Title:
METHOD AND SYSTEM FOR SUPPORTING READ OPERATIONS FOR ISCSI AND ISCSI CHIMNEY
Document Type and Number:
WIPO Patent Application WO2006002126
Kind Code:
A3
Abstract:
Certain embodiments of the invention may be found in a method and system for performing a SCSI read operation via a TCP offload engine. Aspects of the method may comprise receiving an iSCSI read command from an initiator (118). Data may be fetched from a buffer based on the received iSCSI read command. The fetched data may be zero copied from the buffer to the initiator (118) and a TCP sequence may be retransmitted to the initiator. The method may further comprise checking if the zero copied fetched data is a first frame in an iSCSI protocol data unit and if the buffer is posted. The retransmitted TCP sequence may be processed and the fetched data may be zero copied into an iSCSI buffer, if the buffer is posted.
