Exadata X8-2/X8M-2 don't support 1GbE client network


 One our Exadata customer started using Exadata from X3-2 model, seven years ago.
Now it still using 1GbE (copper Gigabit Ethernet ) in its enterprise network.

But today 1GbE for Exadata X8-2/X8M-2 is the problem: as became known Exadata X8-2/X8M-2 don't support 1GbE. 


Here answer from the SR: 
" We have checked on this whether any of the ports on X8s are supported to run at 1GbE, and the answer was 'no', we don't test at 1GbE, thus we don't support 1GbE. This is for both "copper"/RJ-45 10GBase-T, and the SFP28 with 10GbE transceivers. While the underlying hardware may/does support 1GbE, as an engineered system, X8s/X8Ms do not support the same. "


But the good news: "Don't support" doesn't mean "don't work" !!!

The documentation say the X8-2 server support the 1GbE copper:

And the Exadata's rear pannel view shows 1GbE:

So we asked our engineer to test 1GbE ports on X8-2 and he confirmed ports NET1/NET2 working at 1GbE .  He manually set 1GbE on ports and copied some files through these ports:
