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
