iSCSI

iSCSI is a type of network storage technology that offers high expandability and low implementation costs. Through existing network infrastructure and iSCSI you can use your NAS to expand existing storage space or have it act as a backup destination. iSCSI consists of two ends, a target and an initiator. The initiator is used to search for iSCSI hosts and to set up targets.

  • IQN: IQN (iSCSI Qualified Name) is the unique name for each iSCSI target. This name should not be the same as any of the other target IQNs on other hosts.
  • CHAP Authentication: CHAP authentication can be used to verify a user's identity. If you choose to use CHAP authentication, a CHAP password must first be entered from the initiator for verification before it can connect to the target.

    Note: When enabling mutual CHAP authentication, the authentication password used by the server and client cannot be the same.
  • Mutual CHAP Authentication: Mutual CHAP authentication requires both the target and the initiator to have usernames and passwords. When establishing a connection, the target and the initiator will have to authenticate each other using their respective credentials.
  • LUN Pool: Here you can check on the status of all iSCSI LUNs and assign corresponding iSCSI targets.
  • iSNS Server: iSNS (Internet Storage Name Service) iSCSI management. Here, you can register iSCSI targets with the iSNS Server, for convenient centralized management.
