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.

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...
