Performance & Scalability

AI Fabric Architecture

The NVIDIA Quantum-2's 51.2 Tb/s bidirectional capacity and the Dell Z9864F-ON's 102.4 Tbps full-duplex capacity describe the same architectural pinnacle: a 51.2 Tb/s non-blocking switching fabric.

Massive AI Scale

Two-tier Fat Tree with Quantum-X800 supports 10,368 NICs at 800Gb/s. Z9864F-ON supports 8K GPU nodes in a single fabric.

In-Network Computing

SHARPv4 offloads math operations to switch silicon with FP8 precision — up to 9X performance boost. SHARPv3 provides 32X acceleration on Quantum-2.

Lossless Protocols

RoCEv2, PFC, DCBX, and ETS ensure deterministic performance. Adaptive routing and cognitive routing dynamically avoid congestion hotspots.

NVIDIA Quantum-X800 (Q3450-LD)

Co-Packaged Optics reduces insertion loss from 22 dB to 4 dB (63X signal integrity). 85% liquid / 15% air cooled. Hardware Root of Trust (IRoT), Secure Boot, TPM 2.0. NVOS with dedicated in-band management port.

Looking Ahead

Frequently Asked Questions

Yes. As the industry moves beyond standard generative AI toward Agentic AI—where autonomous agents execute complex, multi-step workflows—the demand for continuous, high-speed data movement increases. Our high-bandwidth, low-latency fabrics provide the lossless, single-hop communication required to keep Agentic AI systems synchronized and running without bottlenecking the CPU.

Yes. Trillion-parameter models require strictly lossless, high-bandwidth East-West fabrics to synchronize gradients across thousands of GPUs. Our 400G and 800G platforms deliver the non-blocking throughput, deep buffering, and in-network computing capabilities (such as NVIDIA SHARP) required to minimize tail latency and keep GPU clusters fully utilized.

Choose platforms that support multi-rate connectivity (100/200/400/800G) with breakout capability for phased migration. Open networking with Enterprise SONiC or ONIE ensures you are never locked into a single vendor's roadmap, while SmartFabric Manager provides lifecycle automation as your fabric evolves.
