Marvell has taken another step in expanding the Compute Express Link (CXL) ecosystem. Its Structera controllers and accelerators have now been tested with DDR4 and DDR5 memory from Micron, Samsung, and SK hynix. That follows earlier validation on AMD EPYC and Intel’s 5th Gen Xeon processors, giving Structera the unusual position of working across both major CPU platforms and all three of the big DRAM vendors.
Why Interoperability Matters
The promise of CXL is straightforward: give CPUs, accelerators, and memory devices a way to share resources with minimal latency. For engineers building data-centre hardware, that only works if the parts play nicely together. Being able to qualify hardware once and deploy it with confidence across different suppliers can cut risk and shorten the path to production.
It also matters for supply chains. Having options from multiple DRAM vendors, instead of being tied to one, means OEMs and hyperscalers can scale memory capacity without worrying about single-supplier bottlenecks. With memory demands already stretching into the multi-terabyte range, flexibility is as valuable as raw performance.
Inside Structera
The Structera portfolio splits into two main lines. Structera A devices combine 16 Arm Neoverse V2 cores with several DDR channels and CXL, aimed at high-bandwidth workloads such as deep learning recommendation models. Structera X, on the other hand, focuses on adding memory capacity to general-purpose servers, making it suitable for in-memory databases or other applications where capacity outweighs compute.
Both lines use a 5 nm process, support four memory channels, and build in inline LZ4 compression. The hardware isn’t just about capacity, but about efficiency when those systems are pushed hard under AI and HPC loads.
Industry Direction
For years, CXL has been talked about as the way to reshape data-centre memory. What we are seeing now is the ecosystem proving it can actually work across the vendors that matter. Validation with Intel, AMD, and the three leading DRAM suppliers makes Structera one of the most complete implementations to date.
Marvell is also offering the technology as IP, which means it can be integrated directly into custom silicon. That could give designers the option of embedding CXL into workload-specific SoCs or accelerators rather than relying on discrete controllers.
Looking Ahead
For system architects, the takeaway is straightforward. CXL is moving from theory to practice, and interoperability is no longer a sticking point. Structera provides one of the first examples of a platform that can slot into different system designs without heavy qualification work.
As AI and high-performance computing continue to push memory requirements, expect to see more of these cross-vendor validations become the baseline rather than the headline. For now, Marvell has given engineers a clearer view of how CXL hardware might be deployed at scale.
