The new CXL 2.0 Type 3 expansion card delivers flexible DDR5 memory scaling via PCIe Gen 5, addressing
latency and space constraints in edge and micro data center environments.
Innodisk, a leading provider of industrial-grade memory solutions, announced the CXL Add-in Card (AIC), a
major addition to its CXL product portfolio. Innodisk developed this CXL-based expansion card in response
to rising memory demands in next-generation computing and the limited scalability of current motherboard
designs. Connecting via the widespread and mature PCIe interface, the CXL AIC delivers fast memory
access without occupying system DIMM slots. It also provides greater flexibility in memory usage and
allocation. Its HHHL form factor, paired with Innodisk’s compact DDR5 RDIMM/RDIMM VLP, unlocks new
possibilities for micro data centers and edge systems, especially in latency-critical scenarios such as 5G
networking, high-frequency trading, and smart medical imaging.
Flexible Memory Expansion Up to 256GB
The Innodisk CXL AIC features two onboard RDIMM sockets that provide flexible memory expansion up to
256GB (128GB x2), allowing easy capacity adjustment by swapping RDIMM modules based on system
needs. By connecting through PCIe slots, it not only preserves the system’s native DIMM slots but also
delivers an additional 32GB/s of bandwidth via its PCIe Gen 5 x8 interface. This minimizes latency when the
CPU accesses shared memory, enabling faster data flow for bandwidth-intensive applications such as AI
inference and edge processing.
CXL 2.0 Capabilities for Dynamic Workloads
As a CXL 2.0 Type 3 memory expansion solution supporting CXL.mem and CXL.io, the Innodisk CXL AIC
not only reduces system latency and complexity but also enables memory pooling across multiple hosts,
improving overall system efficiency. This makes it particularly well-suited for applications with fluctuating
workloads, such as 5G networking and high-frequency trading in financial markets.
Compact Design for Edge
The Innodisk CXL AIC comes in a compact HHHL form factor with an additional FHHL bracket included,
ensuring compatibility with various chassis configurations. When paired with Innodisk DDR5 RDIMM VLP
memory, it further minimizes space requirements and enhances internal layout flexibility. This optimized
design is ideal for space-constrained edge servers and deployments where every inch matters.
A Configurable and Cost-Effective Solution
Building on its leadership in industrial DRAM modules, Innodisk offers the CXL AIC with configurable RDIMM
specifications to meet diverse customer requirements. It serves as a reliable, cost-effective edge solution for
memory expansion that eliminates the need for expensive motherboard redesigns as system requirements
continue to grow.
Scheduled for release in Q1 2026, the CXL AIC reinforces Innodisk’s commitment to delivering innovative
memory solutions that advance edge AI applications.
