Term Explanation

IQN: IQN (iSCSI Qualified Name) is a set of unique name for an iSCSI Target. It should not conflict with iSCSI Target IQNs on other servers. IQN must be less than 128 characters and can include letters(case insensitive), numbers, colons, dashes, and dots. The suggested naming format is iqn.[date].[domain]:[device identifier], for example: iqn.2000-04.com.synology:storage.diskarray.1.

CHAP authentication: If you select CHAP, the server will be able to verify the client's identity. In Mutual CHAP, both the client and the server will authenticate each other. Username can be composed of 1 ~ 12 letters and numbers, and password can be composed of 12 ~ 16 letters and numbers.
