The impact is that for users of motherboards like the Supermicro X10SDV-4C-TLN2F we reviewed, this makes installation significantly easier. Of course, 15.10 has relatively short release support, but this is a major upgrade. It means that Intel Xeon CPU users can use 10Gbase-T networking out of the box.
Ubuntu has been one of our most utilized OSes simply because of the lack of SR-IOV support with the current Intel Xeon D series. We saw a few more Intel Xeon D motherboards on our trip to Taiwan this week. Rest assured, more are coming.
