hi guys
I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too.
I'm trying poor man's setup to get the servers onto 10GbE network.
Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast mode. And it all seems to work, they ping each other, iperf okey.
The problem, big problem is that when traffic start to flow between all three servers simultaneously, with rsync for example, then!! one box gets shoot in the head, hard reset, gone. Every time same one box.
Sure there are some bits that run on that one box that are not on the other two.
Now, I know you would normally put it via a switch, but like I said: poor man's config, but you would not expect system to die like this neither, right?
many thanks, L.

What CPU do they have?
