It’s one single card with 4 interfaces. It came onboard on the IBM System x3550 M4 servers that I’m using and they are Intel based, don’t remember exactly which chipset. Anyway this is interesting, I really avoid mixing different controllers on bonding to keep things stable, but you’ve a point. > Just my two cents, > >> >> Thanks, >> V. >> >> _______________________________________________ >> Users mailing list >> Users@ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users > > > > -- > Didi _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
