What can be used on both the initiator and the target to identify an iSCSI session?

The correct answer is the Target Portal Group. In the context of iSCSI, a session is typically identified using several parameters that include the initiator name, target portal group, and session ID. However, when it comes to identifying an iSCSI session on both the initiator and the target side, the Target Portal Group plays a crucial role.

The Target Portal Group encompasses the set of IP addresses that a target can provide accessible entry points. This means that both the initiator and target can reference the same group of portals for establishing iSCSI sessions, thereby making it a shared identifier in the process. The portals facilitate communication between the initiator and target by consolidating the available network endpoints, which simplifies the management of iSCSI connections.

Understanding the significance of the Target Portal Group is essential in iSCSI configurations because it directly affects how well the initiator can discover and connect to the target devices. This is crucial for setting up storage networking protocols effectively.

While other components like the Initiator Name and Session ID are also important for iSCSI sessions, they do not serve as common identifiers on both sides in the same manner as the Target Portal Group. The Initiator Name is unique to the initiator, and while the Session
