GPUDirect RDMA
Data moves between GPUs and NICs without detouring through the CPU — the exchange speed your all-reduce actually needs.
Products · Networking
The layer everything connects to
Non-blocking InfiniBand for GPU clusters and carrier-neutral connectivity for everything else — engineered so the network is never the bottleneck.
Fabric
Up to 800 Gb/s to every GPU
Training clusters ship with dedicated 400 or 800 Gb/s InfiniBand per GPU — 3.2 Tbps per 8-GPU node — on a non-blocking Quantum fabric.
GPUDirect RDMA
Non-blocking fabric
Tenant isolation
Topology-aware scheduling
Multi-tenant isolation
Each GPU cluster gets a unique partition key on the shared fabric — tenant-level isolation inside one physical network.
Topology-aware scheduling
Slurm and Kubernetes receive live topology files, placing jobs on the closest nodes — measured NCCL gains of up to 20%.
Non-blocking at scale
Quantum-2 / Quantum-X800 fabrics scale clusters to thousands of GPUs with linear all-reduce performance.
Carrier-neutral to the world
Our meet-me room hosts 10+ carriers and cloud on-ramps: blended IP transit, private lines, cross-connects and DDoS-protected upstream — provisioned in days, not weeks.
- Blended IP transit & private lines
- Cross-connects within 3 business days
- Direct on-ramps to major public clouds
