The iSCSI resource enables you to create and manage iSCSI intiators, iSNS servers and the iSCSI domain. iSCSI is an IP storage networking standard that links storage systems. By forwarding iSCSI commands over the network, iSCSI enables data transfer both over local area and wide area networks.
An iSCSI target is a node or instance running on an iSCSI server. Typically, the target is a disk drive. Targets act as destinations to which management settings and information is sent by an iSCSI initiator. An iSCSI logical unit, or LUN, is a logical representation of a physical device on the iSCSI target, identified by the LUN number. An iSCSI initiator establishes a connection with the LUN through a series of sessions with the target.
