Good Afternoon,
I have faced a PSOD problem with ESXi 6.5.
Each port of Mellanox Connect x4 passes 2 virtual functions to Windows 2016 VM with StarWind HA target. Synchronization channel works through the first port of the virtual function. iSER connection to StarWind HA IMG Datastore works through virtual functions of the second port. Targets are being connected to ESXi using VMware iSCSI over RDMA (iSER) Adapter. After I have connected StarWind HA IMG Datastore to the ESXi cluster, which consist of 2 nodes, I am creating a Test VM on this Datastore. I see PSOD on both nodes in different moments of time.
I have not found any Mellanox Connect x4 drivers for ESXi 6.5 on Mellanox website.

Have you faced such problems? Does anyone has any idea what to do with this?
Hey,
mellanox 6.5 drivers will be released on 31.12.2016, their support told me today 
Im using the out-of-the-box nmlx5-core drivers from the 6.5 ISO to get my Connect-X4 running. Works fine so far.
Using HP Hardware here with PCI-E 8x but not 16x. Not sure if this is a problem :smileygrin:
But my 2 test-hosts work fine so far with 100G and the Mellanox 100G SN2700 Switch
