  • Page 39: Understanding Chap Authentication

    Understanding CHAP Authentication What Is CHAP Challenge Handshake Authentication Protocol (CHAP) is an optional iSCSI authentication method where the storage array (target) authenticates iSCSI initiators on the host server. Two types of CHAP are supported: • Target CHAP • Mutual CHAP Target CHAP In target CHAP, the storage array authenticates all requests for access issued by the iSCSI initiator(s) on the host server using a CHAP secret.
