

basic_fcip_mds-a.gif

FCIP 在端口 3225 上使用传输控制协议 (TCP) 作为一种网络层传输技术。

先决条件

要求

IP骨干网必须是可运行的，并提供所需的带宽，以支持在FCIP链路上 - 可能是第二层(L2)拓扑或第三层(L3)拓扑 - 运行的应用。如果必须配置L3、中间路由器或多层交换机来正确转发FCIP隧道的IP数据流源IP地址和目的地IP地址。如果在FCIP对等体路径上的任何网络设备中强制执行服务质量（QoS）或流量整形，那么在MDS FCIP配置文件上配置任何TCP的相关参数和功能之前，应参考管理IP结构的网络管理器，以了解必要的详细资料。

使用的组件

本文档中的信息基于下列软件和硬件版本：

  • 具备 IP Storage (IPS) 服务模块 (DS-X9308-SMIP) 1.2.(2a) 运行版本的 MDS 9509

  • 具备 IPS 服务模块 (DS-X9308-SMIP) 1.2.(2a) 运行版本的 MDS 9509

  • 带有Emulex LP9K HBA的Win2003服务器(HPQ Pro-Liant-P4)

  • IBM 存储阵列 (ESS-2105-F20)

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

规则

有关文件规则的更多信息请参见“ Cisco技术提示规则”。

背景信息

FCIP 包括以下规格：

ANSI T11

  1. FC-SW-2描述FC交换机的操作和交互作用包括E_Port和结构操作。

  2. FC-BB-2是适合通过TCP网络主干的FC交换网络扩展的映射，它同时还定义了支持E_端口 和B_端口的参考模型。

IETF IPS 工作组

  1. TCP的FC包括在一个IP网络上传输FC帧的TCP/IP要求。

  2. FC 帧封装可定义普通的光纤封装格式。

在2个SAN交换机或整个FCIP上的结构互连被称为FCIP链路，它能包含一条或多条TCP连接。FCIP链路的每个结尾与虚拟E端口(VE_端口)或B_端口连接，这取决于实施情况。FC-BB 和 FC-BB-2 可描述两种方法之间的区别。IP业务模块(DS-X9308-SMIP)支持两种模式，但默认为VE_Port，如果所有相关对等体都是DS-X9308-SMIP模块，VE_Port也是推荐运行的模式。MDS平台上的VE_Port功能还支持TE 端口功能，此功能使它能够在一个FCIP实例上支持来自多个VSAN的中继数据流。

配置

在MDS上，您需要用适于两个平台的IPS配置指南进行自我熟悉。手册的最新版本为配置 IP 存储。

网络图

本文档使用下图所示的网络设置。

basic_fcip_mds-b.gif

此图表显示了一个典型的实验室设置，其中没有其它的网络设备在两台MDS交换机的两个千兆以太网(GE)接口之间连接。这是 FCIP安装的MDS的最简单形式，一般用于用户实验室，以验证基本功能。在 VSAN 600 中，Emulex LightPulse 9000 HBA 将 Windows 2003 服务器连接至 MDS 9509 (Bison)，将 IBM 存储阵列连接至 MDS9216 (Canterbury)，在其中可配置 Windows 2003 服务器的 LUN。

Agilent SAN测试设备用作仿真器，用两个装置安装VSAN 601，并且生成大量的FC-2非-FCP后台流量。增加外围设备使配置更可实现，并可在两台参与交换机的被分配名称服务器中拥有大量条目。本文不关注端到端连通性，不包括服务器或存储阵列的截屏画面。外围设备不了解FCIP，并且它的运行就好象两个MDS之间的EISL链路在一条正常FC链路上运行一样。

配置

!--- Note that Gig4/1 in the default state is configured with an MTU size of !--- 1500 bytes, if the network topology allows for larger end-to-end frame !--- sizes known as jumbo frames. !--- The default value may be changed to a higher value. A good value is !--- 3000 bytes, because this would avoid the fragmentation of full 2048 FC !--- frames into multiple TCP segments. Not all networking equipment can handle !--- jumbo frames, so the default value of 1500 bytes is a conservative !--- approach to avoid connectivity issues while bringing up the FCIP tunnel.
