Marvell Technology, Inc., a leader in data infrastructure semiconductor solutions, launched the Marvell® Structera™ product line of Compute Express Link devices that enable cloud data center operators to overcome memory performance and scaling challenges in general-purpose servers.
To address memory-intensive applications, data center operators add extra servers to get higher memory bandwidth and higher memory capacity. The compute capabilities from the added processors are typically not utilized for these applications, making the servers inefficient from cost and power perspectives. The CXL industry standard addresses this challenge by enabling new architectures that can efficiently add memory to general-purpose servers.
The Structera product line comprises two CXL device families that are optimized for different use cases. The Structera A CXL near-memory accelerators are a new category of devices that integrate server-class processor cores and multiple memory channels with CXL to address high-bandwidth memory applications such as deep learning recommendation models (DLRM) and machine learning. The Structera X CXL memory-expansion controllers enable terabytes of memory to be added to general-purpose servers and address high-capacity memory applications such as in-memory databases. The Structera CXL device families are the industry’s first to support four memory channels, integrate inline compression and use 5nm manufacturing processes.

The Structera A accelerators integrate 16 Arm® Neoverse® V2 cores and are optimized to improve the performance of high memory-bandwidth applications such as DLRM. DLRM is characterized by both sparse and dense memory operations. Sparse operations may hit a memory wall, in which memory bandwidth is insufficient for the available compute. The Structera A 2504 accelerator, the first product in the family, supports up to 200 GB/sec memory bandwidth and 4TB of memory capacity1.
The Structera X product family, by contrast, is designed for expanding memory capacity per server to address high-capacity memory applications. The Structera X devices are the industry’s first to support four channels of DDR4 and DDR5 memory and support up to three DDR4 dual in-line memory modules (DIMMs) per channel (3DPC) for maximizing memory capacity per controller and server node. The devices are also the first CXL memory-expansion products that can simultaneously support two server CPUs to optimize power, space and memory utilization.
