I'm looking at the Dell R220 which lists the Emulex OneConnect OCe14102-UX-D 2-port PCIe 10GbE CNA or Intel X520 DP 10Gb DA/SFP+ Server Adapter. The OCE driver doesn't list the 14102 as a listed device that is supported, but ix does list the X520-DA2. Is it safe to assume that the DA and DA-2 are the same or similar chipsets and will work? I'd likely be running 5.8-CURRENT on this box. -- James A.
