Figure 13 Example of authentication of hosts (iSCSI environments)

In Figure 13, iSCSI target 1 performs authentication of hosts, but iSCSI target 2 does not.

Host A's user information is registered on iSCSI target 1, and the authentication setting is enabled.

Therefore, if authentication of the host succeeds, Host A can connect to the array (or processing goes to

the authentication of the iSCSI target). As a precondition of successful authentication, conﬁgure Host A

for authentication by iSCSI targets with CHAP.

Host B's user information is also registered on iSCSI target 1, but the authentication setting is disabled.

Therefore, Host B can connect to the array without authentication. (If Host B uses Microsoft iSCSI Initiator,

Host B can connect to the array only when Host B is not conﬁgured for authentication by iSCSI targets

with CHAP.)

Host C's user information is not registered on iSCSI target 1. Therefore, when Host C tries to connect to

the array, authentication fails and the connection request is denied regardless of Host C's setting.

Host D is attached to iSCSI target 2, which does not perform authentication of hosts. Therefore, Host D

can connect to the array without authentication. In this case, it does not matter whether Host D's user

information is registered on iSCSI target 2. (If Host D uses Microsoft iSCSI Initiator, Host D can connect to

the array only when Host D is not conﬁgured for authentication by iSCSI targets with CHAP.)
