InfiniBand: High-Performance Network Interconnect

InfiniBand provides high-bandwidth, low-latency networking for multi-node inference. Used by NIXL for KV cache transfer. Supports RDMA for direct GPU memory access. Key for disaggregated inference serving. | DEAD-LINK VERIFIED 2026-10-04. THREE independent GET probes: the mellanox.com URL 301-redirects to network.nvidia.com/products/infiniband and THAT also returns HTTP 404 ('404 Not Found', Apache-served, 196 bytes). So the content died after the redirect, not before it - the classic case where checking only the pre-redirect status would have scored this as live. Mellanox was folded into NVIDIA and its documentation moved into the NVIDIA Networking portal. The InfiniBand/RDMA/NIXL claims are architectural background, not a figure, and survive the move. | 2026-10-05 REPAIR: REPAIRED - URL REPOINTED TO A LIVE REPLACEMENT. The old mellanox.com/products/infiniband 301-redirected into a second 404 at network.nvidia.com/products/infiniband (the after-redirect death this record already diagnosed). The live NVIDIA Networking page is https://www.nvidia.com/en-us/networking/products/infiniband/ - note the inserted 'products' segment. HTTP 200, and CONTENT VERIFIED: it is titled 'The NVIDIA Quantum InfiniBand Platform' with Introduction/Products/Capabilities/Software/Resources sections and 9 InfiniBand mentions in the body, i.e. the interconnect product page this record claims Mellanox used to host. The architectural claims (high-bandwidth low-latency fabric for multi-node inference, RDMA direct GPU memory access) survive the vendor consolidation; Mellanox's site is now wholly a redirect shell into NVIDIA Networking.
