PFC on esxi 6.5

Does anyone know how to configure PFC on an esxi 6.5 host for connectx-4 cards?

i followed the following guide to configure linux, however mlnx_qos does not seem to exist for esxi, nor does the python script in the guide:

Hi Grant,

Please see the following user manual Mellanox ConnectX-4/ConnectX-5 NATIVE ESXi Driver for VMware vSphere 6.5.

Please see section 3.1.4 Priority Flow Control (PFC) :…



Karen, Thank you for the reply.

Can you tell me what is Mellanox’s recommended configuration if there is just 1 traffic flow? My connectx-4 cards are direct connected between two servers and used only to connect the iser initator to the iser target. There is no other traffic on these nics. I have seen references to creating a vlan and assigning it to one of the priority queues yet none of this applies to my scenario. Should i just run global pause?
