远距离存储级灾备方案-行动派

现状及需求分析

需求
客户要做存储级的灾备，现已有两台IBM V7000存储，计划使用V7000存储的 FlashCopy 功能实现两个存储的远程复制功能。由于异地裸光纤部署限制条件多以及成本太高，需要提供一个基于专线的FC SAN组网解决方案，总结来说此项目需要在没有裸光纤的前提下将两个现有的异地FC SAN Fabric组成一个更大的光纤交换网。
客户现有环境
- 专线路由（网关）
  - 生产机房：xxx.xxx.xxx.xxx
  - DR机房：xxx.xxx.xxx.xxx
- SAN Fabric
  - 生产机房：4台SAN Switch，两两级联，两套SAN网络做冗余
  - DR机房：1台SAN Switch

方案设计

方案概述

本方案采用两台EMC² MP-7500B多协议SAN交换机，使用FCIP协议设备实现远距离的连接；同时不采用MP-7500B与现有的SAN Fabirc进行级联，而采用FC routing （FC路由）的方式连接，这样可以避免对现有SAN Fabirc的影响，方案整体设计示意图如下：

本方案中的相关技术术语

FCIP
FCIP的全称是Fibre Channel over Internet Protocol，是通过在IP网络的两个端点之间建立一条隧道来传输光纤通道数据，使得可以将两个距离比较远的Fibre Channel网络连接在一起，组成一个更大的存储交换网络。它的好处是无需在两地之间再部署光纤网络，就可以实现使用现有的以太网络架构进行IP协议封装FC协议传输。
FC routing
FC SAN 的路由器（ router ）成为FC routing（简称 FCR），用于了传统 FC SAN 网络的扩充能力。我们在连接两个或多个 fabrics 时 , 都必须将 fabric 的信息（例如： zone 的数据）结合；但基与 FC 到 FC 的路由（ FC-to-FC routing ）功能，我们可以不用结合 fabric 的信息，即可连接两个或多个 fabrics 。
其他术语
- ISL：Inter Switch Linke(内部交换链路)

FCIP配置

1. 实验环境说明

设备：两台EMC² MP-7500，一台三层网络交换机Cisco 3560G模拟客户的网络环境

生产机房的MP-7500B设备
- Fabric OS：6.4.1a
- Switchname：Production
- ge0：
  IP：192.168.1.10
  NETMASK：255.255.255.0
  MTU：1500
- ge1：
  IP：192.168.1.11
  NETMASK：255.255.255.0
  MTU：1500
DR机房的MP-7500B设备
- Fabric OS：6.4.1a
- Switchname：DR
- ge0
  - IP：192.168.2.10
  - NETMASK：255.255.255.0
  - MTU：1500
- ge1
  - IP：192.168.2.11
  - NETMASK：255.255.255.0
  - MTU：1500
网络环境：一台Cisco 3560G设备
- Cisco的三层交换机用两个VLAN实现不同网段的通讯
  - VLAN1：8~11口，192.168.1.1，接生产机房的MP-7500
  - VLAN2：12~15口，192.168.2.1，接DR机房的MP-7500
- 网络环境中必须关闭防火墙或开启以下端口
  - FCIP traffic (TCP port 3225) and IPSec traffic(UDP port 500)
  - TCP port 3226
  - 如果需要启动ipperf session时，需开启3227的TCP端口(默认端口，可指定其他端口）

2. 配置生产机房的MP-7500B

修改switchDomain ID
这个算是级联，需要修改switchDomain ID，本台不修改，修改DR的MP-7500B
GE port网络配置
- IP信息配置命令格式：
  portcfg ipif <port> create <IP_Address> <Subnetmask> <MTU>
- 到达192.168.2. 0/24(DR机房网段)需要创建静态route到192.168.1.1(本地网关)，直连不需要配置
- 命令格式：portcfg iproute <port> create <host_subnet> <Subnetmask> <Gateway>
- 注意：必须在以太网环境中开通3225和3227端口或关闭防火墙。
- ge0和ge1端口配置log记录

produce:admin> portshow ipif all      //查看所有端口的ip信息

FC routing配置

1. 分配backbone Fabric IDs

如果您的配置只有一个backbone fabric，则不需要分配骨干网组织ID，因为此情况下的FID缺省值为128(如果虚拟网桥被禁用，缺省的FID为1)
一个backbone fabric中的所有交换机必须具有相同的FID
两个不同的backbones连接到同一个edge fabric时，FID不同，但是edge fabric ID应该相同。

