This 1.8.3 beta driver have 2 issues.
1. vSphere Host Profile creation problem.
If you create host profile on vCenter than you'll be failed every time.
2. Fixed 32 QD problem.
I was test massive svMotion last 2 hours.
But svMotion was failed or ESXi host failed to PODS...:(
This beta driver need a precision debugging...:(
I'm waiting new driver stack that support stable and able to tune iSER target on infiniband.
Because when you reboot your ESXi host vSphere SRP initiator can't log out from my ZFS COMSTAR SRP target.
That cause a initial connection stale to ZFS SRP target whenever ESXi host reboot. This is a known issue.
I'll wait for it until end of this year.
Then I'll test new driver then upgrade my infrastructure to RDMA IB or RoCE ETH.
