Marvell adds six memory channels to CXL expanders for AI servers

Marvell announced the Structera X 3406 and 3506 CXL memory expander controllers, which add six memory channels and support up to 9TB of DDR4 or 6TB of DDR5 for AI servers, with sampling expected to begin in Q1 2027. The controllers are designed to expand memory capacity and share it across multiple hosts, extending Marvell's data-center silicon line into CXL memory expansion. Marvell's capacity and inference gains remain company claims, and customer adoption and workload-specific results will determine whether the design translates into meaningful business.

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. Marvell 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.…
