Re: re: TCP Offload Engine It's the difference between a $10 NIC and a $500+ NIC. :-) The problem it solves is that processing TCP/IP packets takes a fair amount of compute power. At 10Gbe, where ISCSI becomes attractive, just processing the TCP/IP I/O stream can saturate a high end CPU. By offloading that processing (producting and validating packet checksums, etc.) to the card, that load is kept off the CPU and local crossbar connections. So you either have a TOE engine, or you lose two cores (one at each end) of every host and storage system running ISCSI. Some interesting papers are here: chelsio.com
