At OCP Summit 2026, we saw Meta’s new MetaRoCE network adapter. This is Meta’s answer to providing an open RDMA transport layer that has features like packet spraying, congestion control, and more. This was a presentation we saw at OCP Summit, but Meta had a NIC on display.
Meta MetaRoCE Network Adapter at OCP 2026
Here is the display from the Meta booth at OCP Summit 2026, where you can see an OCP NIC 3.0 card.
During its OCP 2026 presentation, Meta shared some of the big features of MetaRoCE:
- Per-path reliability and congestion control
- Receiver rate hints (RCN) for fast incast convergence
- Tolerates packet loss and reordering
- Single QP carries multiple streams over multiple network paths
- Runs on commodity Ethernet: ECN + ECMP, no switch (Source: Meta)
Before OCP Summit, Meta demonstrated this with the AMD Pensando NIC series. The programmability allowed it to implement the protocol without having dedicated hardware. That allows Meta to potentially source from multiple vendors.
Meta is trying to build a network protocol that can scale to million-GPU training, but also that can run on different network topologies and hardware.
As a quick aside, the NIC shown was an OCP NIC 3.0 with SFF pull tab design, which is our favorite form factor that we wish all server vendors used.
Final Words
Given Meta’s heritage of starting OCP Summit, they usually have super-cool hardware in the booth. Last year, we got the AMD Helios MI450 Rack at OCP Summit with a Different Version from Meta as an example. This year, the company brought some larger nodes, but also small items like this adapter. It is always neat to see what Meta is working on.
