[gpfsug-discuss] more than one mlx connectx-4 adapter in same host

[Knister, Aaron S. (GSFC-606.2)[COMPUTER SCIENCE CORP]]

We’ve done a fair amount of VPI work but admittedly not with connectx4. Is it possible the cards are trying to talk IB rather than Eth? I figured you’re Ethernet based because of the mention of Juniper.

Are you attempting to do RoCE or just plain TCP/IP?

Hello:

Does anyone have this type of config?

The host configuration looks sane but we seem to observe link-down on all mlx adapters no matter what we do.

Big picture is that we are attempting to do mc(multichassis)-lags to a core switch.  I'm somewhat fearful as to how this is implemented in the juniper switch we are about to test.
