The DRACO 512-Node InfiniBand XDR Fabric is RDP’s flagship turnkey InfiniBand fabric \u2014 a non-blocking spine-leaf interconnect that wires an entire GPU supercluster, providing 512 nodes \u00b7 2,048\u00d7 800G at 1.6 Pb\/s aggregate of aggregate bandwidth over InfiniBand XDR (Quantum-X800), with Sub-600 ns. It is the interconnect that turns a data hall of GPU servers into one supercluster, carrying the collective (all-reduce) traffic that dominates frontier AI training \u2014 on-premises, in INR, on a GST invoice.<\/p>\n
Engineered as the fabric layer of an RDP AI supercluster, it is delivered designed, cabled and validated alongside the compute and storage it connects, as a single non-blocking system with one warranty and one support contract.<\/p>\n
The fabric forms a non-blocking spine-leaf topology with RDMA over InfiniBand; the subnet manager programs routes, in-network compute (SHARP) offloads reductions, and adaptive routing avoids hotspots \u2014 so all-reduce traffic, which dominates multi-node training, completes fast even at 512 nodes. RDP sizes the topology (oversubscription, spine count) to your supercluster. 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: 1.6 Pb\/s aggregate non-blocking at Sub-600 ns is sized to carry supercluster 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 strategic 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 multi-year TCO<\/strong> for your supercluster.<\/p>\n Integrates with the AI stack: the InfiniBand subnet manager, NCCL with SHARP and standard MPI, with fabric monitoring and telemetry.
