客户端配置（Initiator）

「Debian as an iSCSI Initiator」

服务端配置（Target）

「Debian as a Target (using IET’s iscsitarget)」
「Debian as a Target (using the LIO Target)」

在计算中，Linux-IO（LIO）Target是SCSI Target的开源实现，已成为Linux内核中的标准实现。

一个竞争通用SCSI Target模块是SCST，也是用于Linux的。对于提供Linux iSCSI Target的较窄目的，较旧的IET和STGT模块也享有行业支持。

iSCSI vs. SCSI

「Difference between SCSI and iSCSI」

SCSI is a layer 2 deterministic channel protocol. It’s initials stand for “Small Computer Systems Interface.” It is a standard protocol for computer systems to connect to storage systems. SCSI protocol runs on Fibre Channel (called fibre channel protocol or FCP), Infiniband, and layer 2 Ethernet.

ANSI, SNIA, and the IEEE working groups mapped the SCSI protocol to TCP/IP to enable the SCSI protocol to work on layer 3 TCP/IP Ethernet. This standard is called iSCSI.

iSCSI is the SCSI protocol mapped to TCP/IP and run over standard Ethernet technologies.
