[OmniOS-discuss] Intel C600 driver issue

[Dan McDonald]

I believe the "difficult" one, as you put it, is the SCU (ahh, you even call it out in your PCI scans).

Illumos has no driver for the C600 SCU, so you're out of luck. There was a prototype rumored to be floating around, but given most people ponied up for an LSI SAS HBA, which performed better, there was not a strong community push to get it up and running.

Sorry I don't have better news,
Dan
