iSCSI Connectivity

In computing, Internet Small Computer Systems Interface (iSCSI) is an IP-based storage networking standard for linking data storage systems.

By carrying SCSI commands over IP networks, iSCSI is used to access remote block devices in the SAN, providing hosts with the illusion of locally attached devices.

A single discoverable entity on the iSCSI SAN, such as an initiator or a target, represents an iSCSI node.

Each iSCSI node can be identified in a number of ways, such as by:

• IP address

  Each iSCSI node can have an IP address associated with it so that routing and switching equipment on your network can establish the connection between the server and storage. This address is just like the IP address that you assign to your computer to get access to your company's network or the Internet.

• iSCSI name

  A worldwide unique name for identifying the node. iSCSI uses the iSCSI Qualified Name (IQN) and Extended Unique Identifier (EUI).

  By default, SUSE generates unique iSCSI names for your iSCSI initiators, for example, iqn.1996-04.de.suse:01:1fe172a469b1. Usually, you do not have to change the default value, but if you do, make sure that the new iSCSI name you enter is worldwide unique.
