iSCSI RADIUS configuration

You can configure your storage systems to use RADIUS for centrally managing iSCSI initiator authentication.

RADIUS uses CHAP to authenticate iSCSI initiators, but it enables you to manage the authentication process from a central RADIUS server, rather than manage it manually on each storage system. In larger SAN environments, this can greatly simplify iSCSI initiator management, CHAP password management, and provide added security.

RADIUS also reduces the load on your storage system because most of the authentication processing is handled by the RADIUS server.
