Its headline capacity and inference gains remain company claims, and the chips are not expected to sample until Q1 2027, so customer adoption and workload-specific results will determine whether the design translates into a meaningful business.\n\nMarvell is adding six memory channels to its CXL expanders for AI servers. Sehat Sutardja, Weili Dai and Pantas Sutardja founded [Marvell](https://www.marvell.com/?ref=runtimewire) in 1995 around specialized silicon for hard drives. The new Structera X 3406 and 3506 controllers are designed to expand memory capacity and share it across multiple hosts; Marvell expects them to begin sampling in Q1 2027, rather than shipping broadly today.…", "url": "https://wpnews.pro/news/marvell-adds-six-memory-channels-to-cxl-expanders-for-ai-servers", "canonical_source": "https://runtimewire.com/article/marvell-structera-x-six-channel-cxl-memory-expanders", "published_at": "2026-10-12 15:25:04+00:00", "updated_at": "2026-10-12 16:19:10.976146+00:00", "lang": "en", "topics": ["ai-infrastructure", "ai-chips", "ai-products"], "entities": ["Marvell", "Structera X 3406", "Structera X 3506", "Sehat Sutardja", "Weili Dai", "Pantas Sutardja"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/marvell-adds-six-memory-channels-to-cxl-expanders-for-ai-servers", "markdown": "https://wpnews.pro/news/marvell-adds-six-memory-channels-to-cxl-expanders-for-ai-servers.md", "text": "https://wpnews.pro/news/marvell-adds-six-memory-channels-to-cxl-expanders-for-ai-servers.txt", "jsonld": "https://wpnews.pro/news/marvell-adds-six-memory-channels-to-cxl-expanders-for-ai-servers.jsonld"}}
