    I have recently aquired a pair of hp branded broadcom 10Gbe nics SFP+
    HP Ethernet 10Gb 2-port 530SFP+

    I would like to do a switchless direct line between my windows 8.1 workstation and my linux NAS but haven't the foggiest on how to do it.
    I have the cards and I have a pair of transceivers but no cables.

    Where do I start. :)

    Static IP addresses. Same subnet.

    I don't know why I thought that would be harder than normal...

    Cables... I am clueless...
    What type do I need and what is a good price range.

    Depends on your transceivers

    I am assuming the NAS and your desktop also have a 1 GB nic each on your reg network? unless you only want to use IP addresses to connect to NAS, I suggest you come up with a DIFFERENT name for the NAS 10 gig interface and put it in your DNS or host file.

    Right... I have noticed there are cables that include them... but are you referring to something else as well?

    Cables with them included (well they are not really the same but yes let's pretend they are ) are called DAC cables
    Not fibre optic, but copper

    Come in lengths

    1m
    3m
    5m

    So depends if you need longer than 5m in between the two machines or not

    Oh DAC = Direct attach copper....
    Another name for it is twinax
    .

    Need the information on the transceivers. That part number does not seem to be right. If you want to use your transceivers, you can just get an appropriate fibre patch cable (monoprice sells them new for 10$-20$) this would the the simplest option. Just make sure to get the right fibre patch. I am 90% sure that your transceiver will be LC connectors. so you want LC to LC. then you need to check if your transceivers are single mode or multi mode etc. If they are like this 455883-B21, the typical short range 850nm (inside the DC type) SFP+ transceiver, then you want something like this.

    10Gb Fiber Optic Cable, LC/LC, Multi Mode, Duplex - 1 Meter (50/125 Type) - Aqua - Monoprice.com

    If you don't want to use the transceivers you can buy a combo cable called a TWINAX (or DAC) They act like 2 transceivers and a cable all in one. You just slide them into the empty SFP+ slot on each card and you are done. Sometimes you get into artificial and real compatibility issues, so order the supported HP cable if possible.

    Both options perform equally.

    That cable I linked should be all you need.
