I'm install vSphere OFED 1.8.3 Beta driver yesterday.
iSER shows a good performance and reliability.
Single port test was show a good performance at 3.6GB/s throughput, but dual port wasn't.
Only 4.2GB/s. Because a PCIe 2.0 x8 slot's bottleneck...:)
But here is some qustions.
Q1. How can I change QD per LUN on iSER?
Q2. Whenever create Host Profile was failed on every ESXi 6 host with vSphere OFED 1.8.3.
Q3. What's your iSER target?
I'm using OmniOS now
When I prepared try CentOS 7 LIO iSER Target for VAAI support.
