Advanced TCP Configuration iSCSI Parameters
•
Selective ACKnowledgement
- (SACK) allows acknowledgement
of non-contiguous sequence numbers to reduce the amount of
retransmitted data when packets are lost. Enable this for better
performance in congested networks (assuming the remote
device also supports SACK).
•
Large PDU
- When enabled, the SAN Router delivers data to
iSCSI end nodes using maximum length iSCSI data PDUs,
independent of how data is received from the FC device. The
maximum length (MaxRecvDataSegmentLength) is
negotiated at login.
•
Digest
- This adds a digest (extended checksum) to each
payload for end-to-end integrity checking.
