The QUASAR Spectrum-X 800G Ethernet AI Fabric Kit is a turnkey Ethernet AI fabric kit \u2014 a high-bandwidth Spectrum-X switch plus BlueField-3 DPUs, providing 32\u00d7 800G + BlueField-3 DPUs at 25.6 Tb\/s over Spectrum-X Ethernet (RoCE) + BlueField-3 DPU, with Low-latency RoCE. It is the interconnect that turns GPU servers into a cluster, carrying the collective (all-reduce) traffic that dominates multi-node AI training \u2014 on-premises, in INR, on a GST invoice.<\/p>\n
Engineered as the fabric layer of an RDP AI cluster, it is delivered configured, cabled and validated alongside the compute and storage it connects, with DPUs that offload networking, storage and security from the host CPUs.<\/p>\n
The Spectrum-X switch runs RoCE over Ethernet with adaptive routing and congestion control, while BlueField-3 DPUs in each host offload networking, storage and security \u2014 keeping the fabric lossless and the host CPUs free \u2014 so all-reduce traffic, which dominates multi-node training, completes fast. RDP sizes the topology (oversubscription, spine count, DPU count) to your cluster. Honest note: real scaling efficiency depends on topology, collective library and model \u2014 we validate it on your cluster, not just a peak number.<\/em><\/p>\n We don’t publish inflated peak numbers. The honest picture: 25.6 Tb\/s at Low-latency RoCE is sized to carry cluster collectives without becoming the bottleneck. Want certainty? Request a free scaling test of your training job across nodes on this fabric before you buy<\/strong>; we’ll send back real all-reduce bandwidth and scaling efficiency.<\/p>\n An owned fabric is a one-time asset that removes the per-node networking premium of cloud GPU clusters and keeps the data path in-house. RDP pricing is fixed in INR with a GST input-credit-eligible invoice \u2014 ask for a fabric design and TCO<\/strong> for your cluster.<\/p>\n Integrates with the AI stack: NCCL over RoCE, NVIDIA Spectrum-X and DOCA for the DPUs, with fabric monitoring and telemetry. Validated with RDP GPU servers, rack-scale systems and storage.<\/p>\n A Switch + DPU kit with redundant PSUs and front-to-back airflow \u2014 specify rack power, cooling and cable plant (DAC\/AOC\/transceivers). (Exact power draw, BTU and cabling confirmed on the build sheet.)<\/em> Full out-of-band management.<\/p>\n 14 years of Make-in-India infrastructure and 300,000+ devices shipped<\/strong>.
