Simple definition
An iSCSI target exposes block storage devices or logical units to authorized initiators over an IP network.
Purpose and use
An iSCSI target exposes block-storage units to authorized initiators.
How does it work?
It accepts sessions on network portals and applies configured unit presentation and access controls.
Example and verification
Verify initiator-to-volume mappings and expected visibility from each host.
Points to watch
Session authentication does not necessarily encrypt data. Assess transport protection and authorization separately.
In short
The target exposes blocks and must restrict them to the intended initiators.
