    @Jerry Chen

    Looks like your working directory is the one you unpacked the downloaded ixgbe driver to.

    But you haven't loaded the module you've built (assuming you've built it).

    The one that is loaded is the one that is included with your running kernel.

    Well I guess I will (try to) use a newer kernel when I have time.

    You might also use your build module by doing:

    cd [your_module_build_dir]
    rmmod ixgbe
    insmod ./ixgbe

    If you use the path of your built module you can load it instead of the one accompanying the kernel.

    Finally did it: Just ordered the 1540D-Board (X10SDV-TLN4F) and 2 x 32 GB ECC (Samsung). Hope this will fit all in my old case.

    Plan to virtualize a NAS (IBM 1015), a firewall and several other VMs for testing.

    ASRock have just put up their Xeon-D motherboards, finally!

    ASRock Rack > D1540D4I-2L2T
    ASRock Rack > D1540D4U-2T8R
    ASRock Rack > D1540D4U-2O8R
    ASRock Rack > D1540D4U-2L+
    ASRock Rack > D1540D4I
    ASRock Rack > D1520D4I

    Sadly no SFP units visible on the mITX boards as expected. D1540D4I-2L2T looking like the closest competition to the X10SDV-8C-TLN4F.

    Edit: M2 slots hanging off a Marvell 9172? Bleuch. Bleuch with knobs on. So much for using a nice M2 SSD for disc caching. Don't understand ASRock's continued fascination with those terrible marvell controllers... 9172 was bottom-of-the-barrel SATA controller three years ago...

    I could be wrong but I was pretty sure they were listed on their site previously. The issue is finding them somewhere to actually purchase. I was really hoping for my VM hosts for a mini-itx SFP+ model as 10GBaseT is absolutely useless to me. I could still use a single D1540D4U-2O8R though for another purpose once they ever go on sale and are available.

    They'd listed some of the boards in their 2015 catalogue before but this is the first time they've had product pages with actual pictures instead of schematics.

    Retail availability will of course be approximately 23 minutes before the heat death of the universe :)

    @EluRex:
    I wish I can give you more likes.
    You are the first one on the INTERNET to actually and properly test SR-IOV on Xeon-D
    Please keep this stream of info coming.

    @everyone:
    Some weird things on ASRock D1540D4I-2L2T specifications:

    and
    Edit: You can also spot M.2 in the motherboard picture, but nothing mentioned about it in the specifications.

    Edit: the schematics of this motherboard is really needed.

    Going from their 2015 PDF, the M2 on the D1540D4I hangs off one of the D15x0's SATA ports, there's no additional storage controllers listed. The mini-SAS port is apparently just four of those aggregated into one. Hopefully the manuals will go up in a few days and we'll get a better explanation.

    I don't understand the fascination with 10gbaseT. It's a shit technology and fiber is so much cheaper than it used to be.

    10 Gbe-T with SR-IOV is great for virtualization platform and remove the bottle of openvswitch/bridge/bond. None of the 10Gb SPF+ can be use by any VM and trying to bridge them will create huge performance hit (reduce about 40% of bandwidth). In addition, 10 Gbe-T also great use as NAS since 4K video are becoming command, if trying to stream 4k video to multiple end client via 1 gbe interface, the bandwidth gets saturated quickly.

    10 Gbe-T is much easier to configure and cheaper in comparison to Infiniband solution which should be solely used to interconnect the servers together. 10Gbe-T will be a great interface serving the end clients which only has 1 Gbe-T connection.

    But we can do this all with 10gb fiber ethernet. I concede your point about existing installations, although I would argue it's time to buckle down and run fiber anyway, which will last well into 100gbe. The amount of power needed for cat 6 just doesn't feel worth it (although I am reading that it's gotten better with new technology)

    For the sake of argument...

    1) Can you vendor lock-in a CAT6/CAT6e?
    2) Can you vendor lock-in a SFP+ module?

    If you answer "No" and "Yes", congratulation, I just passed the sarcasm test!

    I am a die-hard on infiniband and in my work environment, I sees the need to use of
    1. infiniband (SAN usage Server to Server),
    2. 10GBe-T (NAS usage Server to end client),
    3. 10GBe SPF+ (Switch to Switch), <--- its already vendor lock in
    4. 1GBe SPF+ (Switch to POE Switch) <--- its already vendor lock in
    is 10 GBe-T solution expensive? Hell yeah! Before it cost an arm and a leg and now it still cost an arm.

    Hi again,

    So is there a full procedure for the not-so-expert on linux for getting the SR-IOV working on both network controllers?

    Also how can one confirm that this cpu has x2apic support?

    Thanks a lot!

    "Releases" implies that these boards are actually available somewhere in the retail channel ;) I've certainly seen hide nor hair of them and the SuperMicro xeon-D boards are still like rocking horse poo in europe. The 15x1's might ostensibly be released in november but I expect it'll be mid-2016 at the earliest before you start seeing boards shipping.
