使用FCIP的MDS到MDS基本配置
簡介
本檔案將提供使用TCP/IP的基本光纖通道(FCIP)多層次導向器交換器(MDS)到MDS的組態範例。
此示例配置與SAN-OS的1.2和1.3版本相關。SAN-OS的2.0版本中的某些引數會更改。請參考2.0 SAN-OS配置指南和發行說明。
FCIP介紹的機制允許光纖通道(FC)儲存區域網路(SAN)的孤島透過基於IP的網路互連，以在單個FC網狀架構中形成整合SAN。FCIP依靠基於IP的網路服務在區域網、都會網路或廣域網上的SAN孤島之間提供連線。
通過FCIP連線的光纖通道SAN
FCIP在連線埠3225上使用傳輸控制通訊協定(TCP)作為網路層傳輸。
必要條件
需求
IP主幹必須正常工作並提供所需的頻寬，以支援通過FCIP鏈路運行的應用程式 — 這可以是第2層(L2)或第3層(L3)拓撲。如果為L3，必須設定中間路由器或多層交換機，並將其配置為在FCIP隧道的源IP地址和目標IP地址之間正確轉發IP流量。如果在FCIP對等點之間的路徑中的任何網路裝置上強制執行服務品質(QoS)或流量調節，則應在在MDS FCIP設定檔上設定任何TCP相關引數和功能之前，徵詢管理IP基礎架構的網路管理員以取得必要的詳細資訊。
採用元件
本檔案中的資訊是根據以下軟體和硬體版本：
-
MDS 9509(含IP儲存(IPS)服務模組(DS-X9308-SMP)，執行版本1.2.(2a)
-
運行1.2.(2a)版的MDS 9216，帶IPS服務模組(DS-X9308-SMIP)
-
採用Emulex LP9K HBA的Win2003伺服器(HPQ Pro-Liant-P4)
-
IBM儲存陣列(ESS-2105-F20)
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。
慣例
如需文件慣例的詳細資訊，請參閱思科技術提示慣例。
背景資訊
FCIP由以下規範組成：
ANSI T11
-
FC-SW-2描述了FC交換機的操作和互動，包括E_Port和交換矩陣操作。
-
FC-BB-2對映屬於跨TCP網路骨幹網的FC交換網路擴展，並定義支援E_Port和B_Port的參考模型。
IETF IPS工作組
-
使用TCP的FC涵蓋通過IP網路傳輸FC幀的TCP/IP要求。
-
FC幀封裝定義了常見的光纖封裝格式。
跨FCIP的兩個SAN交換器或網狀架構之間的互連稱為FCIP連結，且可包含一個或多個的TCP連線。FCIP連結的每個端都與一虛擬E連線埠(VE_port)或B_port相關聯，視實施而定。FC-BB和FC-BB-2描述了兩種方法的區別。IP服務模組(DS-X9308-SMIP)支援這兩種模式，但預設為VE_Port，如果所有相關對等體都為DS-X9308-SMIP模組，則此模式也是建議運行的模式。MDS平台上的VE_Port功能也支援TE埠功能，這使它能夠在一個FCIP例項上中繼來自多個VSAN的流量。
設定
在MDS上，您需要熟悉兩個平台的IPS配置指南。該手冊的最新版本是配置IP儲存。
網路圖表
本文檔使用下圖所示的網路設定。
此圖顯示典型的實驗設定，其中兩個MDS交換機的兩個千兆乙太網(GE)介面之間沒有連線其他網路裝置。這是MDS FCIP安裝的最簡單形式，通常在客戶實驗中用於驗證基本功能。在VSAN 600中，Emulex LightPulse 9000 HBA將Windows 2003伺服器連線到名為Bison的MDS9509，並連線到名為Canterbury的MDS9216的IBM儲存陣列，其中配置了Windows 2003伺服器的LUN。
Agilent SAN測試裝置用作模擬器，用兩台裝置填充VSAN 601，並生成大量的FC-2非FCP後台流量。新增此外圍裝置是為了使配置更切合實際，並使兩台參與交換機的分散式名稱伺服器中有大量條目。本文檔的重點不是端到端連線，並且不包括伺服器或儲存陣列的螢幕截圖。外圍裝置不瞭解FCIP，其行為就像兩個MDS之間的EISL鏈路在正常的FC鏈路上運行。
組態
本文檔使用如下所示的配置。
