The company's 12.8T power-optimized switch targets a market where spine switches are moving to 51.2T+, raising questions about market demand and Broadcom lock-in under SONiC.", "body_md": "Anyone heard or xsight labs (https://xsightlabs.com/)? They are making networking gear for AI and spacex satellites. I'd be curious if anyone can shine a light on:\n\n- Does full switch programmability actually matter in production, or is it one of those things that sounds great in a slide deck but nobody uses?\n\n- Is \"on-path cores\" in a DPU genuinely better than Pensando's P4 approach or NVIDIA's off-path model, or does it converge at scale?\n\n- Can you actually swap merchant silicon under SONiC in practice, or is Broadcom lock-in deeper than the software layer?\n\n- Is there a real market for a power-optimised 12.8T switch when the spine is moving to 51.2T+, or does the spine vendor always drag the leaf along?\n\n- How big a deal is open-sourcing the ISA? Do people buying this really care to pay up for this type of thing?\n\nThanks!!\n\nComments URL: [https://news.ycombinator.com/item?id=48838806](https://news.ycombinator.com/item?id=48838806)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/ask-hn-what-do-you-think-of-xsight-labs", "canonical_source": "https://news.ycombinator.com/item?id=48838806", "published_at": "2026-07-08 23:30:20+00:00", "updated_at": "2026-07-08 23:42:04.776145+00:00", "lang": "en", "topics": ["ai-infrastructure", "ai-chips"], "entities": ["Xsight Labs", "SpaceX", "Pensando", "NVIDIA", "Broadcom", "SONiC"], "alternates": {"html": "https://wpnews.pro/news/ask-hn-what-do-you-think-of-xsight-labs", "markdown": "https://wpnews.pro/news/ask-hn-what-do-you-think-of-xsight-labs.md", "text": "https://wpnews.pro/news/ask-hn-what-do-you-think-of-xsight-labs.txt", "jsonld": "https://wpnews.pro/news/ask-hn-what-do-you-think-of-xsight-labs.jsonld"}}
