  • iSCSI
  • NAS
  • LIF

问题解答

不可以、iSCSI LUN和NAS LUN (如NFS/Cifs)应分开、原因如下:
  • NAS LUN可以在节点之间自由移动、也可以属于故障转移组、故障转移组用于指定在HA或端口故障转移期间将其移动到哪个节点和端口。
  • SAN lifs (iSCSI或FC)表示在SCSI启动程序和SCSI目标之间同时建立的多个路径的端点。主机的MPIO软件管理接收I/O的路径
  • SAN的故障转移方式与NAS的故障转移方式不同。SAN的故障转移机制是配置多个路径、并在主机上使用多路径(MPIO)软件来管理为其提供的多个路径。
  • 由于这种行为差异、使用iSCSI协议提供数据的以太网LUN不能同时使用NAS协议提供数据。
但是、iSCSI和NAS LIF可以使用相同的SVM以及相同的物理或VIF端口、但必须将它们配置为单独的LIF。
