AI clusters scale, data center networks are being pushed to their absolute physical limits.#
Netnod Tech Meeting 2026 digest Program Core pick 6 October 2026
Speakers: not listed in the program.
- Why: This is squarely the PM's physical-DC core interest — AI/ML workloads are the current forcing function on fabric design, optics, cabling, and power, and this is the meeting's dedicated session on where those limits actually break.
- What: A talk on how AI cluster scale is stressing datacenter networking past its physical limits. (from title only)
- How: Unknown; likely covers the usual pain points at this scale — lossless/RDMA-capable fabrics, optics reach and power density, topology (rail-optimized/flat) choices — but this is inference from the title, not confirmed content.
- Where applicable: Relevant to anyone building or evaluating AI-scale fabrics; the specific breaking points cited will likely depend on the speaker's silicon and scale assumptions, so check those when watching.
