Cisco的iSCSI驱动器(驻留在服务器上)是iSCSI 解决方案的关键组件。这些iSCSI驱动程序会拦截SCSI命令,将其封装到IP数据包中,然后将其重定向到Cisco SN 5420、Cisco SN 5428-2或Cisco MDS/IPS-8。本文档提供了使用Microsoft Windows XP i的主机的示例配置SCSI到MDS/IPS-8。
在尝试此配置前,请保证您符合这些要求:
在MDS 9000上创建iSCSI配置之前,需要安装与运行Microsoft Windows XP的PC兼容的iSCSI驱动程序。适用于Windows 2000/XP/2003的Cisco iSCSI驱动程序的最新版本可在Cisco.com的Cisco iSCSI驱动程序(仅限注册客户)页中找到。文件名是Win2k的Cisco iSCSI驱动程序版本号,可在此页的表中找到。

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。
术语MDS 9000是指MDS 9000系列(MDS 9506、MDS 9509或MDS 9216)中的任何光纤通道(FC)交换机产品。IPS刀片是指IP存储服务模块。
有关文档规则的详细信息,请参阅 Cisco 技术提示规则。
IP存储模块提供IP主机对光纤通道(FC)存储设备的访问。IP存储模块是DS-X9308-SMIP。它提供透明SCSI路由。使用iSCSI协议的IP主机可以透明地访问FC网络上的SCSI(FCP)目标。IP主机通过TCP/IP连接将封装在iSCSI协议数据单元(PDU)中的SCSI命令发送到MDS 9000 IPS端口。在IP存储模块上,以正确配置的千兆以太网(GE)接口形式提供连接。IP存储模块使您能够创建虚拟iSCSI目标,并将它们映射到FC SAN中可用的物理FC目标。它将FC目标呈现给IP主机,就像物理目标是本地连接的一样。
需要通过IP存储模块访问存储的每台iSCSI主机都需要安装兼容的iSCSI驱动程序。使用iSCSI协议, iSCSI驱动程序允许iSCSI主机通过IP网络传输SCSI请求和响应。从主机操作系统的角度, iSCSI驱动看来是SCSI运输驱动程序,与主机中一条外围通道的FC驱动程序相似。从存储设备的角度,每台IP主机出现为一台FC主机。
将SCSI从IP主机路由到FC存储设备包括以下主要操作:
在主机和IP存储模块之间通过IP网络传输iSCSI请求和响应。
在IP网络上的主机和FC存储设备之间路由SCSI请求和响应(将iSCSI转换为FCP,反之亦然)。 这由IP存储模块执行。
在IP存储模块和FC存储设备之间传输FCP请求或响应。
默认情况下IP存储模块不导入FC目标到iSCSI。在IP存储模块使FC目标可用于iSCSI启动器之前,必须配置动态或静态映射。当两个都被配置后,静态被映射的FC目标有一个配置的名称。在此配置中,提供了静态映射示例。
使用动态映射时,每次iSCSI主机连接到IP存储模块时,都会创建一个新的FC N端口,为此N端口分配的nWWN和pWWN可能不同。如果每次iSCSI主机连接到IP存储模块时需要获取相同的nWWN和pWWN,请使用静态映射方法。静态映射可用于IP存储模块,以访问具有基于启动器的pWWN和/或nWWN的访问控制和逻辑单元号(LUN)映射/掩码配置的智能FC存储阵列。
如果指定将通告每个静态映射的iSCSI目标的IP存储端口列表,并指定允许访问该端口的iSCSI启动器节点名称列表,则可以控制对每个静态映射的iSCSI目标的访问。FC基于分区的访问控制和基于ISCSI的访问控制是访问控制可以为iSCSI提供的二个机制。可以同时使用两个方法。
iSCSI发现是指iSCSI主机为所有iSCSI目标创建iSCSI发现会话和查询时发生的。IP存储模块仅返回iSCSI主机根据访问控制策略允许访问的iSCSI目标列表。
当IP主机启动iSCSI会话时,会创建iSCSI会话。IP存储模块验证指定的iSCSI目标(在会话登录请求中)是否是静态映射目标,如果为true,则验证是否允许IP主机的iSCSI节点名称访问目标。如果IP主机没有权限,其登录被拒绝。
然后,IP存储模块为此IP主机创建FC虚拟N端口(N端口可能已存在),并对IP主机访问的FC目标pWWN的FCID执行FC名称服务器查询。它使用IP主机虚拟N端口的pwwn作为名称服务器查询的请求方。因此,名称服务器执行的一次强制的pwwn区域查询并且回应查询。如果名称服务器返回FCID,则接受iSCSI会话。否则,登录请求被拒绝。
