NVIDIA is making advancements in their Linux InfiniBand driver to support 800Gb/s (XDR) speeds. The company has posted a set of six patches for the upstream Linux kernel, aiming for inclusion in Linux 6.7. These patches will enable the 800Gb/s support in the InfiniBand core networking code and the Mellanox MLX5 driver. The NVIDIA Mellanox Skyway GA100 InfiniBand to Ethernet Gateway is believed to be the first product capable of achieving the XDR speeds. This development showcases NVIDIA’s commitment to delivering high-speed networking solutions for servers.
The details of the preparations for the 800Gb/s (XDR) speed implementation in the Linux kernel’s InfiniBand code can be found in the patch series provided by NVIDIA.
