簡介

Cisco的iSCSI驅動程式位於伺服器上，是iSCSI解決方案的關鍵元件。這些iSCSI驅動程式會攔截SCSI命令，將其封裝到IP資料包中，然後將其重定向到Cisco SN 5420、Cisco SN 5428、Cisco SN 5428-2或Cisco MDS/IPS-8。本文檔提供了使用Microsoft Windows XP iSCSI到MDS/IPS-8的主機的配置示例。

必要條件

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

術語MDS 9000是指MDS 9000系列（MDS 9506、MDS 9509或MDS 9216）中的任何光纖通道(FC)交換機產品。IPS刀片指的是IP儲存服務模組。

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

IP儲存模組為IP主機提供對光纖通道(FC)儲存裝置的訪問。IP儲存模組是DS-X9308-SMP。它提供透明的SCSI路由。使用iSCSI協定的IP主機可以透明地訪問FC網路上的SCSI(FCP)目標。IP主機通過TCP/IP連線將封裝在iSCSI協定資料單元(PDU)中的SCSI命令傳送到MDS 9000 IPS埠。在IP儲存模組上，連線是以正確配置的千兆乙太網(GE)介面的形式提供的。IP儲存模組使您能夠建立虛擬iSCSI目標並將它們對映到FC SAN中可用的物理FC目標。它向IP主機呈現FC目標，就像物理目標在本地連線一樣。

每個需要通過IP儲存模組訪問儲存的iSCSI主機都需要安裝相容的iSCSI驅動程式。藉由iSCSI協定，iSCSI驅動程式允許iSCSI主機通過IP網路傳輸SCSI請求和響應。從主機作業系統的角度來看，iSCSI驅動程式似乎是SCSI傳輸驅動程式，類似於主機中外圍通道的FC驅動程式。從儲存裝置的角度來看，每個IP主機都顯示為FC主機。

將SCSI從IP主機路由到FC儲存裝置包含以下主要操作：

通過IP網路在主機和IP儲存模組之間傳輸iSCSI請求和響應。
在IP網路上的主機和FC儲存裝置之間路由SCSI請求和響應（將iSCSI轉換為FCP，反之亦然）。這由IP儲存模組執行。
在IP儲存模組和FC儲存裝置之間傳輸FCP請求或響應。

預設情況下，IP儲存模組不會將FC目標匯入iSCSI。在IP儲存模組使FC目標可用於iSCSI啟動器之前，必須配置動態或靜態對映。當兩者都配置時，靜態對映的FC目標具有已配置的名稱。在此配置中，將提供靜態對映的示例。

使用動態對映時，每次iSCSI主機連線到IP儲存模組時，都會建立一個新的FC N埠，並為此N埠分配的nWWN和pWWN可能不同。如果需要在iSCSI主機每次連線到IP儲存模組時獲得相同的nWWN和pWWN ，請使用靜態對映方法。可以在IP儲存模組上使用靜態對映來訪問智慧FC儲存陣列，這些儲存陣列具有基於啟動器的pWWN和/或nWWN的訪問控制以及邏輯單元號(LUN)對映/遮蔽配置。

如果指定將在其上通告靜態對映的IP儲存埠的清單，並指定允許訪問它的iSCSI啟動器節點名稱的清單，則可以控制對每個靜態對映的iSCSI目標的訪問。基於FC分割槽的訪問控制和基於iSCSI的訪問控制是為iSCSI提供訪問控制的兩種機制。這兩種方法可以同時使用。

iSCSI發現發生在iSCSI主機為所有iSCSI目標建立iSCSI發現會話和查詢時。IP儲存模組僅返回iSCSI主機根據訪問控制策略允許訪問的iSCSI目標清單。

iSCSI會話建立在IP主機發起iSCSI會話時進行。IP儲存模組驗證指定的iSCSI目標（在會話登入請求中）是否為靜態對映目標，如果為true，則驗證是否允許IP主機的iSCSI節點名稱訪問目標。如果IP主機沒有存取許可權，則其登入會遭到拒絕。

IP儲存模組然後為該IP主機建立一個FC虛擬N埠（N埠可能已經存在），並且對IP主機訪問的FC目標pWWN的FCID執行FC名稱伺服器查詢。它使用IP主機虛擬N埠的pWWN作為名稱伺服器查詢的請求者。因此，名稱伺服器對pWWN執行區域強制查詢並響應查詢。如果名稱伺服器返回FCID，則接受iSCSI會話。否則，登入請求將被拒絕。
