The problem is that I am using one target/LUN per port as I am sharing PCIe SSDs backed LUNS with high IOPS. Basically, this was the recommendation from Mellanox such that I have one session per port. In my testing when it was working, I was getting about 800KIOPS for 8 sessions. I do need to be able to use different ports.
Thank you.
