What it is
InfiniBand, dominated by NVIDIA's Quantum switches (from the Mellanox acquisition), is the incumbent scale-out fabric connecting GPU servers into large training clusters via RDMA with very low latency and in-network computing (SHARP). Quantum-X800 delivers 800Gb/s per port for Blackwell-era clusters. It competes with Ethernet-based AI fabrics (Spectrum-X, Ultra Ethernet), which are gaining share for cost and openness at hyperscale.

Times are New York time. Free sources are pulled on the schedule shown by the pipeline runner (data/corpus/run_pipelines.py), which logs every run; paid sources run only with the owner's yes; filings and newsroom pages are re-read when a new document is filed.
Links come from the AI Systems Map ontology. Deals carry the filing's own wording and a quote, checked against the document; latest source 2026-10-26. Not investment advice.
