Running hot rather comes with the territory. 12.5 Gbit/s symmetrical of throughput runs warm

Curse you all for mentioning NICs. A 2 SFP+ port card has fallen into my shopping cart.

Curse you all for mentioning NICs. A 2 SFP+ port card has fallen into my shopping cart.

I was very tempted to get a 2 port but I figured I might need that money for, you know, food, bog roll, etc. 

I ended up getting an Intel X520-DA1 which hopefully will work with the 10Gtek DAC cable.  They claim it works with their version of that card, but then they charge twice as much for theirs as I got that one for new off eBay.  (I could have gotten a 2 port card for the price of their 1 port)

Reading the Linux kernel module documentation is kinda scary, as it implies by default it blocks all SFP+ modules/DACs that have not been tested which seems kinda silly IMO.  I know adding module options isn't hard, but I'm always expecting them not to work.

For personal reasons this project has been indefinitely suspended and there'll be no updates for the foreseeable future.

Thank you, everyone, for your comments, feedback and interest.

Wow, the DAC arrived and the pictures make it look super thick, I was worried about the bend radius - but its tiny, way thinner than ethernet.

I mean the bend radius is still bigger due to the SFP+ connectors but getting round the back of the server without kinking is going be no issue at all.

Guys what kind of card are we talking about, in hardware platform terms? Are we talking about a desktop class PC? Or server or what?

[aesmith]

Intel call it a "server adapter" but of course it could be put into a desktop PC as long as you had a suitable slot.

Anything with a PCIe slot, if I am remembering correctly.

Thank you for posting those images. They are exactly as I expected. However we do seem to have hijacked CarlT's thread.

Well he did say:

Could always split the thread off, to keep the last sort of it more visible.

[Alex Atkin UK]

I don't feel we went that far off-topic, it is a forum not a blog after all so discussing 10Gbit seemed relevant.   But its not my forum nor thread.

[niemand]

False alarm, all is well, please carry on with the discussion.

Nice and simple at the moment - here's what we have attached.
