CHAP Accounts

Challenge-Handshake Authentication Protocol (CHAP) is an authentication method that servers use to verify the identity of remote clients. CHAP verifies the identity of the client by using a handshake when establishing the initial link and at any time afterwards. The handshake is based on the exchange of a random number known to both the client and server.

CHAP accounts are not required to establish a functional data connection between an array and a Windows server or ESXi host.

NOTE: CHAP works only with iSCSI; it is not supported on Fibre Channel.
