>10 available for both, sale ends in just over 1 day.

100 Gbe: Chelsio Communications 110-1220-60 Dual Port 40/50/100gbe Network Adapter | eBay - 110-1220-60 - T62100 LP-CR - 74.99$ (sometimes seller offers 10% discounts, therefore probably would accept an offer for a 67.49$ because of that or maybe even lower)
25 Gbe: Chelsio Communications T6225-CR Dual Port 110-1209-60 1/10/25GbE Network Adapter | eBay - 110-1209-60 - T6225-CR - 29.99$ (sometimes seller offers 10% discounts, therefore probably would accept an offer for a 26.99$)

Both comes with low profile bracket though

I myself bought 2 of each for tests/playing around (I haven't tried offering lower than current prices though, but seller might accept few extra $ lower), but I would get them probably in few weeks at best.

UPD 04 Nov 2024: updated title and the post to current price, as 10% discount expired.

Airflow for such cards comes without saying. You can use them in PC cases, but you need to ensure that airflow is there. I'm not sure about Chelsio ones, but for Mellanoxes, Intels and Broadcoms either a small blower fan on low RPMs or a bigger fan is enough to keep even 100GbE cards cool.

About drivers, AFAIR, they were recently (in 5.x kernel series) contributing a lot upstream and it should have if not feature parity with their own one, but be very close to that. At least I remember seeing TLS offload work done upstream.

Thanks for sharing, I think these support iWARP for RDMA so could be useful for a Microsoft Storage deployment.

I think the driver support is more mature on the Mellanox range.

I wouldn't call that a low profile bracket as it seems to come out of an Applicance of sort but should work :D

I was going to mention the same thing about the bracket. According to the pictures, that's not a low profile bracket. More like a no-profile bracket. But @Civiloid , you bought one, can you confirm it comes with a low profile bracket?

Atermarket brackets appear to be available on eBay last time I checked. When I bought my cards a year ago I had to order brackets from Chelsio for considerably higher cost.

It comes with the "no profile" bracked, like they have on the photo.

I wonder if there's a simple 'L' bracket one can get and attach to the no-profile to get the lip needed to secure it like a low profile.

Mmmm why go with this over a cx4 card?
Click to expand...
It is about 2-3x cheaper than CX4 2x100G.

For me, what is more interesting is to have a collection of decent (small packet performance) cards as I'm, as a hobby, playing around DPDK (and I already have CX5, 6, 7, BF1 and multiple BF2s). And Chelsio should be somewhat around CX4 in terms of performance.

Really? Not in my experience. Guess I just got some good deals.

Right now - 128$ for cx416a-ccat (+shipping, for me about 10$ extra). You can get cx416a-bcat and reflash it, but that is 79.95$ in US. And for me (delivery to Switzerland), an extra 36$ for delivery, which makes almost double the price of Chelsea.

Chelsio has some sort of HW encryption and apparently rather good one, while in terms of Mellanoxes, you only have that in BlueFields and CX6 or newer.

Some people here wanted it specifically for iWARP support (honestly, I'm not sure how useful that is, but NVMEoF and SMB Direct can use that)

All I can say is that I personally have never paid a price even remotely close to those amounts.

From what I understand iWARP isn't as performant as RoCE but that's documentation and proof provided from Mellanox. I'm a noob with these things so I ask and speak with no expertise.

The biggest advantage of iWARP is that it just works. But RoCE is more performant and has significantly lower latency.
I think I have paid on average around 60-70 USD for my 100G Mellanox Nics. There are deals here and there all time, most of the times there are only 1-5 units though. Last year I managed to get 5x ConnectX-5 100G for just 65 USD ea :)

Ever considered using Ceph, or thought about considering it? Whatever network you have now, you'll wish it was faster once you start using Ceph. Unless you've maxed out all the I/O to your drives with your current network.
