What is Internet Small Computer System Interface (iSCSI)?

iSCSI is a way of connecting storage devices over a network using TCP/IP. It can be used over a local area network (LAN), a wide area network (WAN), or the Internet.

iSCSI devices are disks, tapes, CDs, and other storage devices on another networked computer that you can connect to. Sometimes these storage devices are part of a network called a storage area network (SAN).

In the relationship between your computer and the storage device, your computer is called an initiator because it initiates the connection to the device, which is called a target.
