yes and no ...
For single session, yes.
For multiple sessions, no ... lots of different initiators with aggragate of 400K into single target.

about this 400K IOPS, both ini and target are using your HW solution?

Regarding the numbers, we get 400,000 IOPS with our hardware solution using multiple connections and multiple micro-engines. I have not tried multi-pathing but I can tell you that I had to count clocks to get that number and found that even a few extra clocks could mean a lot. So since multi-pathing takes a lot of extra clocks, then I think there is a benefit. However with a software solution the extra clocks for the multi- pathing may not be significant.
