Mellanox 354A Pro $40

Here is a listing of Pro cards. I have not seen these listed lately below $90 mark.

INFINIBAND FDR/ETHERNET 10GB/40GB 2-PORT 544+QSFP ADAPTER | eBay

Seems to be HPE branded:

• SKU: 764284-b21
• HPE InfiniBand FDR/Ethernet 10Gb/40Gb 2-port 544+QSFP Adapter (764284-B21) - Produkt Dokumentation

As such, there seems to be some effort involved in order to flash them:

The HP / Oracle MCX354A (non pro version) can be had for $20-25 all day long and plenty in supply. The ones I linked in my OP are the Pro version and usually list for $90.

Worth the difference in price though?

another pro for the pro version: it's supported for a longer time than the regular card

Worth the difference in price though?

It depends

if you wont to dig in the hyperconvergent architecture like microsoft storage space direct (even if also work with rocev1) and (if i recall correctly) nutanix ce, so yes.

These cards usually run around $35 or so now. Still, a decent price. I have yet to figure out cabling though. May post a question on the network threads.

netapp sas qsfp cables are cheap, and works just fine

Also supports acceleration for VXLAN, and perhaps a couple other protocols, I forget.

Picked up 5 of them. Thanks for the heads up!

If I don't want to spend the money, just need to post here and they are gone in a blink.
