Care to be more specific about the performance you achieved? You might want to contrast your numbers to veritest verified numbers of 800+ MBps and 600+KOPS achieved by Chelsio HBA with stateful offload using either 1500B or 9KB MTU (for full detail see Veritest report at http://www.chelsio.com/technology/Chelsio10GbE_iSCSI_report.pdf) 'Asgeir
FYI, http://biz.yahoo.com/prnews/050329/cgtu006.html?.v=4 The actual whitepaper with performance results is on our site. In short, it shows that it's fine to run sw iSCSI over 10GbE NIC with Linux-supported stateless offloads (receive side could use more of these though :-)), on a generic Opteron box. Leonid
I changed the subject, btw. In your paper. Its 28 M$ Initiator against one iSCSI Target on top of Chelsio HBA. Now prove me that Chelsio HBA as an Initiator can do somewhat close to 100K IOPS with regular Linux SCSI-MidLayer... Regards. Dmitry
