NETWORKING

The network edge to the GPU, end to end.

Move large datasets in and out of the cluster fast, encrypted between sites and resilient at every layer.

THE EDGE

Always-on Connectivity

Carbon IBM devops control

Diverse carriers

Independent physical routes for internet and inter-site traffic.

Bring-your-own addressing

Private space preserved, with tenant-scoped routing and NAT.

Edge protection

L3/L4 DDoS mitigation at the internet edge, extensible to L7.

Inter-site Connectivity

Secure, reliable connections between sites.

Secure by Design

MACsec on private links; IPsec to enterprise environments over public networks.

Built for Bursts

Committed capacity with plenty of headroom for bursty traffic.

Always Redundant

Redundant data paths between every pair of connected sites.

The compute fabric, four planes

Dedicated planes for contention-free performance.

GPU fabric

Quantum-X800 InfiniBand at 800 Gb/s per port, non-blocking across the cluster.

Storage fabric

Dedicated throughput for parallel loads and checkpoints, separated from the compute path.

Tenant and service networks

Customer workloads isolated, connected to platform services.

Out-of-band management

A dedicated fabric to keep operational activity from competing with production traffic.

Latest NVIDIA hardware

Rapid data movement for scale-up and scale-out.

Redundant, edge to fabric

Failover paths at every layer.

Redundant fabric

Multiple spine-and-leaf paths absorb the loss of a link or switch.

Dual-homed nodes

Compute, storage, and control connect through separate switches.

Diverse carriers

Independent providers and physical routes to your infrastructure.

Validation and operations

Proven for reliable, scalable operations before handover.

Pre-production Validation

Routing, control-plane behavior, and traffic flows tested before handover.

Expansion without Redesign

One design scales cleanly across racks, pods, and sites.

Full-lifecycle Operations

Monitored, maintained, and expanded as part of the running fleet.
