Abstract
Techniques are described that can be used to support integrity validation of protocol data units. An iSCSI compatible logic may establish a memory region to store a header portion of the protocol data unit. In some implementations, the iSCSI compatible logic may read the header and determine a size of a second memory region to store a payload portion of the protocol data unit. In some implementations, the iSCSI compatible logic may set the second memory region as a maximum possible size of the payload portion. TCP compatible logic may include the capability to validate an integrity of the header or data portions of the protocol data unit. TCP compatible logic may request data mover logic to determine an integrity validation value for a header and/or data portion of the protocol data unit in the process of copying the protocol data unit to among the memory region or the second memory region. TCP compatible logic may compare the determined integrity validation value with an integrity validation value included with the protocol data unit.
