Review: Great cards & drivers - Great cards, and more importantly, even better drivers. Bought some of these to work around constant issues with Intel cards experiencing failures under vmware; problems disappeared, and side bonus is they do 25gig with SFP28's if you have the relevant switches on the other side. Intel and vmware both blame each other, so regardless of who's correct, you're stuck in the middle with a useless 10gig nic.

## Features

- Tag matching and rendezvous offloads
- Adaptive routing on reliable transport
- Burst buffer offloads for background checkpointing
- NVMe over fabric (NVMf) offloads
- Back-end switch elimination by host chaining
