On October 12, 2026, the company unveiled its second-generation Structera X CXL memory expanders, the models 3406 and 3506.\n\nMarvell says they are the first devices in the industry to offer six memory channels for CXL 3.2. AI models keep getting hungrier for memory, so a bigger plate seems like a reasonable thing to build.\n\n## What Marvell actually announced\n\nThe headline upgrade is the channel count. The previous generation used a four-channel design, and the new parts move to six, a 50% increase in channels.\n\nCapacity is where the numbers get large. Each controller supports up to 9 TB of DDR4 memory or up to 6 TB of DDR5.\n\nThe devices support four-host connectivity over PCIe 6.0 x16 links, with maximum bandwidth of 256 GB/s. Up to four separate host systems can tap the same pool of expanded memory.\n\nThe new Structera X parts include inline LZ4 compression, which Marvell says boosts usable memory capacity by 2 to 3 times.\n\nThe devices are expected to enter sampling by Q1 2027. Before that, Marvell plans live demonstrations at the OCP Global Summit, running from October 12 to October 15, 2026.\n\n### AI, tech, and the markets they move—in one daily briefing.\n\nDaily. Free.

Marvell is pitching the new Structera X lineup as a way to meet those rising KV-cache demands.\n\nCXL lets servers attach additional memory beyond what sits directly alongside the processor, and Marvell’s devices are built to comply with the CXL 3.2 version of that standard.\n\n## Building on an existing product line\n\nThe company started its CXL product line in 2024, with the goal of easing bandwidth and capacity limits in cloud and AI workloads.\n\nThe first-generation Structera X models, the 2404 and 2504, have already shipped to hyperscalers. Product updates for that generation are continuing into 2026.\n\nThe Structera portfolio covers expansion (the X line), acceleration (the A line), and switching (the S line). The new 3406 and 3506 slot into the expansion side of that lineup as successors to the parts that already made it into hyperscaler deployments.\n\n## What this means for Marvell and the AI hardware market\n\nAccording to the research findings, CXL technology is shifting from evaluation toward production.\n\nThe new devices are only expected to sample by Q1 2027, and sampling is an early step before volume production. The 2 to 3 times effective capacity from LZ4 compression will also depend on how compressible a given workload’s data is, so real-world results at customer sites will be the true test.\n\nThe OCP Global Summit demonstrations offer an early look, while the sampling window in Q1 2027 will show whether hyperscalers are ready to move from interest to orders.\n\n**Disclosure:** This article was edited by Diego Almada Lopez.
