Hopefully for $23 you'll get it shipped properly (anti-static bags etc). People should give feedback on that even when the price was low as $12. I would prefer packed inside a newspaper than inside a bubble wrap.The latest sale where it states 50 items per lot is actually a mistake. I just got notified by the seller asking if I wanted a refund or the individual cards. That being said, if these are truly the ConnectX-3 cards and are fully functional, then even at $23 a card with the shipping is still a great price.
No, my package is on its way. Probably it takes a week to get into the EU. On eBay there's Dual port 10/40Gbps Mellanox NICs for ~$60.@hakabe, have you tested your cards yet? with the normal price of ~$80-$100 a card on ebay for something comparable, I am wondering if this is just an awesome deal or if someone made a different mistake or sold a bunch of untested cards.
I received my cards yesterday and did some quick testing this morning on one of the cards.I am wondering if this is just an awesome deal or if someone made a different mistake or sold a bunch of untested cards.

Verified with the Finisar FTLX8571D3BCL.Do Cisco SFP-10G-SR or Finistar FTLX8571D3BCL work with these cards?
One foot to the heater radiator and you're all set...just have to ground yourself before handling.
Only Connectx-3 Pro cards and Connectx-4 and above cards support RDMA aka ROCE for these Eth cards.Great news @britinpdx, I purchased 2 of the cards under the first deal and then regretted that I didn't get more even if I couldn't use them all, I could have at least have some spares. When I realized that the same seller was selling more cards, I got more of those cards through a offer so I got them a bit cheaper than $23 and now I am happy that I did.
With these cards supporting RDMA, they should do great for using them for SDS(Software Defined Storage) testing which requires really low latency network configuration.
I sure hope you are wrong in that statement.Only Connectx-3 Pro cards and Connectx-4 and above cards support RDMA aka ROCE for these Eth cards.
I'm right. The Brochure caused me to think the same thing thus why I own some pro cards and non pro cards. Here's the details you're looking for : http://www.mellanox.com/page/products_dyn?product_family=79 .. Scroll down to hardware support at the bottom.I sure hope you are wrong in that statement.
Reading documentation it doesn't state anything regarding only Pro versions having the RDMA capability:
http://www.mellanox.com/related-docs/prod_adapter_cards/ConnectX3_EN_Card.pdf
Fudge@0xbit, I guess I am still hopeful and here is why:
- User ophirmaor in the community thread is explicitly stating that RDMA is supported on both types (VPI and EN) and that Pro supports RoCE v2 but non-Pro supports v1
- Reading the WinOF (not WinOF-2) user manual which can be found here: LINK
is stating that RoCE is supported on ConnectX-3 and ConnectX-3 Pro with firmware version 2.30.3000 or higher (page 44 under System Requirements)
Double FudgeRDMA over converged ethernet works with mellanox adapters since the cx-2 ethernet adapters (the "cheap as dirt" cards ).
For cx-2 you will need a certain firmware version that's only available through hp, cx-3 and newer adapters should support it with any firmware version.
For rdma on windows you need to enable "NDK Global Pause" in thre driver settings.
Awesome! Could I trouble u to print say 4 for me?So, seeing as how I will be 3d printing myself a dozen full height brackets for these cards, if anyone else needs some send me a PM.
