The story
Oracle redesigned its cloud infrastructure with Gen 2 OCI, implementing a strictly non-blocking flat network architecture that avoids oversubscribed packet routing between data centers. Connecting dozens of commercial and sovereign government cloud regions across five continents, the OCI backbone features redundant dark-fiber routes and dedicated fast transits. The high-throughput, predictable-latency topology provides the foundation for massive NVIDIA GPU clusters running RDMA over Converged Ethernet (RoCE v2) across hyperscale campuses.
Notable
- Engineered around a flat, non-oversubscribed spine-and-leaf Clos network design across all global regions.
- Supports ultra-low-latency RDMA interconnects for high-performance computing and multi-thousand GPU AI clusters.
- Operates dual-redundant private trans-oceanic and trans-continental paths linking over 45 cloud regions.
- Guarantees performance and latency metrics under industry-first comprehensive network SLAs.
