High-performance fabric
The fabric connecting every GPU on our platform — 400G NDR InfiniBand for Bare Metal training jobs and 800G RoCE v2 for VM and Container flexibility. Choose the transport that matches your workload.
RDMA over Converged Ethernet (RoCE v2)
The fabric connecting our AMD Instinct and NVIDIA GPU clusters
RoCE v2 is the default interconnect for our AMD Instinct MI350X, MI300X and MI325X instances, as well as for VM and Container form factors where customers need RDMA performance without a separate InfiniBand fabric. All GPU models on our platform — across Bare Metal, Virtual Machines and Containers — can be connected via RoCE, with Managed Slurm and Kubernetes scheduling jobs directly onto RoCE-connected GPU pools.
InfiniBand NDR / XDR
The lowest-latency fabric for the largest Bare Metal training jobs
InfiniBand NDR is the premium fabric option for Bare Metal deployments of AMD MI350X, MI300X and NVIDIA H200 — the GPUs used in our largest training jobs. Choose InfiniBand when your workload demands the absolute lowest AllReduce latency across hundreds of GPUs. InfiniBand is available on Bare Metal instances in our Glasgow, London and Texas data centres, with Managed Slurm providing native Slurm scheduler support for IB-aware job placement.
