Optional: Select the remote interface that will be used by VJBOD.
10.
Optional: Enable iSER.
Enabling iSER increases data transfer speeds and reduces CPU and memory load.
a.
Ensure that selected local and remote network adapters are iSER-compatible and have
iSER
listed under
Supported Protocols
.
b.
Select
Use iSER when available

16.
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
17.
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.
Checksum Type
Description
Data Digest
The checksum can be used to verify the data portion of the PDU.
Header Digest
The checksum can be used to verify the header portion of the
PDU.
