QTS starts creating a dedicated iSCSI target on the remote NAS for the VJBOD disk.
20.
Optional: Enable CHAP authentication.
An initiator must authenticate with the target using the specified username and password. This provides
security, as iSCSI initiators do not require a NAS username or password.
• Username
• Length: 1 to 128 characters
• Valid Characters: 0 to 9, a to z, A to Z
• Password
• Length: 12 to 16 characters
• Valid characters: 0 to 9, a to z, A to Z
21.
Optional: Enable CRC checksums.
Initiators and targets communicate over TCP connections using iSCSI protocol data units (PDU). The
sending device can send a checksum with each PDU. The receiving device uses this checksum to
verify the integrity of the PDU, which is useful in unreliable network environments. There are two
checksum types, which can be enabled separately.
