Looks like Chelsio T6 100G NIC can anybody confirm?

For GBP 89.99 looks like good deal. Be warned Chelsio at least older NICs are locked to be useable only with Chelsio branded optics/cables.

That's almost identical to mine, although the one I had out and could check has the part number 110-1220-60 02 - but otherwise, I couldn't make out any noticeable differences. And for what it's worth, I've not had any trouble with third party transceivers with this model.

Mine 4pcs of Chelsio T6225-CR works with any transceiver... not to mention their fantastic support in case if issues, KUDOZ to these guys

BIGTINDAHOUSE23 5% discount code on that shop
Code didnt work for me, but
they auto-accepted 69.99 BO on 2

I already have 4 of those from a great deal years ago and they are pretty nice - hot for sure, but iwarp just works with the Chelsio drivers out of the box (even on TrueNas). So if you want 100G RDMA on TNC, these are the way to go (or the newer 7's I assume)

How to solve the problem of bracket?
I would get Mellanox bracket if the mounting holes will align.if not at least one should. Another issue might be QSFP hole in bracket whether will prevent you from inserting transceiver just perform bit of Autoreiji on it with file.

Those wont fit MLX brackets, they have some weird ones with a set back upper mounting hole. You can see it on one of the pics.
No idea if you can get replacement brackets for these, but if not a 3d printer surly will help.

Maybe the discount is bind to my account, sry

I bought two 6225-CR from the seller and have just received two of the above cards with P/N 110-1220-60 A0 instead. o_O Full x16 and QSFP slots.
Not what I expected, but I suppose I can't really complain about the upgrade…

Does someone knows of a comprehensive list of Chelsio part numbers to look up whether this is the 62100 LP-CR or SO-CR? And possibly look up replacement brackets?

Chelsio support confirmed that 110-1220-60 A0 is T62100 LP-CR. They can provide brackets for $25+shipping.

Even with this extra, the £90 cards are a terrific deal.

Are they? Did you test with non Chelsio transceivers?

I do not have 100G optics (remember: I expected 25 GbE cards!) to test right now, so tests will have to wait. Chelsio-coded transceivers from FS.com cost the same as transceivers for any other vendors anyway.
For now, let's say that these cards look like a terrific deal.

My understanding is that by plugging a QSFP+ 40gb DAC into these NICs, they will communicate with a 40gb Ethernet switch, is that correct? (in Linux, at least?)