设定生产机房MP-7500B的Fabric ID（FID）

Production:admin> switchdisable 
Production:admin> fosconfig --disable fcr
FC Routing service is disabled
Production:admin> fcrconfigure 
FC Router parameter set. <cr> to skip a parameter
Please make sure new Backbone Fabric ID does not conflict with any configured EX-Port's Fabric ID
Backbone fabric ID: (1-128)[2] 3
Production:admin> fosconfig --enable fcr        //开启FC routing服务
FC Routing service will be enabled the next time switch is enabled   //提示下次enable交换机是开启fcr
Production:admin> switchenable      //enable交换机
Production:admin> 
Production:admin> fosconfig --show    //验证下fcr是否开启
FC Routing service:     enabled

iSNS client service:        Service not supported on this Platform
Virtual Fabric:         Service not supported on this Platform
Ethernet Switch Service:    Service not supported on this Platform

设定DR机房MP-7500B的Fabric ID（FID）
一个backbone fabric中的所有交换机必须具有相同的FID

DR:admin> switchdisable 
DR:admin> fosconfig --disable fcr
FC Routing service is disabled
DR:admin> fcrconfigure 
FC Router parameter set. <cr> to skip a parameter
Please make sure new Backbone Fabric ID does not conflict with any configured EX-Port's Fabric ID
Backbone fabric ID: (1-128)[2] 3
DR:admin> fosconfig --enable fcr      
FC Routing service will be enabled the next time switch is enabled  
DR:admin> switchenable

2. 为edge和backbone连接配置IFL

在生产机房MP-7500B设置

Production:admin> portcfgexport 
Usage: portcfgexport [SlotNumber/]PortNumber
                [-a 1-enable 2-disable] [-f fid(1..128)]
                [-r r_a_tov] [-e e_d_tov] [-d domain]
                [-p 0-native 1-core 2-extended edge]
                [-m 0-Brocade 1-Open 2-McDATA Fabric 3-McDATA Fabric Legacy]
                [-t 1-Enable 2-Disable]
Production:admin> portcfgexport 2 -a 1 -f 3
Port needs to be disabled for configuration   //配置前必须disable对应端口
Production:admin> portdisable 2
Production:admin> portcfgexport 2 -a 1 -f 3
Fabric ID being set conflicts with local fabric ID   //不能占用本机的FID
Production:admin> portcfgexport 2 -a 1 -f 4
Production:admin> portcfgexport 2
        Port   2   info

Production:admin> fcredgeshow

------------------------------------------------------------------------
   4        2          -        OFFLINE

Production:admin> portenable 2
Production:admin> portcfgpersistentenable 2

同上配置DR机房的MP-7500B
注意不能与生产机房分配的FID一样
分别用光纤线连接两个机房的MP-7500B与现有的SAN Fabirc

3. Lsan Zone

在生产机房的SAN Fabirc中作如下配置

Production:admin> cfgshow    //配置过程省略，只看结果
Defined configuration:
 cfg:   test    lsan_test
 zone:  lsan_test   
        DS4700_A; HP_PC
 alias: DS4700_A    
        20:14:00:a0:b8:26:11:a6
 alias: HP_PC   50:01:43:80:09:ac:63:08

Effective configuration:
 cfg:   test    
 zone:  lsan_test   
        20:14:00:a0:b8:26:11:a6
        50:01:43:80:09:ac:63:08

在DR机房的SAN Fabirc中做如下配置

DR:admin> cfgshow
Defined configuration:
 cfg:   Test    lsan_test
 zone:  lsan_test   
        DS4700_A; HP_PC
 alias: DS4700_A    
        20:14:00:a0:b8:26:11:a6
 alias: HP_PC   50:01:43:80:09:ac:63:08

Effective configuration:
 cfg:   Test    
 zone:  lsan_test   
        20:14:00:a0:b8:26:11:a6
        50:01:43:80:09:ac:63:08

测试结论
- 经过路由设备的zone的名字只能以lsan_开头，配置才能有效
- 只有在两个edge Fabrics中都配置的lsan zone，才能进行通信
验证
- DS4700
