Terminology

iSCSI uses the terminology of initiator (or iSCSI client) and target (or iSCSI server). NVMe/TCP uses the terminology of host and controller respectively. iSCSI 使用的术语是启动程序（或 iSCSI 客户端）和目标程序（或 iSCSI 服务器）。NVMe/TCP 分别使用主机和控制器的术语。

Fibre Channel uses the terminology of initiator, where each host may have more than one initiator. Likewise, each storage array may have more than one target. 光纤通道使用启动程序术语，每台主机可能有多个启动程序。同样，每个存储阵列也可能有多个目标。

This book uses initiator and host interchangeably based on the context regardless of the network and protocol type. Likewise, target and storage array are used interchangeably. 本书根据上下文交替使用启动程序和主机，而不考虑网络和协议类型。同样，目标和存储阵列也可以互换使用。

Fibre Channel and FCoE Terminology

Fibre Channel and FCoE use the following additional terminology (Figure 1-13): 光纤通道和 FCoE 使用以下附加术语（图 1-13）：

Figure 1-13 Fibre Channel terminology

 N_Port: N_Port is an end device port that connects to a Fibre Channel fabric. N refers to Node. FCoE calls this VN_Port (Virtual Node Port). N_Port 是连接到光纤通道 Fabric 的终端设备端口。N 指节点。FCoE 称之为 VN_Port（虚拟节点端口）。

 F_Port: F_Port is a Switchport that connects to the end device (N_Port). F refers to Fabric. FCoE calls this VF_Port. F_Port 是连接到终端设备（N_Port）的交换端口。F 指 Fabric。FCoE 称之为 VF_Port。

 E_Port: E_Port is a Switchport that connects to other Fibre Channel switches. E refers to Expansion. FCoE calls this VE_Port (Virtual Expansion Port). E_Port 是连接其他光纤通道交换机的交换端口。E 指的是扩展。FCoE
